I just formatted and installed Windows 10 (Pro N, 64-bit, 1909 update) and then installed firefox.

To my surprise, no videos can be played on any website (except youtube).

The video either doesn't load or shows the "Error loading player: No playable sources found" error.

I had no extensions installed, tried refreshing, tried disabling hardware acceleration; nothing solved it.

All content plays fine on chrome.

Firefox slows down or even freezes for a longer time when I am typing in text in forms (like new GMAIL messages, search boxes, etc). Especially when I make mistakes and delete some.

I have Refreshed Firefox and removed the Adblocker add-on, which I thought might cause the problem, but the problem persists.

Any idea how to tackle this?

Hi there,

Occasionally (every half hour or so) I will notice there are two Firefox browsers open (I use nightly), one which I am using and another that fills half the screen but is stuck as if it were trying to load up. It cannot be closed or minimized unless the 'Firefox has crashed' message pops up, I was wondering if this is an issue faced before and can be fixed or something new?

Thanks

Firefox is crashing almost immediately after loading a page. Sometimes it crashes while loading the page, sometimes I can scroll down or click a link, and then it crashes. Biggest issues are on Reddit. I'm able to browse the Firefox support pages with minimal issues (although it has crashed once or twice).

Crash happens in Safe Mode. (I'm in safe mode right now and it just crashed) I did a FULL clean install about a week ago. (actually did it twice just to be sure)

Not sure what info you need in order to help, but here is some of the crash report from the latest one today.

I have noticed that after using Firefox for a while when I close it the trace is left of the page I been watching or working in. Mainly it is visible through transparent windows (visibility stays after the Firefox window has been closed) and when the desktop background is changed to a dark blueish colour I can clearly see the faded Firefox page. Restarting PC changes nothing, the faded trace stays. It clears out after not using Firefox for a quite while. I really enjoy and prefer using Firefox to other browsers but this problem has been annoying me for a some time already. Any suggestions for fixes ?

I use Firefox as my business email and all was working fine until I upgraded Firefox using my Safari browser and created another login profile based on my personal email. That's when the error 'a copy is already open' began. To solve it, I did the above and had two profiles a 'default' and a 'default-release'. I believe I deleted the 'default', and the problem remained. Then I tried a reinstall, and I suppose that's the 'default-release-1' profile, but I really have no idea. The problem for me is that I need to import bookmarks, the business email account linked to Firefox and Host Gator, and all my LinkedIn, MailerLite stuff. I do not want to lose all this and just do a clean reinstall. However, now because I can't open any version of Firefox, I have no way to access the business emails, etc, so I can't recover the Firefox account linked to this business email and get all this stuff back. And I don't know which of the above three profiles I need to delete to get it all working again. Please help!!!

Hallo, since I've switched from InternetExplorer to FireFox as the standard browser, I cannot open MHT-files which I downloaded from the web. Firefox starts to open new tabs, by the second, endlessly. The process can be stopped only by killing Firefox with the TaskManager, several times. Is this a bug or a feature? Many thanks Ante

Hello!

I am using Firefox on my notebook with external monitor.

When the external monitor is set up as the main display and above the notebook monitor, the toolbar popup menus in Firefox are cut off on the notebook monitor (≡ & addons like uBlock etc.), so only a small upper part of them is displayed. The ≡ menu can be fully operated in this case because it has scroll bars, the addons' menus do not.

If the notebook monitor is set up as the primary monitor or is not below the external monitor, the problem does not occur.

Disabling all addons does not cause any change.

The problem does not occur with other browsers either.

Would appreciate some help!

I have been experiencing lately quite few Firefox crashes that bring down the entire (desktop) Windows OS in a brutal manner: complete system lockup, instant reboots (no blue screen).

These seem related to the audio and video interactions with the host system - streaming musinc online (siriusxm.com) or engaging in graphic intensive activities. This supposition propmpt me to perform few hardware tests - memory, GPU, audio card,etc. Everything checks out fine with the basic test and diagnostic tools I've used.

The worse system crashes have happened while on the https://buckhill.com/tubing-2/snow-tubing/ wesbite trying to purchase passes. Along the way for signing the waiver, the site brings up a graphical pad for capturing the guest's signature using the mouse. Several attempts have ended with horrendous system crashes (I had to locate the hardware reset button on my system, which took a while), never in the same spot in the process. Similar issues have happened on my wife's laptop (Windows 10 OS) while using Firefox on this site. I had to use a different browser to complete this purchase, for both my kids sanity and my system health. (for whomever is interested in troubleshooting this site, just follow the prompts and add guests - the purchase step is the very last one).

I should mention that Firefox' own crash page (about:crashes) shows no sign of any crashes. Other times, the Firefox window just dissappears without any warning, and no traces of crash information in Firefox nor OS event system. My system is configured to save a memory minidump in the event of crashes - there were none.

In this context, I could be wrong, but narrowed the culprit down to Firefox itself. In my opinion, whatever Firefox is doing to bypass OS basic protection mechanisms (and let's be honest - on Windows these can be better) and cause such hard failures are a dangerous vulnerability that should be investigated.

Any ideas and suggestions on diagnosing this or what to capture for aiding with troubleshooting, are appreciated.

Hello!

