Hello Mozilla Support Team,

I hope you can assist me with an urgent issue. After reinstalling Windows on my PC, I lost access to my Firefox Sync data, which includes years of bookmarks, saved passwords, and browsing history.

Before formatting, I had been using Firefox Sync with my Firefox Account (sometimes signed in via Google). However, after reinstalling Windows and logging back into Firefox Sync, my data no longer appears. At one point, I saw my account showing activity from just before formatting, but now that is gone as well.

I am worried that my synced data might have been overwritten or lost during this process. Unfortunately, I do not have a local backup of my Firefox profile.

Could you please help me: - Verify if my Firefox Sync data is still stored on your servers. - Assist with recovering my synced data or advise on next steps I can take. - Provide any guidance on preventing data loss in the future.

Thank you very much for your help. I look forward to your response.

Best regards.

Hello, I'm experiencing an issue with tab groups in Firefox.

• I use multiple tab groups in my browser.
• Normally, if I close the browser (without manually saving the groups), Firefox restores everything exactly as it was when I reopen it including all my tab groups and their current tabs.
• However, if Firefox crashes while the groups are open, I run into a problem:

 * When I restart Firefox after the crash and try to open my tab groups, all the recent tabs are missing.
 * Instead of restoring the most recent state of the tab groups, Firefox loads an old, manually saved version from the past.
 * Any recent changes to the tab groups are completely lost.

This has happened multiple times now.

• • System Info:**

• Firefox version: 141.0 (64-bit)
• OS: Windows 11

I'd appreciate any help or suggestions to prevent this data loss after crashes. Is there a way to make Firefox auto save tab group states more frequently, or restore the most recent session even after a crash?

Since a few weeks I have been encountering an issue where tabs in Firefox would frequently crash. I do have various add-ons installed, however I haven't installed any new ones around the time the issue has been occurring. I've been unable to track down which add-on or if any add-on might be causing this.

Trying to search for this issue all I could come up with is that it might be an issue of a faulty CPU. I have an i9-13900KF which has been known to be part of the Intel generation with serious flaws. However I already installed a BIOS update and applied Intel's recommended settings to undervolt the CPU to prevent any issues. This was well before the Firefox tab crashing issue happened. So I'm not sure if it can really be the issue of a faulty CPU, but I've also had issues of other programs randomly crashing recently (like Discord or Steam).

The tab crash can occur on any website, for example Youtube, Duckduckgo, Protonmail, etc. The crash reason always is either "EXCEPTION_ACCESS_VIOLATION_READ" or just "EXCEPTION_ACCESS_VIOLATION". The crash also most of the time (but not always) occurs when loading the page itself or a video / live stream on it. But not when browsing an already loaded page (for example this forum post page I'm writing right now).

Here are some of the crash reports I've submitted:

EXCEPTION_ACCESS_VIOLATION_READ: https://crash-stats.mozilla.org/report/index/60309ae8-8cad-43ac-8b9b-172b10250815 https://crash-stats.mozilla.org/report/index/fecef0ab-d874-4cb5-990b-e49650250815

Rather rare "EXCEPTION_ACCESS_VIOLATION": https://crash-stats.mozilla.org/report/index/114b26fa-4e10-442c-bbd5-406630250812

Could someone help me narrow down this issue? Can it really be a faulty CPU and I need to trade mine in?

I've seen the other support requests on this from the past. Setting " print.tab_modal.enabled = false " doesn't seem to work now (Firefox for Mac 141.0.3).

Is there any (2025) way to default to "print with system dialog" rather than having to choose the link off of FF's dialog every time? It makes printing to PDF (which is 95% of my "printing" from FF) needlessly tedious.

When setting up 2fa. I scan the QR code. Enter the 6 digit pin generated by google authenticator. Download my backup codes and enter 1 when prompted then firefox says sync time and try again. I am running Ubuntu and have an android phone. Ubutu is set to automatic date. time and timezone. My phone is also set to automatic date&time. I have enabled seconds display on Ubuntu and phone the are synchronized to the second. I have tried this on multiple computers. Google authenticator works with all 9 other 2fa logins I use it for. I have tried many times and asked AI what I'm doing wrong Grok said I am not doing anything wrong after walking through the entire process. I have tried clearing cache and deleting cookies, signing out and back in without success. Please help I use firefox as my password manager and love it but want it to be as secure as possible.

thank you very much. Thomas

Firefuxxed was refusing to open new tabs so I shut it down and restarted it (always fixes it) and all my pinned and open tabs were gone with no way to recover them, it took me half an hour to manually restore the pinned ones one by one but not all of them as I cannot remember all of them let alone all the open tabs I had (hours of research gone down the toilet).

