Problems with slowness and crashing. Checked manage data and found this message: Your stored cookies, site data, and cache are currently using 17,179,869,184 GB of disk space. Cleared yahoo.com and yahoosandbox. A few days ago it was google.com causing this same absurd data message. v 94.0 on Linux

Hi all. Did a search but found nothing that helped. Just updated my Fedora 36 workstation and tried to play videos in CNN and MSNBC web sites and get the error message: "Code: 4 | Message: Something went wrong during native playback." I am using the latest Firefox WEB browser. UTube videos are playing fine. Someone has stated on the Fedora forum that they have the same problem but has no problem in Chrome on the same machine. Any ideas? Thanks in advance. Bob BTW, this happened in two machines running Fedora 36 and Firefox 101.0.

I am using Linux Mint 6.0.3.1 , and my Mozilla Firefox version is 77.0.1 . My Firefox will not update, neither automatically nor when prompted. When I go to all the pages for downloading and installing the newest Firefox, I am always able to download a package, which appears as a folder labeled " firefox-89.0.2.tar.bz2 " but then I cannot install it, it just appears as a folder full of files that will not run. I have tried following the command lines in the terminal that these pages claim will make the new version run, but I always just get a response like "no such command" or "no file exists." Shouldn't there be some relatively simple and reliable path to just get firefox 89 onto my computer?

This question was asked 6 months ago and I have the same problem.

Running Ubuntu Mate 21.04 (metacity), FF 91.0.2 (64-bit). I have it set up with two different profiles, with separate menu entries for each using "firefox -P [PROFILE NAME] -no-remote %u". One of them is set to always use private browsing mode and I use that profile as my default app in mate.

If if set chrome as my default browser, I can open links from other apps without a problem regardless of chrome being already running or not.

When I set FF as default, whenever it is already open and I try to open a link, I get a "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile." error.

I've seen some comments about similar issues with wayland and tried setting MOZ_DBUS_REMOTE and even MOZ_ENABLE_WAYLAND to 1.

Can you help me?

"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 am keeping trying to set up a two-step verify on my firefox account, but stuck on the last step of input the recovery code, even if I input the right recovery code, it still tells me I entered wrong code.

Hi everyone,

I am running Firefox 91.5 on Red Hat Enterprise Linux 8.5 and just noticed that all my addons have been disabled and can't re-enable them.

Some of them are quite common modules such as Disconnect or Privacy Badger, so wondering what this may be.

There is a similar post on this forum dating back to 2019 and it mentioned a fix on Firefox was to be developped.

Anyone experiencing the same issue at the moment.?

Please see attached screenshot.

Kind regards,

Alex

Hello, recently Ctrl+Shift+M has been grabbed by Firefox but I had already mapped this shortcut to a command in my desktop, how do I disable this shortcut in Firefox? Thanks!

Firefox 89 on my Raspberry Pi 4 is displaying what I'm guessing is a codec issue. Videos can be watched but the picture is corrupted by brightly coloured patches around areas of detail.

Prior to the version 89 upgrade, version 88 was working perfectly.

I have Firefox 89 on a Raspberry Pi and a PC. On the PC it still works perfectly, on the Pi video is displayed badly.

On the Pi Firefox 89 is running under Ubuntu 21.04. On the PC Firefox 89 is running under Ubuntu 18.04

Am I alone in this or have others seen the same issue ?

Assuming I am not alone, does anybody have any idea what has gone wrong ?

I've just started noticing in Firefox 99 on Arch Linux that Firefox is using the wrong font when the font-family is given as "ui-monospace/other fonts..., monospace". This looks similar to the issue mentioned here: https://support.mozilla.org/en-US/questions/1351497

The inspector for these websites underlines "monospace" as the active font, but then uses a non-monospace font (in my case, Bitstream Vera Sans) to display the content. This does not happen when the font-family is "monospace,monospace" or "monospace". I can't quite figure out exactly what causes the font to be chosen incorrectly: sometimes it does show up if I have the preceding fonts installed, e.g. Consolas or Liberation Mono, but other instances do not look as intended.

Currently, I have fontconfig set up such that: $ fc-match :family=ui-monospace VeraMono.ttf: "Bitstream Vera Sans Mono" "Roman" $ fc-match :family=monospace VeraMono.ttf: "Bitstream Vera Sans Mono" "Roman"

Firefox's fonts in about:preferences are configured as all defaults: Serif: Bitstream Vera Serif Sans: Bitstream Vera Sans Monospace: Bitstream Vera Sans Mono

My old Linux computer died and I have removed the still good SSD from it. I have installed the latest Firefox on my new computer and would like to restore the bookmarks and other saved data to the new computer.

