As of last night, my Logitech mouse's custom functions no longer seem to function with Firefox, and only button defaults are working.

This seems to be regardless of restarting/updating Firefox, computer restart, etc. Works everywhere else on the computer just fine, and giving Firefox specific custom functions with Logi Options+ doesn't fix the issue. Anyone have any idea what's going on or if there could be a work-around? Would be incredibly thankful of even just any info of what could be going on.

On Windows 10, mouse is M510 if it's relevant.
