I was watching a YouTube video and as I pressed the button to go full screen I saw a square pop up in the bottom taskbar, like where the internet explorer and spotify icons are at the bottom of my screen, by the Windows start button. When I exited the video it dissapeared, so it was only up when i was full screen, it was never up there long enough for me to click on it. It was all red except for an italic f, which was white. After I watched a couple more videos, an actual pop up...popped up and said it had a X and said that windows had some kind of run time issue. I x-ed out of that, did'nt press OK. I had read some things about the McAffee Security Scan Plus (which had installed with my adobe, just reinstalled it today....actually just got firefox today too-google chrome had not been working right for a while) and I decided to un-install that and it didn't stop the problem. I am wondering if this is something I should worry about? I'm not sure what it is and it has never appeared before. Please help!

Hello,

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:

  1. Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
  2. Under "Time range to clear", select "Everything".
  3. Now, click the arrow next to Details to toggle the Details list active.
  4. From the details list, check Cache and Cookies and uncheck everything else.
  5. Now click the Clear now button.

Further information can be found in the Clear your cache, history and other personal information in Firefox article.

Did this fix your problems? Please report back to us!

Thank you.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Firefox uses the about: protocol to access built-in about: pages that you can open via the location bar just like you open web pages.