I am running Ubuntu 20.04, the old computer was on Ubuntu 18.04.

Can these things be restored, and if so what do I need to do?

Heyho Supporter, Helper, Life rescuer The addon YouTube Video and Audio Downloader (Dev Edt.) 1.1.5. give an error if i try the button "Download Panel" -> "info.player_response is undefined"

No one in the web have this problem i guess. I can't find actually threads to it. It seems, i am the virus.... Linux  : ubuntu 20.04.2 LTS mate 1.24.0 Firefox  : Version 89.0.1 (64-Bit) addon  : YouTube Video and Audio Downloader (Dev Edt.) 1.1.5. maybe important : my location is Germany

Many web-sites want to have geo tracking. Firefox ask me often to block or not block the location info. perhaps i give firefox the order to block my location info every time for the youtube page. And the downloader need this info?

So how can i chek this geo-blocking status for the youtube page? or how can i allow this geotracking generaly for all till i testing the downloader with this firefox permission.

Or what else can be my problem with the downloader? the downloader works fine for a long time and give the error (above), since 10 days. I try already a new installation of the addon and different youtube videos. Also i try an other mp3 downloader/converter suggest full but i don't want to use this one.

I hope you can understand my English and my problem with patients.

Why are vertical spaces different in my bookmarks from my personal bar, the lateral panel and the library window ? How to fix it, as I want everything same ? I'm unable to take a capture of my personal bar where vertical spaces are bigger than elsewhere.

I store passwords on firefox account and use sync to share passwords across devices. I did not delete any passwords on any device. recently, I saw that only google account passwords are missing and rest passwords are intact in saved passwords. my google passwords have been stored since a long time. all my old and recent stored passwords are shown in firefox but only my google account passwords are gone on all the devices. I tried login-backup.json but there is no change in passwords shown. need help.

Since Firefox has been updated, the interface is completely unusable. The frame does not render properly. I can use Firefox only in safe-mode with the terminal. The new WebRender seems to be the problem.

What did I do then ?

• I entered apt purge firefox for full removal and reinstall -> Didn't work.
• I disabled in about:preferences hardware acceleration -> Didn't work
• Downgrade to Firefox 88 -> Worked.

I love the new interface and the new render process. But if I can't use it on my home workstation, things are going to be hard for me.

I added a screenshot to show the problem.

Thanks by advance !

Hello, as of today my Firefox Windows is half transparent. Including all Task Bars and drop down menus. Rendering it quite unuseable. This behavior is unique to Firefox, other Applications are not affected. When I boot Firefox in the Debug-Mode the transparency is gone. Can someone tell me what the Issue may be and how I can disble this setting?

Operating System: UbuntuStudio 20.04.2 LTS Firefox Version: 89.0 (64-Bit) Mozilla Firefox for Ubuntu canonical - 1.0 Used Theme: the standard dark theme from Firefox in Version 1.2

OS: Ubuntu 21.04 x86_64 CPU: AMD Ryzen 7 3700X (16) @ 3.600GHz GPU: NVIDIA GeForce RTX 2060 SUPER

When I have two windows running and one of them is playing either audio or video on its active tab, the other window runs at a very low FPS. This is noticeable when scrolling, as CPU usage appears to increase dramatically while monitored.

The problem does not appear when running firefox in safe mode, but I cannot determine what might be causing the problem when firefox runs normally: the problem persists when I disable all extensions, as well as when I use the browser's default appearance as opposed to the theme of my choice. As far as I can tell, I have not modified any about:config settings either, although some cursory searching online suggests webrender may be a cause.

Hello.

I got a little problem with firefox starting with somewhat broken window layout on my Ubuntu 20.04 desktop with KDE desktop environment. Tried to google for it unsuccessfully, so here I am. Whenever I start firefox after cold boot or a full reboot, it runs like on a screenshot. The workaround for fixing that is to resize window and then make it maximized again. I am not quite sure, is it a problem of browser, video driver, or desktop environment, but it occurs for me only on firefox.

• Appeared several versions ago, present on current version I use: 89.0.2 (64-bit)
• Does not appear when i load windows 10 on this PC.
• Video card: Nvidia 1660S driver ver.460

Does anyone heard of that problem? Would be glad to know any details to address this problem.
