On 5/3/19 Firefox suddenly alerted me that it disabled all of my Add-ons stating that "These extensions do not meet current Firefox standards so they have been deactivated."

Immediately below this message, Firefox gives me the option to "Find a Replacement" Add-on.

After going through this process and locating the replacement Add-on, all attempts to download this (or any other Add-on) produce an error message stating "Download failed. Please check your connection."

However, my internet connection is working just fine.

I am running the latest version of Firefox (66.0.3 (64-bit)). And I have tried downloading the Add-on with my anti-virus temporarily disabled (with no success).

Screen captures are attached.

Does anyone know what is causing this issue and how to fix it?

Thanks in advance.

I got home, turned on the PC, loaded up Firefox, and ALL my addons are disabled and tossed into their 'legacy' pool of crap. No happy colorful theme, NO adblocker, no Ghostery... it even disabled my Bitdefender add-ons. Something is NOT right here. Anyone know what's going on? Firefox has NOT updated in at least a week or two, so I doubt it was an update breaking anything.

One main reason I am asking about this is because I have to download screenshots for a group I'm in and organise tables etc... For every photo added of games played, results etc... I don't get to see the relevant information I need to be able to download it.

I've tried uploading 2 pictures to here to show what I mean but they won't upload either even though they are under 1mb. Basically, when you click on any picture on facebook, you get a distorted version of that picture, or, there are no options available for downloading it etc.. When I access the same pictures on Chrome, I can like it, download it etc...and everything else is also listed, so I don't understand how Firefox isn't showing any of it.

As both browsers are on this same computer, both upto date etc..., does anyone have any idea why Firefox isn't showing everything ?

Your help would be appreciated immensely as this really is doing my head in :(

The Messenger page cycles and then goes blank, but with the full top-menu items showing.

When I try the Notifications pull-down it just cycles, and never shows the notifications.

These two FB features work perfectly on Safari.

Is this a Firefox problem, or a FB problem?

I never trust, download or install anything related to Russia or China, I don't want those spies get control of my PC. After many years of using FF, I just found something that shocked me: Baidu Search Update Extension What's this installed with FF installation? Note: I never run Firefox.setup.exe but just extract it using winrar, from "core\browser" remove "features" folder completely then install it. Where can I remove it from install source? Anything related to those Chinese search engines?

Anyone know of a hack that will turn these off? Other threads on the subject have been turned off, with no real solution. Thank you.

I have Windows Firefox 66.03.

Enabled Studies, and had "hotfix-reset-xpi-verification-timestamp-1548973" in "active" status. But I didn't have the second study! Nothing happened for few hours! So I tried to disable Studies and enable them again. After that the first Study became "completed" and no "active". The second is still absent. What should I do?? How to get the required Study and fix the problem? Can you help me please??

This morning Adblock Plus was disabled in my browser.

the message n the EXTENSIONS PAGE reads: "Adblock Plus - free ad blocker could not be verified for use in Firefox and has been disabled".

I've been Adblock PLus using for years, on both my computers. And it still functions on my Windows 10 desktop. Is this because it is Windows XP? Can I do anything to reacivate it?

I tried to add Adblock Plus again on the computer - but that did not work either. I get a message that says: "Download failed. Please check your connection' - but I am using the connection without problems everywhere else!

I'm a premium member at Bill O'Reillys and receive no spin news to view. I use to be able to view the no spin news up until approximately 7 weeks ago. I can no longer view the no spin news and I haven't got a clue as to why. I am not tech savvy and I have spent many hours trying to locate the problem unsuccessfully.

After signing into my account to view the video it gives me hlsjs:video file not found. I am able to view the video of the day but not the no spin news. I tried google chrome and Internet explorer and it says the same thing, video file not found. I'm sure there is someone that has the solution to my issue. Help and thank you.

