Sadly after using the about:config fix i still have my extensions disabled and no backup.

 

try this:

hmm cant seem to find extensions in C:\Users\

 

ahh found it now in roaming.

I disabled the extensions but I cannot find a box to re-enable.

finda replacement and remove are the only options

 

I read this earlier and thought user error right away. No kidding later today my uBlock and Bitwarden were gone from my Firefox. And when I tried to add it back in said some error. haha

 

Trott3r, I had the problem on multiple windows/linux boxes, including both esr and 66. I simply changed the xpinstall setting, restarted the browser, and things were back to normal. If you still don't see the addons, after making the xpinstall change, try installing them again (the settings should be preserved in your profile).

Tried the xpinstall setting first but no joy.

 

i've had it confirmed that it works with installed versions too. you need to do it precisely the way and in the order in my post, and use an admin account for that. remember to make the "extensions.json" file read-only. use windows search to locate the json file. and make sure you replace all of the "-1"s with "2" (no - before 2) and "true"s with "false" in that json file, there are more than one.

 

I have recovered from the FFF (FireFox Fiasco). Good grief -- I wonder if Mozilla plans to give us this kind of fun every week or so?

but i recommend you to start using ff portable. it's the best solution.

 

For me, just resetting Firefox (Menu > Help > Troubleshooting information) I was able to re-install addons again.

 

Following the information provided by lofac, I too was able to re-install addons. Haven't turned computer off and restarted it so am assuming they will still be there when I do. Thanks so much lofac for the information.

 

I've been using Firefox just about everyday since 2002 when it was called Phoenix. (That having evolved from Mosaic and then Netscape beginning early 1990-something using Windows 3 and SLIP dial-up.)

Some one at Mozilla was asleep at the switch (I'd hate to be That Guy/Gal.) and our precious, life sustaining extensions got disabled with the official temporary workaround being a click on a data collection checkbox. Yes, I know that would reveal to all the world what are your favorite knitting stitches forums. No matter. "They" already know.

Fully understanding nothing else anywhere anyhow anyway has never ever had any problems whatsoever, egregious blunders by Mozilla have been quite rare let alone fubar.

So, with at least 30,000 hours of flying teh Mozilla browser and with many, many of those hours kicking about:config and hammering Add-ons, rest assured my friend, the answer to your question is...

No.

 

The problem just hit me, but it seems a new 66.0.4 is out:

Thanks Mrk, your fix worked. And here was me praising Mozilla only yesterday. lol

Download Firefox in your language

There is none. First you have to select a subdirectory for the desired version e.g. win64, and then another subdirectory for language.

 

Me, too. Its current name, Firefox, actually should be "Red Panda". And, yes, my various editions of Phoenix/Firebird/Firefox have been 99.9% stable down through all these years. Before that, I was a Netscape groupie & a charter member of the ABIE Club (Anything But Internet Explorer).

 

That Guy/Gal more than likely is no longer working at Mozilla.

 

Why not? Someone who has never messed up is far more likely to become complacent. In my shop, if someone messed up, they got a closed-door "you've had it" chewing, then we kept them on. Those who appreciated a 2nd chance became extremely reliable. The repeat offenders were soon seeking jobs at McDonald's.

 

Surely something as critically important as security certificates couldn't possibly have just one person overlooking the project, could it?

 

hi
i have tried almost everything and this worked for me , maybe could be usefull for you , sadly i can't install other extension but it did activate all my installed extension

 

If you fire people for making mistakes, you will end up with zero-risk yesmen.
You should always blame the management, because they bear ultimate responsibility.
