I have a APC UPS and the software provides status information on localhost 6547. For the last 9 months since I got this UPS this has not ever been an issue, but for the last three days I keep getting an error message when the APC software tries to open a tab in Firefox. The error message is "Firefox spotted a potentially serious security issue with localhost:6547".

How do I make an exception for the APC software so I don't have to authorize Firefox to open the tab every time I want to look at status information for the APC UPS now?

I hope the firefox desktop browser, supports to protect the profile from getting access by other person, who uses the PC. Whole disk encryption is too heavy, so I want to protect the profile on browser side since you already support master password to protect the 'Password'.

Feature request: For a profile with firefox account loggined. Prompt to re-type the password to open the browser, or you can also lock the browser manually until re-type the password. Then able to access the bookmarks and history, so as the session tabs.

Recently Firefox has stopped recognizing website exceptions entered into pop-up blocker manage exceptions. I have deleted all websites and reentered a couple but none are being recognized. therefore these websites are blocked to me. One is https://www.foxnews.com/. This problem started after the last Firefox update.

My monitor is repeatedly getting small rectangular pop-up windows, each of which says "Mozilla Firefox". They contain messages like "Trojan virus detected!" or "Attention! Click here to remove it!" What can I do to stop these intrusive small windows from popping up on my screen?

Hi I've used Firefox for decades. Now, since updating to Firefox 158.0 (aarch64) on my Mac Studio and a Macbook Pro, I’ve been unable to open my usual banking websites. They still work in Safari on the same Mac & Macbook Pro and through the banks’ iPhone apps.

Have any recent Firefox security or privacy changes affected banking websites? Which settings should I check, and how can I safely allow these sites without disabling protection for all websites?

Hello,

I'm building custom firmware for a Makerdiary nRF52840 USB dongle using GitHub Actions.

When I tried downloading the generated ZIP file, Firefox blocked it with the warning: "This file contains a virus or malware."

I removed the blocked download rather than overriding Firefox's protection.

The ZIP contains custom `.uf2` firmware for an embedded USB device. The GitHub Actions build passed its validation checks, and an independent ClamAV scan of the original firmware reported 0 infected files. I subsequently built and scanned an updated version, which also passed.

Original blocked build: https://github.com/flips96-art/hid-remapper/actions/runs/39094413639

Latest build: https://github.com/flips96-art/hid-remapper/actions/runs/39096517313

Latest antivirus scan: https://github.com/flips96-art/hid-remapper/actions/runs/39096868117

I understand that a clean ClamAV scan does not guarantee the file is safe.

Could someone help me determine why Firefox classified this download as malware and explain how to submit it for a possible false-positive review without disabling Firefox's security protections?

Thank you!

When I am using Firefox, which has been my primary web browser for years, I find that in the past month, in addition to opening the link that I want, a separate window with information on Alaska cruises or free shipping webpages, which I am not interested in opens. Is this happening to others, and if so, are steps being made to correct this problem. I am collecting some of the extraneous links that have been popping up,

I am using FF 158 on Win11

I noticed that apps after login are being restored with my previous session even if i close the browser and restart the browser!

ways to reproduce the problem: - Login to an app - Exit the browser, ensure the Firefox.exe is not running using Task Manager - Restart the browser and go to the same app URL. - At this point I expect the app to prompt for a password again (It does prompt for a login on Chrome and other browsers including FF 154) however on FF 158 the session is still active!

I have checked the settings in FF 158 and disabled the restore Tabs option on startup however the bug still exists.

This is a serious security issue. Kindly investigate and address

Regards Sanjay
