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.

The system continues to tell me that my original email address is the primary address. That address has been hacked and I need to remove it and replace it. I am then told I need to add a secondary address before I can change. I go into the area where this is done and when I press add it says that the new address is already there. How do I get rid of the hacked address and replace it with the new one (which Mozilla does actually recognize!)?

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.

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.

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)

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. [Child 8724, MediaDecoderStateMachine #1] WARNING: 7fdc1c636ee0 OpenCubeb() failed to init cubeb: file /build/firefox-kPTBHF/firefox-128.0+build2/dom/media/AudioStream.cpp:285

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.

I'm talking about how when you go to fill out a text input, it'll suggest that input next time you go to a similar field. Well, that system just saved my social security number as an input after I filled out a government form. I would like to turn this feature off now, and delete the history of it if I can. Is there a way I can do that?

I'd attach an example image of a different website, but the box goes away when trying to take a screenshot.
