Diễn đàn hỗ trợ Firefox

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

I opened a profile that I had just used recently to a blank tab bar. I closed it and the sessionstore-backup folder did not have a recent backup, The most recent about a week old.

Just for testing, I tried to restore with one of the upgrade.jsonlz4 file, about 2 weeks old, but it also had no session. I then restored one that was 2 months old. That one had a session

Now, Firefox no longer generates the upgrade.jsonlz4 files

Just recently I am no longer able to login to the discover.com site in private mode. It still works in regular mode. I'm using this on a desktop, not the discover app. I spoke to their tech support and tried to do a login while on the phone. They told me nothing was coming through on their end. So, what changed and how can I fix it please?

Dzień dobry Mam otworzone strony Facebook i Mesengera.com w przeglądarce i nie mogę wykonać połączenia wideo i dzwonić do osób prywatnych, na grupach to działa. Natomiast do osób prywatnych nie podświetlają się ikony telefonu i kamery i tym samym nie mogę się połączyć, jak to naprawić? W Chrome działa. Dzięki za pomoc.

When I attempt to log into my ssa.gov account thru either login.gov or id.me with firefox browser i get the following message. "Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit." I can access both with google or edge. I am running windows 11 with most recent firefox update What do I need to change in my firefox settings?

Hey I changed my password before reinstalling the Windows but when I reinstall Firefox and logged in, all of my information was gone since Firefox doesn't back up after password change so I uninstalled Firefox since then because it was useless to me. I was looking through my files and I find that I still have the previous recovery code before changing password, can it be used to recover my passwords and bookmarks?!

I was googling something related to my game and i clicked on a Reddit search result, which i made sure is the official Reddit website not some shady one, then an empty .htm file from moz-safe-about resource got downloaded randomly. I didn't open it, i uploaded it to VirusTotal which came out safe and then i instantly deleted it and ran a virus scan with Windows Security which also came out clean. i tried to recreate this by opening the same website again both on Firefox and other browsers like Zen(Firefox based) and Chrome but nothing happened.

is this a harmless bug or should i worry that it could be a virus that didnt get detected?

Please can someone be kind enough to assist me. I cannot seem to log in as normal and therefore cannot get my emails and therefore are not able not reply to them.

Doing a "find" ends up showing a greenish (so I'm told) background with white text. Want to guess which "find" in the attached image is difficult for me to find?

What I would like: Find (focus): yellow text on black background Find All: white text on black background

Yes, of course it would be nice if that would auto switch to black on yellow if the website default is black background.

I can hack userContent.css and get the selection function to work:

/* General highlight (for text selection, etc.) */

selection {

   background: #FFFF00 !important;  /* Yellow background */
   color: #000000 !important;       /* Black text */

}

I can hack userContent.css and get the Find All (sans the focus) to work.

But firefox always provides the focus with white on green. Even if I do something like this:

/* Customize the color of highlighted search text */ input[type="search"]:focus::selection {

   background: #FFFF00 !important;  /* Yellow background */
   color: #000000 !important;       /* Black text */

}

I tried several themes. No change. I tried changing Windows Preferences. No change.

There must be a way to make this "find" feature useful for me.

When I went to my Firefox password page there was a red banner saying my website was hacked and my passwords stolen a year ago. That message was not on that page a month ago. Please advise urgently.

I had chess scores and high level thinfags i had done I wanna be able to save them even if there locked i don't give my email to just anyone because its always full but I keep scoring high close on chess and your browser keeps deleting it. Now I could do it on a normal tabe but its capped and if you cant do it I know Google has the ability I just tested it out yesterday and they have a save incognito tabs with pin options so if tou guys cant help me and give me my lost game scores and elo im deleting the app permanently today and just switching to Google, Thanks for reading Ps this happened yesterday and there was a screen lock and I chose yours because I thought it still might be easier but the screen lock went away and now I lost all of the hard work I put in thats very frustrating

Whenever I try to use Reddit Firefox refuses to display most media elements. This has only been a problem since the recent upgrade to 145. I've tried refreshing Firefox. I've even re-installed it, using a totally new profile.

Is anyone else experiencing this? I get the following message (image attached) in the console if I inspect one of the elements involved.

Greetings, I have a problem with Firefox taking too long to load websites after login, while Edge loads websites immediately. It happens every time I lift the laptop lid and login. I have restarted Windows 11 and tested the load times of Firefox and Edge a while ago by going to Google. Edge loaded Google after 5 seconds, while Firefox 3 minutes and 25 seconds. That's long. Sometimes Firefox loads a webpage 10 minutes after login.

What could be the issue here and how do I fix it? I have the following extensions and I'm sure that they do not hinder Firefox.

I have purchased a new computer and do not want to loose the info in my Mozzila account. How do I install the old account to the new computer? Old computer has windows 10 os new computer has windows 11 os.
