I am using Pop OS, which is based off of Ubuntu.

Somehow I did something, and it made the icon disappear for Firefox. I figured I could easily search the internet and find a simple solution.

I temporarily fixed it last night, but here it is missing again.

I could upload a picture, but I don't see what difference that would make. The dock at the bottom has a spot for firefox, but no icon, literally an empty spot, In the application menu it is a blank spot with Firefox worded underneath.

I have uninstalled, reinstalled, purged, deleted the application data in my user folder..

Just annoying. not a huge problem.

I was following this article https://support.mozilla.org/en-US/kb/run-firefox-chromeos

Installed flatpak and repositories but when I try to use flatpak to install firefox I get "No remote refs found similar to ‘firefox’".

I have tried following a few other ways to get it installed, such as using sudo and using sudo su but that has not worked at all.

I followed to flatpak quick setup on Chromebook guide that is linked in the above help article and created the nested containers in crosh as well.

below is what happens if I go to flathub and copy-paste their recommended command to install firefox.

Remote ‘flathub’ found in multiple installations:

  1) system
  2) user

Which do you want to use (0 to abort)? [0-2]: 2 error: Nothing matches org.mozilla.firefox in remote flathub

Hello! Just installed Ubuntu 20.04.4 on my laptop and now find that I'm not able to watch some YouTube videos on Firefox 97. It seems mainly just live streams that I can't watch. When I go to one it shows "Your browser can't play this video...Learn more" in the video window. Clicking Learn More takes me to a page that doesn't explain what the problem is. Any idea what the fix might be? The same videos play just fine on other devices on my network. Any help would be greatly appreciated.

Firefox breaks my desktop environment's scrollbar style and (gradient) color and in version 98+ refuses css to approximate it

I work on kubuntu 20.04 with plasma 5.18.8 desktop environment. I have a QtCurve-based custom application style, which I almost match with css for GTK apps. Firefox has to be an exception by itself! Not only that, but it changes my ability to customize its interface, from time to time and even changes access to such ability, on some updates.

My scrollbar customizations in userChrome.css and userContent.css do not work any more (other CSS changes still work, for menu/addressbar/tabbar/bookmarksbar orderint and tab styling). I had to resort to settings in user.js file, to get a 20px width scrollbar, suitable for my big screen, but... it gets very wide when I increase the focus, on some webpages and becomes very ugly! Furthermore, I cannot make sense of the proper use of "ui.themedScrollbar*" settings and the scrollbar and its slider result in the same color. These are my settings in user.js:

user_pref("widget.content.gtk-theme-override", "backwater"); user_pref("widget.non-native-theme.enabled", false); // Use GTK-3.0 gtk.css: set to false user_pref("toolkit.legacyUserProfileCustomizations.stylesheets", true); // Use userChrome.css & userContent.css: set to true user_pref("widget.gtk.alt-theme.scrollbar_active", true); user_pref("widget.non-native-theme.scrollbar.size.override", 20); // If nothing else works, fix scrollbar width to 20px user_pref("widget.non-native-theme.gtk.scrollbar.round-thumb", false); user_pref("widget.non-native-theme.gtk.scrollbar.thumb-size", 1.0); // originally 0.75 user_pref("widget.non-native-theme.gtk.scrollbar.allow-buttons", true); // it was true, anyway... user_pref("layout.css.cached-scrollbar-styles.enabled", false); user_pref("layout.css.color-mix.enabled", true); user_pref("widget.non-native-theme.scrollbar.style", 4); // wide scrollbar theme: set to 4 user_pref("ui.themedScrollbar", "#bad1f5"); user_pref("ui.themedScrollbarInactive", "#668cc4"); user_pref("ui.themedScrollbarThumb", "#e4e4e4"); user_pref("ui.themedScrollbarThumbHover", "#e4e4e4"); user_pref("ui.themedScrollbarThumbActive", "#668cc4"); user_pref("ui.themedScrollbarThumbInactive", "#bad1f5"); user_pref("browser.dom.window.dump.enabled", false); user_pref("extensions.ui.sitepermission.hidden", false); user_pref("fission.experiment.max-origins.qualified", true);

Either with the "ui.themedScrollbar*" settings or without them (and cleared from the prefs.js file), the scrollbar and its slider result in the same color, unless I (tryingly) click on some place on the scrollbar outside its slider; then I can see the slider, _only_ for the duration of the mouse-down event (which causes up or down page-hight scrolling).

The default, very thin scrollbar, as well as my modified wide scrollbar with invisible slider are both useless to me! I have even tried fx-autoconfig (https://github.com/MrOtherGuy/fx-autoconfig) to make the scrollbar CSS work, but no result. At this point, I am considering switching to another browser, despite the trust I have to mozilla, for my data and privacy.

