After I restarted my Windows 11 last night at 6:38 EST, Firefox updated to 139. I lost all my open tabs and history, and I've lost a day of work dealing with this. Help!

So I just noticed after downloading the new update to Firefox, version 139.0.1 that something new came up in my task manager called Crashhelper. Never seen this before. Closed it down and it seemed to have no issues shutting down at least. I haven't had Firefox crash in recent months, so I'm assuming that this cropping up might be a glitch of some kind? I looked this up to see if anyone else had this issue, and it seems someone on Reddit did encounter this, on Linux, and another on Windows also seems to have run into it. How do we stop this from coming up whenever we start up the browser?

I have no idea what just happened. I went to log off a website and a notification popped up that said "Check browser's developer console". I searched here for "developer console" and there were 0 results. I did log off after the 2nd try so it's no big deal but I'm just wondering what that notification meant. It sounds kind of serious. What did it mean? Thanks!

Just updated to 139.0.1 and got a surprise. My New Tab Favorites Icons now have Push Pins in their upper left corners, leaving less space for the icons, so of course my icons are now smaller than before. Why do the people maintaining the system at Mozilla keep messing with the New Tabs? Last time, they thought they needed to include a large image of the Firefox icon, again shrinking the remaining screen real estate for my icons. That got fixed. Now they decided each favorite icon needs a rather large push pin to indicate that it belongs there. Somebody thought this would be a good idea? Why can't they just leave it alone?

I'm posting two screenshot images of my New Tab screen. You will know which is before and which is after.

Once I visit any web site that uses HTTPS there is approximately a 90% chance it'll take seconds or even minutes to secure the connection. This never happens on other browsers as they load such pages instantaneously.

I already cleaned my data up and removed the extensions, both suspected and innocent bystanders, to no avail.

As stated in the title, I'm using Firefox 139.0.1 x64 on Windows 11 (24H2, build 26100.4061). This started happening after an automatic Firefox update, I never changed anything in my system configuration.

I have just noticed today that I cannot login to Reddit with FireFox. After researching the issue, I can confirm the following:

- Followed all steps in: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems - MalwareBytes is not installed - Confirmed latest update of FireFox installed - Adblocker/Ublocker disabled - Deleted caches/cookies - Refreshed Firefox then restarted in troubleshoot mode from: Help > Troubleshoot mode > restart > refresh - Created a new profile and tested - Confirmed FireFox is not limited/restricted from accessing private/public network - Confirmed signing into Reddit from other browsers is successful

Please advise how to fix this as FireFox is my primary browser and I'd rather use it for all of my activities screenshot of the error message attached below

Yesterday (Sat 5/31), I woke up to the 139.0.1 update, along with a new behavior that Firefox will hang (and require a Force Quit) any time I click a pinned extension that opens a drop-down interface (e.g. 1Password, Adblock Plus, Pocket).

I've tried disabling all extensions and bringing single ones back (as well as disabling Pocket via about:config) - the result: any extension that opens a dropdown causes the hang, and any extension that runs without opening a dropdown works just fine, regardless of the combination of extensions that are enabled/disabled at the time.

I tried opening Troubleshoot Mode (although it's of little use since my problem seems rooted in extension behavior) - the first several times I tried, it ALSO caused a hang, but now I'm able to turn it on & off without an issue (though the page rendering is wonky within it - I imagine that's just a Troubleshoot Mode thing?). For whatever it's worth, I think the change that preceded it starting to open without hanging was my disabling this [setting] (though it didn't cause any change in the original behavior, which was my initial goal).

I'm running macOS 14.6.1 if it's of any use. Thanks for any troubleshooting ideas!

On the Firefox Home page, I have 2 rows of shortcuts I filled with pinned URLs I need for my work and I have been using this from years now and it's saved to my account so I can import them between different laptops I use. Today, I woke up to find all my pinned URLs are gone and have been replaced with some random URLs, some of those seem to be coming from the recent history but the others I have no idea from where they are coming from. This issue is happening today on all my laptops connected to my Mozilla account.

