I'm happy to update you that QTPWEB_00092 (Add Support for Firefox Versions 9,10) patch for QTP 11 was recently verified with Firefox 11 as well.
Note : QTPWEB_00090(Add Support for Firefox Versions 4 Through 8 ) patch has to be installed as prerequisite for QTPWEB_00092
I had to install patch QTPWEB_00105 before Firefox would allow me to enable the QTP plugin.
But it doesnot support FLex in firefox ??
Does QTP 11 supports html5 in FIrefox ?
