Can I turn off the "control media playback via hardware media keys on a keyboard or headset or virtual media control interface" function? (Firefox 81.0, Windows 10)

Hey there, awesomes! I'd like to change my Firefox pdf viewer's background color (both sides of the pdf) to dark, currently it shows light gray (see `background_bg.png`). And here is effect I want it to look like (see screenshot from Chrome `wished_bg.png`). Thanks in advance (:

PS: I don't want to change my theme to dark. It seems I have to change my css, but I dunno which & how.

Hi

For two days I've been searching on the web and in here with no luck.

Initially as Facebook is loading ... I can see the video for a brief second, then its turns grey with the message "Sorry, we're having trouble with playing this video."

Appears to only be a problem on Facebook and only in FF (chrome facebook videos work fine)

Using

FF 81.0 (64-Bit) Windows 10 Version 2004

Tried with all addon's disabled. Tried with anti virus disabled

Tried adding "Flash Video Player for Facebook" addon

Videos all work and play in chrome.

Hi, I faced the problem with Youtube recommendations on a video page. When I watch a video I can't see recommendations, comments and video title (see the image). In console i get an error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://googleads.g.doubleclick.net/pagead/id. (Reason: CORS request did not succeed).

I am on arch linux system.

I've tried to: 1. Update all ca-certificate* packages 2. Disable and delete ad-block 3. Use another browser (there is no problem, only in firefox)

This problem is only actual on Youtube for me.

Ever since IE changed to tabs on top firefox coders followed like mindless automatons without any regard to/for Mozilla community and users. We are sick and tired of being ignored. We want/need tabs bellow address bar. Now, tell us how to simply get tabs below address bar or tell the coders to provide us with the option. And, we don’t care about any excuses as previously provided or outright ignored by them.

Hi all,

I've been having problems with firefox lagging constantly. General browsing around feels laggy - and opening new tabs pretty much causes my computer to freeze for a few seconds. During this time firefox causes the CPU to spike to 100% usage.

I've been using firefox for years on this computer with no issues. Hardware is pretty good (i7 5820k, 64GB of ram and an SSD).

So far I have tried:

• Running in safe mode

• Using a different profile

• Downgrading to an older firefox

• Changing allowed CPU cores from 8, to 4

• Updated graphic card drivers to latest version

None of these work, and I'm getting a bit tired of the constant slow downs. Chrome works flawlessly, as does all my other software...

Any ideas?

Thanks!

I just updated Firefox to version 81.0 in Linux, Windows and Mac, but the credit card autofill option is still missing from the Preferences menu.

I followed the instructions from here:

https://support.mozilla.org/en-US/kb/credit-card-autofill

Yes, I am located in the US.

When I go to a web page which is a PDF, the web page used to load as a PDF. Now there are 2 tabs, one is blank and has an address which refers to the PDF location, and the other is a PDF saved to the Temp folder (eg. file:///C:/Users/USER/AppData/Local/Temp/some_PDF.pdf)

My preference is: www.some_website/some_PDF.pdf

This is because I save the tabs, and the next time I use Firefox, the temporary PDF is not loaded anymore. As well, I prefer 1 tab instead of 2.

Where is the setting to adjust?

I am trying to minimize Firefox, but the minimize icon in the upper right-hand corner is missing. I am still able to close Firefox using the 'X' in the upper right corner of the window, but I am unable to minimize or restore. All other applications still have these icons available.

Pausing and stopping video also stops music playing outside Firefox. If I click pause or end a video within firefox, music playing outside firefox using programs that are not firefox stops. How can this be fixed?

Why can't I use right click menu in Alert Dialog? I select the text in an alert dialog but when I press right click the menu will not show up. I works in Chrome. Why not in Firefox? Any way to have it work?

Hi! so I installed Kubuntu 20.10 after using it 'directly from the cd' for some time. since, all data would be lost every time i restart, i would keep a copy of a '.mozilla' file i would find in the system. Everytime i start the OS, i would first create a folder and copy paste it, so firefox would start right where i left it off. this worked, until i decided to make Kubuntu permanent. at first things were going good, but after sometime, my OS would stop recognizing my headphones and audio port completely. at first i blamed it on my OS and went about doing somethings here and there to adjust by. but looking back, i had installed some DRM to play some video on the net. so in a desperate fix, i replaced the current .mozilla file with a backup i had. the thing worked like a charm and my audio was fixed and everything was going ok, except for the occasional fixes so that my OS would channel the audio to the right output. that is, until the problem rise again! this time, i hadn't installed anything like i did previously, so i replaced the .mozilla file again and it worked! but i can't keep doing this and i had also faced the same problem in my windows, resulting my change in OS in the first place (I think its the same issue, because whatever i did didn't fix it and windows is more sophisticated that i wouldn't know). I don't know if this much info is too much or too less or that if i should post this here or in any other forums, but i would really appreciate it if i got a solution! Thankyou!

Hi all,

Since a few days Firefox is so slow that I decided to switch to Edge and Chrome. Any idea what's up and how to come back to "normal" performance.

Kind regards, Tilman
