UPDATE: I just learned that Super Start is no longer compatible to firefox. What a pity. So how can I get my old firefox back???? (I know... not safe enough...) At least it still works as start page.
Original issue:
Once again firefox was destroyed by an update. sigh (I know! They have their reasons...)
Some time ago I had to install newtaboverride to get Superstart back on new tabs. Now even this doesn't work. Or at least I don't manage to get it done.
I read this in the comments on newtaboverride: "In order to use Superstart extension, you can go to about:config, look for extensions.superstart.enable.searchengine.select and change the valor to true. This way, you can make work your about:superstart custom url despite the http://."
I set all superstart valors to "true". But as soon as I insert WHATEVER in the field in newtabboverride, firefox would not open ANY new tab. I tried "about:superstart" but even with "about:blank" the same thing happens.
So I get only new tabs that are completely empty or I get no new tab at all. :-((
PLEASE help me! I am a "many tab personality", leave them open all the time!
