Firefox Community Forum

I was trying to revert to an older version of Firefox. It asked me to create a new account to avoid data problems and junk. I clicked that, something went wrong, I ended up logging into my original account, and now all my bookmarks, add-ons, history, everything is gone, and there's nothing to sync anymore for some reason, even though it was working before. And the older Firefox I downloaded automatically updated to the newer version, so it was pointless. What do I do? Please help.

Edit: Nevermind, I figured it out. I was using the wrong Firefox profile for my account.

In a few previous updates, FF keeps messing around with the New Tab layout, ruining its previous good look. I learned to revert it back to its former setting by disabling browser.newtabpage.activity-stream.newtabLayouts.variant-a and also browser.newtabpage.activity-stream.newtabLayouts.variant-b in about:config.

Now in Firefox 141, browser.newtabpage.activity-stream.newtabLayouts.variant-a has completely disappeared, no more allowing the poor user to get the look he wants.

Why? Am I missing something? What is the use of making the product worse or less user friendly?

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

Hello, I received an email from you asking me to change my Firefox password for account security reasons. When I changed it, all the data synced in Firefox with my email was deleted. This upset me greatly because I lost important data and saved websites. Please restore the deleted data. Thank you.

Hello, since I installed the Firefox 141.0 update today, I can't login to Reddit. I tried logging into Reddit right after updating Firefox, so did a System Restore to see if that corrected the problem, and it did.

To double check, I installed the Firefox 141.0 update again, and encountered the same problem logging into Reddit again, so it's definitely this new update causing the problem.

I've attached the Reddit messages I get. The 1st is the initial message, and the 2nd after I retry logging in.

I would greatly appreciate help with this.

Thank you,

Michael T.

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.

Downloaded an update of firefox. Is this for real? A message box came up and said I would get a NEW version of firefox but all my things would be saved. Now I have two firefox versions. My old version has all my info and saved and/or chosen settings. HOWEVER the newer version is a new install without settings and WORSE it has GOOGLE as the browser?!?! Is DUCK DUCK GO gone to goOgle? If I wanted a shopping app I would use my GOOGLE account instead of Firefox. How do I fix this?

YouTube videos encoded at 60 frames per second are extremely choppy in Firefox only. Microsoft Edge plays the same videos perfectly.

I have deleted my profile and reinstalled Firefox, updated graphics driver to the latest version, and toggled hardware acceleration on and off. Nothing helps.

I keep having an issue on my desktop of every new tab I open crashing. I can access the homepage, but if I put anything into the search bar, the screen goes to "Gah. Your tab just crashed. We can help! Choose Restore This Tab to reload the page." And when I try to restore the page, it brings me back to that screen again. I couldn't even access Mozilla Support on my desktop to report this, I am on this site through my phone.

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.

I had to reset Firefox because of a hack to my FB account. I've recreated all of the icons I use but Gmail won't add since Google doesn't think my desktop is one of my devices. I can receive Gmail if I use Chrome. I've tried reaching Google by leaving messages @ the Freemont office in Seattle but thought maybe Mozilla had an answer. Thanks for listening.
