In particular, this is running Firefox 139.0.4 (64-bit) under Windows 10, and finding a huge file and activity here: C:\Users\Lab\AppData\Local\Mozilla\Firefox\Profiles\4wyhpro4.default\cache2\entries And, if I simply delete everything there, it seems like it regenerates fairly quickly, whether I've been using the browser or not. What are these strange entries, which look like this growing list:

Hi there, so my old laptop of 10 years, finally crossed the rainbow bridge! Dead in the water! I have a shiny new machine. And now I need all my passwords, etc. How can I make this happen? The old laptop is a goner, no hard drive, no nothing. Any help would be greatly appreciated. I read other threads and most seem to talk about copying info from the old profile/whatever. I am unable to do that. Thanks in advance!!!!

i can't find the setting to have Firefox open a new tab when a site is selected from bookmarks. It is opening the bookmark site in the tab that the user is on at the time of opening bookmark site, thus overlaying the current site (tab). Thank you.

Recently the Temporary Cached File cannot be totally cleared, it remains always now at a minimum 2.6mb, why??? Before earlier this year it was 0mb when temp. cache cleared, what is going on?

I downloaded Firefox to update my address bar so that various search engines could be used. This was ok for the evening. But next time I booted up, FF reverted to what I had before. How do I make the address bar searches permanent. The FF version I am currently using is 139.0.4.

For about the past 24 hours when I go to youtube to check out a video - nothing works? I clicked on a video to play, got the sound and no picture. I closed out my browser and I kept getting the audio of the video and had to shut down my computer to stop it. Now when I go to a video nothing works. My cursor disappears when I go to chick on the video and I have to move it off to the side just to see my cursor.

I also use a service (VidIQ) that helps me see the tags on the right hand side of my screen for a video and the channel so that I can compare those tags to my videos that I am uploading.   Now that never load just a spinning dial or object like it is stuck.

I hope that you can get this fixed soon or let me know if there is something that I must do at my end.

Thank you,

Hi, I already know that Firefox, especially LibreWolf, is probably the best browser along with TOR and Brave about protecting against fingerprinting. However, after reading this paper https://arxiv.org/abs/2506.00719 about browser fingerprinting via WebAssembly I am wondering if and how Firefox, LibreWolf, can protect us against it. I already read this https://support.mozilla.org/en-US/kb/firefox-protection-against-fingerprinting, but I could not find any reference to such protection. Thank you

Doing any search brings up result page that just has my query and a search magnifying glass - not the search results as expected and working on Mac.

This is 2 days old only as of 11 June 25.

Crying here as I depend on it sooo much; this is a work PC and DDG is my go-to for research.

i installed firefox browser in my pc. when i opened firefox before i logined to my account it synced with edge . when i logged in to my firefox account it synced and updated my passwords to my old passwords. i lost all updated passwords. is there a way i can recover my passwords

Recently I've noted that tabs on my browser move from where I had them all the way to the far right end of the tabs list, and it happens at random. There'll be times when I click on another tab while listening to music or a video on another only to find the tab I was listening to had moved when I go to click back on it. Without fail, I've found these tabs at the far right end of the set of tabs, and I need to know how to put a stop to this. It's inconvenient, and annoying in extreme. This has to be due to a recent update, because up til a couple months ago, this didn't happen at all. If there's a setting that I can change in about:config, I would like to know about it, because you can bet I'll disable this feature.

I have tried many times to download and install firefox but when I try to install it, and sait for what seems to be theinstallation process to finish, I keep getting a page that says invalid URL.

How can I insall the prowser?

Actually, I used to have it on my computer but somehow I cannot find it. [email removed]@aol.com

Open previous windows and tabs stopped working. I have gone to settings and made sure the option was selected, which it was, so I proceeded to refresh Firefox, no difference. I deleted Firefox completely and download it, then reinstalled it again. Still not working. How can I fix it?

Hi I have found a few times now that if a website calls for information to be input in a form and then submitted the submit doesn't work. However if I bring up chrome then it works fine so I guess it is either one of my settings or a problem with firefox...?

I enabled Microphone Access for the Doximity website (https://www.doximity.com/dialer/home/voice) but it continues to require that I click "Allow Microphone Access" every time I try to place a call. Please see attached screenshots. Is there any way to fix this, so that I don't need to click "Allow Microphone Access" prior to every single call?

I use Firefox (139.0.4 (aarch64)) on my Mac as my daily browser. I also use Firefox as my primarly browser on iOS (139.1 (56110)). My passwords simply don't keep synced between the two. I'm logged in to both using the same Mozilla account. Some passwords sometimes sync. But many are missing on iOS, and many that are there are out of date. I've done the usual like logging out and in again, I've tried forcing sync manually, passwords are set to sync on both devices. This has been going on for years now and I'm at the point where I'm going to have to switch browsers as I can't keep not having access to my passwords on my phone. Any ideas on how I can fix this? Thanks!

PLEASE HELP! I allowed Avast to do a "clean up" this week. That usually entailed a "scan" for viruses. NOT ANYMORE! My computer is really messed up! I just tried to delete Avast, and even though I hate to see ads, I think their Ad Blocker is messing up my PC. I just noticed that when I asked what I thought was FIREFOX a question, the answers were supplied by an entity called THLIOKNI. WTF is THAT?????? Seriously, what is happening to my relatively NEW PC--had to buy a new CPU in October of 2023. And I've always used Firefox. But WINDOWS 11 is the operating system on this PC, and it is NOT compatible with Firefox apparently! I'm an elderly woman and I cannot handle this stress! What I also noticed is that I read Substack writers and depend on them for accurate description of current political and social news, but now I can't access the "like" buttons on commentators. Is that a Substack issue (I don't think so!), or is it something to do with the Avast "clean up?" WHAT ON EARTH IS THLIOKNI and how the hell did that get on my computer? PLEASE ADVISE ASAP! And I sincerely hope a REAL PERSON reads this! I do not want a million responses from other readers at other times, I want to hear from a REAL PERSON! You have my e-mail address. Catherine O'Kelly

When I use non-incognito browser to go to https://www.truist.com and enter a login and password that is valid I receive a JASON response message window that says {"type":"about:blank","title":"Bad Request","status":400,"detail":"Failed to convert 'userIdEncrypted' with value: ","instance":"/dias/authenticate"} If I use a new private window I can login normally. Others have said the same thing but the suggested remedies do not work. I have delete all cach, cookies, and site data associated with the truist.com domain and the same problem happens. If I use Edge all works well with the truist.com site. Where does this useridEncrypted come from? Anyway, I thought I would try to clear out the userid which was prefilled in with the help of Firefox and just retype my id. Viola, everything worked. So wherever Firefox is retrieving the saved login id from, that must be corrupted somehow. Hope this will help somebody that is experiencing this problem.

I downloaded the most recent Firefox update (version 139.0.4) and since then, Firefox has been prompting me to restart to continue using Firefox every day. When I give the go ahead to restart, I get a pop up that says I need to either exit the Firefox client completely, or create a new profile to continue using it because Firefox detects an older version (this is even after updating it manually).

It's made about 5 profiles since the 10th, and they're all still in tact. I clicked my very first one and it very much still works (and even gives me a popup when I open it in a new window that says Firefox is using the latest version). It's been really disruptive to my work flow as it has happened several times in the last two days. I keep checking my settings and it says that I'm updated to the latest version of Firefox, but it continues to kick me out.
