Firefox Community Forum

There are three accounts I have to use regularly to pay bills.

On one of them (PG&E), FF is useless. Can't even log in.

On the two others, banners come up that say FF is unsupported. Both still usable for the moment, But the future....

I fear FF is going to become unusable/irrelevant in my work-flow in the near-term future if the trend in my skewed sample continues.

On Mac, when FF is idle for a few minutes, its widow disappears...

Often happens also on "main" screen (laptop) intermittently.

To bring back I have to click on the FF icon on the Mac LaunchPad.

Have tried playing with hardware acceleration off/on and setting up "separate spaces" for monitor and "main" screen. None work.

Found an app to generate clicks periodically at the (x,y) of the FF icon on the LaunchPad, but such is mickey-mouse and not really acceptable.

A few versions back (sorry, can't saw how far back), the above was not a problem.

I did file a bug on Bugzilla, but have seen any acknowledgment. Similar problems are recorded on the 'net.

I know that typically mozilla does not put a low bound on advisories, and https://www.mozilla.org/en-US/security/advisories/mfsa2024-40/ is the advisory for vulnerabilities fixed in ESR 128.2. CVE-2024-8387 is listed here. yet the advisory for 115, https://www.mozilla.org/en-US/security/advisories/mfsa2024-41/ does not list this vulnerability. Was this something that was only impacting 128 (for the ESR builds) or is there a mistake that either 115.15 did patch it but it wasn't documented, or the patch has been missed and ESR 115 is still vulnerable?

How to shrink this vertical space? (see attached image)

Ever since 131.0.0 my shortcut icons got all messed up so I am trying to restore the original look. I've already removed the giant Firefox logo and made my icons larger. Now I need to condense them so I don't have to scroll to see them all.

Here's what I have so far in my userContent.css:

/* Minimize the size of the logo and wordmark on the Home/New Tab pages */ @-moz-document url(about:newtab), url(about:home) {

 .logo {
   background-size: 0px !important;
   height: 0px !important;
   width: 0px !important;
 }
 .wordmark {
   background-size: 0px !important;
   height: 0px !important;
   width: 0px !important;
   margin-inline-start: 0px !important;
 }

 /* Expand the shortcut icon images to max size on the Home/New Tab pages */
 .top-site-outer .tile .icon-wrapper {height:100% !important; width:100% !important;}

}

I recently started having a problem with my banking website. Before I could investigate or report it, Mozilla released a bug fix 1923500 "Firefox 131 Enhanced Tracking Protection major breakage of multiple banks Bill Pay services" I have updated to Firefox 131 however, there may still be a problem, however before I report it I'd like to verify if it's simply that their link is broken. Let me explain: On my bank's website there is "Payment Inquiry" link with this link "https://paybills.MyBankName.com/imm/Auth/SLO/4661?ReturnUrl="

What happens is that it sends me back to the login screen, I navigate to the Payment Inquiry again, click the link... rinse and repeat... in an endless loop. I suspect that the URL is malformed because there is nothing following the "=" sign. I would expect something to follow the equal sign. Is this indeed a bad URL? Should I pursue with my bank? I only ask because is seemed more than a coincidence that this occurred near the same time as bug fix 1923500.

Hi,

I have an odd problem with a friend's Firefox and Thunderbird on Windows. The font changed to white in the address bar, the tab titles, some content on websites, some elements of the settings etc.

From what I can see there is no difference to my settings under "Language and Appearance". When I create a new profile either with the profile manager in Firefox or by renaming "%appdata"\Mozilla Firefox", nothing changes. So I can rule out a custom userchrome.css or similar in the profile folder. When I switch to "troubleshoot mode" with the old or the new profile, everything looks fine.

It also affects Thunderbird, but no other programms.

I can't figure out, where the problem lies.

Hello,

I am running Firefox 131.0.3 on Ubuntu 16 on a 32bit machine. When running Firefox Desktop in a Command Line Terminal, I am getting error readouts that look to me like hacking attempts. The errors reference a "Sandbox". I have copied the error return text for your Tech Support people to analyze for security vulnerabilities. These errors are accompanied with the processor use going to 100%, and the machine locks up.

