Dear all,

For some time now my Firefox browser is crashing while I use it. Then a loop starts where a window appear with buttons offering to Restart or Close Firefox but whichever I choose it takes several sets of open/crash to stabilize when in the end if offers to either open it again, or refresh Firefox. I don't wan to refresh because I have tens of tabs that I want to save. But I can't because OneTab, along with all other extensions, is being disabled after the restarts.

I have a crash ID of one of the latest occurrences of this phenomena: f6ef62ad-b072-46b8-8bc8-0d3ca0240708

Please advise!

Hi firefox community,

I am using Firefox version 127.0.2 as my main browser on MacOS Sonoma 14.5. For the past few months, when using Firefox in Mac's full-screen mode, I've been experiencing an issue where one of the multiple open tabs unexpectedly displays in a separate window the moment I click on it.

This behavior didn't occur previously, and I believe it started happening about 3 months ago. It doesn't happen every time, but occurs a few times a day when I least expect it, making it difficult to identify the specific conditions that trigger it. I use a Magic Trackpad, and after switching to full-screen using the three-finger gesture, the moment I try to activate a specific tab, that tab alone displays as a separate window in full-screen mode.

Is it possible that a Firefox version update has changed this behavior? If this is a Firefox issue, is there a way to capture debug logs to have the developers investigate it?

Alternatively, if there's an option to prevent tabs from opening in new separate windows, that would be an effective workaround. Could you please let me know if such an option exists?

Best regards,

I am having issues signing in to the playstation store using firefox. It works on edge (although I have the same issue in ungoogled chromium). I have tried refreshing but that didn't work. I uninstalled it and deleted all mozilla folders in appdata, then tried again without signing in to my mozilla account on a fresh install but i'm still having the issue. It might be a windows configuration issue because I don't see why this would work on edge but not on firefox. I've tried disabling all cookie and tracking protection features but I still have the same issue.

Since v128 update my right click menu contains all possible items and doesn't work. For example, right clicking a video and changing playback speed has no effect.

I already tried running troubleshoot mode to no avail. Tried manually add-ons to no avail. I even uninstalled and reinstalled to no avail.

v127 worked fine. Please investigate.

Hello,

I experience constant tab crashes a couple of days now. I tried safe-mode and re-installing the browser. But the crashes still persists. This only happens with firefox.

Been trying to identify the problem. Here are some crash reports. All of them have the signature (unloaded T_Prevent64.dll)

When I scroll down the page on MSN and try to open a link in a new tab the page jumps back to the top. It then opens a link of another article that I never right/left click on. I have my mouse set up to left click to open a new tab. Does not occur on any other sites.

It has been doing this for months now.

Hi Firefoxers, I've recently returned to using Firefox after using Chrome, Vivaldi, and Brave for a long time. Most Firefox things are better than these, but I find the bookmarks handling in Firefox extremely frustrating in comparison.

When clicking the bookmark star, the edit bookmark box pops up. The location dropdown gives me a list of 7 recent folders where I can store the bookmark. If I click "Choose" a tiny little box opens up and, in this extremely cramped space, I have to scroll through hundreds of folders and all their expanded subfolders to find the one I want.

One way other browsers solve this problem is by letting the user right click directly on their bookmarks folders and select "Add bookmark here", which then automatically saves URL, page title etc to that folder. But in Firefox, this just opens up a blank "Add Bookmark" box that doesn't contain any info about the current page, meaning you have to manually enter all the details.

So I'm interested in any help advice about:

a) Increasing the number of recent folders in the location drop-down to make it a lot more than 7.

b) Increasing the size of the "Choose" box so I can see the list of hundreds of folders more comfortable.

c) Stopping all folders being automatically expanded in the "Choose" box.

d) Making Firefox auto-add the details from a current page when clicking "Add Bookmark".

Any help would be appreciated!

I have Firefox 129.0 64 bit on 2 laptops, Laptop2023 and Laptop2024. I would like Laptop2024 to match Laptop2023. If possible, would like to copy the Profile, or at least the Bookmarks. The web articles direct me to Help options which do not exist. I do not want to reset anything on the sending laptop.

I have instructions on how to copy bookmarks from years ago, but Firefox has changed so much that they no longer work. How to I copy with the current Firefox version? If possible, email bjedrick@verizon.net.

I do not have any ad blockers and have disabled "Block pop-up windows" in Firefox and turned off "Enhanced Tracking Protection" for sites but I still get the message that I am blocking ads.

I had a crash on my SSD (WIn7 Ultimate) - " Operating system missing" error. I saved the data and want to reinstall Win 7 and import previous Bookmarks data to new install of Moziilla Firefox.

