Hmm, don’t think you should need to compile it yourself? They offer downloads for Windows and macOS, and on Linux, the normal Firefox from the distro sources generally already has this compile flag enabled, as far as I know.
I mean, I actually never had a need for unsigned extensions, so never tried it myself, and obviously I wouldn’t know, if every single distro does it the same.
As for wanting to contribute to the statistics, I do understand that desire. But I believe, for the most part, it’s the user agent that counts. I doubt, they would set that to something else in the unbranded builds…









Can you launch the original executable by itself?
So, if you run the command, that you put into the
.desktopfile, in a terminal, does that work?
