Diễn đàn hỗ trợ Firefox

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!

Hello all, I have the same exact problem described in post https://support.mozilla.org/en-US/questions/1463436, dated 9 December 2024. Until ten days ago (more or less) all was working correctly. At the beginning I thought there was a problem with Intesa because Intesa had problems in all the country in that period, but I have now tried CHROME and found that is working correctly. My system uses Firefox 139.0.1, W10-32 and Iliad FTTH. I have already cleaned cache and data from settings but the problem remains. Any thought? Thanks very much for any help. Mario.

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!

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

When I type into Firefox www.gmail.com the message returned is "Looks like there’s a problem with this site https://searx.space/mail/u/0/ sent back an error. Error code: 404 Not Found

When I try to access Google Maps the message returned is "Looks like there’s a problem with this site https://searx.space/maps/place/Taman Bay/@45.3126101,36.7266254,12z/data=!3m1!4b1!4m5!3m4!1s0x40ee93c055efa761:0x94911e600ea680f6!8m2!3d45.2873681!4d36.7542667?hl=en sent back an error. Error code: 404 Not Found

When I try to access Google Translate the screen returned shows a listing of 74 online SearXNG instances.

What is going on? Why is Firefox pointing to SearXNG sites rather than Google? Grateful for advice of a fix. [I have eset Internet Security installed.] Unable to attach a screen shot at the moment - nothing will save just now as I have an eset scan running.

Bonjour,

I forget my Mozilla account password. I follow the process ( forgot password selected) I receive an email from Mozilla on this mailbox: [email address] ; here the part with code If this was you, here is your confirmation code to proceed: 18884199 I don't receive a second mail or any information to proceed with this code. It don't work in the login password window.

Thank you for help!

Whenever I close Firefox and try to reopen it, it brings up a system error that says, "The code execution cannot proceed because C:\WINDOWS\system32\pmls64.dll was not found. Reinstalling the program may fix this problem." I've tried completely deleting Firefox and reinstalling and it opens a new tab, but when I close it i get the same error message.

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

I am repeatedly getting this pop up window after starting my computer and selecting the Firefox icon in the toolbar to start the browser. When using the Firefox browser I always update Firefox when prompted, so it should be the latest version, unlike what it states in the popup window. If I want to use the browser, I have to sign in to the browser and sync my data and I have to re load all my tabs from my history. It is time consuming to the point where my colleagues who were using Firefox have uninstalled Firefox and are now using a different browser. I could do the same...but I want a solution. I'm using Windows 11.

I had an issue with the hidden task bar not showing up when I moved my cuser to the bottom of the screen, so I was "playing around" and messed it up. I created another profile, but lost all my bookmarks and so forth. I copied files from my old profile to the new profile, but now I can't get to michaels.com - it won't load. Also, I have my yahoo mail tab looks like it's loading, but I got in my email and when I went to blackforrest.com it does the same thing.

I still have the issue of my task bar not "unhidding" when I go to the bottom of the screen. I have to minimize my screens to see the task bar.

Can you help, please?

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'm running Firefox 139.0.1 on Mac Sonoma 14.7.1.

Since FF V138, I've had this extremely frustrating problem where, approximately once a day and while the application is still running, Firefox seems to either auto-revert to an older version' 'or otherwise mess up the installation files. I don't get any notice this is happening until I try to open a new tab and it brings up the "You must restart Firefox" notice. When I click Restart, it pops up with "You've launched an older version of Firefox, so you won't keep any of your bookmarks because that would be unstable" error.

The only way I've found to fix it is to redownload the most recent install files, which, after the fresh install, will allow me to keep using Firefox with my bookmarks for the next 5-6 hours, before the whole process starts again.

I theoretically have auto-updates off; my settings are set to the other option, "Check for updates but let you choose to install them". Doesn't seem to make a difference. It only does this on my Mac; the FF install on my Windows machine works fine.

I really want to keep using FF. It's my preferred personal browser. But this is really messing with me! I was hopeful that 139.1 would fix it but same issue, so far.

I cannot get past the secure connection failed! I have cleared cookies, cache, etc. I have turned off the firewall, and restarted my computer more times that I can count....

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.
