I have used Firefox for web development since forever. The recent major update has absolutely turned my world upsidedown. 95% of my numerous, essential addons no longer working, tab groups vanished, keyboard shortcuts scuppered.

While I appreciate the moves towards speeding it up etc, it's nonetheless a goddam scandal.

I wonder if anyone else is facing similar problems. Any solutions?

Stay on 52 esr edition.

@nbamaral Yeah. That's what I've gone with.. downloaded 54 from the archives and disabled all updates. Can only see this becoming more of an issue though. No tab groups in particular is a fucking scandal

@nbamaral Oh- I've just looked up "esr"- that's a great idea, thanks, downloading now!

I got lucky with Addons.

Still wish Vivaldi had a working sync feature.

@Inigo
You'll be good with esr until April 18 I think :)

@JonnyCodewalker Yeah, the vast majority of them are nuked.

But no worries, 52 esr is doing the job fine, and with any luck by April 2018 the new Firefox will actually be something close to usable again. I hope.

@JonnyCodewalker A few examples I can't live without: Tab Groups, Tab Groups Helper, VimFx, Highlight Tabs, Multiple Tab Handler, Measure it.... to name a few.

All of them nuked to dust.

...much to the chagrin of some of the developers, I gather. Have a read here: http://fasezero.com/lastnotice.html It does seem that the switch to using WebExtensions, while bringing the benefits of standardisation, will limit what can be done in terms of addon development.

The future of Firefox won't be the ultra customisable beast we once knew.

Thwre has been a flag in Firefox nightly for a while called legacyextensions (or something like that) which re-adds compatability. Not sure if its in beta or main release though.

@techy105 Yeah that seemed to come crashing down for me yesterday for some reason.
