Firefox Community Forum

I keep receiving a popup seeming to be from McAfee security regarding a virus on my computer. It isn't from that security firm. The ad locks my system till I shut off and restart my computer. This is very annoying and occurs on all installed browsers. Is there anything I can do about this annoying thing?

Hello, I am currently using Firefox Beta and I would like to switch to the regular Firefox Release without losing any of my data (browsing history, bookmarks, passwords, add-ons, and settings). I would appreciate guidance on the safest recommended method. Specifically:

Is it safe to install the Release version over Firefox Beta, or could this cause data loss or profile conflicts?

What is the best way to create a full backup of my Firefox profile beforehand?

Should I expect any issues with add-ons after moving from Beta to Release?

Do you recommend enabling Firefox Sync as an additional safeguard, or is a profile backup enough?

In case something goes wrong, what are the recommended recovery steps?

My setup:

Operating System: [windows 10 ]

Thank you for your assistance.

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

if i search something on firefox the search bar doesnt show english and after clicking enter for the answer sometimes it doesnt come in english. i have chosen english as the only language but sometimes i get results in bangla too. i want my results to be in english only.

Which version of Firefox (Windows, Mac & Linux) will make the local network access (LNA) enhancement generally available? We at Box would like to inform our joint enterprise users and administrators to expect this enhancement and provide them guidance on how to manage this change.

1] Topic list is insufficient; 2] I tried to use the share data option of <;tblshg ; > troubleshooting. It could not automatically collect data, so I returned [back icon] to the form and found the form blank. The write-up I had spent well over an hour preparing was simply GONE.

No reply needed, buy that needs a fix. how could that ever pass QA.

Although set to open previous pages and tabs it doesn't do so, furthermore I must sign in to all e-mail accounts, google, Facebook etc every time I open my Firefox Developer Edition

I uninstalled Firefox on my computer and reinstalled it, but when I logged in, the account couldn’t sync, it was as if the sync couldn’t retrieve any data from the server. Nothing happened at all.

On my Android phone, the data is still there, but when I tap “Synchronize now,” nothing happens either. I’ve tried signing out and signing back in multiple times, but still nothing works.

I also tried switching to a different computer and a different internet connection, but it still didn’t work.

What should I do now?

On my Facebook feed/timeline images don't show when I use Firefox and they are visible when I use Microsoft edge browser. I googled and I found this explanation: The most common reason for photos not showing in your Facebook feed is that an add-on or extension you have installed in your web browser (often Firefox) is blocking the photos being loaded from Facebook.

Will someone, please, tell me the answer to my question

I want to avoid any 'ai assist' searches because I do not find their summaries accurate or valuable enough to be worth the environmental impact they consume. I know my web browser searches are not under the control of firefox, but for privacy and security I kill cookies when I end browsing sessions. So I am not staying logged in to search engines when I finish my sessions, and setting my preferences to 'no ai assist' on DDG doesn't last session to session because the search engine defaults to 'ai assist' searches now, as does google.

Are there any search engines that do not use ai?

Has anyone written an extension/add-on to FF that would add 'minus ai' to all my searches no matter what browser I use? Or otherwise indicate to search engines that I do not want ai-assisted summaries period?

We've got various privacy options built into FF--this is why it is my preference always--and it would be LOVELY to have a 'no ai' option too.

This is only an issue in the firefox browser - chrome, safari and edge are fine but the drop down text in firefox on some form drop downs is a weird unintelligible font

Hi, I am using Firefox Developer Edition though I have had this problem with Firefox in the past. The problem is that sometimes the audio from Firefox just stops working, everything else in Windows works but not firefox, I tried having the same youtube video on Firefox and Chrome annd it worked on Chrome. There are times that a Windows restart fixes it and there are times that I just have to wait a couple of days till it fixes itself. The only thing I could find to trigger this behavior is to have mi Bluetooth earphones connected, then disconnect them and sometimes when reconnecting them the audio is just gone. This usually happens when I am working, when I start the day I put them on and start some music on Youtube, after 3-4 hours I do a 15 minutes break and during that time I charge the earphones, when I come back and turn them on again, most of the times the audio is gone. Is this a known issue or something? I can send anything if you want. Thank you

I am on Windows 10 Pro (extended to Oct 2026) and use the Firefox profile manager at startup since I have more than one profile. Today (11/12/2025) I attempted to start Firefox and the profile manager window would not populate. the window was blindingly white on my dark background. I closed and restarted umpteen times but it refused relentlessly. I was about to uninstall firefox and then decided to see if I had actually installed it on any of my mobile devices. And indeed I had it on my ancient Apple iPhone 7+. And it was synced! I refreshed the sync and indeed it picked up my most recent activity from last night. All tabs were synced. To make sure I had another synced copy I also installed it on my iPad. I synchronized this too and suddenly my desktop browser started working again.

I don't know what caused the lockup of the Profile Manager but I am afraid it might happen again. What causes this and what can I do to regain control without having to reinstall? I am a researcher and I have over 1000 tabs open.
