Firefox Support Forum

Hi Firefox start to take a lot of CPU depending on how many tabs are opened (that is normal of course especially if with flash contents). What is not normal is that CPU will not be released when tabs are being closed, even with one (blank) tab left opened CPU usage is 40%-85% (depending if other process need CPU). Essentially: once Firefox process obtained 80% of CPU you can close tabs but you are fucked the same, now opening new tabs is a pain! Of course restart fix the issue. Is not a matter of addons or updates, Firefox and system (Windows 10) are updated to last version; I feel is something related with flash contents. Is it possible only me experience this?! Regards

Hi! I found a strange thing today. I wanted to open an ftp link and firefox asked me in which app I wanted to open it. Of course I wanted to open it in Firefox, but the only app on list was Internet Explorer. So, I added Firefox to the list, but I couldn't open the link with it, because when I marked Firefox and tried to click "open", nothing happend and the box still appeared. So, I ended up using IE. I'm using Firefox Nightly (81.0a1 atm of encountering this).

I am using Firefox Browser V81.0 (64-bit) on MacOS Catalina and I'm experiencing issues with downloading files specifically from Google Drive. I can download other files using Firefox, but it doesn't work when using GDrive. I know it's an issue with Firefox because I've tried downloading the GDrive files using Safari and it's fine.

What happens is I'll click download and then there is no prompt that asks me if I'd like to download the file.

I also looked at this thread and followed the troubleshooting measures (including clearing the browser cache and starting Firefox in Safe Mode), but it did not solve the problem: [https://support.mozilla.org/en-US/que.../1157677]

I've also tried un-installing/re-installing Firefox. And I have my adblocker disabled for Google Drive.

Any suggestions for how to resolve the problem?

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)

just yesterday i noticed that when i had any audio playing in firefox, the title shows up next to the volume meter when adjusting my computer's volume with keyboard keys. spotify used to do this when i used to use it and it was a pain to disable it. how do i disable it in firefox

I have noticed a new folder has appeared on my desktop - out of the blue - labelled "STG-backups-FF-81.0.1" If I delete it, it is simply replaced by another one at some point, later on. I assume this folder is created by Firefox and the back-up file information is saved in it automatically. Surely the folder should be in a different location? Has anyone any ideas on where this is supposed to be, and how to get Firefox to revert to saving the files in it in the correct place?

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.

I've been using Firefox for many years, and search results have always opened in a new tab by default. Now, with Firefox 81.0.2, they're opening in the current tab, and I can't figure out how to get back the old way. Does anybody know?

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.

I am a home user with win 7 OS. In the DNS over HTTPS FAQ it says that

In addition, Firefox will check for certain functions that might be affected if DoH is enabled, including:

   Are parental controls enabled?
   Is the default DNS server filtering potentially malicious content?
   Is the device managed by an organization that might have a special DNS configuration? 

If any of these tests determine that DoH might interfere with the function, DoH will not be enabled. These tests will run every time the device connects to a different network.

Is there any way for me to find out if DOH is enabled or disabled by Firefox?

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 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!

Every time I restart my pc and load google it asks me to 'agree' to their terms. It does not remember that I have done this and forgets the options I chose. It is just annoying having to click on it each time. I found an article online but it must have been applicable to an earlier version as when I go to Options > Privacy > History section there is no longer a button on the right "Exceptions..". I am using version 81.0.1 (64 bit). Any help appreciated. Thanks

On this page

 https://support.mozilla.org/en-US/kb/secure-firefox-account-two-step-authentication

it says

 5. Use the app to take a photo of the QR code, or click Can’t Scan Code to display a code to enter into the app. 

But I don't see a QR Code anywhere. What am I missing?

Thanks.

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.

Is it possible to import my Opera bookmarks into Firefox? The only selections I've found in the Help file is from Microsoft Edge, Edge Legacy or Internet Explorer. Perhaps there might be a workaround?

I am posting this question to offer a solution to the problem I experienced. My firefox bookmarks were not immediately syncing across accounts. Once I added a new bookmark on the browser that was not showing the bookmarks the synced bookmarks appeared. This may offer a solution to other users.
