Can't download add-ons to Firefox

[giddyup]

I just noticed that my Adblock and Adblocker icons have disappeared and that ads are no longer being blocked on Firefox. When I try to re-install them I get a message saying "download failed, please check your connection". Not sure why this is happening, please advise.

[wgdanson]

Swap back to Chrome then.

Seems FF are working on it.....

In 'about:config' enter: xpinstall.signatures.required, and set it to false. Problem solved.

That's why its better if you can to do your add blocking at the router level..

 

My Firefox was effected too...automagically disabled stuff ????

Firefox extensions check if the signature is correct, when that check fails the extension will not load.

 

This is a good thing, so you can't load an extension that is tampered with.

 

But on this occasion someone at Mozilla screwed up, and done something that forces all extension to be disabled. I

"So sorry for the issue we’re having with add-ons right now! We’re working hard to fix it and will keep you updated."

Probably good workaround solution as long as the users remember to turn the certification checks to true, once the problem is solved by Firefox.

When the update comes around, it will reset all settings to default, unless you've made a 'user.js' with your personal preferences.

But at the moment getting an error message about too many requests ????

Here's what's going on with your Add-ons being disabled, and how to work around the issue until its fixed.

I have zero regrets about ditching Firefox several years ago.  It became a vulnerable fat client, and the updates were always a crap shoot of trickery.

What's your OS? I don't seem to be having any problem with Ubuntu.

Hence you should use the ESR version of FF.

[donim]

After an update with my Firefox many add-ons were not supported anymore.

 

Had to disable a few, update some and for some have to delete and replace with another addons.

In Firefox you can set some 'false' flags to keep it working, another member already wrote that.

 

Adds and webpages are blocked on my router between internet and my local network.

with some exemptions giving revenues to the webowners,

no addblocks in the browser.

So each device get the same policy here.

I have a lot of manual About:config edits, and when an update to Firefox comes they have never been reset to default. And No, I don't have a User.js in my profile.  (Maybe a good idea to have one, but I never bothered)

 

And I (but I could be wrong) think that this will be dealt with Server Side (Mozilla) instead of pushing an Update to all users (but as already said, I could be wrong)

I can only tell you how I do it  and that is by installing Asuswrt-Merlin firmware  to my router

https://asuswrt.lostrealm.ca/

 

then installing an odd on called  "Diversion"   https://diversion.ch/

 

https://www.snbforums.com/threads/diversion-the-router-ad-blocker.48538/

 

Another way  is to have a custom host file running on your  device

for windows I use "hostman"     http://www.abelhadigital.com/hostsman/

After experiencing the same this morning I started migrating to Chrome.

Fed up with another round of disabled add-ons.

Oops, my apologies. Have started getting Firefox messages about disabled addons.

Sorry I asked, thought it was something simple. Thanks.

The "hostman" method is simple if you use Windows...but doesn't block at the router level so only protects the PC/device its installed on...

Same here, right after I let a Win10 Update go through.

Absolutely NOTHING to do with a Microsoft Update.

 

Someone at Mozilla (Firefox) made a mistake and thus Add-ons in Firefox stopped working.

(There is a work-around to get it working in the previous pages in this thread)

 

If it was a Microsoft Update other Browsers would have issues as while !

Just a coincidence then.  Yeah, uninstalled the update a while ago just to see what would happen.... nada.  Same issue in FF.  Thanks.

I got that MS update today as well, but AFTER the Firefox Issue, as I only manually check for updates in Windows not automatically

I read it only applies if you're using the Firefox Developer or Nightly build. It made no difference on my build.
