Firefox - not allowing add-ons

Has there been a recent update to Firefox? Suddenly none of my add-ons will work with Firefox. I use duckduckgo for my search engine and when I go to their page it has an "add duckduckgo to Firefox" box. When I click to add it I get the message that the file is corrupt. This is the same message I get for all the add-ons when I try to install them.
So, either Firefox made some update or I got one of rare Linux malwares!

Re: Firefox - not allowing add-ons

This is a Mozilla f'up. They have messed up a security certificate and so this is the result.

The reported fix to go to about:config and set xpinstall.signatures.required to false doesn't work for me.

https://blog.mozilla.org/addons/2019/05 … n-firefox/ contains an update advising users to enable Studies in settings and then just wait till it is fixed by Mozilla via that tool.

Or Install a different browser such as Slimjet, etc.

Re: Firefox - not allowing add-ons

Firefox disables all add-ons, as described by bin above. Please read https://www.dedoimedo.com/computers/fir … d-bug.html for an explanation and a possible fixes.

Re: Firefox - not allowing add-ons

Thanks Bin and Q4OSteam! I did go to the Firefox home page and didn't find anything about the issue.
After reading the link I think I'll give them a few days to fix it.

I'm not sure if it will help but I just read this post in the debian user forum which might be of use to you.

Re: Firefox - not allowing add-ons

I went ahead and took the chance. I made the manual modification and it seems to have worked. Thanks to all that gave tips.

Re: Firefox - not allowing add-ons

Mozilla have updated their info about the fix for this issue - it looks like a new release is coming down the pipes.

Re: Firefox - not allowing add-ons

Fixed ESR version (60.6.2) is already in the repositories, but what about fixed Ubuntu version (66.0.4)? The Q4OS repositories still offer only the 66.0.1...
