Firefox is constantly removing safe extensions, re-approving them, then removing them again a couple days later. This is very frustrating, and is enough to make me permanently switch to Google Chrome, since they don't do this, and since I have to use that browser when Firefox messes with these extensions. I have been a stalwart Firefox user for years, but Firefox is pushing people like me away with this ridiculous behavior.

The best example is LastPass. Chrome seems to think it's perfectly safe, as it is not removing it. I use it and need it to be available for sites I need passwords for.

Unfortunately, however, Firefox regularly removes this essential extension and others, then, as I say, allows it again a day or two later, then removes it again.

Please, Firefox, figure this out! Otherwise, you're going to lose a lot of users and get a very bad reputation.

It’s possible that there is a problem with the file(s) that store the extensions registry.

Type about:support in the address bar and press enter.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder

Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.

Delete all extensions* files and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

After, restart Firefox.

See "Corrupt extension files"

+++++++++++++++++++++++++++ You may have to approve the updating once again.

It's still happening. I've tried this solutions a couple times now, but after a while, Firefox will again remove LastPass. As I said, it keeps working in Chrome just fine, but not Firefox. So frustrating.

Mozilla needs to fix how it interacts with this one plugin.

https://support.mozilla.org/en-US/kb/update-firefox-latest-version?cache=no Did you update Firefox to the latest version?

Version 96.0, first offered to Release channel users on January 11, 2022 Version 96.0.1, first offered to Release channel users on January 14, 2022


https://support.mozilla.org/en-US/questions/1359657#answer-1463359 and updated to 95.0. . . . I finally found where the plugin "Widevine Content Decryption Module provided by Google Inc." was not updating to the newest version of December 1, 2021. Ver #4.10.2391.0

cor-el; Make sure you have the latest Widevine version. You can toggle DRM off/on to see if that makes Firefox (re)load DRM components.

You can possibly check the XHR requests in the Browser Console if this doesn't work.

I keep Firefox updated, up to 97.0 now (32 bit).

Tried toggling DRM, nothing changed. I am getting errors in the console, including: this.window.gBrowserInit is undefined ext-browser.js:1102 Unchecked lastError value: Error: Could not establish connection. Receiving end does not exist. background.js:1 Unchecked lastError value: Error: Missing host permission for the tab

The "Missing host permission for the tab" comes up repeatedly.
