There are many tabs open in the firefox window. I'm closing the firefox. I'm opening it again.All tabs opened during the previous opening disappear.Either a new page or a single tab opens. The settings are set to "Open previous windows and tabs" (Image 1)

I go to "Firefox View" ---"Open tabs". (image 2) I see 2-5 windows there.In this case, there are 3 windows.WINDOW 1 is my main window with the tabs that should have been saved and opened when firefox was launched again. I close all tabs from unnecessary windows with a cross.Only window 1 remains. But when restarting, an empty or different window opens again.And again, there are a lot of unnecessary and incomprehensible windows on the list. Previously, a window with restored tabs from the previous session always opened. Question: 1)How can I restore the normal recovery of the previous session when restarting? 2) Tell me.I can somehow switch between windows (Firefox View" ---"Open tabs)(Image 1) Thank you.

When trying to install Firefox 141 on a Win11 computer with no internet access the installer starts going then there is a error pop up saying this version of firefox requires Win10. Is there something that needs done to work around this?

I kept my installation of Windows 11 while doing a clean install of Windows 11 to another drive. I installed FF and copied the profile from the old installation to the new one. about:addons displays all my add-ons and they're all enabled. But their icons don't appear to the right of the search bar. How do I get them back?

Hello! I saw that the Test day event had started. In Firefox Beta, I entered messaging-system-action.testday in about:config, put it on a string and set the value to testday as it said in the instructions. When I restarted Firefox, the welcome window did not appear and there was also no letter S next to the search as it should be. Please help!

Thanks for the answers!

My wife's Firefox was triggered from an e-mail link and in the process got updated to release 141.0 The result is that the tabs from the previous verion have not loaded. Can I still recover them?

Ever since the latest update to version 141, YouTube video pages only load like 3 quarters of the way. When I refresh it, I get the video. It's not an adblocker problem, because I turned off all my adblockers and tried YouTube and had the exact same problem. It loads the home page and subscriptions and other stuff just fine, it's only video pages that have the problem. Is anyone else having this problem or is it just me?

Windows 11 update KB5062660 causes Firefox browser to crash immediately after startup 设备名称 702-wenjian 处理器 11th Gen Intel(R) Core(TM) i5-11400 @ 2.60GHz 2.59 GHz 机带 RAM 16.0 GB (15.7 GB 可用) 设备 ID 1FE25F14-B045-48BB-BA31-A842A8B33888 产品 ID 00330-80000-00000-AA679 系统类型 64 位操作系统, 基于 x64 的处理器 笔和触控 没有可用于此显示器的笔或触控输入

2025.07.23 I have installed the update. https://support.microsoft.com/en-us/topic/july-22-2025-kb5062660-os-build-26100-4770-preview-9c5bc200-52b6-4c1a-be70-80df6bbfe9c3 Then the browser cannot start. It manifests as the browser freezing within 3 seconds after startup, showing no response, and then having to choose to exit. I tried to downgrade version 137.0.2, but the problem still persists. After uninstalling this update, the problem was resolved.

I turned off my Windows 11 PC a few hours ago. Prior to turning the PC off,all was working very well as it has done since inception 12 months ago. When I turned PC a bout an hour ago, I have noticed that all my bookmarks have disappeared as well as my Toolbar and all items that were on the Toolbar. In addition attempts to "save" new bookmarks are fruitless. I did a "refresh" on Firefox but there was no improvement. Latest version of Firefox was automatically uploaded by Firefox last night - whether that has caused the upset I do not know.

Additionally - when PC was operating properly prior to being turned off today, I was able to use "Snipping" tool which I can no longer use.

I really need help please. Ron

Firefox update loaded today. Now running v141.0 (64-bit) Firefox on a win11 laptop. I have an email account that I've used for over 25 years...most of those via Firefox. Today, after the update, I keep getting "Secure connection failed and Firefox did not connect" messages...sometimes when trying to open the web site; sometimes the web site opens and I can read a couple of emails and then the messages are blocked and I get the message "Secure connection failed and Firefox did not connect". I have notified my email service support of the full content of Firefox's message, but have not heard from them. I suspect something in the Firefox update is the culprit. Same VPN as I've been using for several months without issue until today.

I am facing this issue that When I am using google map on firefox on PC, change to street view by dropping a orange person mark. The map changes to satellite view by mouse scroll down a couple of times automatically. How can I avoid to changing? It doesn't happen on Chrome, Edge and even Brave.

My passwords are not showing up on my new computer even though I am signed in to Mozilla on both my old and new computers and have selected for passwords to be synced. Any help you can provide would be appreciated.

Hi everyone

I used Refresh Firefox option and it created "Old Firefox Data" folder on my desktop.

Awesome stuff. Sadly I cant get rid of it, here is why:

1. At first it said that the folder is used by another program and I cant delete it because of that. Cool, I decided to uninstall Firefox and make a clean install, so I have space to delete the folder too.

2. Long story short, it didnt work. I removed Firefox and tried to delete that folder, but wait for it, yeah I cant because I need permission from MYSELF. Awesome stuff.

3. I decided to use safe mode, so I used run command to run msconfig and I changed it to boot in to safe mode. But wait for it! YES! Its bugged and I cant login in safe mode, because pin is useless and it doesnt give me option to use password, so after hour of various things I got back to my normal mode via CMD commands. THANK YOU MICROSOFT.

4. So now Im stuck with the lovely "Old Firefox Data" folder, which cant be removed normally, neither in safe mode and wait for it! NEITHER WITH ADMIN CMD, not even the takeown /f "Old Firefox Data" /r command. THANK YOU MOZILLA!

So is there someone knowledgeable enough to help me to get rid of that folder pretty please? Like really a lot please.

I've messed around with the UI a bit and now the firefox tools, which used to be vertically stacked on top of each other with text next to them, are a horizontal row of icons at the bottom of the bar. See images for comparison. I've not found a way to get them back to how they were in settings, sidebar settings or about:config.

With latest Firefox Desktop 141.0 I found an odd behavior of pinned tabs which now are scrolling left and disappear from view site in a top tab bar.

• Is this a new feature or bug?
• Any setting to prevent them from scrolling?
• How to prevent this from happen?

For the past 2 months I've found it very difficult to sign into my Hotmail account using Firefox. Microsoft keep telling me to use a VPN or another device. I like answering emails on my computer because of its large screen. I've tried signing in about 2000 times now. Firefox told me they can't help me because I'm not a Mozilla subscriber even though they own Firefox. Microsoft told me it's Mozilla's problem. Can anyone help me please. John in the Philippines.

Hi ! as you can see in my screenshot, the buttons for the history and chatbot are not vertical but horizontal. Is it possible to restore the previous display with these buttons? I'm using firefox 141.0.

Thanks a lot! 😁