I can't use Netflix on my old Windows 7 machine. I'm sure my computer can handle the transcode but just in case - it runs an i3-2330M with 6GB of RAM. When I hover over a title, I can see the preview but when I click it, I end up with an error message. I run the latest Firefox version and have also restarted to check if it works but alas, to no avail.

I have attached an image below. Also, just in case, I have done the adjustments to Firefox's configuration from here.

All help would be appreciated!

PS. Not sure if this helps, but Firefox couldn't play Spotify either! When I open the web Spotify player, I can see my playlists and such, but when I click on any song/album/playlists's play button, it doesn't respond at all! I have resorted to using the app, but am mentioning just in case if it helps figure out the problem/for other users having the same trouble as me.

i've been having specific issues with firefox with audio files, seen in example on some specific websites where audio will refuse to play. this is not the case on other browsers on my computer, where files will play perfectly fine.

i've found this is the case on both the osu! website (the popup audio player will appear at the end of the site, audio unplaying) and the bandcamp website (bandcamp player attempts to load audio, shows loading screen, then skips to the next track). i've only experienced this not happening on soundcloud, although there are probably more examples out there for both working / not working cases. does anyone know a fix?

First of all, my request concerns the "Free box TV" function or button or application of the Freebox server web interface running under OS version 4.2.7 with the default browser Firefox 84.0.2 (64bits) which allows to watch or record freebox TV channels on PC. Malfunction observed: After uninstalling "Adob flash player" dated January 13,2021 and upon the requested installation of VLC 3.0.12 with web plugin, Mozilla plugin and Active X plugin activated, it is impossible to open the "Free box TV" function or button or application. Indeed a double click on this button invariably leads to the edition of the message: "impossible to watch TV, you must install " flash player "plugin (which no longer exists since January 12,2021)or the VLC plugin which is a NPAPI one (not allowed by Firefox). Everything happens as if the installation of VLC had not been detected. I tried with 2 other browsers: microsoft Edge and Avast secure browser with an identical malfunction NB: the VLC player works nominally and allows to read the TV network stream from the freebox server. Questions: Q1: Do I have to install the extension or the module "Open in VLC media player" in the Firefox browser in order to open the "Freebox TV" application? Q2: Do I have to wait for a further Freebox development of this function which would be based on HTML5? with my thanks

Hello, for the past week i've been tackling this problem and it's driving me nuts. I've basically replaced FF with Chrome at this point, because I can't use it for work.

Firefox refuses to print, no matter which printer I select, and even if I try to print to .pdf using Microsoft Print to PDF (or other, 3rd party ones, I tried). Other programs and browsers print just fine, it's only FF that refuses, and it refuses to do so with any printer, physical or virtual.

The error I get is a window titled "Print Preview Error" and the error message is "An error occured while printing" (see attached image). For what it's worth, when I go to the menu and select Print, I get the print preview just fine, it's only after I move on to the printer selection and click on Print that I get this error.

I've followed all the steps from: https://support.mozilla.org/en-US/kb/fix-printing-problems-firefox as well as: http://kb.mozillazine.org/Problems_printing_web_pages#Reset_printer

And I've also tried using Safe Mode while doing that, as suggested here: https://support.mozilla.org/en-US/questions/854093

I hope you can help! I've been a Mozillian for more than 20 years, contributor, and volunteer, but this is making my work impossible and I'm forced to abandon FF due to this problem.

I have a VMware VM used as a desktop by a team and they've reported that Firefox only shows a blank screen. It doesn't respond to anything, if I click the burger and click options then it doesn't even open a new tab. And I can't even access about:config.

However I've discovered that if I access the desktop via the VMware console then FF works perfectly fine, if I RDP onto the desktop and run FF I get the behavior as I've described.

Even weirder...is if I launch the browser in an RDP session and then seize the session via the VMware console then the behavior stays there until I relaunch it.

And vice versa if I launch the browser in the vmware console and then log in via RDP the browser works perfectly fine until I relaunch it!

What could be causing this?!

I've tried: Disabling hardware acceleration Cleanly uninstalling Reinstalling both the latest version and latest ESR Removing my profile All resulted in in the same blank FF.

No other VM running FF is experiencing this issue, and I'm the only one with rights to modify things.

Any help with this would be greatly appreciated!

Hi, I just installed FireFox on my Early 2011 MacBook Pro, and every time a page loads up, the screen flashes and flickers with long horizontal bars. It's not just the browser bar, it's the entire screen, and it's making FireFox unusable on my laptop. I tried changing the hardware acceleration, which reduced the amount of flashing but did not stop it from happening. I also tried running FireFox in safe-mode but I am still having the same issue. Any ideas on how I can fix this?

I have tried the existing recommendations to delete item(s) beginning with print_ that had no effect. I copied prefs.js and removed all items beginning with print and replaced existing prefs file. Curiously that change worked at least twice before trying PDF print preview. After trying the preview the print function went back to taking 30 to 60 seconds to respond.

Print and print preview work fine in Chrome and Safari.

I have a macbook air and a new macbook pro. The macbook pro works well. I compared the config print items and found no obvious discrepancies. Both macbooks are on Firefox 84.0.2

My significant other blames Apple. I am convinced the problem lies with Firefox. Oh -- print screens are not worthwhile since we're talking a major time delay.
