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.

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.

Can't import ".p12" certificate in Firefox in Fedora 40, it fail with the message "unknown error". I can open it with the built-in tools as well with the Gnome certificate manager. I did try as well a different certificate with the same result. Both I can import in Chromium, installed as Flatpak.

Hi! From some time now i have problem with GUI elements overlapping each other. It started with the window control buttons (that part, where you can close the window). Esthetics aside, it was not that big deal, so I just ignored it, but some time ago similar overlap appeared on address bar - so now I don't see what I'm writing. This is a big deal, now I can't really tell if I made a typo, I'm not able to correct it or I can't see if what I'm writing is mixed with original url, stuff like that.

I'm on Manjaro Linux and Firefox version is 127.0 (64 bits) I've tried to reinstall Firefox with different sources, like Flatpak for example, but the issues persists. Has anyone an idea how to fix this?

Firefox has long been my browser of choice on all platforms. I am switching from Windows to Linux and have recently found problems playing some videos on the Linux version of Foxfire. I don’t know if it’s a matter of having the right codec or something else. The videos play with Chromium on Linux and with Firefox on my Android smartphone. My Linux laptop is running version 128.0 of Firefox for Ubuntu version 24.0.0. Here are two offending links. https://www.youtube.com/watch?v=WkZuGil6U4w https://www.youtube.com/watch?v=HxVcDPtDnjM

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]

I'm trying to install Firefox for Chromebook using Flatpak (article https://mzl.la/3pbybGW)

But I am faced with choosing a ref. See attached image. I have no idea how to choose, or what this even means.

Can anyone provide me with guidance on this?

My device is a Google Pixelbook with the latest ChromeOS.

Thanks

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?

Hi

When a site sends a Web Push Notification to my browser, it flashes up at the top of the screen for 2 or 3 seconds and then is gone. Sometimes I'm busy with something else and once I see it, it's gone, or I just catch the first word or two.

How can I display the Web Push Notification again?

I'm running Firefox on Fedora Linux, if that matters.

Thanks!
