Firefox Support Forum

On Firefox 90 on Ubuntu 20.04, when a site asks for camera and microphone permissions, it’s not possible to select any device anymore. It just shows the default camera and the default microphone.

Earlier Firefox releases used to show a selection list for the camera and also another one for the microphone.

My default camera is the one built into the laptop and I would like to use an external one that has adequate picture quality.

Can you please help selecting a camera with the new Firefox?

After I have started the computer and have opened the Firefox Developer Edition, there is no website content visible - everything is transparent. Links are clickable and context menu opens up, but the content is just transparent (screenshot attached).

When I close & repone the firefox, then usually on 5th to 10th attempt everything starts working until next reboot.

Firefox(Default edition v94.0) is working just fine with no problems on same machine.

When I first noticed this, version was 95.0b3. Now I'm on 95.0b12.

OS is Xubuntu 21.10 and hardware is HP ZBook Power G8 - i5-11400H, Nvida Quadro T600.

I've already tried: 1) opening on safe mode, 2) reinstalling using Ubuntu's "umake" commant line tool, 3) reinstalled by downloading it from https://download.mozilla.org/?product=firefox-devedition-latest-ssl&os=linux64&lang=en-US and copying the files, 4) opening computer using both Nvida's and Intel's built-in gpu

but nothing have worked so far - still the issue persists.

Is there anything else I should try?

Thanks!

Using Firefox 94.0

The objective is to change the tags of large numbers of bookmarks. This is to organize existing bookmarks under new categories that help in finding them more easily.

Until some time ago, I used the Library (Ctrl + Shift + O) to first select a batch of bookmarks (whether or not filtered after an existing tag or another criterion); and typed the new tag in the field Tags: at the bottom of the Library dialogue window. If I had to change the tag, I simply wrote the new one; the old one was replaced. If I had to add a tag, I could repeat the old tag and add the new one.

Now, instead, my new tag is appended to each and every bookmark in the batch. This makes it impossible to delete the old tags, unless you do it one at a time. Both doing and undoing become unwieldy when you have tens or hundreds of bookmarks. Also, it defeats the purpose of streamlining, because the number of tags grows.

So, there is a difference in behavior between editing the tag of a single bookmark and the tag of a batch of bookmark. Is this intended? If so, how to work around that? If not, I presume this is bug.

I know that a extension, ones that add functionality can be installed from a local file on my PC but i need to know how to extract the extension and store it on my home PC ? I know there are scripts available but i don`t remember where.

I've browsed through a dozen of posts now and so far got my homepage to show me my local file. The problem is that I want this local file to also show when I open a new tab (Ctrl+T).

I've configured an autoconfig based on another post I read, currently have this:

In my autoconfig.cfg: // first line is a comment var {classes:Cc,interfaces:Ci,utils:Cu} = Components; var newTabURL = "path_to_my_file.html"; aboutNewTabService = Cc["@mozilla.org/browser/aboutnewtab-service;1"].getService(Ci.nsIAboutNewTabService); aboutNewTabService.newTabURL = newTabURL;

In my autoconfig.js: // pref("general.config.filename", "autoconfig.cfg"); pref("general.config.obscure_value", 0); //pref("general.config.sandbox_enabled", false);

I have the last line commented because it worked for the poster, but it gives me an error that firefox couldn't load my autoconfig and that I should contact my sysadmin, lol. Other than that error message, it worked the same as it does now after I closed the popup.

If possible I don't want to use any extensions for this.

A lot of webGL apps are very low framerate (and lie about their framecounts), for example: https://webglsamples.org/blob/blob.html This runs smoothly at 60 fps in chromium, but in firefox it behaves badly. The fps counter flickers as either 53 or 80, but in reality it is maybe 15fps or lower and very stuttery. The resolution, number of blobs, or size of the window does not change anything.

• If I enter Troubleshooting Mode, it all returns to working order. The FPS is fixed

I have tried disabling ALL extensions, changing to the default theme, disabling hardware acceleration, deleting cache+cookies+history

I installed firefox developer edition and checked it there, and it was at 60 fps, until I logged into Sync, when it then dropped.

I use KDE manjaro linux and have hardware that is definitely good enough to run the content at high framerates normally (everything works perfect in chromium)

Every time I play this online game at the site, Wormax.io, it will lag and/or crash the tab after a few minutes of playing. Occasionally, the site will take a very long time to load.

Here's my crash report: bp-4fd287ff-c2e1-4168-8e9d-ac1950211202

I expect that each page / tab in firefox is placed in its own thread.

