Hello, can you add better support playback on .mp4 videos? Seems with Firefox it's a hit-and-miss with some .mp4 videos that will play and some that will just show "No video with supported format and MIME type found".

All other browsers will play .mp4 videos without an issue but Firefox won't.

If you can provide better .mp4 playback support that would be greatly appreciated. Thanks

Here's one of those videos for an example: https://drive.google.com/drive/folders/1Fv6SdftiCXeYPQOdF17H2JNpwjMu9P7q

Pretty much a URL string like example.com/videosample.mp4

Videos can't be played at higher playback speed Bug

On firefox, I cant play videos at higher playback speed or it'll only play audio or video will endlessly buffer. Using user-agent spoofer and changing to chrome makes it a little less worse but still the problem sustains. On Brave, the video doesnt have any effect of higher playback speed rather it'll make the video buffer and have very strong red contrast.

I have been having with YouTube for a couple of days. It asks to turn off ad blockers. I have done so and it still requests to turn ad blockers and still won't allow viewing. YouTube works on other browsers.

I am sure YouTube is playing games but can you help?

I see a similar question on the forums from March 2021, but I'm having this problem now: when I go into icloud.com, it keeps asking for authentication - i.e. it presents a 6-digit code which goes to my phone/ipad, and I have to put it into the browser. After that, I'm prompted "Do you want to Trust this browser" to which I ALWAYS say "Yes", but it doesn't seem to work; the next day, if I try icloud again, it does it all over, like the "Trust" option is ignored. In settings, "Delete cookies and site data when Firefox is closed" is unchecked, Clicking "Manage Data" shows that cookies for icloud.com are saved. I've just added icloud.com into Exceptions to Allow to use cookies/site data, though I wouldn't think I'd NEED that if I'm never deleting them. I tried this with Chrome, and the Trust DID work; I can sign in with that browser and not have to put in the code.

What's up with that?

Good morning I would like to ask how to configure (set) the Firefox browser on a computer with Windows 10 so that when clearing cookies and history, cookies and login data that have been added to exceptions are not cleared (deleted) when closing the browser: How this setting should be done (what options are selected) Privacy and security - clearing history when closing the browser Privacy and security - deletion of cookies and site data on closing (exceptions - allow) Please reply Regards Zbigniew M zbigniew14@gmail.com

I have dealt with this message when searching the web... after a google product search etc., the results populate- then I click on all the top results and I get nothing but this message and the sites will not open:

Secure Connection Failed An error occurred during a connection to www.googleadservices.com. PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

I noticed it's with most "Sponsored" results. Incredibly frustrating.

Please help!

Is there some way to enable and disable specific config settings , on a per-site basis?

For example, let's say I want to disable right-click hijacking (dom.event.contextmenu.enabled) on turtlesaregreat.com, but use the default settings everywhere else.

The Page Info > Permissions panel has some, but not all the ones I want. Is this somehow built into Firefox, or maybe there's an extension?

Thanks.

You somehow have old, outdated information in your system. Your new browser requires me to log into a facebook account I closed 10 years ago. My password for my current account named, "VangiePangie", now opens a closed account named "Evangeline Custis". I no longer have access to my VangiePangie account with any password. So, I no longer want this new upgraded Firefox account. I want to have my old Firefox account as a default on my desktop. Right now it's an icon at the bottom of the screen, and I can only use it to open one thing at a time. Please give me back my old Firefox browser. I'll struggle with Facebook to get my password to work on my VangiePangie account. I have access to the VangiePangie account right now, because it was never logged out in my old Firefox browser and is in my Bookmarks. But if I am forced to log out, or if Facebook does a security check, I won't have access ever again. Please help me with this. Below is my VangiePangie Profile pic.

Hello! I want to remove help-button, password-button, addons-button from the (hamburger) menu of Firefox. To do this, I created a chrome folder in the browser profile, inside which there is a file userChrome.css. Contents of the css file

@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);

1. appMenu-passwords-button,
2. appMenu-extensions-themes-button,
3. appMenu-help-button2

{ display:none !important; } This css file was removed from the menu: passwords, extensions. How can i remove help button? And second question - how to remove the copy and show password buttons from the passwords tab? Thnx for answers!
