Have to tried reinstalling the firefox or just disable all adons then try and do clear the cookies and cache.

Hello dark_shrouds83, if you [[Upgrade your graphics drivers to use hardware acceleration and WebGL]] probably you are ok without the issue any more. '''As a quick fix (if you do not want to upgrade your graphics drivers), try disabling graphics hardware acceleration in firefox. ''' You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.). Then perform these steps: #Open Firefox ''Options'' window (''Preferences'' on Mac or Linux) as follows: #* In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]] and select ''Options'' for Windows or ''Preferences'' on Mac or Linux. #* In Firefox 28.0 and previous versions, click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options. #In the Firefox Options (or Preferences) window, click the ''Advanced'' tab, then select ''General''. #In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox. #Now, restart Firefox and see if the problems persist. '''In safe mode, except the extensions, and hardware acceleration is disable''', that's why when you are in safe mode your issue not exist. Thank you.
