Today I updated my Firefox Developer Edition to version 89.0b2 and now I just can not look at this browser anymore, "Inspired new tab design" is taking too much space and now became largest and at the same time least information-dense panel in my entire desktop! I searched around the web for a bit in hopes that I will find a theme or an add-on that will revert this particular change but no luck. I really want to revert to old UI look (at least tabs bar), there should be default theme or option to get back to old style. After some investigation I found userChrome.css but don't really want to install it (maybe this is actually the way of doing this kind of styling). Please help me revert UI design to old one.

Hi, I faced the problem with Youtube recommendations on a video page. When I watch a video I can't see recommendations, comments and video title (see the image). In console i get an error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://googleads.g.doubleclick.net/pagead/id. (Reason: CORS request did not succeed).

I am on arch linux system.

I've tried to: 1. Update all ca-certificate* packages 2. Disable and delete ad-block 3. Use another browser (there is no problem, only in firefox)

This problem is only actual on Youtube for me.

Hi all, I have an Apache site on Kubuntu 20.04 with a certificate signed by my private CA. I've added the root CA ceritificate in Firefox and in Chromium.

Firefox throws a SEC_ERROR_BAD_SIGNATURE error

Chromium accept the certificate as valid

What can I do?

Notes: the site url is "https://hdev.h.net" (with an internal IP address inside my lab)

Attached there are:

- the authority settings page
- the certification authority certificate as seen by Firefox

After installing the DRM content through the browser I still cannot play any videos on Netflix or Udemy.

I have run this website (https://www.jeffersonscher.com/sumo/html5-video.html) from previous answers to check and the results are attached to the question.

I have also checked media.eme.enabled and it is set to true.

I am very much puzzled by this.

Starting as of today (Oct 13), the FACEBOOK screen suddenly moves when I am typing a comment. Whenever I hit SHIFT+alpha_letter at the beginning of a line OR simply hit the backspace key, the screen suddenly shifts about a page up, closer to top. This shifts the entry area where I'm typing down and off the screen. Just hitting the backspace to correct a typo causes the screen to scroll on its own. I have to scroll back down to the entry box and if I make another typo, it happens again. It is maddening!

I've restarted in troubleshoot mode and the same thing happens, so it is not an add-on. This is happening on both my Firefox Linux systems AND on a Windows 10 machine, so I don't think it is specifically OS related either. The screen however does stay put, like it is supposed to, using Chrome or Opera.

Is this a Firefox problem or is FACEBOOK messing with Firefox?

Is there a way that I can change this setting in config rather than downloading an add-on? This changed with the most recent Firefox update for me (I'm currently on 85.0.1. for Ubuntu). Currently, the default save behavior is for bookmarks to save to the most recent folder you've picked. My preferred behavior would be for all bookmarks to save to "Other bookmarks" until I can file them away later.

Since installing the latest Firefox update I have been unable to view Amazon Prime videos. I keep getting this error message: Digital Rights Error Your web browser is missing a digital rights component.

In your web browser's address bar, type about:addons, press Enter, and then on the left, click Plugins. For the Widevine Content Decryption Module, select Always Activate, and then refresh the video's page and try watching the video.

If the video doesn't play, go back to Plugins, click the gear icon at the top of the page, and then click Check for Updates. When the plugins have updated, refresh the video's page, and then try watching the video.

I had no problems with the previous version of Firefox. I am running in Linux Mint 20.1, Firefox 89.02, 64 bit.

Hey there,

I have the following issue with Firefox, is this maybe something I should report to the Ubuntu support or directly to Bugzilla?

Steps to reproduce: ---

  1. Open Firefox
  2. Go to a page that contains an embedded video that is not playing automatically, e.g. https://www.rottentomatoes.com/m/sound_of_metal
  3. Do not play the video

Environment --- User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:83.0) Gecko/20100101 Firefox/83.0 Firefox version: 83.0 (64-bit) pulseaudio version: 13.99.2 OS: Ubuntu 20.10 64-bit Gnome version: 3.38.1 Windowing system: Wayland CPU: Intel® Core™ i7-8565U CPU @ 1.80GHz × 8 RAM: 15,5 GiB GPU: Mesa Intel® UHD Graphics 620 (WHL GT2)

Actual results --- pulseaudio process is spawned and rapidly becomes the most CPU consuming process on my machine (especially after a few seconds, when the Web Content ones start to cool down). Even though no sound is actually played! When switching to another tab with no embedded video, pulseaudio keeps overloading the CPU. This only stops after closing Firefox.

Expected results --- I'm not sure this is what should be expected, but I'll give it a shot:

  • pulseaudio process should only be spawned when actually playing a media that requires audio
  • pulseaudio should not be the #1 CPU consuming process
  • pulseaudio process should at the very least not massively use CPU when no sound is playing

Hi. Previously I installed Firefox on Ubuntu with command `sudo apt install firefox`. I'm using Firefox 88.0 for Ubuntu. I want to update it to the latest version. When I try following commands: `sudo apt update` `sudo apt install firefox`

It says "firefox is already the newest version (88.0+build2-0ubuntu0.20.04.1)." But I know version 89 and 90 are released.

I attached "About Firefox" window. There is no update button.

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
