New Tab mix plus for modern Firefox

---

Tab Mix Plus is a very popular legacy extension for the Mozilla Firefox browser that enhances Firefox's tab browsing abilities. It includes such features as duplicating tabs, controlling tab focus, tab clicking options, undo closed tabs and windows, plus much more.

Session Manager feature is not included at the moment since it requires complete rewrite.

If you are interested in keeping Tab Mix Plus working, please donate.

Installation

1. Legacy extensions loader
   Since Firefox removed the internal component that loads legacy extension, in order to install Tab Mix Plus, or any other legacy extension, you have to install 3rd party helper scripts.

   1.1. Open about:support and locate the path to your Application Binary and Profile Folder.

   screenshoot

   

   1.2. Install configuration files to your Application Binary folder.

   fx-folder.zip files are packed with paths used by Firefox for Windows, Linux and MacOS users should follow the instructions below.

   Linux

   Note: The default path to Firefox on Linux is typically /usr/lib/firefox/.

   Verify the path:

   Check the actual path to your Firefox Application Binary. If it differs from /usr/lib/firefox/, replace the path accordingly in the following instructions.

   Copy the configuration files extracted from fx-folder.zip:

   • copy config.js to /usr/lib/firefox/config.js
   • copy config-prefs.js to /usr/lib/firefox/browser/defaults/preferences/config-prefs.js
   Linux with Snap

   Compatibility Note:

   Firefox snap for Linux versions prior to 108 are not supported.

   Instructions for Firefox snap 108 or newer

   Verify installation path:

   If you're uncertain about the installation path of your Firefox snap, use the command snap list firefox in your terminal to check.

   Copy the configuration files extracted from fx-folder.zip:

   • copy config.js to /etc/firefox/config.js
   • copy config-prefs.js to /etc/firefox/defaults/pref/config-prefs.js

   Create subfolders if necessary

   If the folders /defaults or /pref don't exist within /etc/firefox/ create them.

   MacOs

   Note:

   The default path to Firefox on MacOs is typically Firefox.app/Contents/Resources.

   Verify the path:

   Check the actual path to your Firefox Application Binary. If it differs from Firefox.app/Contents/Resources, replace the path accordingly in the following instructions.

   Copy the configuration files extracted from fx-folder.zip:

   • copy config.js to Firefox.app/Contents/Resources/config.js
   • copy config-prefs.js to Firefox.app/Contents/Resources/defaults/pref/config-prefs.js

   1.3. Create chrome folder in your Profile Folder (if one does not exist).

   1.4. Extract utils folder inside the chrome folder, the result should be [PROFILE_NAME]/chrome/utils, all the files should be in the utils folder (see the screenshot below).

   screenshoot

   

   1.5. Open about:support page and click "Clear startup cache…" to force Firefox to load the installed scripts on the next startup.

   1.6. Start Firefox again.

   1.7. Follow the instructions below to install Tab Mix Plus.

2. Download XPI

   Download xpi file from our releases page to your local computer.

   All Tab Mix Plus downloads are also located here.

   If you are using Firefox Beta, Developer Edition or Nightly we recommend using the latest Tab Mix Plus development build (tags with pre or test-build in the title)

3. Install XPI

   To install the file you have just downloaded:

   • Open Add-ons Manager tab (about:addons) and select Extensions.
     or
     Click the menu button ☰, click Add-ons and Themes and select Extensions.
   • To add the downloaded add-on to the list of available add-ons, drag and drop the file into the Add-ons window. The add-on is added to the list.
   • The installation process should begin.

Troubleshooting

If Tab Mix Plus stops working after Firefox update was installed or when you try to install Tab Mix you get a message that it appears to be corrupt, follow these instructions

• Uninstall Tab Mix Plus.

• Close Firefox and reinstall the latest versions of these scripts (see instructions above):

  • Install configuration files to your Application Binary folder.

  • Extract utils folder to chrome in your in your Profile Folder.

• Some users report that their Firefox is not able to install or use Tab Mix Plus unless they set extensions.experiments.enabled to true in about:config.

• Open about:support page and click "Clear startup cache…" to force Firefox to load the installed scripts on the next startup.

• After Firefox starts Reinstall latest Tab Mix Plus again.

Browser Compatibility

• Firefox 78 - Firefox Nightly
• Waterfox G3 - G6 and beyond

For Pale Moon download Tab Mix Plus from here

Configuration

Tab Mix Plus comes with Options window that includes all of its preferences as well as adding user interface to important Firefox hidden preferences. It is recommended that you make all changes to the preference in the options window. The options window is available from the Add-ons Manager or from the Tools menu (unless you turn this option off).