Just today Mozilla suddenly reported that several of my extensions where outdated and had been disabled. When I checked the 'legacy extension list' is showed every single extension as being unsigned, the list includes:

Add Block Plus IDM Integration module Malwarebytes browser extension

I have gone to the add on page and tried to install (or re-install) the latest version of each of these and it fails with the error "Download failed. Please check your connection." As I know my network connection is good, this is clearly bogus. So far all I have done otherwise is run a full virus scan with malwarebytes (and got nothing) and reboot just in case. Some searches on the web have turned up installation failures like i am getting, but most of them where a year ago or more and specific to a given add on. I haven't found anything on mass disabling all extensions.

Currently running version 66.0.3 (64 bit) of mozilla.

Thanks for any help you can provide, Eric Hough

Ever since updating to Firefox v 66, the browser won't load webpages until I disable ublock origin in the add-ins page. It's very repeatable, I disable ublock and the page loads. Enable it again, and new pages won't load. I've also disabled all my other add-ins when doing this, so it's not some weird interaction between add-ins.

Normally I would consider this a ublock problem, but it didn't change. This started happening with the Firefox v 66 update. I've searched, but nobody else seems to have the same problem. What can I try (besides getting rid of ublock)?

When I am using firefox, it crashes 30-40 times a day. I think my drivers are up to date. It is driving me crazy because I use my computer basically all day. Is there a software that it does not work well with? I am wondering if that is the problem. Thanks!

I tried your solution to update the certificate, but it did not work.

Note, I could not figure out where to check the certificate was updated (as you posted in the screen capture of image #2).

The first step seemed to work (clicking on your link and clicking OK on the popup to download the certificate).

The RESET of the lastupdate value also seemed to work, and after restarting Firefox it now shows VALUE of 1557118303.

But the adblcok plus stll not working.

Note, I tried to download the certificate using step 1 again, and that time an ALERT said CERTIFACATE ALREADY INSTALLED...

What can I do now?


+++++++++++++++

FYI: Your instruction in the OTHER THREAD was:


Hi Matt, I was able to start testing in Firefox 52 ESR. When I install the hotfix extension, nothing happens, other than showing up on the Extensions panel of the Add-ons page. In the Browser Console, I see this message: TypeError: browser.experiments is undefined That means the main command of the extension doesn't run, so it's a dead end.

Next idea:

Overview

(1) Install the certificate the hotfix would have installed (2) Trigger Firefox to re-verify your extensions (3) Wait until it is back to normal

Steps

(1) Install certificate

I extracted the certificate from my Firefox 66 and saved it on my webserver. Obviously if you don't trust me, you should not install it.

Two possible methods: click to download through the certificate installer, or right-click > Save Link As to save a local copy and then import it.

https://www.jeffersonscher.com/sumo/signingca1addonsmozillaorg_20190504.crt

Screenshot #1 shows the download method. Don't check any of the boxes, just click OK.

To import instead:

Go to the Options/Preferences page, Advanced section, Certificates panel, then click Certificate Manager. Make sure the Authorities tab is selected, then click Import. Find the file you downloaded and open it, then you should get the same dialog as in Screenshot #1, don't check any of the boxes, just click OK. Then you should see the new cert in the list in the Certificate Manager, as shown in Screenshot #2.

(2) Clear the time Firefox last re-verified

This will set Firefox up to check much sooner than it otherwise would check.

(A) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.

(B) In the search box above the list, type or paste xpi- and pause while the list is filtered

(C) Right-click the app.update.lastUpdateTime.xpi-signature-verification preference and click Reset on the context menu

Screenshot #3 illustrates the expected result.

(3) Restart Firefox

You can exit Firefox normally, then start it up again. In my tests, it took less than 60 seconds for Firefox to verify my extensions. Screenshot #4 is "before" and Screenshot #5 is "after."

Hopefully that will work for you.

I don't like MSExplorer or Bing. I've set Firefox Quantum 66.0.2 (64bit) as my default browser with search results from Google.

When I type a search in the 'Type here to search' window, MS Explorer opens with a Bing search result.

How do I get the thing to stop opening Explorer and simply open FF?

And again, Firefox is absolutely set as my default (menu/options/'smiley' Firefox is currently your default browser)
