Using FF 115.12.0esr from openSuse 15.5. Get responses from various web sites that the browser needs an update, that it is no longer supported, etc. Some sites block me out. Another site just now reported the version of my FF is 102--so no wonder it has problems. How can I change the version number that web sites see to reflect the actual update level? Sample message: EDAS at delta for 108.51.160.90 (Wed, 10 Jul 2024 16:34:44 -0400 EDT) [User 1776561 using Linux:Firefox 102.0 0.141/0.569 s]

Hi,

just for understanding:

Why can the Firefox source code (view-source) of a website be nearly three times the size compared with Chrome/Opera or when I save the Firefox source code marked and copied and then pasted and saved via an editor?

Example: Firefox 546,6 KiB Chrome/Opera 204,3 KiB via Editor 204,3 KiB (marked and copied Firefox source code)

Hi,

I am working on a website- one page uses websockets for data sync, activated with a button - and the socket takes a long time to actually connect (to locahost). During that time, an error pops into console- several of the same:

The connection to [url] was interrupted while the page was loading.

I found several bug reports in various places - most say to close the socket on page unload. I already have that implemented, and checking network dev tab shows all sockets are closed when the errors occur, and they also appear when tested in a whole new window. Also tested on chromium- no issues there.

Any help?

Why I can't login to outlook.office.com (Microsoft 365) with passkeys when I use Firefox (newest 128) in Linux? It doesn't offer me to use passkeys to login when I go there.

I can login with passkeys in Firefox when I use Windows 11 or Google Chrome in Linux.

I can install firefox in a 20.04 ubuntu image however I can't get the sound to come out to the host. I think it is because of these messages: oot@lnx01:/# firefox libEGL warning: DRI2: failed to authenticate ATTENTION: default value of option mesa_glthread overridden by environment.

I am using the tainted nvidia driver on my host. Has anyone got this to work? I messed around by adding various mesa drivers to the image with no fix. Any suggestions? I am using the ppa version of firefox in the container.

This is super frustrating. How to use Firefox for development purposes? There should be an option to add exceptions. I even went to settings and added an exception manually to no avail.

I'm going often through pain to use firefox for everything but then there must be a reasonable way to achieve the goals.

Please tell me there is a way to workaround this easily without compromising security of other sites that are being visited.

P.S. I can open same site with adding an exception on chrome.

Hello everyone, I am experiencing this issue since - I suppose - Firefox Sync existed. My main machine has - like any other machine I own - Firefox always up to date and a set of plugins like No-Script, an ad-blocker, a theme, GUI icon disposition and whatnot. When I install Firefox on a new device or machine and then proceed to sync them, I lost the theme across all my synced devices, ALL of the registered sites I have trained No-Script and the adblocker not to block and my GUI settings. In short every new machine with a fresh install and sync of Firefox will wipe and overwrite to its defaults any synced custom configuration I have. Is there a solution for this?

Thank you.

I use my laptop with a connected AOC ultrawide monitor as primary screen and I don’t mirror laptop screen. My system is running KDE NEON, everything updated. I have an issue when watching video in Firefox. As long as I’m watching a video on a website it works fine, but when I change the video to fullscreen the monitor just show a black screen without turning off. I tried to activate the laptop screen and it show the video I’m running in fullscreen, which should run on external monitor. So my question is, why does Firefox move the fullscreen video to the laptop screen when I don´t mirror the laptop screen to the primary screen? Hope someone can help me out.

Please advise how to disable automatic updates on Firefox running on Linux Kubuntu. Solutions posted on mozilla.org do not work because stated disable options are not available(see screenshot). I have set app.auto.update to false in about:config but this does not disable updates. I have been repeatedly advised not to disable updates so I am aware of the so called risk. I am very tired of every update breaking a reliable browser and having to repair/fix/workaround each and every time. Please provide a viable solution.
