Diễn đàn hỗ trợ Firefox

First the browser did not work. When extensions were disabled it worked. Now the 1 password extension does not work, only if I create a new profile in firefox. I do not want another profile, is there a solution? I also use Add blocker extension. Pages sometimes do not load at all.

I used a number of extensions for years. I recently updated Firefox. Now, I don't see any of my previously installed extensions listed. What happened to them? Are they just "hiding" someplace or are they gone?

Hey!

Anyone has any ideas why the extensions does not work properly anymore? Or is in similar situation?

My browser has been updated, as well mentioned extensions (its only 4 of them really). They worked fine for years and now suddenly - when I click on them - there is no response! I refreshed and re-installed the browser as well. Restarting does not help either.

I kept my installation of Windows 11 while doing a clean install of Windows 11 to another drive. I installed FF and copied the profile from the old installation to the new one. about:addons displays all my add-ons and they're all enabled. But their icons don't appear to the right of the search bar. How do I get them back?

every website i go to says I have AdBlock Plus enabled as an extension, ad-on or whatever. I can not find it anywhere in the extensions menu, add-ons manager, etc. to turn it off... I have looked in every folder and area that I can, looked through my entire account info, profile, security, extensions, plug-ins, etc. Can you please help me find it so I can turn it off, uninstall etc.

Thank you for your help!

I found a problem with McAfee Webadvisor 13 Aug 2025 release. It causes flickering in the upper right part of the screen. Disabling it in Extensions fixes the problem. Removing it and reinstalling causes the problem to reoccur. This is new, had no problems yesterday but today all four of my family's computers have this problem. I will report the problem to McAfee and give an update if I get a response.

The moment my version of Firefox auto-updated to 141.0.2 (64-bit), all of my extensions disabled. There is no option to re-enable them and no indicator of why they are disabled.

I found that switching to a new profile allows them to work, but of course that's not really an option; I have huge amounts of custom stuff in eg. Greasemonkey that I cannot afford to lose.

What can I do to preserve my extensions without losing things like Greasemonkey scripts? Again, deleting them and reinstalling them is not an option if it would lose their individual configurations.

One of if not my most favorite addon "context search" has recently been flagged as violating mozillas tos. I'm talking about this one: https://addons.mozilla.org/de/firefox/addon/contextsearch

I am unable to find further explanation or the exact reason for this decision, but I am able to activate it again at my own risk. Seeing as I don't know what the problem is, I am hesitant to do so. Could someone explain what the issue is and if it's safe to continue using that addon? Am I or is my personal information at risk, since I have been using the addon regularly?

Whenever I try to log into my Eset Password Manager it says unable to log in offline. Yet Eset password manager works on other browsers. I have refresh the browser and removed and re add the Eset extension.

I just approved an upgrade to Firefox that mentioned something about a new way of dealing with extensions. The first thing I noticed was my 1Password add-on in the toobar disappeared. I took the steps recommended by 1Password to add it back, and I can get a 1Password icon to appear on the toolbar, but it is non-functional. I confirmed 1Password is still functional with an icon in the toolbars of my other browsers. What gives?
