I have been a long time user of FF and have been puzzled by it's recent failure (to both start, and subsequently re-install) For the last 18 months I have been running Win 12 without problems. That is until last week, when I can only assume the Tuesday udates ( MS) has created havoc. I would appreciate any assistance as I am not fond of MS Edge, or Google Chrome. Dave Hickman.

After installing Firefox on a new Windows 11 computer, when I click on the Desktop icon, a Firefox window opens but it doesn't open previous Tabs and the Application menus does not work. I can open new Tabs though and it downloads websites. If I click on the Firefox icon on the Windows Taskbar, Firefox operates normally.

Why doesn't the Desktop icon start Firefox so it works correctly?

Thanks

Hi,

Every time I restart my Firefox browsers they will sign me out of my Mozilla account. I can see the email address associated with my account and 'Account disconnected'. I have to go through the process again every time I use it. I am using default privacy & security settings.

I am using :

140.3.1esr (64-bit) on Debian Trixie 143.0.4 (aarch64) on MacOS Tahoe 26.0.1 143.0.1 (64-bit) on OpenSuse Tumbleweed 20250929

Can you please help me resolve this?

I was signed out from my Firefox-Account on my PC for no apparent reason. I reset my Firefox Sync Password today and when I checked my saved passwords they were empty. In my profile folder there is a logins.json.corrupt file which probably contains all my saved passwords. How can I recover them and why doesn't Firefox sync them back like it's supposed to?

Thank you.

I have just completed migrating my files and settings from my (not so) old windows 10 desktop computer to my windows 11 laptop. Everything seems to have gone ok, except that the Firefox bookmarks were installed and only work in the private browsing window. When I start Firefox normally, the window that opens does not have the bookmarks, and even if I enter a web address manually in this window, it will not connect. I can choose "New window" in the drop down menu and that window will have the bookmarks, but still will not connect. The only way to get the bookmarks and also be able to connect to the internet is to choose "New private window" from the drop down menu. The problem with that is that there have been occasions when I have had a need to examine my browsing history, which I can't do since Firefox doesn't save the history when in private window mode. I have tried the procedure to sync bookmarks, history, etc., but the procedure is somewhat confusing and didn't work for me. Can you simplify the procedure for me? Thanks, John Blakley

Have never liked the bright orange Firefox icon, it's too dominating on my desktop, I LOVE the older brownish firefox icon, it's just right. So every time you come out with a Firefox update I get out "Resource Hacker" and change the icon to the older one, pictured below. I mentioned this before, asking if you could just give that option, and didn't receive a response. You come out with so many updates, it's a hassle changing the icon every time, but I'm willing to pay the price to escape the distracting bright orange icon, but now suddenly Firefox won't let me alter the icon in the exe. Was wondering if you'd have any suggestions. Have used Firefox exclusively for decades. Thank you very much.

Firefox Context Menu - Unwanted Navigation Images are Showing Again

Hi All,

I was using the following CSS to hide the navigation images and show only text labels on the context menu for the Back, Forward, Reload and Bookmark Page menu options...

/* Content Area Context Menu - Navigation Vertical Text */
#context-navigation,
#context-navigation > menuitem{
  flex-direction: column !important;
}
/* hide images */
#context-back image, #context-forward image,
#context-reload image, #context-stop image,
#context-bookmarkpage image{
   display: none !important;
}
/* show text labels */
#context-back:after, #context-forward:after,
#context-reload:after, #context-stop:after,
#context-bookmarkpage:after{
   content: attr(aria-label) !important;
   margin-inline-start: -19px !important; /* this pushes navigation text items to left, aligned with other menu items below */
}


It worked up until a couple of versions ago, but something has changed, and my CSS is now broken, and those navigation icons are back.

My context menu now looks like the attached image below.

Any help with showing only text labels on this menu is appreciated.

Thanks.

On all our computers it seems impossible to sign into Outlook...several laptops and 3 desktop...even a new Apple device. Enter your email address and then taken to the next page (see attachment). sign in works with Edge! This has been happening for maybe a month. Very frustrating! NEVER opens the next security window, the 'spots' just keep moving forever...selecting "Back" just repeats the cycle.

Since the recent Firefox upgrades, I am no longer able to log into the social security site using ID me. Previously, I logged in with no problem but now get a 400 error message saying the website is too large. Of course I have emptied cache and cookies and reloaded Firefox but nothing works. Apparently the error lies within the Firefox upgrade since before upgrading, there never was a problem logging in.

The issue started about one week ago (today is 10/11/25). When I wanted to print while in Firefox browser, the print never executed. Instead the screen froze as did the browser. I had to do some experimenting to use my pointer and open a different browser. Yes - besides the pointer being frozen (all that showed was an hourglass) my keyboard was also frozen. When I finally opened a different browser and printed the same item, no problem. I had to close Firefox to be able to fully use my laptop again. I searched the solutions and none had an effect. Firefox would still freeze/hang/lock up when trying to print. The browser is up to date.

In one of my Firefox installs, the Profiler automatically starts recording every time I open Firefox. There's a button on the right that looks like a speedometer and it is blue until I tell it to stop. Then it is taskbar button color.

Profiler instructions at https://profiler.firefox.com/docs/#/./guide-removing-profiler say to simply drag this button off the toolbar and it will stop record. On restart, it's back on the toolbar, and it's recording.

I have tried refreshing Firefox. Doesn't help.

I have tried uninstalling and reinstalling Firefox, and then setting up a new profile. Doesn't help.

I have tried deleting prefs.js. Doesn't help.

I have tried opening up the developer console, opening settings, and unchecking "performance." Doesn't help.

I searched the registry and found a key called MOZ_ENABLE_PROFILER (iirc, something like that). I set it to zero. Doesn't help. I then deleted the key entirely. Doesn't help.

How do I get rid of this thing? It must be a registry setting of some kind, as it appears in whatever Windows account I open Firefox from, but I can't find it. It is deeply frustrating as the computer it is happening on is my oldest computer, and I don't want a recorder running in addition to Firefox.
