firefox 55 breaks all extensions 54 was fine. Tested with fresh vm, repeatable. 54 and below all my extensions lastpass, greasemonkey, tabmixplus etc all work. Tried installing them with fresh VM and they work. Update to 55, ALL extensions break.

Current fix is to stay at version 54.

LastPass has released a beta version that most users report is working with Firefox 55: https://addons.mozilla.org/firefox/addon/lastpass-password-manager/versions/beta

I am not having problems with Greasemonkey version 3.11. However, I do not have multiprocess enabled, which might make a difference.

If you require Firefox 54, you should use the last release version (54.0.1) instead of the beta 9 test version your Firefox indicated it is.

I'll try 54.0.1

Is there a way to get my extensions to work properly above this version?

Why are you using an old Firefox 54.0b9 beta version and not the Firefox 54.0.1 release or the Firefox 52.3.0 ESR version that is still maintained with updates?
