@gjacobse said in Firefox Add-ons v55 and future:

It seems that a number of common Add-ons or Extensions for Firefox have become 'Legacy' since the release of v55.

Ad-blocks Bookmark Backup other useful tools
NoScript uBlock LastPass (Can't see anything in Show Matching Sites) Magic Actions for YouTube (Seems to not work well with the new YouTube)
