Hello!

I would like to develop an application that runs continuously, say, at a panel found in a kiosk. I am considering designing it as a webpage that runs locally through the browser but I would like to prevent the users from interacting with the OS or closing the tab and the browser. Is there a way to lock Firefox in full screen and hide the exit buttons? Alternatively, do you have another recommendation for development that is more appropriate, for instance a native app?

Thank you in advance for your help.

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

On Chrome this displays as expected:

But on Firefox the background colors are ignored:

How can I get Firefox to display the background colors?

i am using firefox developer edition version 126.0b3 (64-bit) on linux mint with an x11 desktop and for some reason the drag and drop breaks frequently.

i think i have figured out how i can consistently recreate the bug as well as sort of fix it temporarily.

i start with a newly launched browser. everything works fine. but then if i attempt to drag and drop something shortly after i drag and dropped something else and it did the little animation where it returns to its original position, i find that i cant drag and drop anything FROM firefox to anywhere else. and i also cannot rearrage tabs.

it seems to fix itself whenever I drag something from another program TO firefox successfully such as text into a textbox, or a .html file into the window to view it.

Hi,

I'm using FF on Fedora 39.

However Firefox does not remember any file associations. The MimeTypes.rdf file in the profile is missing and is also not created on restarting the browser.

In the options I've now set the configuration to "Ask whether to open or save files". Now I see a popup when clicking on a file however there is no checkbox with "remember this file associations" (or something similiar).

The integrated webcam (IMC Networks Integrated Camera, according to lsusb) on my linux laptop does not work in firefox (v124). It works in desktop apps (eg webcamoid), and chromium. I've checked the permissions (about:preferences#privacy), and that is not the problem. about:support does not list the device in the input at all. I've tried using LD_PRELOAD=/usr/lib64/libv4l/libv4l1compat.so, but that has not helped. Does anyone have any suggestions?

Hello Good People,

I noticed that the snap version of Firefox had a lag issue when typing into input field. For example, when composing an email and wanting to use backspace to quickly delete a misspelled word, then backspace works slowly, stuttering and jittering. If I hold down a key in the input field it also lays the character down in a stuttery, slow way.

I tried reinstalling the system and that solved the issue. But it has returned again. Maybe it was an update. I also installed WINE and waybridge to get some windows plugins to work on my DAW. I don't know if that has affected it.

I also tried removing the snap version and installing firefox using the terminal but the problem persisted.

It's an annoying problem. Any advice appreciated.

Firefox can take screenshots of pages or screenshots of custom areas of pages.

According to the documentation, when we download the image, the filename should follow the pattern: Screen Shot yyy-mm-dd at hh.mm.ss.png. If I use the :screenshot at the console, the pattern works as documented.

But Firefox is using a different pattern when I choose Take Screenshot from the context menu. The pattern includes the page's title. Example: Screenshot 2024-04-14 at 18-35-16 General ‹ Settings ‹ Geomaster Lda — WordPress.png.

Since the page title can have non common filename characters, I have problems with such filenames. My uploads to MediaWiki fails with such filenames. I know I can report or improve MediaWiki, but my question here is quite simple.

Can I change the Firefox's default pattern for Take Screenshot's downloads?

When I watch a youtube video with chrome my cpu usage is 20-30% When I do the same with firefox my cpu usage is 50%

Running `about:support` and going into `webrender_compositor` I get the following errors under `env`: 1. Blocklisted by gfxInfo 2. Blocklisted; failure code 3. FEATURE_FAILURE_WEBRENDER_COMPOSITOR_DISABLED

I have set almost all these force renders = True and even granted gpu access to firefox flathub but still no difference in performance. I am asking now because I am just going in circles in the rabbit hole.

Hello

I want to use extension xpi's from a shared external folder over multiple Linux profiles. So i examined the profile folder and found extensions.json. Though i can't find any documentation to it's keys online.

There's "rootURI:" with a "jar:file://path/to/extension.xpi!/", so i tried just replacing the path with the shared one. Though i observed that just makes firefox replace the path with the current one. So i examined further and found the "location:" key with the default value "app-profile". So my guess is, there's other values for other usecases, right?

So, in summary, what i need is:

  • documentation to extensions.json keys or possible values to "location" key.
  • if that isn't intended/doesn't work, how i can achieve my goal otherwise.

And please don't suggest the sync feature, that doesn't work for my usecase.

Hello everyone,

Why some Wikipedia pages cannot activate reading mode under Debian 12 and Firefox ESR 115.9.1, for example this English Wikipedia page on Emmabuntüs does not allow reading mode to be activated while French, Spanish and German pages can ?

See our test video on this subject: http://share.emmabuntus.org/Accessibility/Firefox_mode_lecture_non_disponible_emmabuntus_en.mp4

Is there a utility to test pages compatible with reading mode?

Or otherwise in which Firefox log file to see if a page is compatible or not?

Thanks in advance for your help.

However, fcitx-mocz works everywhere else on my computer (i.e. terminal, thunderbird, other browsers, etc.).

hi,

When can we have firefox with translation set OFF by default?

I mean, it's pretty unfair that intelligent people have to keep turning off the dumb translator... all the time... We need a setting, openly available, in the Edit/Settings menu, where it belongs, an option to switch it off. In fact, when it first asks if we want a page translated, we need an option: never ask this again...

All we can see is "go under the hood of firefox, config:option, go into the about:config section where 10 of 10 million people will ever get... and there find your way to disable this horrible translator". When can we expect an option in the pop-up: "never ask me this question again"?

The translator in this offensive form has been around since 2023... I seems high time we didn't have to bother with this anymore...

Hello Good People,

I installed Firefox a few days ago and it was looking good. I don't like that icon in the top-left hand so I right clicked it and removed it. All was good. However, today there is a blank black space in the corner as if the icon was back (but without an actual icon). It's only a small thing but it bugs me. I want the tabs to be shifted all the way over to the left like they have been up to today. It's triggering my OCD. Anyway, any advice appreciated.