Dear Mozilla Support,

After some update (I think from 89.0.0 version of Mozilla Firefox - this version with new looks of tabs) I notice flickering on the tab when I loading website or refresh website. This looks very strange. Like I said I dindn't notice any issue with flickering on previous Mozilla Firefox versions. Only with these new versions with new look of the tabs. I didn't remember if it was 89.0.0 version or 90.0.0 version. I don't know if it is problem with the machine but I didn't notice this issue on another computer with 90.0.2 Firefox version but with Windows 10 OS. I also noticed this issue with Firefox 90.0.0.2 with Windows 7 OS on another computer so I don't know if this is problem with two computers or Firefox itself. Can you help me?

Yours faithfully, Piotr

Does anyone know how to configure Firefox to stop the annoying google log-in pop-up? I've seen others ask the same question, but I have not seen any functional answers. I've never had a google account, for anything. I don't get the pop-up with other browsers, like Falcon or Brave. It's just a problem on Firefox. I appreciate you help!

Firefox needs a limit on memory usage. I was developing a tiny web page on Linux (PopOS) and accidentally created an endless loop in Javascript that ate memory (by growing an array). My entire OS became inoperable and had to be hard-rebooted. I was surprised this could happen due to Javascript (a sandboxed browser language), running in a web page (a sandboxed app) running in a Firefox browser that is supposed to protect users from the world wild web. One errant line of legal Javascript in HTML should not equate to a denial-of-service attack.

A sensible approach would be similar to the nice warning given when a script takes too much CPU, offering the user the choice to continue or stop the script when a tab exceeds some reasonable size: a fixed MB size, or say 10% of real RAM memory.

Ideally there should also be some hard limit calculated by Firefox according to the machine's available memory and Firefox's reasonable percentage of it. For example, maybe limit Firefox (all tabs combined) to 50% or maybe 75% of real memory, so that the O/S has a reasonable chance to remain operational so that a bad tab can be closed. Otherwise, Firefox could cause the O/S to lock up, resulting in data loss if there are tabs or other apps outside of Firefox that have unsaved changes.

Thanks for your consideration!

How to have uninterruptible full screen

There are some browser games that are best played full screen, but I can't seem to find a way to keep the "helpful" menu from popping up over my game when the mouse hits the top edge of the screen. The best I can do is not play full screen, and detach the tab of my game to minimize the amount of tabs visible (and clickable) but there are still these "landmines" on the screen that actively sabotage playing the game without having the handicap of firefox taking over and messing with the screen.

Is there any way to completely disable the popups from a fullscreen mode, show no toolbars, tabs, or anything else (except when exiting fullscreen mode via the keyboard.) I want the mouse to have no interaction with changing the display except for the game itself.

Playing http://slither.io is a good example of what I'm talking about.

Thanks!

Firefox worked perfectly, but since a few days I can't download anything. I'm using Mozilla Firefox snap for Ubuntu 22.04, version 110.0.1 (64 bits) canonical-002 - 1.0 With Chrome everything works perfectly so I assume it's a problem from Firefox.

When I open a PDF, a MP3 or any file, the "save" option doesn't display anything. Usually it opened a dialog where I could choose the folder where I wanted to download the file, but now I have nothing.

I have only 4 extensions: - adblocker ultimate - duckduckgo privacy essentials - vuejs dev tools - zotero connector

I always had them and I never encountered any problem.

Having just upgraded my Debian 9 machine to Mint 20, this has updated my firefox browser.

Everything was going fine until I came across the problem where by all image downloads are saved as webp images, a format that my favourite image editing software cannot handle.

This is a bit of a pain and has made me start looking at alternative web browsers.

Just thought you should know how simple things can cause a loss of support.

Firefox 93.0 64bit Linux Mint 1.0

When I close (X) the window, my session is not restored. I have checked all the settings and verified that they are set correctly. Then, I found that when I tried to quit the program via File menu, it says that I have two windows and three tabs open, yet I only have on window/one tab open. I can not find this other window... What does this mean? Have tried refreshing the app, safe mode, and disabling the extensions that I use.

Hi all :)

From a fresh Linux Debian Bullseye I try to connect to a local machine with Firefox (v97 64-bits) by its hostname (avahi server with default domain "local") with the port 6180 bound to a remote web service port (61 is the distant machine IP and 80 is the forwarded port).

When I want to open this URL : http://bionic.local:6180/ FF displays "We can't find this site ... Unable to connect to server at bionic.local ... check your network connection and firewall"

BUT ping bionic.local works perfectly and resolve the good IP address from the Chromium navigator the same URL works without a problem, I can open the distant web site.

This workaround works : add a static resolution in the /etc/hosts file : 192.168.0.71 bionic bionic.local => so FF works in the expected way for now ! But as I said this a workaround and a bad solution.

I supposed too the port was blocked because I accessed an unusual port. So I tried this without success.

How the hell make that FF v97 allows me to use an unusual port ? Or is it bound to the domain "local" which is no more accepted by FF ?

Thank you in advance for your help. With adelphity, lnj
