I have fedora 36 Linux on my laptop and I have installed Firefox from the software store. The version in Help>About>About Firefox shows 99.0.1 (64-bit).

I am able to play videos on Youtube but no video or GIF is playing on Twitter/Reddit/Facebook.

I have installed media codecs as per this fedora help

My autoplay setting look like as per the attached image. I do not have any extensions except Bitwarden on Firefox.

I also tried playing videos on Firefox 100 by downloading it directly from firefox website but faced the same issue.

I had been using Firefox browser for awhile, but because of playback performance issue, I have to using another browser just for video playing, especially for 4K video.

Compared to Edge, Firefox seems taking more resources to playback the YouTube video and more heat. When look at the Task Manager, the Video Processing is 0%, and GPU is running significantly more resources on '3D'.

Any way to cast to chromecast with firefox?

It's annoying that I have to use Chrome or Edge to cast youtube to my TV.

Or use my phone. But it's charging atm. So very annoying my favorite browser can't do this simple thing. But all the other browsers can.

Hi I have been a user of Firefox for many a year, and this is the first tme I've come across an intrusive problem. Since updating to the latest version, I find I can no longer change the icon on a URL shortcut. I had quite a few of them, which helped distinguish (obviously) what I might want to select. That was then. Now, I have a load of indistinguishable Fireox logos which make finding the shortcut I want imossible. On going to change the icons, I find the Website Document tab in properties is no longer there .. while I have Firfox installed. Remove Firefox and the capability magically returns. I have re-installed Firefox in case of corruption, with no change. Before I remove Firefox permanently (which I'd be loathe to do), does anyone know the cause ... or solution or workaround?

Until recently, I resisted allowing updates for Firefox because of the announcements of changes to prevent access to some technical kinds of website which I use. These include the public websites of the Paris Observatory which include useul informational ftp pages with important text, data and software files.

  I did recently allow a Firefox update, and now I find that I am cut off from access to these ftp pages. 
  How can I re-enable access to ftp? If it can't be done in the new version of Firefox, how can I return to an older Firefox version that does allow such access?

I am still stumped as to why Firefox crashes, IF and that's a big IF, my session is restored, why my tabs are blank but the website names are still on the tabs. Click to reload sometimes works, while other times it doesn't. Google, Facebook, Twitter, WordPress websites I am logged into and others will not load anymore for at least an hour. The only way to access them is to open a private window. What is happening to this browser that causes these sites to not load anymore? Any clearing the browser history/cache doesn't bring these sites back. They will only come back an hour after the crash. I've also cleared my ISP cache too (ipconfig/flushdns).

When I go to download a ZIP file, it will always attempt to download the file directly rather than letting me open it with WinRAR. When I go into the browser settings I see that some other file types have options to choose how they're handled, but there's no entry for ZIP files. I've tried refreshing my Firefox install and yet the issue still persists.

I used to have this option before I reinstalled Windows a while back (where I kept my files but not programs). I don't know for sure that that's what caused this to start, but the timing would line up.

My Honey shopping app is no longer working with the newest FoxFire update. I've uninstalled/reinstalled Honey THREE times and still not working. Have gone into Firefox App Manager and Honey shows green, meaning it has permission to run. HELP!

When I download a file before I even have a chance to save or open the file Firefox downloads the file and puts it on my desktop. I have to look at lots of .pdf files and this a bit annoying as I have to keep deleting all the files I dont want. The dialog box opens and I always choose open rather than save but Firefox has already saved a copy to my desktop. How can I stop this autosave please ? Cheers.

I cannot see saved credit cards in Privacy & Security Firefox 99.01.

I moved from a mac to Windows, and sync'd everything. I have no option to see saved credit cards in Firefox Privacy & Security.

Please help?

When I use Firefox on my Mac, no matter what I have tried it keeps defaulting to the dreaded Bing Search Engine. I understand it has to do with Microsoft, but I don't use any of their products because I don't like them. In settings/search I can restore the default search engines & delete Bing, but it always reverts back to insisting on using Bing again. I have followed several threads about this issue without permanent resolution. Help??

Hi there. I'm in the process of switching from Chrome and I want to import my passwords.

I first tried the 'import from Chrome' option - it says it's successful, but nothing has actually been added. Same result after several attempts.

I then tried the csv route. I found out I had to change the config settings, so I did just that, but the 'import CSV' option still isn't showing even after a reset.

So now I'm at a dead end. Any bright ideas please? TIA!

FYI I'm using Firefox 99.0.1

Hi there , I am interested to know if Mozilla support group is aware of the problem Microsoft update KB4474419 causes? I am running widows 7 sp1. I installed the update as you mentioned in your Firefox 100 release notes. After reboot , I got a beep and a black screen - win 7 won't start. I had to find a way to delete the update so I could boot my system back. I asked few of my colleagues that use the same OS and they experienced the exact same problem. Surfing the web , makes it quite clear - this update is faulty and not compatible with win 7 as Microsoft claims. I would like to get a straight answer - can I update my FF99 to FF100 , without the notorious KB4474419 , or , as of FF100 , win7 sp1 is no longer applicable to Firefox ? Thanks. look4

Hi everyone,

Last Saturday, I was able to sign in to Firefox Add-Ons Firefox Add-Ons and submit a pre-release of an add-on I'm working on. But today, I'm being forced to enable 2FA to simply log in to the site. I don't want to enable 2FA, I just don't need it. Can someone explain me why is this happening ? Can I just log in and submit my add-on's update ?

I've tried to sign in two different MacBooks (M1 12.1 and Yosemite 10.10.5), using two different Firefox versions (99.0.1 and 78.15.0esr). Also, I haven't enabled 2FA in my personal account.

Thanks in advance.

Since the Firefox 99 update loading some pages (for example, the Gmail sign-in page) using Firefox on my Linux Mint machine, that I'm running a VNC remote desktop session on, results in a crash.

Crash report ID: bp-5dc1e89d-dc1f-40f2-9dbe-7f4380220419

I've tried running Firefox in safe-mode and the crash doesn't happen, but turning off hardware acceleration, swapping to default themes, removing all extensions, and completely removing Firefox and the .mozilla folder and then re-installing Firefox have not changed the crash behaviour in the absence of the safe-mode flag.

I would appreciate help in identifying what other paths of investigation I can take.

When I start to type a reply to a Facebook post, the page scrolls down so that the line I am typing disappears one line below the bottom of the screen. I have to scroll down to see what I'm typing. Also, it jumps down the same way whenever I hit the backspace key to edit what I'm typing.

I discovered a previous (archived) post on this forum that suggested using "about.config" and making sure that the value setting for browser.backspace_action is equal to 2. But that didn't change the annoying behavior. Is there any other value I should try? It's not clear what the number means.

Nor did setting browser.backspace to true (or to false) seem to help with the unwanted jumping upon use of the backspace key.

This only seems to happen with Facebook, but it's quite annoying.

I wanted to print out an order placed online but could only print part of it.

The order took up about 1.5 pages when displayed in Firefox, but I could only print the upper 2/3 of it. That’s all the Print Preview displayed. It was cut off at the bottom. There was no option to print the missing lower third or a second page.

I can scroll Firefox to display the lower part but Print Preview still shows only the upper part.

I can change FF’s scale to 80% in order to show the whole order on the screen, but Print Preview still only shows the upper part.

I can scale Print Preview to 70%, but then it’s difficult to read.

I don’t recall having this problem with earlier versions of Firefox.

How can I print my order on 2 pages so that I can read it?
