    All of a sudden my FireFox can't install add-ons and all of my add-ons are gone. Including AdBlock Plus which I like the most. This only seems to be happening on my Windows 8.1 64-bit system.

    I have FireFox up to date. It's version 66.0.3. All I can remember is that pages stopped loading temporarily and then it said my add-ons couldn't be verified and disabled all of them. It's not my anti-virus even though I have Avast. I have used Avast for several years now with no problems whatsoever. My computer was already scanned for viruses with MalwareBytes Free and Avast today and it didn't detect anything so it can't be a virus. I tried Restoring FireFox and that didn't work. I tried completely reinstalling FireFox and that didn't work. I tried doing a clean uninstall and re-install of Avast and that didn't work.

    I tried to get AdBlock Plus from here: https://addons.mozilla.org/en-US/firefox/addon/adblock-plus/

    All it says is: "Download failed. Please check your connection."

    My connection is perfectly fine as I wouldn't be able to post this if it wasn't. My FireFox connection settings are already on 'No Proxy'

    I haven't tried a System Restore yet and I really don't want to Restore to Factory Settings and I can't afford a new computer as I just recently became unemployed.

    Can someone help me fix this bizarre issue that occurred out of nowhere? I'd really appreciate any help with this. Thank you.

    If you need any other information please ask and tell me how to find it and I'll give it to you. Thanks again for the help.

    Wonderful. That means the same thing will happen to my Windows 10 laptop the next time I get on it. Because it has FireFox as well. So what do I do? Any suggestions? Wait for a fix and hope no malicious ads don't infect my computers with viruses?

    What should I do the next time I get on my Windows 10 laptop? Just ignore it and wait for the fix instead of all the insanity I just did on my Windows 8.1 desktop?

    AlwaysScrewed,

    It is not your computer. No need to "Restore to Factory Settings"
    I am having the same problem.
    It's Firefox.
    AdBlock Plus disabled and also McAfee WebAdvisor.
    Has Firefox finally gone over to the dark side and sold out to big business ?

    They suggest switching to "Firefox Nightly".

    Does anybody know anything about it ???

    I have no problem with ads on the internet. I know that ads are what keep the free sites free.
    I want to block all the thousands of ads that turn into malware and spyware once they are clicked on.
    I know how to avoid them, but many older users that are not smartphone users are very easily mislead or misdirected by these ads.............

    Anybody got another idea on a different browser to use ?
    No I am not using IE or Chrome.
    Someone suggested "Pale Moon", but it's site is full of malware ads too.

    Thanks.

    Same here. All of the above. Not a happy camper. Hope they fix it fast - before I uninstall it and fughetaboutit. I loved Firefox for not being "big box", but if they've gone that way, I'm done.

    Update, just saw on Engaget they're working on it: We're sorry that there is currently an issue where existing and new add-ons are failing to run or be installed on Firefox. We know what the issue is and are working hard to restore add-on functionality to Firefox as soon as possible. We'll continue to provide updates via our Twitter channels. Please bear with us while we get the problem fixed.

    I just reverted to FF 56 before the 'big update', as a temp work around.
    I get the same message about verification and disabling of extensions, but status stays the same and still seem to work.

    FF 62.03 also has the problem, so this problem has been 'wired' into FF for a while.

    And yet more secure this morning than FF 66

    Same. They need to fix it ASAP because I also really liked FireFox and I don't like the other browsers. FireFox was the best one IMO. Until this happened obviously. They'd better fix it fast. Otherwise I may have to do the temporary solution as well.

    Looks like add-ons are working again. I don't know if this is the 'temporary' fix or not but hopefully there will be a permanent fix. I guess this is resolved? Unless others think this should remain open.

    My Add-ons are still not working. May try to do a backup of bookmarks, passwords, etc. and do a full uninstall and install.

    EDIT: A full uninstall and clean install seems to have worked.

    There's an update to that article and in order to get the update you have to allow "studies" to run in order to receive the fix. This is under Tools - Options - Privacy & Security and scroll down to the section entitled "Firefox Data Collection and Use". I had everything disabled there but that will prevent the fix from coming through. I've temporarily enabled it and will leave it like that for a few hours to see if the fix arrives.

    Once I made that change the fix came through right away. All of my add-ons are back and running correctly.

    I went back and unchecked those options to run "studies" again.
