Fihaonambe Fanampiana Firefox

We have a noticed a very strange behaviour with the latest FireFox (126). One of our webpage is behaving differently across our Integration and production environment. Both env are running identical code and similar network stack the only difference we have noticed so far is for our Integration env Firefox is sending the different user-agent string than for production.

Steps to reproduce: 1. Open https://integration4-view.publitas.com/automation-int4/reader-happy-path/page/1

2. Go to console and view navigator.userAgent the user-agent string will be:

    "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:126.0) Gecko/20100101 Firefox/126.0" 

3. Now open the same content on production -> https://view.publitas.com/automation-prod/reader-happy-path/page/1

4. Go to console and view navigator.userAgent the user-agent string will be:

   "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) FxQuantum/126.0 AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.5060.71 Safari/537.36" 

Our website changes behaviour based on which browser it is and based on second string our backend interprets the browser as chrome instead of Firefox.

If I change privacy.resistFingerprinting to True then the user-agent string is sent correctly.

Can you please help us identify what changed in the latest version that is causing this behaviour.

Version: 126 (64 bit) Test on Windows 11 and Mac OSX

In release 126.0 (64-bit) in Windows, persist logs in developer tools is not working for me. I've tried selecting and deselecting all the combinations in both settings areas in the split console, quitting the browser in between. Is there a new place to set this?

whenever I am filling out an online form that requires basic info, Firefox prompts the common info that I have input in the past via the Auto-fill feature. Whenever I click on the suggested information, a new settings tab opens and switches my screen view to that tab. This didn't happen prior to the most recent update and has made filling out various forms extremely tedious and frustrating.

I found a file that has an IP address at the top of it. And the IP address is from China. recently my email address showed up on dark web. Do you think It could be connected. and is hack?

Almost consistently every day and often multiple times a day, Firefox will freeze up, unable to load new tabs, and sometimes will display a message that the browser has updated and requires a restart. Upon restart (when fozen), I'm prompted to create a new profile because I'm using an 'older version of Firefox'. After creating a new profile, I'm able to update the browser and switch back to my original profile.

Although this is a relatively easy fix, Firefox requiring me to restart my browser without being able to do anything else is disruptive alone, but not even completing the auto updates, crashing, and requiring me to do a workaround just to keep using the browser is driving me back to a more stable browser.

I don't remember updates requiring a restart before, or maybe they didn't happen enough to cause issues in my workflow.

I have tried using the 'restore' feature in the uninstaller hoping that it might resolve the issue with no results, but I haven't found any reasonable other options with my searches online.

Hello there, for past few days I'm having issues mainly on Twitch.tv - the streams do work fine, but whole website is displayed as text - Avatars, emotes, badges are displaying as text, or don't display at all, I'm attaching screenshots as examples. What I've tried - restarting PC, router, full re-install of Firefox, disabling all add-ons and uinstalling them (7tv and FFZ), private mode, troubleshooting mode, creating a new profile in Firefox, checked firewall settings, checked AV settings and did multiple scans - nothing was found, tried changing Firefox security Settings, also cleared cache and cookies.

I think that's everything - I was doing everything that was in the article: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems

Regarding other websites - this is completely random, mail works, some websites also do, but on some it gets stuck, like for example when I have to do a 2FA somewhere and get a pop-up window to click "login" or type a code, it just gets stuck and nothing shows up.

Not sure if this helps, but exactly same issues appear on different browsers - Chrome, Edge, but only on PC. I tried Firefox on mobile and it worked just fine.

If I can provide more details please let me know, I did attach the "Troubleshooting Information" so hopefully this also helps.

Thank you in advance!
