Firefox Community Forum

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.

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.

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

When I open Firefox it can't find my profiles when I go into the profile manager it shows no profiles. Going to my computer I find the profiles where they should be. However under program files there is a Mozilla Firefox normal directory. Did they recently change default install areas or did something else screw up.

I have done malware scans using Malwarebytes and spybot and my antivirus program and all comes up clean. Windows is up to date, Windows 11 most current preview. I can't tell you the current Firefox version since it won't open without the profile. I did just create a new profile and Firefox version is 147.0B7. also just recently right after what I think was an update that lost all my open windows and tabs and there is no way to restore them if there is a backup anywhere

I have a gpu rtx 50 and recently decided to use rtx super resolution to improve watching online videos but I can't make it work on firefox, I'm currently using the DEV Edition x64 latest version HW Acceleration is enabled and I also tried modifying via about:config the lines: media.peerconnection.video.use_rtx gfx.webrender.overlay-vp-super-resolution gfx.webrender.super-resolution.nvidia

It still doesn't work! tested in the other versions of firefox and it also did not work Using brave, chrome and edge..works normally without having to do anything. Does anyone know what it can be???

All searches get blocked by reCaptcha, quoted as being caused by 'unusual activity on the network' After going through the "I'm Not A Robot" process the search is o.k., but this happens for every search. The problem does not exist if I switch to Chrome. How do I fix this?

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

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

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.

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

All of a sudden I cannot check out using shop on my IMAC. It has worked for me for years and now all of a sudden it stopped. Not sure what settings to edit. I can go through the check out process, but when I press check out the page will not load. I just get a shadow & spinning like it's trying to upload but it never does. If I switch to Safari I have no problems, but I prefer Firefox. Any suggestions or solutions appreciated. Lorri

Over the last five hours, I have gotten 27 emails from Firefox Monitor for this data breach, for the same email address. I have already marked the breach as resolved in Monitor but I keep getting emails. Is there anything I can do about it?

I do not want my searches to be reflected in the address bar. I believe in prior versions of Firefox there was a checkbox to delete that provision. I'm using Firefox 123.0 64-bit with Windows 10 and have been through the setting and more tools areas but found no way to remove that function. I did try the about:config suggestions but still have no joy.

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?