Thank you, AJ

I have appreciated Firefox for many years, so long in fact that I no longer have access to the email address that I signed up with. I have had no reason to access my account so I did not realise that it was out of date. I was accessing my account to check that I had two-factor protection and since I could not access the account I decided to create a new account and used the help pages to move my profile to the new account. I was able move my profile and access all my bookmarks and PASSWORDS! I simply uninstalled Firefox, moved my profile to another location, downloaded Firefox and copied the old profile over the newly created profile. I opened Firefox and could open the password manager and see all my passwords. I could not believe how easily I could access all the sensitive information. I needed no password - just access to the profile. This profile will be saved on any computer that I have used to log into Firefox. Anyone with access to those computers could easily repeat what I was able to do. This is a serious secuirty flaw and I simply can't believe I was able to do this!!!!!

My blog has started displaying the message, "Firefox can't open this page". The message also says, "To protect your security, accounts.google.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window." But opening it in a new window didn't work. I tried clearing the cache, and pasting the link into a new open tab, but neither helps. I tried opening it in Safari, and that works fine, so this seems to be a Firefox problem. Any suggestion?

Dear Mozilla Firefox Support Team, I hope this email finds you well. I am writing to seek assistance regarding an issue we have been facing with Firefox. After some days of usage, Firefox prompts us to create a new profile, and the browser does not function as expected unless we do so. Here are the details: • We have installed the latest version of Mozilla Firefox several times (2-3 times). • We have also created new profiles, but the issue persists. • Despite these efforts, the error to create a new profile continues to reoccur. Could you kindly assist us in resolving this issue? Any guidance or troubleshooting steps would be greatly appreciated.

I have been using Firefox for years. Currently using 131.0.2 on Windows 10 Pro. Never had a problem with Bitwarden auto filling useernames and passwords to login to a website. Now I have to copy and paste each one. I appreciate using Firefox but this new incompatibility with Bitwarden is a deal breaker. I've tried going thru the menus and help forums and have found nothing to allow Bitwarden to auto fill passwords. I'll move everything over to Microsoft Edge where Bitwarden auto fills the same way Firefox has done until recently.

I want to disable 2fa. I FINALLY was able to find authentication codes (10 digit) and am able to sign in to support. I simply want to sign in and sync (after upgrading OS and reinstalling Firefox). I kept running in to issues signing in because it wanted a six digit authorization from a auth app which I did not have set up

suddenly the background video which has always played on my website's landing page no longer plays when accessing the site using Firefox. It works on Safari and works on my iphone and ipad. This happened suddenly and without making any changes

Hello, how can I remove or hide "List all tabs" btn?

Set "browser.tabs.tabmanager.enabled" as "false" stopped working for me after update to version 131.0. Hiding the btn before version 131.0 was not a problem.

I saw in release notes that "List all tabs" got some changes. link

Hi, In a nutshell, I need to have the Bookmarks Sidebar remain PERMANENTLY on the left side of my Firefox page. After an update, it now disappears if I change pages, and must be manually reinstalled on the new page.

I've been a Mozilla Firefox user since Mozilla Firefox was born. I currently use Linux 24.04 Desktop and Windows 11. This problem exists on both platforms: I've always kept my bookmarks displayed in a vertical column on the left side of the screen. I will call this a Sidebar. Whenever I brought up a new page, my bookmarks were automatically there to greet me in my Sidebar. Always. Now my Sidebar is gone. It seems to have been replaced by the Toolbar, which appears horizontally across the top of the screen, and it is awful.

I've tried very hard to restore the old way of doing things... I've spent several hours reading the solutions offered to countless numbers of people who have experienced the same problem. I've poured through the Firefox manuals. Nothing works. I've always been able to make things work in Firefox. But not this time.

The closest I've come is Ctrl-B. And of course my trusty "Book" icon in the top tray will also bring up the Sidebar when I go to a new page and click it.. But the problem is that I have to do this EVERY SINGLE TIME I go to a new page.

So here I am, begging for help. Please, please don't tell me to go again to the Settings Help Menu and press the "bookmarks" button, and follow the instructions . I've gone down an eternity of empty roads doing that. I'm not saying the solution isn't there, but if it is, it is hidden in a serpentine maze that has always led me back to square one.

Just tell me:

Either 1: "We goofed. There's no way to fix it without asking you to go digging into system files and risking the life of your Firefox Browser. Our guys will do the repair and send it to you along with a future Firefox update. Be patient."

Or 2: "Here's how you can, at home, make the Sidebar appear vertically on the left side of each page, PERMANENTLY. All you have to do is follow these explicit instructions that are guaranteed to work..."

This does appear to be, at best, a very annoying problem for countless thousands of your faithful users. Please help.

Thank you!