Cannot open any entries from the Library window

Opening from the bookmarks toolbar, or library pop-up pane works (although history doesn't remember the container but I don't know if that's related to TMP)

Firefox now has built-in spacers in tittle bar while window not maximized

TabMixPlus/addon/chrome/skin/general.css

Lines 66 to 67 in f601e73

	/* :::: Space on tab bar :::: */
	#tabbrowser-tabs[tabBarSpace] > .tabbrowser-arrowscrollbox {

change

#tabbrowser-tabs[tabBarSpace] > .tabbrowser-arrowscrollbox

to

#tabbrowser-tabs[tabBarSpace] > #tabbrowser-arrowscrollbox 

Will make the "Extra spaces on both sides" option function but it does look awkward when the browser window is not maximized.
May be adding more rules to take built-in spacer into consideration or directly manipulate them.

My Firefox Developer Edition 87.0b5 is not loading bootstrap addons right

I'm trying use multiple bootstrap addons and found that browser startup have a big chance been interrupt and hangs especially when having more than one addons enabled and restore a session. (most of the UI are loaded but not the tabs of restored session, tool bar button's menu, booksmark bar items)
I'm using script loader for addons.
And Tab Groups just not been loaded while browser start.
Are you seeing any of this?

Addons:
roomybookmarksredux
TMP
Tab-Groups

We still need to fix tab bar buttons themselves

2 out of 3 not working right.

It's look like the Inner structure of the tab may change. Which may lead to requirement of update our 'tab binding' in future.

Tab relation detection not working

Due to the change of the Firefox we now no longer have a referrerURI in params.
referrerInfo seems replaced it.

New Tab options are broken

Two are broken options are broken

1. setting/resetting custom New Tab Page (browser.newtab.url) not working.
   This function throw an error on both option. Tabmix not working at all when Firefox start with browser.newtab.url not as "about:newtab"

Error when using data-l10n localization

when window start i see this error in the console

23:11:16.682 [Exception... "Component returned failure code: 0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH) [nsIXPCComponents_Utils.readUTF8URI]"  nsresult: "0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH)"  location: "JS frame :: resource://gre/modules/L10nRegistry.jsm :: L10nRegistry.loadSync :: line 692"  data: no] 2 L10nRegistry.jsm:692:19

The error when loading the preference window, Uncaught (in promise) undefined also related to l10n.
when i removed all data-l10n attribute from the xhtml files (menu.xhtml, mouse.xhtml) the error is gone.

However Firefox stile crashing when loading from Add-ons page so it probably not related.

MergeWindows - Place popups next to their openers not working

TabMixPlus/addon/modules/MergeWindows.jsm

Line 135 in 316280c

let openerTab = tabbrowser._getTabForContentWindow(openerWindow);

@117649 ,

Old code to Place popups next to their openers does not work.

1. the function gBrowser._getTabForContentWindow was removed.
2. "Tabmix:collectOpener" content message listener does not work.

using browser.ownerGlobal.opener return ChromeWindow and i don't know how to get the opener tab from it
let me know if you can find solution to this issue.

I can also remove this option and just merge popup window at the end

Merge Windows in tab context menu not working

Error:

    oncommand chrome://browser/content/browser.xhtml:1

'Services.wm.getZOrderDOMWindowEnumerator' is no more but there is a 'Services.wm.getZOrderAppWindowEnumerator'.
I'll bet they just change the name.

Removed: Reload skip cache – for bookmarks open in tabs

I have just removed this feature (commit a0c1fca)

Reason for removing it:

• it does not work!!, and throw an error:

    [Exception... "Component returned failure code: 0x80004001
    (NS_ERROR_NOT_IMPLEMENTED) [nsIRequest.loadFlags]"  nsresult:
    "0x80004001 (NS_ERROR_NOT_IMPLEMENTED)"  location: "JS frame ::
    chrome://tabmixplus/content/tab/tab.js :: TMP_onStateChange ::
    line 2660"  data: no]

• it was only used by:
  • our session manager that now doesn't work.
  • when user open group of bookmarks while the feature Load tabs progressively was on.

@117649, i don't find important but if you know about a simple fix let me know.

Add option to toggle compact mode for tab height

We can add option to toggle compact mode for tab height, with a simple checkbox.
compact: preference browser.uidensity = 1
normal: preference browser.uidensity = 0

Currently in Firefox 91 the value for compact height is 29px.

