Firefox Support Forum

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 ?

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 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?

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

The address wasn’t understood

Firefox doesn’t know how to open this address, because one of the following protocols (fb) isn’t associated with any program or is not allowed in this context.

   You might need to install other software to open this address.

How can i fix this?

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

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?
