My laptop unexpectedly closed Firefox after it crashed and upon a restart I re-opened Firefox, which normally restores all my open windows/tabs from the very last session no problem whenever it force quits due to laptop crashes. But this time when opening, it restored windows/tabs from almost a month ago. I closed Firefox and checked the sessionstore-backups folder: - the recovery-backup files are from the session date I just re-opened with old tabs - the previous.jsonlz4 file is from about a month ago and seems to be the reference point used when restoring tabs rather than my actual last session

Is there any other file or method I could use to recover my actual prior session tabs before it crashed?

I have not re-opened Firefox since quitting the browser after seeing it restored the old tabs.

Thank you in advance!

Hello, I have just installed Firefox version 144.0.2 on a new computer. I have access to all of the Firefox files and data on the original computer, but I am not able to run Firefox on that computer. Therefore, I am not able to create an export file from the original installation. Is it possible for me to import all of the original Firefox data into the new installation? Thank you very much in advance, Steve DeFeo

For past few weeks, Whenever I try to update FFX on windows 11, it fails. It takes me to another screen and tells me to download Firefox. When I try to download it , it aborts with this message.

"download.mozilla.org has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site."

To download Firefox with new version I have to use another browser but no choice. Then with new version of Firefox, I have faced the same issue of update and used same approach to update firefox to a newer version.

This error appears for some google sites as well but the same occurring for firefox download site itself is not understood.

I have over 100 open tabs spread over 4 Mac desktops. I can no longer access ANY of them after upgrading to macOS Tahoe 26 and installing ESET Cyber Security Pro. I've used ESET with Firefox for many years without ANY problems. But now I have to choose between uninstalling ESET and being unprotected in order to use Firefox AT ALL. Every single webpage is blacked out with the message below. ESET support says that Firefox needs to issue an update to fix this problem.

Hi!

Please see attached image:

Left: Edge (making sure it isn't a network issue)

Right: Firefox using a new profile from about:profiles.

On my main profile, I've tried clearing the data and cookies (though not the history) a couple of weeks back.

Any suggestions welcomed! Many thanks in advance.

I read firefox is dropping linux 32. Are there any alternatives?

I only use the internet to watch youtube videos.

I don't feel like having to buy a new laptop for this.

Mozilla, in their infinite wisdom, sent me a note about something new in firefox, by displaying it in a new instance of Firefox.

It wasn’t until I closed my normal session, that I realised a new instance of firefox was also running, and shut it down on.

In shutting the new instance down after my usual session, it overwrote all my normal tab settings🤬

Q1. Are my normal tab settings recoverable? Q2. Why did Mozilla think it a good idea to open a new instance of Firefox to send me information, rather than simply open a new tab.

NB This is in Windows 11

Is there a fix or workaround?

Hi All,

I was using the following CSS to hide the navigation images and show only text labels on the context menu for the Back, Forward, Reload and Bookmark Page menu options...

/* Content Area Context Menu - Navigation Vertical Text */
#context-navigation,
#context-navigation > menuitem{
  flex-direction: column !important;
}

/* hide images */
#context-back image, #context-forward image,
#context-reload image, #context-stop image,
#context-bookmarkpage image{
   display: none !important;
}

/* show text labels */
#context-back:after, #context-forward:after,
#context-reload:after, #context-stop:after,
#context-bookmarkpage:after{
   content: attr(aria-label) !important;
   margin-inline-start: -19px !important; /* this pushes navigation text items to left, aligned with other menu items below */
}

It worked up until a couple of versions ago, but something has changed, and my CSS is now broken, and those navigation icons are back.

My context menu now looks like the attached image below.

Any help with showing only text labels on this menu is appreciated.

Thanks.

Firefox had been a safe haven for anti-AI, and used to be my go-to search engine. If this AI bullshit continues, no one will respect or use the browser. Stop implementing AI garbage that steals data

Hello,

i was trying to check my apparmor stuff because of the warning on Linux. Now i tried duck.ai to instruct me , but created more damage than anything else. It said to set firefox in enforcement mode, now it wont start (well im using Firefox right now in complain mode)

How do I fix this problem that everything runs normally and safe?

Hello, I'm writing here since I lost hope in Microsoft's support. I've seen some other people having the same issue from like July, this problem however started with me around the end of August. Every time I try to log into my hotmail I get the screen attached. The only way to get around it is to delete the cookies/cache related to Live.com and try again. Also, right now, I have to "sign out" from my email to avoid saving cookies or cache related to my login information - otherwise, I will have to do the process again (of deleting the cache/cookies). The thing is, I've always used Firefox to check my hotmail, and I wouldn't log out of my hotmail and check back in quickly any time I want to - the process now is getting sluggish. I've contacted Microsoft (or let's just say, tried to) but I kept going in loops and never got an answer. So I'm here in hope I get any ideas (and I have a feeling that it is something from Microsoft's side and not from Firefox side because the problem occurred suddenly and not after a specific update to Firefox).

Thanks

Hello, since I installed the Firefox 141.0 update today, I can't login to Reddit. I tried logging into Reddit right after updating Firefox, so did a System Restore to see if that corrected the problem, and it did.

To double check, I installed the Firefox 141.0 update again, and encountered the same problem logging into Reddit again, so it's definitely this new update causing the problem.

I've attached the Reddit messages I get. The 1st is the initial message, and the 2nd after I retry logging in.

I would greatly appreciate help with this.

Thank you,

Michael T.

Firefox used to save unknown files according to the save files setting. i.e. ask where to save files. Now if opens unknown files as text in a new tab.

How can the correct behavior be restored?

Alternately, can the Linux snap be fixed to allow saving of new file types? {The procedure shown in https://support.mozilla.org/en-US/kb/change-firefox-behavior-when-open-file is not present in the firefox 141 snap.

This is the message I receive when I try to sign in to my Adobe account online:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at auth.services.adobe.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

How do I check that Firefox has permission to access this page? Or, what else do I need to do to sign in to my account?

Thank you!

Hello, we were just assigned brand new laptops at work. I had IT install Firefox for me, and I'm attempting to sync my firefox account with my previous one so that I can load all the open tabs I had on my previous laptop. I appeared to have signed into my account just fine on the Mozilla pages, but when I go to the hamburger menu in the top right of the browser, I see no icon for my profile, nor any option for "sign in and sync" like the help guides are instructing me to click on. I can't pull up anything related to syncing in the settings, either. What exactly am I missing? Any help is appreciated, thank you!

I rebooted my laptop with both firefox windows I had open and possibly a private window too, then rebooted again without touching firefox, and now I can only restore one of the two windows. I checked my recently closed windows in history and there was nothing there at all. Is there anything I can do at all to restore that other window or is it just gone for good now?
