Firefox Community Forum

I am having a problem with Firefox. Some websites do not load correctly and certain extensions do not work as expected.

I have already tried restarting Firefox and checking my internet connection, but the issue still happens.

Please advise how to fix this problem. Thank you.

Since Firefox updated to version 148.0 it has broken my ability to download any extension and I get that Installation aborted message for any extension I try to download.

It also broke my ad blocker, ublock origin, when it updated to 148.0

Well, well, well. Latest Firefox update and what did you folks send along to take over my PC screen when I log-in? This: https://getadblock.com/en/update/latest/?f=f&version=6.31.1&u=68uu84zt49066849&bc=3072&rt=0

Clever, clever, clever aren't you folks?

1. I have NEVER downloaded "adblock" 2. "Adblock" cannot be found in the PROGRAMS listed on my PC, so no way to "uninstall" your uninvited, unwelcome, unneeded bit of buy-this-buy-this-buy-this angling. 3. "Adblock" cannot be found on a search of the registry. 3. What a pathetic approach, Firefoxers!

GET RID OF IT FROM SHOWING UP ON MY COMPUTER SCREEN WHEN I OPEN FIREFOX! NOW!

Hello!

I first installed Video Download Helper several weeks ago and it worked fine. However, since the update of 04 March, 2026, it no longer works with YouTube. (It does, however, still work with Instagram.) Having checked all of the settings (which I had/have not changed), I uninstalled it today and then re-installed it. This hasn't helped. With YouTube, the Downloader icon (pinned to toolbar) simply remains grey and does not show any videos when opened. I am using the latest, fully updated version of Firefox with Windows 10.

Can anyone help, please?

Many thanks,

Stuart.

Can you help me out, please?

To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier.

Could you please disable your browser's Firefox addons just for a minute, make a post and see if you are still seeing that message?

How do I disable the Firefox browser's addons?

Suddenly none of my cashback extensions will activate, I click them but they are still inactive when I check. I have tried disabling ad-blocking and resetting everything all-time as far as history, ache, etc. Has there been some recent change that I can make adjustments for? I would rather not use Chrome.

I use Norton Password Manager. I use Firefox most of the time as my main browser. I added the Firefox extension for Norton Password Manager when I got my new laptop, but it never does anything but hang when I try to utilize it. Today I finally turned off the extension and just ran the Password Manager as a new tab on the browser and had no problem with it running. However, it doesn't give me full use of the PM. (It does at least give me my passwords and user names, which the extension wasn't doing.) I keep notes with some of my passwords that are important to me. Using the PM on Firefox on this new laptop, I've found that none of the notes show up in the windows. Is there something I haven't turned off or on that's causing the problem I'm having? I use the PM on my iphone as well and have had no troubles with it. Thanks for any help. Sally 12/14/2025

I am on a Windows 11 machine. Lastpass extension for the Firefox browser does not maintain my vault data. I have to refresh each time I go into the browser. This just started a couple of days ago. Perhaps after installing a new Tmobile gateway? Ideas on how to address/fix?
