The following example worked on macOS. If it worked for you too, you may have placed the files in an insecure directory.

package main

import (
	"log"
	"os"
	"path/filepath"

	"github.com/pkg/browser"
)

func main() {
	pathDirTmp, err := os.MkdirTemp(os.TempDir(), "sample_dir_*")
	if err != nil {
		log.Fatal(err)
	}

	pathFileTmp := filepath.Join(pathDirTmp, "sample_file.html")
	dummyContent := `<html><body>Hello World2</body></html>`

	// Create file under the temporary directory
	if err := os.WriteFile(pathFileTmp, []byte(dummyContent), 0644); err != nil {
		log.Fatal(err)
	}

	// Open the file in the browser
	// if err := browser.OpenURL(pathFileTmp); err != nil {
	// 	log.Fatal(err)
	// }

	// Open the file for reading
	osFile, err := os.Open(pathFileTmp)
	if err != nil {
		log.Fatal(err)
	}

	// Consume the contents and present the results in a browser
	if err := browser.OpenReader(osFile); err != nil {
		log.Fatal(err)
	}

	// Open the directory of the temporary file
	if err := browser.OpenURL(pathDirTmp); err != nil {
		log.Fatal(err)
	}
}

You said "you may have placed the files in an insecure directory"

But I am using it like this:

browser.OpenReader(response.Body)

This means, that I am not explicitly putting the content into a directory....

I had a look at how this gets handled by Python, but that's a huge file: https://github.com/python/cpython/blob/3.10/Lib/webbrowser.py

Sorry, I need to leave now. Feel free to close this, if you don't have time and energy.

@guettli

But I am using it like this:
browser.OpenReader(response.Body)

Yes yes, that's why the file pointer is passed like this.

osFile, err := os.Open(pathFileTmp)
** snip **

err := browser.OpenReader(osFile)
** snip **

My point was that "Where was the temp file created?"

The path "/tmp/browser.1293014077.html" seems to be insecure. For example, on macOS, temporary files are created in private/var/folders.

file:///private/var/folders/8c/lmckjks95fj4h_jqzw4v3k_w0000gn/T/browser.140875179.html

The /tmp/browser.1293014077.html contained the response.Body value, so it is assumed that the OS or the browser is blocking it for security reasons. Not sure.

Try using os.MkdirTemp() and os.TempDir() to store the value of response.Body in a temporary directory. Then open it and look at the difference in paths.

Feel free to close this, if you don't have time and energy.

Unfortunately, I'm only a passer-by to help and don't have the privilege to close this issue.
