Cannot switch profile

[kleinpetr]

I am not sure if this is directly related with the connector itself, of not feel free to move the issue, but out of nowhere the extension stopped working, when I inspect it, it shows these errors

Is there anything what I could try to do?

I hit the same error. Had to improve the logging a bit to figure out what the actual problem was. logging:

Native error! 
Object { success: false, error: "Unable to find browser binary!", debug_msg: "BinaryNotFound(\"NoCrashReporterEnvVar(NotPresent)\")" }

which means the environment variable MOZ_CRASHREPORTER_RESTART_ARG_0 isn't being set by the browser (at least in my case it seems to be missing)

It seems you can manually set the browser binary path by creating a file ~/.config/firefoxprofileswitcher/config.json with the following content:

{"browser_binary": "/usr/bin/firefox"}

This fixes it for me, but it's not very user friendly. I guess firefox changed something so that environment variable isn't passed to extensions any longer?

Can confirm the workaround to get this working.

I confirm the workaround works here. On Fedora 38 Stable with FF from the repo.

Can confirm on creating ~/.config/firefoxprofileswitcher/config.json... I am using Firefox Developer Edition installed on Kubuntu 22.04 via DEB package.

{"browser_binary": "/usr/bin/firefox_devedition"}

For Windows users, the config file would be %APPDATA%\nulldev\FirefoxProfileSwitcher\config\config.json.

{"browser_binary": "C:\\Program Files\\Mozilla Firefox\\firefox.exe"}

For MacOS:

echo '{"browser_binary": "/Applications/Firefox.app/Contents/MacOS/firefox"}' >~/Library/Preferences/ax.nd.nulldev.FirefoxProfileSwitcher/config.json

Chiming in because I've introduced the change that should have caused this. MOZ_CRASHREPORTER_RESTART_ARG_0 is not set anymore starting with Firefox 124 and ESR 115 too. The change was required to harden the crash reporter against potential exploits, I'm sorry it caused breakage.

This is still working!. At least on ArchLinux and firefox 127
