If I change to a different tab (from Xfinity) and go back I am getting logged out and have to re log back in, even if I check the box "Remember Me" This does not happen with Edge, and seemed to happen from the latest update from Firefox on Oct 20th, 2026. Is this going to be the new normal

I started automating the organization of my Downloads folder and after moving to Firefox full time found out that every download creates two files. This is related to the Firefox creating an empty placeholder with the original file name and a .part temporary file.

What happens is that my folder automation moved the empty file to the final resting place while the download is being streamed into the .part temporary file. In the end I end up with two files: one with zero bytes and a secondary one original-filename-1.

I tried to fix this issue enabling the browser.download.start_downloads_in_tmp_dir setting, but it seems the flag is ignored in macOS 27 and Firefox 158. It still creates the two files in my Downloads folder and the behavior I described above keeps happening.

Is there a way to use a temporary directory or forcing Firefox to use one file only?

I have used Fire fox with https://www.lloydsbank.com/ for s few years without issue. This morning when I go to the website I select Log In > Personal and get the erro "403 Forbidden" this happen on my linux laptop and windows 11 pro pc

Brave browser on the linux pc work and I can log into the website successfully.

I have repeatedly removed/cleared browsing data for the specific site, made an exception for that site too but there is no change. This is obviously a firefox problem as the same error occurs on windows.

I have also disabled my extensions on the linux laptop firefox. My firefox version is 158.0.1 64 bit.

help would be very much appreciated. thank you

On `about:keyboard` I rebound 'Full Screen' from F11 to Ctrl+Shift+F. This works for opening full screen, but it doesn't work for exiting full screen; I have to use F11 to exit.

I can't find any other setting for exiting full screen mode, so I assume this is simply an oversight by the devs, but if not, I'd appreciate help figuring out how to rebind exiting full screen as well.

ive just downloaded firefox and its giving me performance issues I play gta 5 all day with my chrome tabs open maybe more then 5 sometimes more then 8 and When I had more then 4 or 5 tabs my gta 5 started to lag when i opened my task manager i see that Firefox is using more then my Game.

Lately Firefox keeps crashing on my iPhone, iOS 26.6.2

When I re-open it, all my open tabs reappear but all data entries on the webpage I was last on are gone.

This is only happening on my iPhone, not other devices.

Hello,

I have a subscription to Mozilla VPN that I no longer use. I signed up with a proton mail address to which I no longer have access (no recovery information). I would like to cancel my subscription.

I have my bank statements showing that i pay 9.99 to Mozilla every month.

What can I do?

Thanks in advance!

I use the DeepL translation app in Firefox on my Mac Mini M4 (OS 27.0.1). The app has an audio button to hear the written translation. When I use this feature, there's a loud pop at the end of the translation. This doesn't happen in the standalone app on my Mac. There are no audio/video devices connected to my Mac; the audio is from the Mini. All systems are updated.

So MANY times I see this warning!......

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

Then I have to close everything out and start allover. I have cleared my browsing history, cleared all cookies and everything else possible,turned off my desktop, unplugged it and pressed the power button just to browse a few more minutes before that message pops up again. I have even goe so far as to unplug my modem, and router for 20 minutes. My desktop is hard wired to the internet.

Updated Firefox browser for desktop on Mac to 158.0 on 10/15/26

On 10/14/26 using previous Firefox version 157.0 on Amazon.com Prime Video section, pages would load properly and videos could be played properly.

10/15/26 using updated version on Amazon.com Prime Video section, page would initially load properly only to later freeze. Videos could not be played. And freezing could not be corrected unless closing the tab on the browser.

10/15/26 using Safari browser on Amazon.com Prime video section, pages loaded properly and videos played properly.

Clearing cache and site data on updated version of Firefox did not have any effect. Pages continued to freeze and videos unplayable when starting over and navigating to the relevant pages.

Steps to reproduce:

go to amazon.com login to account go to prime video page

expected results video selection appears and user can select and play videos

actual result video selection appear but freezes after a second or two,. videos cannot be played

Repro rate 5/5

Environment Variables Firefox 158.0 Mac OS GoldenGate 27.0.1

Other information Other amazon pages like whole foods and home page and Subscribe & save not affected Just Prime Video page affected

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 sometimes experience issues when accessing web-based email services through Firefox and want to understand whether browser settings or extensions could affect them. When using a bulk email service provider such as iDealSMTP, what Firefox settings should users check to troubleshoot email-related issues? Have you experienced similar problems when accessing a bulk email service provider through Firefox?

This is the 2nd issue arising from a v158.0.1 update disaster. FF won't print a page: it seems to start, and then blanks the screen, returns to windows wallpaper. the printer stirs but prints nothing. The printer tested OK from the windows test page. As recommended in the fix suggestions, I tried the clear printer option in troubleshooting, but that does not work. How do I fix this??

Using windows10 on the ESU program on this machine.
