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

Followed instructions on https://support.mozilla.org/en-US/questions/new/desktop/form and https://support.mozilla.org/en-US/kb/how-disable-enterprise-roots-preference "security.certerrors.mitm.auto_enable_enterprise_roots" is set to disabled but "security.enterprise_roots.enabled" is set to true but is greyed out and I do not have a toggle option to disable it - why and what is the solution ? No Anitvirus software except windows 11 defender is installed.

No "ImportEnterpriseRoots" entry available in registry and no HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\.... entry

Please help!

Foxnews.com causes Firefox 102.0.1 to freeze when scrolling pages with lots of images. Closing and restarting FF does not help. The freeze reoccurs. What does help for awhile is to delete the file places.sqlite. After that FF runs for a few hours until the problem happens again. Is there a setting or other fix for this issue?

AdBlockPlus and uBlock Origin are both installed, but are disabled on www.foxnews.com.

Hi all.

I use Firefox 120.0.1 with the setting "Delete cookies and site data when Firefox is closed" to clear said data when closing Firefox. I have also set an exception for a few websites, so they should save cookies and data. However, this does not work as intended. After closing and reopening Firefox, both cookies and data are gone from these websites. I have looked for a solution in older forum entries, and it was recommended to adjust the history settings. It seems that checking the box at "Delete cookies and site data when Firefox is closed" automatically sets the history settings to what can be seen in the attached screenshot. Altering these automatic settings unchecks the box above. Is this issue related to the website or is there a way to solve it?

On FF 120.0.1 and Tab Reloader 0.6.1

I have FF set up with 7 tabs as home page, 6 of the tabs have tab reloader set to reload ever 1 hour. This has worked fine for years, the tab reload for the 6 tabs were saved after restarting FF. I didn't have to go back and tell tab reloader to reload after restarting FF. Maybe once and a while one tab didn't get the reload saved on a restart, usually always the same one.

Now when I restart FF none of the tabs have saved the setting to reload every 1 hour.

This has been going on for the last 2 releases of FF updates and there hasn't been any updates for tab reloader. Does anyone know why this is happening, I haven't changed anything in settings. I did uncheck hardware acceleration to see if that would fix another issue, but tabs weren't reloading after restart prior to that change on hardware accelation.

I've got a question/suggestion about Picture in Picture feature. Why "Close" button works the same as "Back to Tab"?

Scenario: Close the Picture in Picture video by clicking on the [X] button or Cmd+W shortcut.

Actual result: Picture in Picture closes and Firefox window opens, on the tab containing the video. This is very strange behaviour. If I close the video, I don't want to watch it now. Essentially "Close" button works exactly like "Back to Tab" button - so what's the point? If I wanted to switch to the tab - I would click on "Back to tab".

Expected result: I expect Picture in Picture video to close and nothing else to happen. Don't open the window/tab containing the video.

Thanks

I have Firefox set to ask me where to download files that I want to download. It works for normal download links, but when I'm using my credit card company site's PDF viewer to look at a statement and I click on the download icon or link in the upper-left, it simply downloads the PDF (to my chosen "Save files to" folder in Settings). Is there a current way to change this behavior? Is this something that the website's code determines, overriding my Firefox setting?

I had a laptop Windows 7 laptop that fried itself, a puff of grey smoke came out of the air vent on the side of the laptop and now I have a Windows 10 Pro laptop. I saved the file "Old Firefox Data". Were do I insert these two files (folders) in Firefox to restore it back to it's condition before the new laptop?

Firefox has started hiding all tabs in a window except the active tab. This has happened in two different windows. I have no idea how to hide tabs and don't want to. How can I unhide the tabs. When I try to do it one by one, the first tab rehides when the 2nd one appears. Can I unhide multiple tabs at once? Do I have to unhide them one by one, and if so how? How do I stop Firefox from hiding tabs?

I can't access this web page: www.fivelakes.settlement.com. This comes up:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at www.fivelakes.settlementaccount.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

learning windows 10 - closed a window retrieved from the taskbar - can i get it back with its 49 tabs? i can get an active window showing the recent files i was working with, and i can open ONE of the tabs ("one document") - went too fast i guess. thanks for any response. hope i did the "share data" for you properly.

I had to totally rebuild my system from the bottom up. I had a copy of my old profile stored in the cloud, so I figured I was OK. When, I copied the files from the saved profile to my new profile, everything came over except my bookmarks. I copied the places.squlite and favicons.squlite files (which I understood to contain my bookmarks) separately and pasted them separately into the new profile, but to no avail. I used to keep a separate backup of my bookmarks, but when I learned that the bookmarks were kept in the profile, I stopped. How far up the creek have I gotten myself stuck, and is there a way to restore my bookmarks?

'I want to reduce the height of the two ribbons, (the tabs ribbon and the search navigation ribbon) at the top of my browser so that they do not take up as much height of the screen display. How can I do that?
