Experimental Features

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options) key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

Is the problem still there?

See if there are updates for your graphics drivers https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration

Starting in Safe Mode works great!

With Graphics Driver, it says it has the latest version!

hi, here should be a driver update for your graphics hardware: https://downloadcenter.intel.com/download/26228/Intel-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-40- (using windows update to search for newer drivers won't work in most cases).

win32 Got error: This installation package is not supported by this processor type.

Tried win64 Got error: The driver being installed is not validated for this computer. Please obtain the appropriate driver from the computer manufacturer!

ok, then i suppose you are using a notebook and it's manufacturer has disabled the option to install generic intel drivers. so your remaining options would be to disable hardware acceleration in the firefox menu ≡ > options > advanced > general (that setting will take a restart of the browser to take effect).

Nope. Resizing the window also shows the problem.

after a restart as well?

worked!

so sorry. i closed one window. there were some others open! :(

thank you so much really appreciate it.
