Using Firefox 145.0 (64-bit), "Firefox is up to date" on PC with Windows 11 Pro.

I was so pleased when Firefox's Group Tabs arrived. I often have about 12 tabs open to do Railway research. So I thought, Group Tab, great idea. Save a group of tabs as one tab. Instead of creating a Bookmark Folder and each time opening all bookmarks from said folder, what better way to do than opening one tab. Or so I thought. I also created a "SHIP" tab for my hobby in the shipping industry, so I could have two group tabs that could be collapsed making the tab bar tidier. I saved an closed each group tab then closed down my PC. Next on restarting, Firefox starts up automatically as chosen by me. Both RAIL & SHIP tabs reappeared without me doing anything. Great! However yesterday, I inadvertently opened another Firefox window, forgot it was opened. So when I shut down my PC, I closed the Firefox browser and then discovered the over Firefox window I had opened. Closed it shut down my computer. Of course when I opened my PC today, Firefox started automatically, but with the tab that I had open in the last Firefox window. No problem I thought, I will just open the saved Group Tabs. It was a problem, where are the Group Tabs saved? Could I find the location? NO! I looked in Bookmarks, all the various History lists, even the down arrow to list all tabs. Nothing, the Group Tabs are none existent. I have checked on the "about:config" section for Group Tabs and everything is enabled "true". So where are the Group Tabs saved? I have been with Firefox for around 14 years, often citing it as the best browser. But over the last five years I find myself using Chrome more and more. Chrome has Group Tabs which do not not need the users to save them, they are saved automatically, and are easily found on opening the Chrome browser. Why doesn't Firefox have this?

After upgrading my Firefox to version 145, a blue line appears at the top of the browser window when it's in full-screen mode and the current window is focused. I know this is to remind the browser window that it's currently focused and interactive, but I really hate this notification and want to make this conspicuous blue line at the top of the window disappear. I couldn't find a relevant option in the Firefox browser settings. Does anyone know how to set this up?

Please help me to disable this focus tip,thanks!

This morning when I started up Firefox it had a pop-up about the new profiles feature, asking to create a new profile. Just out of curiosity I clicked the create profile button to see what the interface would look like. Since I didn't actually want to create the profile I hit the delete button, but nothing happened. So I closed the window. I then tried delete the new profile (then called "Profile 1") by hitting the trash can from the choose profiles screen. Still nothing happens. At this point my original profile window is still open, but I close everything to restart Firefox in hopes that it will allow me to delete this profile I never wanted to begin with.

The Choose profile window comes up, I select original profile and nothing happens. I can open the new "Profile 1", which I have since labelled "Bad Profile".

D:\Users\<USERNAME>\AppData\Roaming\Mozilla\Firefox\Profiles doesn't appear to have my original profile anywhere.

I'm deeply concerned this beta feature I never asked for has deleted my original profile when it should have deleted the new profile.

Lately , when clicking on the link in the Winloot Live emails in order to enter , quite often the link causes Firefox to freeze. Task Manager shows that the memory usage more than doubled. Only way out is to use task manager to end Firefox. Possibly an issue at the site itself. Anyone else seeing this?

Hi, da anscheinend Firefox zu faul ist um einen eigenen Support an de start zu bringen, muß ich es auf diesem weg probieren. hauptsache man kassiert die kohel für die plazierte werbung. bei einem Win10 64bit starte Firfeox nixht mehr. auch nicht als admin. wenn ich es anklicke, passiert nichts und ich bekomme es auch nicht im taskmanager angezeigt neuinstalation bringt nichts danke euch

Firefox did an update and "couldn't find XPCOM" and crashed. Uninstalled and re-installed but now my Firefox icon opens a website "nine.com.au". I WANT MY FIREFOX BACK!!!!!

Reporting an ongoing issue where the Saved Credit Cards section is missing from Firefox’s settings. Autofill for credit cards still works in the browser, but I cannot view, edit, or delete any stored cards because the entire UI section is gone. The Payments / Saved Credit Cards section does NOT appear under Settings → Privacy & Security → Forms and Autofill. Autofill still fills credit card data, so Firefox clearly has stored cards. I just can’t manage them.