However, I experience that when one page gets stuck .. javascript is caught in a wait loop .. that this affects other pages.

Is there something in FireFox that I can change to insure that each page is in it's own thread, and doesn't affect another page's performance?

Hello,

I have a new Cisco Webex Desk Camera that it's not working with Firefox (Flatpak on Fedora Silverblue 35).

lsusb: Bus 006 Device 004: ID 05a6:0023 Cisco Systems, Inc. Cisco Webex Desk Camera

https://mozilla.github.io/webrtc-landing/gum_test.html shows two cameras "Video Capture 4" and "Video Capture 5", none of them work, the page shows an error message: "AbortError: Starting videoinput failed".

The same website works in Chromium (also a Flatpak), which only sees "Video Capture 4 (05a6:0023)". "OBS Studio" is also able to use the camera. "Video Capture 5" is not available in Chromium and freezes the image in OBS Studio. I believe Video Capture 5 is the IR camera that is used in Windows Hello.

Would you be able to help me to get this camera supported, please?

For my work, I need to paste a lot of links into text (on a website which is probably somewhat poorly programmed), and when I select some text and hit ctrl+k to create a hyperlink, Firefox doesn't recognize that it's a text box and "takes over" the ctrl+k function, focusing on the search/address bar instead of allowing me to insert the link. (The reason I blame the website is that other websites, like Jira, work fine for this)

Is there a way to disable the ctrl+k functionality in firefox? I've seen a couple old threads on disabling various shortcut keys but I don't know what the "Focus Search bar" key would be called in either the Browser Console or configs.

Thank you!!

I did not like installing apps from firefox add-ons but loved installing applications from firefox marketplace when it was there back then. It made me feel productive as it was the app store of an OS ,which was also there back then. But why was it discontinued? If there is any reason, please reply and If possible, please try recreating it. Here are the new firefox marketplace icons I suggest which I got from the web archive. Each icon is larger than the previous one. And if possible, please work on firefox OS too.

Hi,

I'm using Firefox ESR 78.15 with a slightly modified Arkenfox user.js

I keep getting two "Unknown Collection" messages in the console after startup.

The first one reads Unknown Collection "main/messaging-experiments" in the headline, while the following text is shown in the drop down menu: "UnknownCollectionError resource://services-settings/RemoteSettingsClient.jsm:155 sync resource://services-settings/RemoteSettingsClient.jsm:455 InterpretGeneratorResume self-hosted:1158 AsyncFunctionNext self-hosted:693

The second one reads "Unknown Collection "main/cfr-fxa" in the headline, with the same text in the drop down menu as above.

Can someone please explain what these messages mean and if it is something to be concerned about?

I've spent quite some time, but couldn't find out.

Thanks

I simultaneously open two links of a bookmark folder by using the mouse scroller click. This is a most useful action, but once the pages are opened, they have to be re-selected to be pinned. Is it possible to open them in pinned mode?

When adding a bookmark on Firefox Desktop, putting a bookmark in a folder when adding it becomes cumbersome when one has a lot of bookmark folders and sub-folders. What I mean by that is that the user has to scroll a lot to find the folder they want to put their bookmarks in. It takes too much time. My suggestions for improvement:

1. Allow the user to resize the "Add bookmark window" so that they can quickly spot the folder they're looking for. The ideal would be to have the possible to maximize the "add folder" pop-up/window just like the one we have when we click on "Manage bookmarks" (Ctrl-Shift-O). This would be much faster.
2. Provide a search bar to quick search for the folder/sub-folder we want to put our bookmark in.

Hi, I have a Firefox account since long, I use it to publish my add-on. I haven't signed in recently and didn't take action when I've received an email that developers should move to 2FA. Now I'm trying to sign in to my account but it's always asking for the 6 digits security code, even though I have never set up 2FA on my account and thus don't know which authenticator app I need to use. Neither do I have recovery codes - naturally. Can anyone help me with my account? Best regards, Kaspar

Hi, I have an issue with making the separators in the bookmark toolbar drop-downs visible. I am running Firefox 95 with the Quantum - dark Blue theme installed. I am running Linix Mint Uma.

The dropdown have separator - space - but no line showing that there is a separator. I have tried many ways to make the separators visible and with light-grey colouring in the userChrome.css file but nothing changes.

Anybody have any idea what can be done or where I might change the Quantum-DarkBlue coding to incorporate the visible separators?