How can I restore my pinned URLs back to Home shortcuts? It will be a nightmare to go back and find some of those URLs I pinned and pin them again one by one ☹.

Things I tried: 1. Open and close Firefox. 2. Logout then login. 3. Manually trigger a sync.

When i register a new computer it freezes on Sync and i wait 15 minutes and even not 1 site synced. i already have 3 PC in Sync,, but i need it in one another PC but Sync freezez, i have tried 2nd new PC at my office and still same plroblem. i added 2 nd email, also downloaded APP on phone, signed out and then renew,, but no result. please fix it and send me an answer ;) in this PC it is synced already.

New update has affected the performance of Jun's Journey. Specifically, a white "mist" now covers all play areas of the June's Journey game. Wooga - the operators - advise it is not their issue. Others are experiencing the same since update

Firefox keeps crashing and Hanging and I get the error message "gah your tab etc" I have followed the advice for fixing the problem but it keeps coming back Its really annoying when you are trying to do something I'm no computer whiz and I have looked at the crash reports, its just gobble gook to me, I need help to fix the problem.

Windows 11/Firefox/Google

Firstly, my apologies, but I only have a very basic understanding of computers.

I somehow ended up fiddling with a side bar on the right hand side of my screen, and the next thing I knew I had lost the ability to have multiple tabs open on my screen. I tried google a solution and came up with this:

"View>Cusomise toolbar in browers. Look for the new tab button. If its there, drag it back to the toolbar, typically to the right of the existing tab."

I tried that, but it didn't work. The plus sigh came out on the left rather than the right of my search bar, and every time I clicked it I just got a new page, rather than a new tab being added to the existing one.

I would be grateful if anyone has a solution to this issue.

This warning appears on so many pages since up the Firefox update that it's making it difficult to actually use Firefox. And your suggestion "To see this page, you need to open it in a new window", doesn't work. Clicking option + the link doesn't offer a chance to open a new tab or new window. And the block is still there when I copy and paste the desired link. Two of the biggest issues are on highly reputable sites (a bank and a telecom). I suggest you fix this "upgrade" because other browsers don't have this problem.

For the better part of a year now I have to reinstall FireFox almost daily. It just stops opening tabs. I get a tab crashed error and the only way to get it to navigate to websites is to shut down FF and reopen it. Then at least half the time when I shut it down I get a new error that this is an old version of FF and I have to create a new profile. I'm not interested in creating a new profile. I've had this one for years and years. So then I have to use Chrome to download the FF installer again and reinstall to get it to work. I really prefer FF but it's almost unusable at this point. What is going on at Mozilla that their browser no longer works on Windows 10 or 11?

Abandonment of Pocket is pushing me back to use of my Firefox Bookmarks Tree.

After a long period of maintenance on my Firefox Bookmarks Folders within the "Bookmarks Menu" I accidentally moved a folder named "Music" into some other folder. I've checked the folders which contain nested folders which are near to where the "Music" Folder should be but cannot find the "Music" folder.

It seems that Firefox Browser ver. 39.0.1 (aarch64) on my M4 MAX MacBook Pro 16" running macOS Sequoia 15.5 makes it easy to search for and to find a bookmark, but not its location within the folder structure in which the bookmark is located. I need to see that folder location so that I can move the folder "Music" back to the top level within the "Bookmarks Menu."

What facility is provided by Firefox for me to perform this search?

I've been using Firefox since Windows first came out and NEVER had this problem (or any other) until about a month ago. After an update, my bookmarks sidebar failed to work. I tried to update again, but got the message "Secure Connection Failed". After many tries, I was able to load a 32 bit ( V 1390.1) which was offered from Mozilla. This despite the fact that my PC is a 64 bit machine. This 32 bit version works poorly! I've repeatedly tried to load a 64 bit version, hoping that it would work as Firefox has in the past. I am still getting the the message "Secure Connection Failed", Error Code Mozilla_pkix_error_key_pinning_failure. What is going on??? I like Firefox and I'm reluctant to change browsers, but it may become necessary. Operating systwm: windows 10. Bob N