Older threads are now closed. Here is what I already checked

I confirmed the following in about:config: extensions.formautofill.creditCards.enabled → true extensions.formautofill.creditCards.available → true Set extensions.formautofill.creditCards.supported → "on"

Restarted Firefox

Whenever I use FF to get a PDF file, It is corrupted. It seems to download ok. It will display, but copying from it yields garbage. Using apples Preview for speaking yileds jiberish. I do not have this problem with Safari

I had this problem for months even before my latest OS was install. Mac mini, M2, Sequoia 15.7.1, FF 145.0 (aarch64) kleps@uic.edu

Hello!

I use a VPN when I access the web and I recently updated my OS (Mac OS Tahoe). I updated Firefox and now DNS over HTTPS (DoH) is enabled in Firefox. When I have my VPN enabled, I cannot access the web, there is some problem with DNS resolution. I have changed my Firefox DoH settings to Standard (I have also used Strict) and have typically been unable to resolve web URLs correctly. There have been a few times that I have been able to use 'Standard' DoH strictness / settings and also use the VPN successfully at the same time, but typically when I have the VPN enabled Firefox cannot access whichever 'mozilla.cloudflare' address it is attempting to use for DNS resolution.

The VPN vendor suggested always using the VPN's DNS resolver. I have done this and I still have the same problem. What should I do to ensure that I have secure DNS and can successfully use a VPN?

Thank you.

I am unable to log in to my BT internet mail account using Windows 10. I must clear history every time I try or change accounts. BT tell me they do not have a fault & the problem seems to be with my browser. Can you please help I did not have this problem in the past using Firefox. Many thanks Ken Robinson

It looks like with this new version of Firefox I have to load my saved password file every time I start the browser, and even after doing the reload some of the passwords don't work forcing me to change them, and I would have to do another password save, but if I forget to do it and close the browser all the passwords are delete. I did not have this problem prior to this new install.

Also I prefer to use Firefox as a browser I feel it is way better than Edge and Chrome even though it doesn't work one a two websites I need to use. one only works on chrome the other only works on edge.

Let me know if you need other information.

Long-standing problem with Firefox: when printing some webpages with text on letter-size paper, the last sentence on a page is sliced off, with the remaining slice printing on the next page.

I put the same URL in the Opera browser, and across several scale factors, it breaks the page cleanly without slicing through thelast sentence.

A fix is long overdue.

I recently opened Firefox to see a new flagged warning under my toolbar that says "The security sandbox is disabled. Your configuration is unsupported and less secure."

I have gone into about:config and adjusted every security.sandbox element to see if that would change anything; it did not.

I am running on Windows 11 Home so I cannot install or properly run Windows Sandbox.

I would either like a solution to enable the sandbox once again, or just remove the notification from the toolbar.

recently Firefox has started leaving a small gap at the top of the window with the desktop background (the light blue in the screenshot) is visible when the window is maximized.

This issue doesn't occur with any other program and occurs in troubleshoot mode.

Hello,

I am having an issue where my menu bar continuously shows up. If I create another tab and drag it to create a new window, it goes behind my active window. When I try to change to that window it continuously opens the menu bar and refuses to allow me to change. I have to minimize my current window and drag the other window to get it to focus. Alt + Tab does not work to swap between them. Every time I click an application and click back to window the menu bar appears again, sometimes I have to click 3-4 times before it goes away.

I have tried made sure it was not my keyboard with an alt key stuck, tried multiple browsers, only firefox is the issue. I've created a new profile with zero extensions, the issue persists. I've also completely refreshed firefox with no success. Made sure all my drivers were updated and restarted the PC, unhooked the keyboard, nothing works - it continues to have issues. Running out of ideas here. I've also tried the below below solution for the menu bar and again, no luck. Any help would be great. Thanks!

The attempted menu bar fix I've tried:

Type about:config into the address bar and press Enter. Click "Accept the Risk and Continue". In the search bar, type ui.key.menuAccessKeyFocuses. Double-click the entry to change the value from true to false. Restart Firefox.