We can also add slider to allow the user to set custom height, values can be from 21px to 40px

event.target.localName not match tab or tabs

event.target.localName gBrowser.tabContainer no longer match tab or tabs

we need to scan the code and replace event.target.localName with the proper value
some of the issues related to #21 and #26 caused by this issue

Firefox crashing when loading Tab Mix options from Add-ons

Firefox crashing when loading Tab Mix options from Add-ons:
it crash when trying to open options from this view (all extensions):

but it work OK from extension view (only Tab mix):

Originally posted by @onemen in #17 (comment)

I think i have a fix for this issue.
The problem is in aboutaddons.js, we add click event for the option button after load event and from MutationObserver.
when you open Add-ons tabs for the first time both load event and mutation add click listener to the button.
when we click it both listeners runs and Firefox try to open the same window twice

It work for me with this patch, if it look right to you i will commit it

Be careful with prefs-ce.js

I've just tried packing a new .xpi from rewrite/main after some css change. And the add-on option dialog window broken thus I have to revert most changes done on the 'prefs-ce.js'
Since the old add-on dialog is planed to be replaced may be just leave the file as it is.

there are others without a min.

@117649 can you take this one ?

Can we remove progress meter on tabs?

I think that progress meter on tabs is obsolete.
with the new design of burst animation it have no real value to the user.

according to my testing, for most of the tab the progress value get at most 2 hits, the value change from 0 to 50% to 80% and 100%. it also happens to fast to be visible.

Maybe we can improve the code to get move visible update, but it stile think that we don't really need it.

TMP can't set tab max/min width while option dialog is not in instant apply mode.

I mean the value on dialog is changing but it not been sync to preferences.
Have to switch to instant apply mode fro things to connect.

Tab not retain auto reload setting after been restored

Tittle. May relate to session manager.

How to use extension from folder on development

In the good old days before Webextensions I could place a file in profile/extensions folder with a link to my working directory.
that configuration eliminate the need to create XPI file and install it after each change

for extension with id [email protected] the file name was the same as the id ([email protected])
and its content was

path\to\working\direcory

Is it possible to do the same with Firefox nightly when using helper loader ?

Now check 'all tabs button' box hide the button for me and vies versa

I have Tab-Group installed which cause 'all tabs' button show at first.

How to use helper loader

@117649, you post this on #3

For the Firefox versions compatibility it is a little bizarre situation here:

1. For the latest Waterfox G3 which is based on Firefox 78ESR the compatibility should just be straightforward.

2. You need a [helper](https://github.com/117649/firefox-scripts) to load the bootstrap legacy add-on, Waterfox already came with one.

3. The helper came in two types [extension](https://github.com/117649/firefox-scripts/tree/master/extensions/bootstrapLoader) and [script](https://github.com/117649/firefox-scripts/tree/master/chrome/utils). I would consider the one waterfox provided is script type.

4. The two types of the helper CAN co-exist BUT SHOULD NOT since this will cause two helper in the browser and load every bootstrap legacy add-on twice. Which will cause problem.

If i understand it correctly, the user of Tab Mix Plus will have to install the helper loader (script or extension), we are not going to wrap the loader with Tab Mix xpi file

Can we make gBrowser.tabContainer._lockTabSizing optional?

After first tab is closed.

new tab button on tabs bar not displayed right while option set to "After last tab"

If the tabs is overflowing the new tab button will not show.
At this moment disable and re-enable the option would cause new tab button show on right of the tab bar and it will stay on there even if tabs stop overflow.
Stop overflowing disable and re-enable the option can make new tab button show after last tab.
Found out that when disable then re-enable the option the attribute would be set to "right-side" regardless what the menu selection is while tab bar is overflowing.

I think we should keep an eye on the Mozilla's proton

https://www.ghacks.net/2021/01/02/mozilla-is-working-on-a-firefox-design-refresh/

It's look like the Inner structure of the tab may change. Which may lead to needs of update our 'tab binding' in future.

Enable auto update

@117649 , i'v noticed that you don't have updates.json in your repositories Tab-Groups and Saved Password Editor Redux is there any other why to enable auto update for bootstrap extensions?

We need to update the link in install.rdf and the content of updates.json to Github urls

window.BrowserUtils.restartApplication is not a function

After notification from tabmix that it need to restart i get this error message in the console

window.BrowserUtils.restartApplication is not a function bootstrap.js:35

Merging codes that is greatly different between old and new.

So, this:

Any ideals?
