After this driver update Firefox has several problems
a. will not play videos in You Tube
b. when i go to any page related to Mozilla i.e. add on page , support . help ,the page is displaying HTML content ,text only
c. sometimes i get an error message while navigating " unsecure connection"
I understand there will be another win 10 driver suite released on July 29 with the release of Win 10,and that it is complete , i hope that driver resolves this issue ,if not i will re post here.
