When clicking on a link to an .mp4 file, Firefox navigates to a builtin video player, streaming the remote video file. When Firefox is unable to stream or display a file (as is the case with .mkv or .txt for example), it is downloaded instead.

I simply want .mp4 files to be downloaded when I navigate to them. I tried setting `media.mp4.enabled` to `false`, and that worked, but it also disabled most embedded media players.

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 Cor-el (?):

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

/* TABS: below nav-bar - fixed for 108+,113+ */

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.

I really often need to copy/paste from a terminal opened in my browser. Because the shortcut for copying in a terminal is always Ctrl+Shift+C, it's a mess to have instead Firefox opening Inspector from devtools.

How can I disable this shortcut ?

I've tried to update some about:config settings but it doesn't seem to be helpful and old working correctives add-ons are not supported anymore.

Hello everyone,

to archieve some good old games, I use an special version of Firefox. Firefox (MyPal): 29.2.0, with Adobe Flash preinstalled, Disk-Cache

For most games it will suffice: After loading all content online, it will be available offline too. But... some audio/video files will be saved in memory cache - %temp%\mozilla-temp-files\*[random-auffix] - instead of in disk cache. After closing session they get deleted and after restart they are saved again, with another suffix.

Sample file: http://arcaneonlinegame.epizy.com/Arcane/frames_files/midi/Ophelia's Journal.mp3 that is shipped with http://arcaneonlinegame.epizy.com/Arcane/Arcane.htm

How can I tell Firefox to permanent save streamed audio/video files, like Firefox does with everything else? In the end the music should play if I open the browser offline too.

Thank you in advance for your help. Drago

Hey guys,

is it possible to disable the "saved logins" dropdown, whenever a password/email field gets focus? (see image)

I've already disabled "Autofill logins and passwords", but that just disables not directly autofilling the field.

I want to disable this field, since I can still use saved logins via right click "use saved password", which i prefer.

Its no form field, i've already checked that + it occurs on all login pages.

The only options i've found where: "signon.showAutoCompleteOrigins" - hides from which website and "signon.showAutoCompleteFooter", which hides the lower part with "view saved logins"

Is there a way to disable this Dropdown completly, without loosing the auto save/ask to save new passwords?

Kind Regards

Firefox 104.0.1 (64-bit) - Fresh install (just imported logins)

Procedure is written on this article: [[Tip] Enable Firefox to Show Media Controls on Windows 10 Lock Screen – AskVG](https://www.askvg.com/tip-enable-firefox-to-show-media-controls-on-windows-10-lock-screen/#:~:text=If%20you%20are%20using%20Windows,enabled%20preference%2Fflag%20to%20False)

Windows has feature that displaying media control popup on its lock screen. Firefox has an option to turn this off via advanced setting, but turn "media.hardwaremediakeys.enabled" to "false" doesn't stop showing it up.

Also, on certain website (in my case tweetdeck), control screen of previously viewed and closed video is keep showing up and can't erase it unless restarting browser.

I asked this question on Microsoft forum but suggested it's Firefox issue. Does anyone have same problem? How can I fix this?

Hola , alguien sabe como puedo ver los videos de Disney plus en pantalla completa , sin las barras negras , al parecer los vídeos son 21:9 y mi monitor es 16:9 , alguna extensión que si funcione para cambiar la relación aspecto o hacer zoom ? gracias de antemano

Hello, does anyone know how I can see the Disney plus videos in full screen, without the black bars, apparently the videos are 21:9 and my monitor is 16:9

Unfortunately, I downloaded “SaveFrom.net Helper” without reviewing it.

Since downloading it I have been receiving a alerts from “McAfee WebAdvisor” about “dangerous pages blocked”.

I was able to remove the “SaveFrom.net Helper” add on in Firefox, but am unable to remove the “Savefrom.net Helper” bookmark tab which has high jacked my normal Firefox Bookmarks.

I can no longer easily see my Firefox Bookmarks and have to keep opening the Firefox Application Menu, then select Bookmarks, then select Manage Bookmarks in order to see my bookmarks.

