Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

Download files (pdf, xml) don't open in application (acrobat, firefox) since 125.0.1 Firefox version from IBM Power server with Ubuntu :

The message is "Fichier non téléchargé - Risque de sécurité potentiel" that is "No downloaded file, potential security risk" :

When we download a pdf file from the server, the "choice box" allow to . open in the browser or . open in Acrobat or . download on my PC. The opening fails with this message. This is the problem. The download on my PC works and when I open the file from my PC it works also.

We need this function of opening a pdf or xml directly from a server IBM Power with Ubuntu. It was OK for several years until 125.0.1 Firefox version. We had no change on the IBM server.

Can you repair this problem quickly. My PC uses Windows 10

Thank you Patrice Castejon [removed phone#]

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

When trying to install any extensions on either the Mozilla Addons website or directly via the Extension settings, it fails to do so.

I've attached a screenshot of the Mozilla Addons website when it fails to install the extension. On some other addons that I've attempted in the past, it just shows the throbber forever.

I have checked the Multiprocess Browser Console and it says that it fails to move the file because it's locked (NS_ERROR_FILE_IS_LOCKED). I have also attached a screenshot of that.
