I made the mistake to following Mozilla's advice on why my tabs stopped coming back after I closed out, despite the fact that I had that selected in my settings. Now I'm stuck with an "Old Firefox Data" folder on my desktop and I can't remove it because I need administrator privileges -- but it's my personal PC. WTF

Hi

Lets say i have 100 tabs open in my session. I mistakenly open a new window with one tab. After closing this window and starting firefox again, it starts with this one tab, so i have lost all my previously opened tabs. Is there a way to get those back?

Thank you very much. Dimitris

I received this download from Firefox today, July 22, 2025: xRqj7qhl.html - Size: zero bytes - Kind: HTML text . I've never experienced this before. Is it legitimate? Thanks

See the image below, how do I prevent that black box showing up and showing anyone who uses my device my sensitive data? How is this not a common setting to be changed?

Very insecure and Horrible to have on by default. Recently switched to firefox from chrome because of security concerns but stuff like this is making me want to go back, because HOW IS THIS SAFE AND SECURE?!?!?!?

I've typed in passwords in boxes that arent really password boxes, and firefox has suggested my own password in plain sight like in the image below.

Strongly recommend firefox to not make this default and make it an accessible setting to disable because I've leaked my sensitive information to online calls because of this. This urgently needs to be addressed as a security concern. At least have a cogwheel button next to the black box to quickly disable this setting. Very very disappointed.

After Windows crashed, I installed a new system and logged into Firefox using my account. But all my history, passwords, bookmarks were erased. I also went to my phone and everything was gone. I didn't erase anything myself. Is there any way to restore the previous state of the account? Are there any backups on the Firefox Sync server?

I have been using ChatGPT for a few months with no problems on Firefox but today I am not able to enter any text in the text field where you communicate with Chat. However, I can turn on the microphone and then after speaking a command I can hit enter and it works. I can also switch to Chrome and it all works fine. I tried clearing my data and cash, rebooting computer but still isn't working. what's going on?

I switched my default search engine from Google to Bing. As you can see in the attached screenshot, it should be searching with Bing. But for some reason the search results are always Google. How do I fix this? I haven't refreshed Firefox yet. I was hoping to avoid that.

Hello,

Not sure if posted under the right section.

Recently started having an issue trying to sign in to Microsoft Outlook (formally Hotmail) Web. I don't recall any changes i made or updates.

When i try to sign in, it opens a new tab and takes me back to the sign in page. This just continues.

Tried using MS Edge and don't have the issue.

So far tried Safe Mode which disabled add-ons, which are currently Add Block plus, and New Tab Override and the issue remains. Not sure if i tried the refresh option but i think it removes the extensions which is not the end of the world.

Added a few images, one shows duplicate tabs, which will continue

Firefox version 140.0.4 (64-bit)

Any ideas whats going

Thanks

So when I open some websites such as the RimWorld wiki ( https://rimworldwiki.com ), whenever i scroll my gpu for firefox launches straight to 100% and becomes extremely laggy. I have no idea what is causing this. My friends and other browsers run it completely fine. I have tried troubleshoot mode, gotten rid of all my extensions and themes, removed all cookies and cache and nothing works. My drivers are all updated, and I have truly just given up. If anyone has any solutions I would be much obliged.

After update to 140.0.2, clicking on Firefox icon in the dock does nothing. The title bar says Firefox is active, but nothing shows on my screen. What changed? Did you reset something in my preferences?

I regularly use a website which intercepts command-option-up and command-option-down for its own navigation. This is a central part of my workflow with this website, and without it it becomes completely unusable.

After updating to Firefox 140.0.4, these shortcuts are now used by the browser to switch tabs. I have not found any way to configure this. Am I missing some obscure way to do this or is this just impossible?

I imagine this change was made to support vertical tabs, but I'm not using those, so the command-option-left and command-option-right shortcuts make more sense for my horizontal setup. (I don't use those shortcuts either, though- I use ctrl-tab and ctrl-shift-tab!)

After exporting bookmarks.html from Ffox on old computer, importing it to Ffox on the new one, all good, except that bookmarks toolbar shows on the imported list but doesn't display as toolbar.
