While using an opened tab which I want to keep in place, I find it frustrating that if I want to click on one of my bookmarks in my toolbar, it uses the tab I am currently in which, of course disappears and is overridden with my selection of a bookmark. Is there a setting for me to change how my choosing of a bookmark reacts? I want it to open in a new tab and not on the one I am working with. I have looked everywhere and I cannot find a setting for this.

Roughly every 2 weeks I backup important files to a external hard drive.

One of the things I always backup is my Firefox profile. I have been doing this for years without any problems.

I 7zip my profile and copy it to the hard drive.

I tried to do this yesterday (July 25 2025), and was getting access denied messages for files in the profile. So I tried to simply copy the profile. Same thing access denied.

I cleared the history, used wise disk cleaner, rebooted my machine and tried again. Same thing access denied when trying to backup or copy the profile.

I am assuming that this is happening since 141 because I updated Firefox since the last time I backed up my profile, and never had a problem previously.

Could anyone have an idea what the problem is? Thank you for your time.

I just updated to the latest version of Firefox, and all of a sudden I have a new icon, Extensions, that looks like a puzzle piece, I cant seem to be able to remove it....at all.

I have lost all of my bookmarks, bookmark tool bar after Firefox's last update. I have spent the last day trying to recover what has been lost but I am having no luck in getting everything back in place. I have tirelessly gone over all your possible remedies and get no results. I can't even send a message to Mozilla through their help messaging system. My only recourse appears to start using another web browser. If I can't talk to someone who can help guide me through a mess I did not cause, then I am forced to find another company that is responsive to my problems. Call me at [edited] or write me at [edited] if you want to keep me as a user of your service. Regards Mark Hannah

I am very disappointed to learn that Firefox is moving forward with AI integration. I use this browser specifically because there is no AI. AI tools are a drain on public resources such as clean water and electricity, and the data centers that host the AI servers are a burden in many ways on the communities where they're built.

Additionally, I am concerned that the AI will turn all of our browser history into an AI slop ad factory where our data is more easily collected and sent off to generate more ads.

If AI is integrated into FireFox, I will no longer use this browser, even if the AI can be "turned off".

Is there any way to keep AI out of FireFox?

On my Windows 11 computer messages keep cropping up supportably from Firefox. I have switched the computer off. this is from my old computer. I don't know what to do now. Colin

I'm using Firefox 129.01 (64-bit), trying to log in to my Tufts Health Plan account, and get a security warning (screen shot attached). Customer Service at Tufts Health Plan tells me that I should use Chrome.

Should I ignore the Warning and proceed?

I had a lot of tabs open in Firefox, and they always stayed there even after restarting my PC. But suddenly, all of my tabs disappeared, and I can’t recover them using “Recently Closed Tabs.” Can I get them back?

Suddenly I cannot search from the search bar. It defaults to the address bar. why "fix" something that was not broken. Being forced to use the address bar is frustrating. If you go directly to the address bar, it tells you it cannot find that site.

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

Recently, after the newest Windows 11 update, Twitch hasn't been loading correctly, the tab looks as if it finished loading, but the page gets stuck in endless loading, no other site has this problem, and it happens even opening links to Twitch channels directly. I've added and screenshot of the problem.

I'd love some help or at least know if this is a problem on Twitches end or not. Thanks.

Today I realized that I have installed two (2) versions of Mozilla Firefox on my Laptop PC which I rarely use.

Both editions are 64-bit type but one is version 109.0.1 (11/04/2023) in

C:\Program Files\Mozilla Firefox and the other is version 128.0.3 (28/07/2024) in C:\Program Files (x86)/Mozilla Firefox.

I suppose it is illegal to have two versions of the same App., so the question is how can I delete the old version (109.0.1) without affecting or damaging the new version (128.0.3)?

Thank you, JOHN HATZITOLIOS

I just started having an issue while watching Live Streams on Youtube with FireFox. I'll load the live stream and it will run for about a minute then it will switch to the streamers previous recorded stream. I opened Youtube on my iPad and on Edge browser and the Live stream keeps playing the live stream but on FireFox it only lets it run for about a minute before flipping the playback to the previous recorded video of that streamer. I tried clearing my cache for Youtube and I have no extensions running. I have Youtube Premium and run no adblockers. I have also tried safe mode but the problem persists.

Any idea what could be happening?

.: Hello. A couple of days ago Firefox stopped displaying thumbnails of YouTube videos. I tried YouTube on other browsers and the thumbnails appeared as usual. On Firefox, they've disappeared, but only on my Windows 10 computer. The YouTube thumbnails appear on Firefox on my MacBook. The attached graphic shows what it looks like on my Win 10 computer.

Any ideas on how to solve this would be greatly appreciated. I have also searched the Internet and YouTube for a solution, but was unable to find one that works.

Thank you.
