Most of them.

LibreWolf is literally just the FireFox build, with the telemetry & adware ripped out, and ublock origin and similar preinstalled. (I suspect people that downvoted me above assume I am shilling some commercial browser and just don’t know what LW is)

I ran into a problem with Video Download Helper, it installs a co-app that had “~/.firefox” hardcoded in a script. I changed that to point to LibreWolf and it worked.
