On the screenshots you can see my wallpaper and desktop icons peeking through. This problem had started like a month ago and it was just a one time thing, after opening the browser and getting fullscreen the 2nd it never came back until restarting the browser. Now after the updated with rounded edges everywhere, going fullscreen is always misaligned

I don't want AI I don't even want to be near it. I don't want it lurking in the background of my browser. I don't want to waste a single processing cycle on even considering it. I never wanted AI, and they jammed it into my browser.

Currently, they popped up an ad for "AI Enhanced Tab grouping" and said that you can turn it off in the settings. I looked in the settings, and could not find such a thing. Searching for "Tabs" "Suggested" "AI" and other such related terms yields no AI things.

Why tell me I can turn something off in the settings if there is no setting to turn it off?

But that's just the start.

I want nothing to do with AI. I don't want to use a browser that supports it.

I WILL MAKE MY OWN DAMN BROWSER IF I HAVE TO. I QUIT GOOGLE, I'LL QUIT FIREFOX.

Mozilla used to be a safe-haven from all the bullshit other tech companies were pulling. And now this.

GET. AI. OUT. OF. MY. BROWSER.

I DON'T CARE IF IT'S LOCAL. I DON'T CARE IF YOU SAY IT'S SECURE. I DON'T CARE IF IT'S GETTING BETTER. I. DO. NOT. CARE.

GIVE ME THE OPTION TO PURGE AI FROM MY BROWSER OR BY FUCK I'LL FIND A NEW BROWSER.

What the title says. At some point Firefox wanted to update to a newer version, it asked me if I wanted to refresh it, I said yes, nothing much happened besides I got a brand new folder I can't remove from my desktop. It asks for admin rights, I have admin rights, it's a local account, I am the only user, I tried the command prompt solution and it didn't help. Is there any solution to this at all that doesn't involve me getting into the bios?

I have my desktop extended across two displays. If I disable Hardware Acceleration in Firefox, entering fullscreen causes the window to be slightly offset down and right, leaving a thin band on the top and left sides of the screen where the desktop background and taskbar are visible behind the Firefox window.

From testing I have determined that this issue does not occur if I only have one monitor enabled or the monitors are mirroring the same display. I have also determined that the issue only occurs when Hardware Acceleration is disabled.

I got the new FF update this morning and noticed shortly after when i got back online a bd_config.cfg file popped up onto my desktop windows 10. I deleted it not thinking anything about it and when back online again and it popped up again in fact everytime i did this it popped up no matter what i did and went online.

It has something to do with BitDefender i figured out uninstalled bit defender re installed it no luck

Refreshed\Reset Firefox with no luck either.

This is both a settings issue, and a privacy and security issue. I want to disable the google lens context menu item to protect my security and privacy from constant AI monitoring. I've almost accidentally clicked the new option before and I don't want to send photos or images to google's AI unless I specifically intend to do so.

I feel like Mozilla is interfering with people's privacy more and more, taking away features from their users, adding features we don't want, butting in and telling us how our browsers should work. This is starting to become absurd. Now you've added AI into the browser that can control how your tabs are displayed and named even, a setting I found while trying to disable Google Lens.

There's a couple other settings I need to figure out how to disable too, such as the context menu of translate and the ChatGPT context menu items. I just removed ChatGPT and a new AI chat bot option appeared. Just wow. What the hell Mozilla. Is your intention to just turn your browser into one big spyware?

Give me the option to disable all of this stuff you keep adding. I have a policy thats supposed to disable your auto updates too but YOU disabled that as well allowing you to install all this malware/spyware into my machine without my authorization.

Hello,

In the latest update I got it made everything into rounded corners. The Tabs and Settings windows as an example. How do I undo that?

I checked thoroughly in the appearance settings and dont see a way to do that. I specifically switched my entire world over to Firefox to get out of the rounded corner UI world only in time for this switch to happen. How do i undo it?

I have various shortcuts saved on the shortcut page comes up after logging in. Its set to 2 rows.. I use it every day. Used it this morning and working perfectly. Been out and when I came back the page is totally blank. I've tried sytem restore to 5th October but makes no difference. I use Windows 10 and read that Firefox are continuing to support Windows 10 I'm visually impaired and use a desktop PC with a large screen. I'm not PC techically knowledgeable. How do I restore my shortcuts or how do I re create them?

Youtube does not work. It shows somekind of default page that is essentially blank. It does say: "Try searching to get started" and "Start watching videos to help us build a feed of videos you'll love."

But it will not respond when I attempt to search anything.

Hello Mozilla Support Team,

from yesterday playback speed on youtube is not working. When I open the same video with Edge playback speed is available.

Could you please check and rework?

Thanks in advance.

Many greetings Stefan

Is there a way to backup a profile?

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.

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

A week ago I got a BSOD that ruined settings of most of my extensions and most likely some of Firefox's settings too (at least it erased my custom findbar.matchdiacritics value, but probably not just that). After that I moved Firefox's folder and re-installed it. I also created a new profile. The 2 profiles are synced. Because of that, the new profile got (almost) all the extensions from the old one automatically. Then, I decided to do a clean install of those extensions (the reason why is a story for another ticket). So, while both profiles were opened, I removed one extension in the new profile, waited for a bit and checked the old one to see if it got removed from there too. At first it wasn't, so I thought they are not synced (anymore). Yeah, sure, but once I removed all extensions from the new one, the old one woke up and removed all extensions from there too. Great! Awesome! Loved it wholeheartedly! It really had to wait until I removed them all, didn't it? Anyway, I had a backup of my old profile, so I restored my extensions and their settings on both profiles eventually. So now I have clean installs of Firefox and extensions. Back to the issue. I can't load Steam pages (at least store.steampowered and steamcommunity) normally anymore. They load forever, and if the blue dot eventually stops moving (after an insane amount of time), it's either a plain white screen, or badly loaded page with most images missing.

• Edge loads them just fine
• Steam client loads them just fine.
• If I turn on VPN plugin (I use Browsec), then it works. It's like that in both old and new profile. That's why I mentioned that funny little story before.
• Tried Troubleshoot Mode, didn't help.
• Tried to selectively disable some extensions, same.
• Obviously tried to remove cookies, Ctrl + F5 and whatnot. Btw, if I clean everything and try to load it, then it's (most likely?) a white page, but if I turn the VPN on and load it first, and then turn it off and reload it, then it will look a bit better, but still will load forever with some media missing. (Which kinda make sense since something was already cached.)
• Tried to change proxy settings from “Use system proxy settings” to “No proxy” and “Auto-detect proxy settings for this network”, nah-ah.
• Tried to disable DNS in Firefox's settings, no siree.
• The console throws different warning and errors every time (that are probably even unrelated). Or none at all.
• Probably tried something I already forgot about.

Also, it seems the culprit is actually Akamai (it's where the Steam stores its media) or whatever is preventing reaching it. Because it often shows something like “Waiting for community.akamai.steamstatic.com...” in the status bar for a long time. It seems like the problem is within Firefox's settings, and it also looks like settings aren't synced across profiles (or at least some aren't, I definitely had to configure them on the new profile manually). Anyway, I am out of ideas and my butthurt thrust is about to deliver me to Uranus. Thanks for your attention!