Can you please advise how I can safely remove the “SaveFrom.net Helper” bookmark tab which has high jacked my Firefox Bookmarks.

I can change the color of links and background in Firefox options. But i want only to change the colour of visited links on all pages and NOT also the colors of background and text. These 2 options are connected which is not practically i mean.

Are there addons who could do this? thx

I can't get Firefox to use some custom cursors. Firefox is only recognizing the cursors that came installed with Ubuntu. Any of the cursors I installed will default to DMZ-White, but Firefox is using those cursors that came installed with Ubuntu. I tried defining the default cursor in /usr/share/icons/default/index.theme but did nothing as well. Also I tried with the cursor in /usr/share/icons and in /home/name/.icons and firefox cannot get in any of those.

I don't know if it's something wrong with my cursors or it's some inner thing with Firefox, any one has a guess? Incompatibility or something missing from the cursor?

This is more of a convenience issue but the new download panel pop-up from the download arrow is very distracting. I couldn't find an option to turn it off so I had to go into the config and turn the true flag false for this "improvement". Is there a better way of disabling this pop-up and if not will there be in future versions of firefox?

After an update today, private browsing windows now are a different color than the other windows. I don't want them to be a different color. How do I change them back to the same as the other windows?

Also, how do I remove the extra text label next to the private mode icon, and just generally put things back to the way they used to look?

Hello.

It seems I get a problem or two almost always with a new update lately. I have been using an userChrome.css to reduce the width of sidebar but the latest version 107.0 now ignores it and have a wide width even at the narrowest. Mine currently is set as, "#sidebar {min-width:30px !important; max-width:none !important;}" This no longer works. Your support much appreciated.

Regards,

Is there any way I can completely disable horizontal scrolling? I'm using a laptop with a trackpoint (lenovo x230, Windows 10) and it's not terribly accurate, which means scrolling whilst a youtube video is going often makes it track backwards or forwards, and another website I use uses a horizontal click to send me to the next page, which sucks. I would prefer to just be able to disable it entirely. Thanks!

I swear to god I used to have it disabled, just need to work out how again.

When I go into fullscreen on firefox macos, hovering near the top shows the traffic lights (fullscreen, minimize, close window buttons) and moves everything down. This may be expected behavior, but it is very annoying as when you try to open new tabs the tab bar moves out of the way of the traffic lights, and the traffic lights area is around the size of the tab bar. Is there any way to make the traffic lights always visible or keep them from moving?

Running WIN10. I have used FF w Google for about 20 years, and always had new searches open in same window, new tab. Following recent refresh of FF, that seems to be not possible. Links open in new tab, but not searches. In about:config the browser.search.openintab setting is True

I have closed and reopened FF, and closed and reopened WIN10.

What might be over-riding this? Many thanks!

Hello,

Recently I rebuilt my Widows 11 laptop, which meant that I needed to install Firefox again. I did this and signed into to sync all my add-ons again. The add-ons installed without issue, however the icons for them are not displayed on the tool bar. I can access them using the jigsaw icon, but this is is less inconvenient that accessing the add-on directly.

I then reset Firefox in case it was a glitch and signed in again to allow the sync to reinstall the add-ons. This time only the Privacy Badger icon made it onto the toolbar. Again I can access the add-ons using the jigsaw icon.

I have tried to add the add-ons to the Customise Toolbar setting, but they do not show up in the list of things that can be added.

Firefox version: 112.0.1 (64 bit)

I have attached images to show what is happening. Is there anyway I can force the add-on icons onto the toolbar to make them more accessible?

Thank you

Preamble: for most of the day I have Firefox open with several tabs. For a specific project I want Firefox open with one tab showing a specific webpage. At the same time I don't want to delete the existing tabs in the existing instance of Firefox - I want to keep them running in the background. Question: how do I create a desktop shortcut which opens a new single instance of Firefox with a single tab showing a specific URL ?
