Firefox problem
 

For example, when i click on some game via FlashScore.com: Live Soccer Scores, Livescore
i get new window opened, but across hole screen.

Previously, it opened like nice little window (popup style), how to fix this?

ps - no help with fixing the window size, then closing window

i never incountered this issue with firefox. porbably go to settings ans allow popups

Not sure what the deal is. Im running the latest version of Firefox and no problems with oversized windows at all.

Try mousing the screen edges to manually make is smaller. Close the window and try re-opening the same window again.

Here is my view.

That was for me previously, but now i just get that new "popup" window opened in full size :( it's annoying as hell

It's hard to believe I can not find 1 Firefox support article on you situation.

I would do a System Restore from last week and see if that helps. :thumbsup

i don't use firefox anymore, my new fucking love is chrome

Chrome is better.

2 things come to mind but may be neither... Just things to check...

The page is being opened with default screen size fixed at a higher res than you are displaying. Check the web page source code.

OR

You registry is corrupt.