I transferred the sqlite file (s88qn337.default) from the previous install (now non working system) to the existing working Firefox directory (C:/Users/My Name/AppData/Roaming/Firefox/Profiles/xxx.default.

I then renamed "default.XXX.old" (the previous install had only one file in the Profile directory - ie s88qn337.default)

When I try to open Mozilla Firefox, with the single file (s88qn337.default) in the Profile directory, I get the error "Can't find user data".

When I then open fresh install of Mozilla Firefox on working SSD (Win 7 Ultimate) and try to Import Bookmarks, the options are only "Import Bookmarks from Explorer" or "Import from html file".

How to resolve this problem, please?

I'm trying to get my Firefox installation to permanently disable private browsing mode, however, all information I can find is for the Snap version of Firefox, and not for the Flatpak version. How do I disable private browsing on my installation?

As of a few days ago whenever I start Firefox the window appears with the Bookmarks sidebar panel already opened. I click the "X" on the sidebar and it will close - until the next time I start Firefox. If I choose Menu->View->Sidebar->Bookmarks and uncheck it the panel will close - until the next time I start Firefox. No matter how the Bookmarks sidebar is closed, it will always reappear when Firefox is restarted. Even if I switch to some other sidebar, Bookmarks will replace it on startup.

I've searched about:config and found no setting which seems to control sidebar behavior on startup.

I assume this is the result of some recent update. Is there no longer a way to permanently disable the Bookmarks sidebar?

MacOS 12.7.5 Firefox 127.0 (64-bit)

For a while now, I've been having recurring issues with Firefox desktop freezing and becoming totally unresponsive. If there's any pattern to what causes it, I haven't been able to notice it; sometimes it happens as soon as I open the browser, sometimes it happens after several hours, sometimes it happens twice in ten minutes, sometimes it happens twice in a few hours (however, I can count the number of days it's happened less than twice in one day in the past few weeks on the fingers of one hand). When the browser freezes, it becomes totally unresponsive - it doesn't fade or display "Not Responding", and Task Manager shows nothing abnormal, but it doesn't accept any input at all, any video or other animated material that may have been displaying freezes, and it can only be "fixed" by force quitting from the task manager and reopening. This is exclusively a firefox issue; other programs open at the same time as the browser freezes are not affected.

The only real lead I have as to what could be going on is that sometimes, things don't freeze all at once, but in a cascading effect. For example, tabs, bookmarks, etc. might not highlight when moused over, but still accept the clicks, or selecting another tab might causes the address bar to display the URL of the selected tab, but the screen displayed in the window will not change. Once these cascading changes start, they generally progress to total freeze before I have a chance to do much with that information (only a few seconds), but it's unusual enough behavior to be worth noticing.

Things I've already tried that haven't fixed the issue:

• Reducing the number of tabs used and otherwise reducing Firefox's system resource usage has not impacted the problem in any way.
• Running in Troubleshoot Mode has not had a consistent effect on the problem (the most recent time I did, the browser ran stably for longer than I could stand to use the internet without my ad blocker, but this is only one data point in an already inconsistent spread; prior instances of the problem have occurred in Troubleshoot Mode)
• Disabling hardware acceleration has not fixed the issue.
• The issue has persisted through multiple refreshes and at least one full uninstall and clean reinstall.
• The issue persisted after creating and switching to a new profile multiple times.
• The issue persisted after renaming places.sqlite
• The issue persisted after clearing cache and cookies multiple times.
• The issue persisted after clearing downloads and history.
• And very likely some other stuff that I'm forgetting, I've been trying to fix this on my own for a while now.

My website is http://bigelowdesignco.com

As of today and today only Firefox refuses to show my homepage like it's supposed to, and instead it only shows some strange webpage I have never seen before saying "Account not found".

I opened my website on Microsoft Edge, Google Chrome, Safari, and Firefox on my iPhone with zero issue. However, I have check Firefox for desktop on two different computers, and been shown the same page.

I have already cleared my cache, history and cookies. I also uninstalled Firefox and did a fresh install, only to have the same problem.

I'm just really confused what happened as this has never happened before. I got scared someone hijacked my website, but that wouldn't make sense since it's working on everything but Firefox on my desktop. I've just never seen this "Account not found" page before and this page has nothing to do with my website, domain, or hosting. My website and domain are all on Squarespace.

For a long time I've used Firefox on Linux with multiple instances each with their own profile folder. Today when I try to run these instances with separate profile folders I get the following error:

> Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile.

Profiles are created like this:

firefox --new-instance --createprofile "PROFILENAME ~/.firefox-PROFILENAME"

They are run like this:

firefox --new-instance --profile "~/.firefox-PROFILENAME"

It seems something has broken with the instance isolation as this is now throwing an error. Additionally I run "createprofile" it doesn't seem to actually create the folder.
