Firefox supportforum

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.

Good morning, I have strange issue. Websites on my Manjaro Linux (GNOME desktop enviroment, using Wayland and Xorg) are not displaying correctly. Sometimes there are white fonts on white background-color, sometimes black fonts on black background. Sometimes where the bg should be white, it is black. I have Firefox Sync between my firefox browser on Windows 11 and Manjaro. Every setting in both browsers are the same. I tried to follow the instructions, like removing history, cache, cookies, turning off hardware acceleration etc. I just have no idea what to do now.

using firefox version 109 and my internet down load manager no longer works, it works in other browsers but not since updating firefox. not sure if i was successful in posting this request prior to this one so will give it another try. thanks

I upgraded Firefox to 109.0 on OpenSUSE Linux today as an update. Firefox no longer plays videos. Chrome is still playing the videos, so the codecs are on my machine. Is there anything I can do to fix this?

WHERE IS MY BOOKMARKS TOOLBAR??? Every time I update Firefox (now 109), I end up with all kinds of problems! NOW, I can't see my bookmark toolbar. All the help articles tells me how to show it or how to bookmark a page, which I already did multiple times. But this issue is never solved. If I can't get this resolved, I'm going to MS Edge.

So I wanted to read PDFs trough firefox with a dark theme, looked up how to do so online, and people say to change the "about:config" option "pdfjs.viewerCssTheme" to "2" instead of "0", I did that, tried opening a PDF, nothing happend, it was still black text on white backgrounds. Tried closing firefox, reopened the pdf, nothing happened, still white backgrounds. Tried to check if it might have to do with that specific pdf file's config, created my own PDF file from a word document, tried to open it, still white backgrounds. Tried disabling extensions, (which I use four of, UBlock Origin, SponsporBlock, Return Youtube Dislike and Translate this page), didn't work. Tried enabling the option on my laptop, didn't work. Tried a bunch of other stuff and it still won't work. My Firefox version is 109 and I'm using Windows 10 I also don't want to use the console/file edit thing with grayscale(1) invertcolor(1) or whatever it was since it also reverses the colors of images instead of just the backgrounda nd text color.

My extensions take up a lot of space in my toolbar and I'd love to hide all of them. However - every 'solution' to the problem tells me to right click the extension straight from the toolbar and click 'Hide from Toolbar'.

I do remember this option existing, however I couldn't find it since last update and I'm assuming it was removed. Is there any way to use it again?

^ (Small note, It would also be lovely if I could add them to the Extensions add-on in the toolbar, as that would really be a better use for it other than overflow)

Every time I come across a file and click the link to either open or save the file, Firefox just downloads the file -- THEN it asks me if I want to open it or save it..? It's bugged and an obscene security threat if the browser is so easily willing to download files against my intention.

Before I'm asked, I have gone through the settings multiple times to ensure 'Always ask you where to save files' and 'Ask whether to open or save files" are checked. Behavior does not change according to settings.

Example 1. Click link for a PDF with the intention to open, read, and forget 2. Firefox automatically downloads the file to my download folder 3. Firefox prompts me if I want to save the file or open it

If I click 'open', the file stays in the saved location even though I don't want it to exist.

so, my computer is getting old, and because of that, it's slowing then. Firefox isn't helping much because it uses too many processes and memory. i tried deleting some extensions, I tried using task manager to close separate processes but i always end closing the wrong one and closing firefox completely i tried going to dom.ipc.processCount and change the count to 1. I'm so confused, it's slowing down my games i play.

I tried to Connect Dropbox to my desktop, but the page would not load.

Chrome has no problem loading the page.

Could someone please let me know if they have the same problem

So this crazy new update has broken my Firefox in these ways:

1. All my bookmarks on my bookmarks bar have been deleted. 2. I can't drag any new links to the bookmarks bar 3. Overflow menu for apps is empty and will only let me drag Firefox defaults to it such as settings. Dragging apps to it is impossible. It "is" possible to pin items by using the Chrome puzzle piece..

Firefox: 109.0 OS: Windows 10 Pro

Using troubleshooting mode has no effect.

I recently updated my system (OpenSuse15.4) which included a Firefox update to version 109.0.

I regularly use my mic for google voice, however even though I can select my microphone in Google voice, It never shows any input.

I tested my mic in other apps and it works fine. When I pull up my systems pulse audio volume control (pavucontrol), it does not show firefox in the recording tab like it used to when using Google Voice.

To test to see if it was a Google Voice error, I also tried testing my mic at https://mictests.com/, and zoom.com, but after selecting my desired input device, mictests.com was also unable to record anything, and again, pavucontrol did not show anything being recorded.

