Does Firefox support .mp4 video?

On page https://support.mozilla.org/en-US/kb/html5-audio-and-video-firefox?redirectslug=viewing-html5-audio-and-video&redirectlocale=en-US

I find "AAC and H.264/MPEG-4 AVC are patented audio/video compression formats. They can be viewed in Firefox using built-in OS libraries (so neither Mozilla nor you need to pay a fee) if embedded in the MP4 container format (.mp4, .m4a, .m4p, .m4b, .m4r, .m4v file types)."

But when I create an HTML page with the following HTML5 code:

<!DOCTYPE html>
<html>
<body>
</body>
This is a test of video.
<video src="C:/MyVideoFile.mp4" controls>
</video>
</html>

I get the error "No video with supported format and MIME type found". Does Firefox in fact support .mp4 video? If so, what changes do I need to make in the HTML?

Hello, we have a CVS repository which can be browsed using viewvc. In this repository there are some .docx files which are MS Word documents. Until about one week ago, clicking on such a link brought up a dialog asking what Firefox should do with this file. One of the options is to open it with Word (see image 'ChooseWord').

But now this is no longer possible. I believe it vanished in the course of the automatic Firefox updates. Now the dialog looks like in the attached image 'NoWord'.

How can I restore the old behaviour?

Thanks, gernot

So I've got Proton UI forced on me today in 92.0 update and accordingly had to spend my entire evening trying to repair all of the damage. So far I've managed to fix menu spacing and the way tabs look all while not breaking previous walls of text in userChrome.css meant to fix even older UI problems. Still one thing I failed to find any solutions to is the bookmark drop-down menus color issue. Those menus used to be gray, but now they are all bright white, which to me is super annoying. Any tips on how to fully recolor those?

I use the Bookmarks Bar extensively. But all the folders are the same color. I would find it much easier to find things quickly if I could change individual folder colors.

Any way to do this?

I'm already using Jscher's excellent UserChrome script to make the folders an attractive yellow, instead of gray. But can this be done for individual foders?

THIS keeps on happening at least 6 - 8 a year. ive cleared the cache off Firefox, rebooted it, got a now TESCO site and it is still the same. Yet Google fires up all right all the time. I have got 3 pc of a type and they all can get TESCO without any trouble. Ive been with you for 20yrs and am reluctant to change noW. Tesco just say your better of using Google than Firefox, which isn't much help. Yes they can get me on (sometimes) but they all ways say Google is the one really.

There must be something i can do?

I just recently upgraded to Firefox 87.0 (64-bit) for Windows 7. Before the upgrade if I wheel clicked on a link it would open up in a new tab. Now it does absolutely nothing. I've even tried holding the wheel click for 10 seconds, still nothing.

I have verified the following settings in about:config; browser.tabs.opentabfor.middleclick=true middlemouse.contentLoadURL=false middlemouse.paste=false middlemouse.scrollbarPosition=false

When I was doing a search for related questions to this problem I found a user 3 years ago had a similar problem, and that they had an addition setting: middlemouse.openNewWindow=true. This setting no longer seems to be there. I have no idea if this setting was recently removed, and is the source of my problem, or if it was removed a while ago and my problem is the result of some other change. I have restarted Firefox twice, and even rebooted my laptop, in an effort to fix this problem. Nothing has worked. Depending on what I am doing I rely on using the wheel click HEAVILY, as it is much simpler to close a tab then to hit the back button 4, 10, or 20 times to return to where I started, or if I'm trying to keep track of what links I've followed from doing a search without having to re-do the search and hope I get the exact same results (with Google I never do).

At this time I am already heavily inclined to just return to the previous version of Firefox, despite how much of a pain that will be, however this is a recently released update, so I feel I should give the devs a chance to fix any new bugs from the update. That, and I won't have the time around work for several days, probably over a week, which makes it more practical to give the devs a chance to release a patch that fixes the problem.

Every solution which I have found for Firefox 89 "Proton" so far which moves the Tabs Bar below the Navigation Bar (AKA "address bar"), with the Menu Bar above it, does NOT move the Tabs Bar below the Bookmarks Bar. The Bookmarks Bar appears to be overwritten and blank, and occupies space below the Menu Bar, Navigation Bar, and Tabs Bar. This empty space separates the three bars which are implemented and the content of the currently-selected tab below it.

Currently, my userChrome.css file is a copy posted by Corel-10 (?): __________________________________________________________________________________________________

Evidently, the text editor for this website does several things to the above original text that, frankly, seem unnecessary and undesirable. The .CSS file is just an unformatted text file, so what is the problem with simply copying its contents and pasting it in to the body of this post?

Which is also to say that I do NOT have a clue as to what any line in the file is meant to do, what effect it has, why it is even in the file at all, or why it is written in the way that it is. So DO NOT tell me that I "CAN" create a Cascading Style Sheet on my own when I cannot even modify one that has been provided. 

On the face of it, something is missing from the above CSS text. What change needs to be made to the above content so that the Bookmark Bar will appear between the Navigation Bar and the Tabs Bar??

Thank-you very much for your time and attention to this request for assistance.

Good Morning

Today I had to repair Firefox and after restarting, I felt a strange scrolling sensation, it was not the normal Firefox scrolling, I even thought I had openend the wrong browser...so I went check about:config , and found some values where changed as new default values:

general.smoothScroll.mouseWheel.durationMaxMS 200 general.smoothScroll.mouseWheel.durationMinMS 50

I tought it was me the problem so I installed an older version of Firefox (80.0) in order to compare, and found a normal scrolling and those values:

general.smoothScroll.mouseWheel.durationMaxMS 400 general.smoothScroll.mouseWheel.durationMinMS 200

I think this is a mistake from devs, if i wanted to have horrible scrolling, I could just use Edge instead of Firefox, could you please bring the original scrolling back to Firefox?

Thanks

Hi Mozilla Community,

Currently on version 97.0.1 of Mozilla and have not been able to download any files from Google Drive.

When I click on a files to download it just keeps loading scripts at the bottom like - docs.0k.cc.googledocs.... and nothing happens.

I have read countless of links to solve the issue and still it won't download any files - only uploads is fine.

So I have: - clear cache/cookies - disable addons like Adblock etc - privacy & security set on Standard in settings - added cookies exceptions- googlecontent, googledrive etc - turned off Enhanced Tracking Protection

What else is missing as to why it has stopped allowing me to download files? Its quite frustrating when it use to work when I enable the third cookie party and now the setup doesn't seem to accept it.

Mozilla is my default browser and prefer to use it rather always switch to Chrome for downloads.

I've contacted Google about Google Drive and they said the problem is not on their side.

So any help would be appreciated!!
