When viewing a site that is using html title attribute such as http://xkcd.com (hover with mouse over the comic strip) the tooltips are not shown. In safe-mode they work.

Letting the safe mode start window reset everything does not help. Neither does completely removing the profile (C:\Users\<username>\AppData\Roaming\Mozilla\Firefox) and letting Firefox to recreate it.

In Firefox 4 and later Safe mode disables extensions and disables hardware acceleration.

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

Thanks, disabling hw acceleration indeed works!

Well, this is a company notebook with some fancy dual graphics, so while I have current drivers released by the OEM, I am not going to experiment with stock NVIDIAs current driver (which is indeed more recent).

For the records, this is a Dell Latitude E6520 with NVIDIA Quadro 4200.
