Hi there,

I am running Firefox (104) on Linux (Arch Linux) in the Sway WM on a laptop with a modern (2021) AMD CPU and integrated GPU. I have installed (and verified that it is working properly) all the necessary drivers (mesa, vaapi, etc.) and updates, yet under about:support, HARDWARE_VIDEO_DECODING is blocklisted by env: Blocklisted by gfxInfo. How can I find out what exactly is blocking it? Might there be an environment variable missing or something like that?

I know that I can force-enable it through a settings flag, but this is not what I am looking for, I want to know how I can find out why it is blocklisted. (Setting hardware acceleration manually works without issues)

I have looked at https://fossies.org/linux/firefox/widget/gtk/GfxInfo.cpp and starting from line 860, my setup should only be blocklisted if I do not use Mesa (but I do).

Additional information: XDG_CURRENT_DESKTOP is set to "sway".

I would really appreciate if someone could point me in the right direction on how to find out why my setup is "blocklisted by env".

OpenH264 fails to install with HTTPS-Only mode enabled

"OpenH264 Video Codec provided by Cisco Systems, Inc." plugin will sit in the "will be installed shortly" status forever if you have HTTPS-Only mode enabled. I have been pulling my hair out for the last few days trying to figure out why I couldn't play YouTube or many other sites videos.

Turns out the site that the library is downloaded from has a bad certificate installed: https://ciscobinary.openh264.org/libopenh264-2.3.0-linux64.6.so.bz2

``` Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for ciscobinary.openh264.org. The certificate is only valid for the following names: a248.e.akamai.net, *.akamaihd-staging.net, *.akamaihd.net, *.akamaized-staging.net, *.akamaized.net

Error code: SSL_ERROR_BAD_CERT_DOMAIN ```

OS: Fedora 36 Firefox Version: 104.0 (64-bit)

I started having this issue after a crash with an update to version 103 after restart. And since then when I open firefox in full screen (mac) and open a youtube video and click the picture in picture mode, firefox will just open a open/popup a new picture in picture in full screen mode instead of a smaller picture in picture window. I'm not sure if this is a macos bug or firefox.

So I am a web developer, is there a way to change the version of Firefox developer to the latest Firefox version? Because it is currently in beta version.

I am using Firefox developer for web development, and also for testing, and also for day to day web browsing. I just realized that the Firefox developer is a beta version, but our users use the latest version of Firefox. I believe this can be a problem when the development environment is not the same as the user's version.

If I install Firefox's official browser, it will be a waste of storage.

I forgot my password to Firefox Sync account. But at the moment I can still access the account from one of my devices which i have previously logged in, and needs a way to backup all the sync data so I can restore them back to Firefox Sync after resetting the password. As I read, resetting the password clears all sync data as Firefox cannot decrypt the data without the old password. Is there a way to backup my current Sync data, and restore them after the reset? If so, can you please guide me on how to do it?

Tried restoring through menu several different bookmark dates, different size/link amounts, loops and never completes.

External backup in future, best way???

Other issue is copying link from a Google tab, to a Facebook tab, have about a 10-20-second delay (a block) before I can access the Facebook tab to paste the link - This worked fine until about a month ago. Opera work fine.

Should I forced FF to complete SANDBOX mode to restore functionality??? Switch to DEVELOPER version??? Try to GO-BACK MUCH OLDER VERSION???

Thanks,

Tim

Hi,

The saved-telemetry-pings folder in my Firefox profile doesn't get cleaned up of the old telemetry pings, and it just keeps growing over time.

I have pings in this folder that are from October 2021 and I doubt this is a normal behavior.

It's not the first time this thing happen, and October 2021 is probably the last time I cleaned this folder.


How do I make it so it doesn't keep telemetry pings, but I can still use telemetry. I use the beta Firefox, and I'd like to keep some telemetry as some of the devs at Mozilla foolishly rely on the telemetry to slash features, when telemetry is so broken it's better set to disabled than enabled.

The problem is as follows:

Every time I load some multilagual web page (Aliexpress, prestashop.com fox example) Mozilla loads the page in different language. After I change the language and load a new page from the site, the language is changed again to a random one. Every time I click a button or link, the language is changed.

Cleared cache, and cookies and everithing multiple times. After 3-4 days it does the same thing. Tried fresh install - after a while starts to do the same thing. Installed Firefox Developer Edition - after 6 months starts to do the same thing. Installed Waterfox on different PC - same as Firefox Developer - after 6 months starts to do the same thing.

Does anyone have the same problem? Why is it happening? Is it only me?
