Firefox created a folder "Old Firefox data" on my desktop which is impossible to delete. I am getting an error "Access denied" even when trying to delete it as administrator. How can I delete this folder?

Win 11 stopped working on my Lenoovo Yoga due to bitlocker key requirement that does not exist I'm in the process of installing Ubuntu during the installation something went wrong "system program problem detected" which stopped the installation

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?

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

Got this error message on recent update and now Firefox doesn't work at all. Platform Version '131.0.3' is not compatible with minversion >= 131.0.2 maxversion <= 131.0.2

When I started up Windows 11 on my new laptop, I had to connect to the web via Edge to be able to install Firefox. I foolishly went on to install Firefox via Microsoft Store. I have now installed Firefox from the Mozilla website via the Microsoft Store version, but I cannot uninstall the Microsoft Store version. I don't have access to the folder where it is installed even though I log on as an administrator.

Hello, could you please let me know if updating Firefox as suggested (version 128) will be compatible with my iMac OS X Version 10.9.5. Thank you very much. Kind regards AS.

Hello:

When I signed into my computer this morning, a pop-up asked me if I wanted Firefox to update. I let it do that, and then a pop-up came up letting choose among some photos and art for a desktop background. It even let me upload a photo of mine. I chose one of yours, now I can't change to any other photo I have on my computer. Please help.

Thank you,

Cynthia M.

Running Firefox on macOS Sequoia 15.0. Afternoon of Tuesday, 8 October, Firefox abruptly ceased loading any pages. I eventually learned of the malware incident and downloaded Firefox 131.0.2 last night and overwrote the existing file. It worked for a brief moment, then also ceased functioning. Have downloaded 131.0.2 several times now, with no further success. Currently dead in the water with Firefox, and stuck with Safari. :(

I am not sure what to do first. I already paid for the VPN subscription. I reinstalled Mozzilla VPN but have not yet put the sudo lines in that are listed in the help on Firefox. Can you send me an email with instructions and any special sudo lines I need to intall so I do not get charged a second time. I heve the recovery code. I am new to Mint. Windows 11 started knocking out my hardware with power surges. Had to come from the operating system itself since the machine is hooked to a power backup that smoothes the current out. Converted everything to Linux. Like it. Life can be cruel... LOL Thanks so much for the effort. [edited] landline, but best bet is email. [edited phone# and email from community support forum]

Hello all,

During clean-up of my laptop I noticed 31 language package files in C:\ProgramData\O949. File names look like: langpack-en-US@firefox.mozilla.org, and they all originate from 23-Jan-2017 so I guess they're very old files which might be relevant anymore. As these 10,058 files occupy 56 MB I'd like to remove them from my laptop.

Does anybody know if such task is wise, not harming current running FF v131.0.3?

I have a macbook air laptop (late 2010) and have been using the latest version of Firefox browser for browsing. It's one of the few browsers still available. Google is popping up with the message that my browser is no longer supported. Do you have any suggestions about a browser that may work (other than a new computer please)? Will Firefox be coming up with a new extended version that will work? Thanks!

Hi James Your reply does not answer my question - "Could you please advise a work-around to allow me to continue to use Firefox V 94.0.1 reliably after 25 March 2025". Thank you. Also FYI, I indicated that I was continuing to use Firefox V 94.0.1 (64-bit) on Windows 7 Professional. This is because all versions later than 94.0.1 modified settings which had to be reset after an update. This was not necessary up to and including V 94.0.1 Cheers Graham Garden
