Firefox Community Forum

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

macOS 15.6 Firefox 141.0.3 - my preferred browser

I've seen a number of posts regarding this problem since the Firefox 141 update. I've tried a number of suggestions, although my problem seems slightly different.

I can apparently login to reddit OK but when I try to access a subreddit thread, a warning comes up - see image.

I have cleared Firefox site data, cookies, cached files, etc - problem remains.

I have restarted Firefox in Troubleshooting mode - problem remains, so not an extension.

However, https://old.reddit.com has no problems with Firefox, lets me access threads, etc and comment.

No problems accessing reddit with Safari or DuckDuckGo browser.

I deleted all the shortcuts from Firefox desktop browser's homepage and now I cannot add them back.

There are no blank shortcut icons on the page anymore. No setting to enable them. Shortcuts are enabled. Page is mostly blank, only has Firefox icon.

I tried to close and open Firefox as well as disabling and enabling the shortcut setting. Adding more rows did not do anything.

Before this issue occurred, I had one shortcut on the page that was linking to localhost. I opened the edit window to the shortcut and pasted the same address and saved changes. After that I removed the shortcut. All of the blank tiles immediately got removed from page and I had no way of adding more shortcuts.

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 am now receiving this notice for more and more commonly accessed websites. I get the message if I have https only selected or not selected. Currently receiving for Lowes, Home Depot, American Airlines and more. I can go to a Firefox 135.0.1 browser on a separate desktop accessing the internet through the same router and do not have issues. I suspect I have been upgraded by Mozilla into a less functional browser version for whatever reason that Mozilla does this.

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?

When I have multiple tabs open, around the 6th tab, the entire computer freezes. I have to press the physical button to shut down and restart. This behavior started with the last Firefox update. It doesn't happen when I use Brave browser. What changed to cause this?

I'm running Mozilla Firefox for Linux Mint mint 100 - 1.0 version 141.0.3 (64 bit) on Linux Mint 22.1 Cinnamon. These are the latest versions of Mint and of Firefox for Mint.

After my bitwarden add-on failed me, I remembered ChatGPT helping me with this another time - but I got it wrong. I right clicked the extensions button (I have 3 add-ons falling under that button) and removed from tool bar, thinking I could then reinstall it and the Bitwarden issue would rectify.

Instead, the extension icon disappeared, and is nowhere to be located. ChatGPT wants to do some reconfiguring but surely there's a better way. I have looked in "customise toolbar" (ie, right click toolbar, click customise toolbar and look for the icon" - but the puzzle piece icon is not there.

Surely I have hidden the puzzle piece icon somehow and I need to do some sort of magic to make it reappear... Have never had this issue with Firefox previously.

How can I customize the headers and footers of a print job? Specifically, I want to change where the header and footer info appear on the page, i.e., left corner, center, right corner. I'm using Firefox Browser version 141.03. Under Print > Options, the only option is to show or not show the headers and footers. There is no option to EDIT them. Thank you.

I am an EX EU employee and have access via a double authenticated procedure to the "EU LOGIN" which gives me access to several internal webpages of my former work organisation. The most important is the access to the HEALTH SERVICE, which actually is blocked since one week-- and now it seems like this-- through your web browser. I am an ancient Mozilla user and supporter. After claiming my help desk in EU that my EU LOGIN is blocked, I got the answer, try to use another browser- and I saw that with another browser it worked. What happened with Mozilla? Do you want me to go to apple-microsoft or what ever?

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 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!

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.

My Macbook Pro's Firefox has a convenient bookmark toolbar, my Mac Air's FireFox does not. Can I find a setting on the latter to restore my settings from the former?

No matter how many times I visit Amazon.com, it WILL NOT show up on my Home Screen as an ICON. I have tried 2 Rows and 4 Rows. I visit amazon many times in a week, sometimes many times in a day and it never shows up on the Home Screen after my last Firefox Upgrade to 142.0. Before the upgrade, it was always on my Home Screen. I have deleted many ICONS hoping it would somehow fill in as I visit Amazon - but it's not happening.

How can I fix this?

Thanks!
