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?

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!

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.

I was gifted an Amazon Fire Tablet to use for an upcoming hospital/rehab stay. I use Firefox on my desktop and Android phone and want to use it on my tablet, but the Amazon store doesn't have the app. Not sure I trust the Amazon Silk browser, but I may have no choice. I am not a tech savvy person! I don't know the difference between a bit, byte, or buttercup. If there is a way to install and use Firefox on my tablet, and sync with other devices, I would like to do so. Please explain how to do it as though you are talking to a 6 year old (who probably knows more about this stuff than I do, anyway). Thanks. rennylloyd

I'd like to hide the title bar in Firefox. It takes up valuable on-screen real-estate, and doesn't really serve a purpose (other than showing a web page's full title, which I'm not interested in anyway).

In this screenshot, I have Firefox on the left, and Brave on the right. Now, I know it's only about 30 or so vertical pixels, but the title bar in Firefox is taking up a lot of space that could be used for actual web content.

Is there any way to disable this top bar? Or is it baked into the actual program itself?

Hi !

Ever since I received my bluetooth headphones (ATH-SR50BT), I've had a problem with the sound. Whenever I pause a video or kill the tab it's in (even if the video is not playing) all the sounds of my computer are muted. Simply changing my sound output and going back to my headphone resume the other sounds.

I've tried solutions for Windows and the headphone without success, and then found solutions that appear to work for Chrome (https://support.google.com/chrome/thread/8894867?hl=en&msgid=14396047) and Spotify (https://community.spotify.com/t5/Desktop-Windows/Pausing-Spotify-Playback-quot-Mutes-quot-ALL-Audio-Playback-On/m-p/4551102/highlight/true#M64084), hence why I decided to search for a Firefox fix.

Could someone help me ?

Since a few days I noticed on two different windows 10 PCs that firefox keeps signin out of websites (yahoo, linkedin etc), and this happens semi-randomly but sometimes more than once per day. My security settings never changed, I did configure firefox to delete history when closing, but preserving cookies and active logins. I also tried to add those websites to trusted sites (in the tracking menu, the shield to the left of the url). Any advice?

Today I got what I've seen described as the "Facebook White Screen of Death". I've tried: Reload Clear Facebook cookies (which implies logging back in) Clear site data Restart in Safe Mode None of these things make any difference. Still get only a white screen. Facebook works fine in the Chrome browser and in the Android app, so it must be a Firefox-specific issue, in my case. This is Firefox 81.0.2 under Ubuntu 20.04 The problem only started today. I've used Facebook with Firefox for years without problem.

Hello at the forum!

I used seamonkey for years and it doesn't work as a local email program for me anymore.

I can't configure it to my yahoo/att (pacbell.net) email anymore, would rather do that but...

So I downloaded Firefox to use for a local email/browser. I like having emails on my local pc.

Where do I find the email program on my Firefox and how do I set it up?

I go back to Netscape 1.0

Thanks for any help! ~Kirch

Honestly, I have no idea how to describe it. I loved how when I played a video on Firefox, it wouldn't pop up with that annoying video title whenever I changed my volume. Now, when I'm watching a video or playing audio, this happens. And, it doesn't even get it right most of the time! Like for example, it does this instead! That's not even the page I'm on!

Is there any way for me to get rid of this? Thanks
