Firefox Community Forum

After an update to Win11 24h2 and every time I open Firefox a message (attachment) appears and I can't do anything. I've already uninstalled the app and reinstalled it and it still doesn't work.

I have two instances of two different profiles (lets call them profile A and profile B) of Firefox running simultaneously. When I click on a link in another application (for example a link in Thunderbird) the Firefox instance I started last will open up the link. This can be profile A or profile B, whichever I started later. However, I would like links to be open in the instance of profile A at all times. How can I do this without making sure profile A is started after profile B? Previously I could achieve this using the -no-remote command line option. This option has been removed from the latest Firefox version.

Another question about FireFox. I believe I have everything set correctly, please see attachment, but FireFox is not asking me to save my sign in credentials for my Apple account. It was working two days ago when I had to count on it remembering those credentials from over 2 years ago in order to change my password. After changing it I have signed in a few times to get it to remember my new password but it isn't asking me. Any idea why and how I can correct it?

As a hardcore Firefox fan, I've recently noticed an issue with video playback on Facebook. When I play a video on Facebook, it freezes after a few seconds, but the audio continues playing. The same issue occurs on YouTube as well. I already have H264ify installed and have tried all the solutions available on the internet. What should I do?

Here are my specifications: Firefox 132.0.2, Windows 10 (64-bit), 8 GB RAM.

Hi. I'm trying to troubleshoot failure to resume a download in Firefox and I want to see the HTTP headers just like in Network Tab of Dev Tools, but I can't find how to open Network Tab from the "Downloads" list. Is it even possible?

Normally, if I were to close a tab while using a regular Firefox window, I could use the Ctrl+Shift+T hotkey to bring that tab back again. However, if I do so right now (for example, Wikipedia's Mozilla article), I will not bring that page back but instead an older, longer-closed tab from some days ago. I can keep trying to close and reopen tabs, or just keep reopening tabs, and I will continue to dig up older and older tabs from longer and longer ago.

Is this a known issue, what might have changed that behavior, and how do I restore the expected functionality of tabs correctly being reopened in the reverse order that they were closed?

Hi ! I am using the latest firefox on win11 (latest updates). Since approx 2-3 days whenever I try to comment on youtube or edit an existing comment I cannot see what I am typing. I can still type and commit, the comment will appear and I it will contain what I typed. But when doing it initially it is invisble to me. If I reply to a comment I can see what I type.

Below 1st image shows a comment box I am actively typing in. Everything is invisible. 2nd image shows when I open a reply, you can clearly see the prompt and when I start typing it shows my input

Windows crashed my computer. now that it has been corrected i need to restore my old FireFox page and bookmarks. How can I do this? i prefer to speak with a rep. Ive tried following on the web but have no success.

When Firefox loads a web site such as TicTok.com, the site instantly plays the very first video that loads. Now this sure sounds like there would be a very simple solution for this problem and the solution should be built right into Firefox's settings... right? Let's see here...

Settings\Privacy & Security\Permissions\Autoplay {pop-up window} Default for all sites: [Allow Audio and Video]

                                   Block Audio
                                   Block Audio and Video

Website Listbox: Status: about:welcome^privateBrowsingId=1 [Allow Audio and Video] about:welcome [Allow Audio and Video]

   *the two dropdownboxes in this list have the same options as the 'all sites' dropdownbox.

So with these settings I certainly can block every website from autoplaying any audio or I can block every website from autoplaying any audio AND video. However these settings do not provide a "Block Video" only option. Why would anyone want that? Well because of the way sites like TicTok actually behave when Block Audio and Video is set. When Block Audio and Video is set, the user will have to press play on the video AND then press unmute. The user should be able to prevent the video playback when the website loads, and when the user presses play the audio should just start working without need for pressing unmute. This however, is only annoyance issue.

There is a real functionality issue as well. When looking at the Website Listbox, this component is essentially useless. The developers didn't even need to include the two "about:welcome" entries. They won't ever do anything unless Mozilla decides to add Audio/video to their welcome page (probably not happening). So the user can safely delete those two entries, but here is where it gets interesting. Once deleted, the user can not put them back. In fact, the user cannot enter ANYTHING into this listbox (why?). The only thing we can do is Remove All Websites.

What does this mean for the user? It means that I am relegated to either simply dealing with obnoxious websites and their autoplayed videos. Or I can set it so every website is blocked from autoplaying Audio and Video, but if I do that then I will have to unmute videos before clicking play. The presence of the Website Listbox sure does suggest that the user should be able to add websites, thereby creating a customized list of sites which should or shouldn't have autoplay permissions. To be quite honest, this part of Firefox seems incomplete and I hope it will see some attention soon.

So for example i watch video on youtube (doesn't matter, it happens on every site), and i want to skip 5 seconds, i press the arrow key and the video rewinds, BUT the sound is glitching a little bit, until these 5 seconds are rewinded, and its very annoying. Same sound glitch happens on BSOD, audio is just repeat last millisecond of itself. so how do i fix it? i dont have thins thing at other browsers, and also this glitch doesn't appear in every session, sometimes everything is ok, but not always

인터넷 웹 사이트를 보다 보면 어느 순간부터 동영상이 재생되지 않음. 주로 mp4 인것 같고, youtube 는 여전히 재생 가능함. 화면이 초록색, 혹은 검은색 등으로 반응을 하지 않고, 재생되지 않음.

개인적인 경험으로 유추해 보길 탭을 많이 열면 그런것 같음. 탭을 많이 열면 50~100 혹은 그이상도 열긴 하는데 한번 영상 재생이 안되기 시작하면 껐다 켜기전까진 계속 재생이 안됨.

혹시 설정에서 뭔가 수정해 볼 수 있는 방법이 있을지?

Trying to figure out why I can no longer save bookmark/favorite. Star icon is blue or turns blue when I click on it and then it does not save page? Windows 11 Firefox default browser.
