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!

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?

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.

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 am so tired of this. I am continuously being blocked from webpages because Firefox says I am not able to access them. First it was Macy's website and now it is my bank website. I have just gotten a new computer this week, but it was occurring on my previous one. I am 71 years old and am not a computer whiz on these situations. I was able to access my bank account this morning but not now. Total bullcrap.I really liked Firefox, but if it continues I will switch to something else. I just received this error code.

I have firefox as my default browser with Bitwarden extension. I use yahoo and sign in for browser. I also have outlook for email. Maybe a month back, when signing into yahoo, I would type in the first few letters and bitwarden login options would appear. They still do but selecting one seems to do nothing now. If I open bitwarden and try autofill from the login file, it says it cannot autofill, items must be copied and pasted. Its odd that in yahoo home page login the options appear but do not autofill as they used to maybe a month ago.

3 times now, my account has completely reset, forcing me to log into everything again and not working with the key that I copy and pasted and downloaded. I would like my old data back. Why does this keep happening?

I'm on the local network. When I use Firefox to download a very small .docx file, the download gets stuck and doesn't move, taking a while to complete. But with Edge, it downloads almost instantly. Please help resolve this issue.