I have attached an image of pavucontrol that shows audacity recording audio. Normally, I would also see Firefox in this window when using the mic.

I have tried watching videos through chrome and other browsers by searching something via duck duck go and watching that video on duck duck go, and it works on other browser so it must be specific to firefox.

Whenever I try to watch a video, in the drop down bar firefox select to mute audio for some reason. I then select 'allow audio and video' and refresh the page but the video is still muted for some reason. This also happens when I try to use other video sites. This has only started to happen recently in the past two days (and yes I am updated to the latest version of firefox).

Hello, when I'm on a website that could use my microphone or camera, I am not getting the prompt to ask for permission to use them. I have tried manualy giving the website permission in CTRL-I website settings. But that did not fix it. I have tried the same websites in google chrome, and my mic works then.

Via google search, I clicked on https://company.bk.com/pdfs/nutrition.pdf, where it said: Invalid SSL certificate Error code 526 Visit cloudflare.com for more information.

[FYI, I don't care, but I never heard of cloudflare.]

I then click on 'additonal troubleshooting information.' on this failure page where it says:

Error 526 occurs when these two conditions are true:

   Cloudflare cannot validate the SSL certificate at your origin web server, and
   Full SSL (Strict) SSL is set in the Overview tab of your Cloudflare SSL/TLS app.

Resolution

For a potential quick fix, set SSL to Full instead of Full (strict) in the Overview tab of your Cloudflare SSL/TLS app for the domain.

So I go to Settings>Privacy and Security. First, no Overview tab. But under enhanced tracking protection, I have Standard selected and with strict one of the options, I think I'm where I supposed to be NO!. So I search for SSL, and there are no hits.

Thus I am in a total failure state, unable to do what should have taken 1 minute to easily find out!

WHY CAN'T I JUST TURN THIS OFF FOR THIS ONE INSTANCE???? I mean, it's Burger King, and all I NEED NOW is nutritional info for what I just ate and there is no way on that results page to temporarily turn off the problem. Cloudflare? CloutFailure is more like it. They have taken my choice to choose!

This so frustrating, such a simple thing, why isn't there something to temp turn off?

https://addons.mozilla.org/en-US/firefox/addon/lightorange-on-black/ there seems to be a problem with this theme, cant install, cant upload or anything it says its corrupted can someone help? please contact me under my email [email removed from public]

When I open Firefox it's just a black page and anything I click on isn't responsive. I can't go into options or anything. Sometimes Firefox doesn't even load. It worked fine earlier than all of a sudden It stopped working today. Web pages don't load. Nothing works

I seen a post earlier that had a link to a supposed fix but I couldn't figure it out. So if anybody is able to help me it would be much appreciated. I am not an advanced user when it comes to Firefox

I found a really unusual behavior.

If I close Firefox using the "x" at the top right of the window, the Windows default for close, it does not restore session no matter what I do. I can manually go to the settings, history, recently closed windows, and restore them from there, of course - but that is a definitive hassle.

Strangely, even if I open up a new tab less than 2 seconds before I hit the X to close, it will not restore the session but does indeed save the new tab to the previous.jsonlz4 file, and makes that available via going through the settings menu.

What is oddly more unusual is that if I close Firefox by way of ctrl-shift-q, it works fine (opening Firefox after ctrl-shift-q restores the session without any extra intervention required).

How do I make Firefox recognize closing via the bog-standard-since-windows-3.11-for-workgroups X in the top right of the window as properly closing/quitting?

Hello,

There is a very long list of these that are associated with my account. I've imported my Firefox settings from computer to computer for at least twenty years. I may have made mistakes that caused me to pick up malware, and want to fix this, and some of these certificates have expired.

How do I know what to keep and what to either delete or edit trust regarding?

Is there any way to quickly and easily have all of them assessed at once?

Thanks very much!

Sally

I asked this a couple of years ago - ! But the problem apparently is BAAAAACCCKKKK.....

In my list of bookmarks I have inserted SEPARATOR lines. I cannot find how to delete a separator line. There doesn't seem to be any up to date information online about how to handle this - can someone help?

In the previous fix I would click the three-line icon at top right and to into MANAGING BOOKMARKS, where there was a way to see the list, and I could click on and delete any separator lines I wanted to remove.

Apparently in the newest version of FF this no longer works. Now when I go to Manage Bookmarks, there is a list of my bookmarks, but I don't see any of the separator lines.

I'd be truly grateful for help - thank you in advance.
