Using Windows 7 pro with Kaspersky anti-virus. All I had this morning when opening firefox was a blurred outside screen with no data in the middle box area. Nothing works but the min/max/close in the upper right corner. Clicking on the firefox icon there is message "under construction". I've uninstalled and downloaded severakl time but get the same non-working screen. How can I be sure the old defective firefox is gone and that I'm downloading a new copy ?

hello, other users with this problem all had an embedded intel hd graphics card with an old driver present. in case this also applies to you, here would be a link to update the driver, which in turn should also address the black firefox problem.

Intel guide to find out which model you're using

in case this doesn't solve the issue or does not apply to your system, start firefox into safemode by pressing the shift key while the application is launching & disable hardware acceleration in the firefox menu ≡ > options > advanced > general (that setting will take a restart of the browser to take effect).

For some reason unknown to me I reloaded Firefox after this message and it loaded and performed normally.
