Firefox Community Forum

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:

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.

I use this extension daily. It's annoying to have to put in my settings everyday. When I used this extension on Chrome, I didn't have to put in my settings daily. I set them once and it saved them. But Chrome no longer supports this extension. Is there a way another way to save my settings? I don't want to have to do it everyday....

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!!!!

`about:logins` display a blank page while there's no network connected. (please see the figure)

Is it reasonable that passwords stored locally cannot be accessed offline?

I am on a MacOS 15.5 and the latest Firefox build. Opening this link https://adobe.ly/444sG14 leads to the heavy stutter of the Firefox window.

I hope that I chose the right Category. Issues as per Title. They have all disappeared when I signed back in. Syncing appears ok. When I open the Extensions Folder near Profiles, it's empty? Have a FF 32 digit Recovery Key. Good for anything?

About a month ago I go to Facebook to play my usual: Angry Birds. I enlarge the screen and it goes blue but it never goes back to the original color. I tried getting out resetting...nothing. If I click on certain spots it will go back to it's original color but then when I click on something else it goes back to being blue. It's hard on my eyes. I sent a question to the actual website and was told it was something on Mozilla's end when a update was done. I go to play Angry Birds on a different platform and it's normal so yep, as usual it's Mozilla/Firefox. Can ya'll please fix whatever code ya'll have for the enlarge feature? I hate having to go to different platforms just to play one game.

Dear FF/Mozella staff,

  I have been using FF for many years with Windows 10, every time I launch FF it starts up, brings me to my start screen of favorites, and then shows itself still downloading on the top taskbar pane, but everything is already loaded on screen. The cursor will then not change to the hand pointer to follow links on screen. the bookmarks open to blank or unresponsive pages. Closing and reopening FF gives the error message that processes are still running and do I want to open a new window with FF, but that is unresponsive as well. 

back to internet explorer, Thanks for that

Issue is just what the subject says - when I restart my computer, Firefox sync logs out and my browser resets to defaults. When I open my browser it's as if I'm setting it up for the first time.

I am signed into Firefox on two computers, but this is only happening on one of them. The setting to 'Delete cookies and site data when Firefox is closed' is not checked.

Any idea what could be causing this? Thanks in advance.

Hello, Today I updated my firefox and lost all data related with my firefox acc. Passwords, bookmark.

How can I recovert it? It was in sync before update it.

"autofill logins & passwords"

Recently firefox updated to v139.0.4 (64bit) after the update I disabled "autofill logins & passwords" but every time I turn on the pc the username/login, on webpages (amazon,facebook. webmail), populates the field.

I never had this issue until the update, previous version "autofill logins & passwords" has always been disabled ie never shows...

I do NOT want the logon info for "autofill logins & passwords" populated...

I am repeatedly (a couple of times a week for the last several weeks) losing bookmarks. It is possible for me to regain them when I follow the instructions given by Firefox, but I am frustrated with having to do it repeatedly. I am including below the instructions I am following so that someone out there might be able to identify the root of the problem.

I updated to Windows 11 Pro, version 24H2 on May 2, 2025.

My suspicion is that a "helpful" friend made some sort of error. Earlier this spring, he deleted Microsoft Defender Malware Bytes (I think) because it was interfering with bookmarks. Maybe it has something to do with running Windows 11. If all that sounds confusing, it's because of my lack of technical expertise. I will be grateful to anyone who can help me.

Quite often when I enter a url Firefox will start showing connections of the status bar. It appears to be forwarding the url to other sites before showing what I expect.

I don't understand why this happens. Using the Windows 11 browser goes right to url with no waiting.
