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.

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?

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 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?

Hi everyone Since sep-15, The "Open previous windows and tabs" function is NOT working .. everytime i have to reopen all the previous tabs. I am not sure if any update has caused this. Please help. Thanks

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.

Just noticed that Firefox only has translation for Chinese Simplified from Mainland China, but no Chinese Traditional from Hong Kong and Taiwan users. Any plans to get it going? I would hate to switch back to Chrome or Edge instead.

I have clear search history when browser is closed checked, and it still has a months worth of history and I have closed and reopened the browser countless times, why doesn't the history clear?

The favicons on my homepage are not appearing when I launch Firefox, and I can't find any way to restore them. Turning the favicons on/off in the settings doesn't help, it just moves the location of the search bar. I've included some images to better illustrate the problem.

Is there any way we can restore the favicons?

I switched to Firefox a few months ago and I've been using the "about:profiles" page to mimic chrome's profile feature. I have 3 profiles, each with their own Mozilla account. How can I migrate these to the new profiles system?

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.

Hello Firefox Support,

Since the latest update of the Firefox browser, I have been experiencing frequent freezes. The browser becomes unresponsive when performing basic actions such as:

• Clicking on the menu

• Closing tabs

• Copying or editing the URL

When this happens, the only way to recover is to close Firefox and reopen it.

Could you please advise on how to resolve this issue?

Thank you for your support.

Best regards, Mohamed Adel

Windows 10, latest version.

I hit a shortcut, I think, and heard the trackpad, then one of the three open tabs was isolated from the rest in a separate, almost chromeless window.

It's not in the taskbar pop-ups but instead has its own icon. In this 'chromeless' window there is no option to add a tab or window, there is no area to move it (I have to carefully use emtpy space in between buttons to move it). The top just fell off, that's basically it.

I have never seen this and have been using Firefox from the start way back when. I didn't install anything; this just happened as I was reading something and accidentally touched a key. Nothing changed, no settings were adjusted, nothing.

This option is not in the tabs menu or anywhere. I must say I kinda like it for this one 'tab' (which is a solo chromeless window) but I do need the menu and so on for productivity.

One of the screenshots shows this 'window', the other shows that 'window' is not part of the regular pop-up tabs in the taskbar but rather has its own icon, as if it were an app, in that taskbar.

What in the world is this? Can someone help?

Issue remains - see post [https://support.mozilla.org/en-US/que.../1525355]

Is there a way to backup a profile?

Hello- When I am on a website and click link I would expect and want a new Tab to open-- I want it to open it in a new Tab and leave the page I'm on alone so I can go back to the original page.

Instead, Firefox overwrites that page and the tab with the a new one, and I have to hit the back button to get back to that original page. And most often the back arrow button is grayed out and I can't get back at all.

In settings, I've tried checking the box for: 'Open links in tabs instead of new windows' but that doesn't do it. I've also tried checking the box, 'When you open a link in a new tab, switch to it immediately,' and that doesn't do it either.

I know that a work-around is to hold down the Ctrl key while clicking a link, but I'd like to set it as a default so I don't have to do that. That's a pain and not a natural function when browsing. To be sure, I want to click on links and that creates a new Tab without Ctrl Keys.

Thanks!