There should be a way to backup and restore pinned and open tabs so this doesn't happen, the history option does nothing.

OS: Linux Mint 22 fresh install from a week ago Previous version of Firefuxxed updated after this shamossel.

I asked a question about a week ago. I can't even see the question anymore. While this was going on I received these emails. All times are in Australian CST.

I am as much a believer in security as the next person but I don't understand what is going on,

I have had no response to my original ticket, which I beleive was number 305857 which I can no longer find any refernce to in my account, and I still have a completely blank Library! and I can't even make any new bookmarks!

Plaes help, Yours sincerely, Ms Jacq Felis (AKA Kaelkitty).

For a week my pinned tabs are lost every time I open Firefox. I have checked my settings, they were the same as always. I have de-selected them, closed and re-opened firefox, selected them again, closed and re-opened again, pinned my tabs again. Then closed and re-opened firefox and still they are not there. I have done this multiple time with the same results. This seems to have started after the last update.

Firefox loads in some images very distorted where they are pixelated and in negative color. It's not all images, it's also not on specific websites, it's just in general. Some websites don't have any problems and others are practically unusable. The icons in my tabs are often desaturated from their normal color as well, see the youtube icon for example the color is very muted versus the actual color of the logo.

Hello Mozilla Firefox Team,

I would like to request that Firefox include the Somali language for website translation.

I choose Firefox because I have been told it is more secure, but currently, it does not support Somali. This makes it difficult for me to read news and websites in my native language.

Adding Somali support would provide a better user experience for Somali speakers and improve access to online information. It would also encourage me and others to continue using Firefox as our preferred browser.

Thank you for your consideration Abdi

Up until recently Bing Maps in the UK has the option to display Ordnance Suvey Maps and the function to measure distance.

Now, using Firefox, Bing Maps display a Beta version with very limited functionality. Using Microsoft Edge, Bing Maps have all the functionality that I expect.

Has something changed within Firefox that has caused this problem? Is there something that can be done to allow Bing Maps to work correctly from within Firefox?

i have a big problem with settings of privacy and security. the problem is i cant edit this option ( Allow Firefox to automatically trust third-party root certificates you install ) and its greyed out . i made everything ( refresh - troubleshoot - uninstall ) and with the first click on singing my account on Firefox and add my restore my add-ons after setting up windows this option become unavailable (greyed out) and cant edit it. i need a solution without going to set up a new windows because its so tiring to set up a new windows to edit this option. please give me a solution its emergency. thanks a lot.

Hello there,

Before (an update perhaps?), it was possible to click on a star icon located in the toolbar and it'd open the bookmarks like the bookmarks1 screenshot. Now, it requires to first click on the sidebar thingy, which allows to access the icons on the far right, which includes the bookmarks icon in question.

There's also another icon for bookmarks that can be put directly in the toolbar (bookmarks2 pic), yes, but it doesn't show all the bookmarks right away, it's not the same

So the question is: how do I do to get the Ctrl B Icon/shortcut directly in the toolbar, like it was before? I don't want to be obligated to use the sidebar when I have plenty of space left in the standard toolbar..

Thanks in advance!

I have my credit card info saved and previously I could click on a credit card and it would autofill the numbers for me. Now the credit cards still show up when I click on the space to put the credit card number in but but it wont fill the info into the form. I just get a blank space after I click on the saved credit card. Any suggestions on how to fix this? Thank you for your help.

I am logged into my computer. When I try to sync my phone Firefox with my computer, I am asked to provide a number from an authentication app. I don't have any such authentication app and can't figure out what the Firefox one is. There does not seem to be a workaround. I can't use a backup code or reset option. I am trying to figure out what to do.

Thank you

I go to:

General

Startup

I have the box selecting Open previous windows and tabs.

I close the window.

FIREFOX DOES NOT EVER SAVE MY PREVIOUS TABS. When I select

History

Then select: Recently closed tabs

Then select: Reopen all Tabs

NOTHING HAPPENS.

Yes, I'm a bit peeved at this because whenever I am stupid enough to close Firefox, I lose all my tabs. And it ain't just a couple tabs.

HELP??
