Yesterday I was watching some youtube videos normally, today I went to see a video ,and nothing appears only a black screen without any button to see video
PS: I'm using Firefox
Install last flash player, if this does not help try another browser (currently, Firefox sucks balls, try Opera), if this does not help too, then get yourself last video drivers, but I'm sure that this problem is just because of flash player.
At least try to use another browser, such as Internet Explorer (for example). If video works fine there, then you will need to reinstall Firefox, because it was broken somehow. If videos still does not work, then I really have no idea, except updating the video drivers. Check "hosts" file in "windows/system32/drivers/etc" folder. Open it with notepad.
I see what you did there. Since when Firefox is good web-browser? Come off it.
Since Opera (My second one. FF is third. guess what first xd) caught some shit and goes to delete cookies after every login, which really suck, so i DL'ed FF and still using it.
I cant say what Opera suck, i still have it (among with Chrome, Safari, IE, Avant, Maxthon, SR ware Iron. Duno why i have all of them, even if i dont like those xd), but dont using it.
Easiest method would be to uninstall your current flash softwares: Adobe flash player and Shockwave flash player. and reinstall them by googling using keywords "Adobe flash player" and "Shockwave flash player" and it will all work again flawlessly. I had this issue before. It's easy to solve it.
OR!
Click on this,
Seemed to work with me when I had this problem.
(Don't know how to get rid of it, stopped when I reinstalled VISTA but I had to do that because of virus )
