Dear Firefox Support Team,

My Mozilla Account was Accidentally Deleted Today and I'm Looking to Recover my Data (History / Passwords / etc.). Is There any Way to Do so?

Thanks in Advance

For a couple of days now my cookies have been getting deleted or corrupted every time I turn off and back on my computer. The only temporary solution I've found have been to delete my cookies.sqlite file, copy cookies.sqlite.bak and renaming it to cookies.sqlite. It is very frustrating to lose all my extensions, my cookies, my bookmarks and logins to my usual websites. I am using Firefox version 146.0.1, on a Windows 11 computer running version 25H2. Also, my original cookies.sqlite file is 512kb while my backup is 2048kb exactly, if that is useful in any way. How can I fix my issue?

If I check "Always ask you where to save files" to true, the settings is reset to "false" after I restart my browser. Is this a bug? How can I make this setting persistent?

I use Firefox 146.0.1 (64-bit) for Windows 11

How do I copy files such as the 'bookmarkbackups' files from the Profiles folder?

As seen in the prtscr I get an error message when I try to copy any file from Profiles folder. Firefox is closed and I am admin and trying to copy the file as an adminstrator.

Asseeninthe subject line and here, the space key often does not result in a single space being displayed although sometimes -- like just now -- it is termporarily starting to work.

I am running FirefoxVersion 146.0.1 (64-bit)onWin11(andgetting erratic spaces and backspaces again.)

Interestingly, the main Enter key also has similar problems although the keypad Enter key seldom does.

TheDeletekeyhasneverhad this kind of problem so I haveoften used back-arrow and Delete instead of Backspace.

Tobefair,thisalsohappenswithNotepad++ and other programs.

I have no idea how to troubleshoot such an erratic/intermittent situation.

I lost my Firefox on my pc. I thought i needed to download it again but when I downloaded it, it was a different version and none of my bookmarks were available. I don't know how to restore my old firefox. Help, please.

Issue Summary: My website (mass-doc.com) displays blank thumbnails in Firefox's New Tab "Recent Activity" section, while other websites (Claude.ai, Ahrefs, FamilySearch, Fox News, Xfinity) display their OG images correctly in the same section. Environment: Extensions Installed: uBlock Origin, FireShot (both tested disabled with no change)

Evidence That OG Images Are Correctly Configured:

Google Search Console "Insights" section correctly displays my OG images Social media preview tools show images correctly Images load directly when URL is accessed in browser Image specifications meet requirements: 1200×675 pixels, 132KB file size, JPEG format

Example OG Meta Tags (verified correct):

Hi. I just switched to Windows Defender for antivirus. On Google Chrome I had to add an extension so Defender will work with Chrome to detect malicious websites.

On the eicar.org website the test virus is stopped on the Microsoft and Chrome browsers, but not with Firefox.

How do I set up Defender to work with Firefox?

Thanks

My SSD boot drive crashed -- Rebuilt system (brand new SSD boot drive) and reloaded all of my data from a separate backup, however Firefox profile is gone. I have copies of the old profiles including the places files, etc. Following Mozilla's instructions I reloaded the old profiles. Firefox starts right up but *without* my bookmarks, etc. Unfortunately there was no "old Firefox data" folder saved and I could not retrieve the bookmark specific backup. Thoughts? Thanks!

使用系统：win11。我在之前的Firefox上已经登录了账号并开启了自动同步，前天我重新安装了系统并下载登录了账号。登录了账号之后并没有重新同步我的书签，我手动同步多次没有结果，并等待了一段时间自动同步，以及观察是否会同步书签到本地，结果仍没有。于是我尝试用我手机的Firefox登录电脑的Firefox，结果才同步了我手机的书签信息，但我手机的书签信息已经过时。而且电脑的Firefox显示可以和手机的Firefox互相同步信息及标签页等，但我观察后发现并没有完全同步，我电脑/手机的信息及标签页都是一天两天之前的，手动同步后仍然没有看到有更新。我希望同步回服务器的书签信息！

We have a question about bookmarks sync, with specific characteristics, please.

We purchased another computer, a laptop, and wish to benefit from the bookmarks sync between them. However, we're affraid of a backward syncing situation. How can we make sure we prevent that?

For example, say we worked on the desktop for a week, and then need to use the laptop. What should we do when we turn the laptop on and open ff browser, if we wish to sync from the desktop to the laptop? Do we press the Sync button on the laptop? - or will that force a backward synching from the laptop to the desktop? If that's the case, than how do we sync reliabely? And let's say the day after, from the now-updated-laptop to the desktop? Is the safest way to do it by turning the sync option off, and copying the bookmarkbackup folder from one updated computer to the other?

Also, this may complicate things a bit - We use the browser bookmarks in a non traditional way. It's kind of an archive for us. The .jsonlz4 file size in bookmarkbackups folder is 37MB. We remember reading somewhere before, the server backups stores files up to 10MB. So, question is, does the large size or the bookmarks file will affect the synching process between computers?

Thank you very much! :)

why everytime i open i new tab it appears in my shortcuts section i only pinned like two sites and evry time i open a new page it appears in the shortcuts and theres no setting that i can turn off

In my Firefox browser, when i try to sign in to Youtube, a window says "there was an issue signing in to Youtube" pops up. None of the troubleshooting articles are helpful for my situation. My Firefox browser is up to the latest update - version 146 on windows 11. Youtube works, but i am prevented from signing in to my account.

I have used Youtube in Firefox before by signing in to my google account, the only thing that has changed was that I went into settings and cleared my browsing history, cache, and cookies. Once those were cleared, Youtube won't sign me in and only shows that error window.

In my Firefox browser settings, I have set Youtube to accept cookies and have disabled adblock for Youtube.

My Youtube account is still accessible using Chrome, but not in Firefox. Youtube WILL sign me in if i use Firefox private browsing. I'd rather not use chrome since Firefox is my primary browser and I'd rather not jump through the extra steps of google sign-in using private browsing.

I do have a Google account with my school institution, but that has never been an issue (expect it won't open google maps for some reason, not the issue here though). My Youtube has always been signed in with my personal Gmail, not my school Gmail. I'm not sure if that's interfering with anything.

To reinstate the main issue: I cleared my browsing data and cookies, now Youtube in Firefox won't sign me in.

Hello, today I have set up a new account for work and I have trouble signing in. Actually, I manage to sign in, however I am then shown the screen which gives me the option to create account recovery key and the browser freezes completely. I am unable to click on anything, the only option is to go to the Task Manager and kill the program there. Then, when I open Firefox again, I am not signed in (even thought I recieve the email about a new sign-in to mozilla) and have to try the process again, only to experience the freezing browser again. How can I solve this or troubleshoot? I have Win11, my broser is supposedly up-to-date. Thank you! Anna
