The 3 bugs mentioned in the previous post occurred are firefox portable (you find in desktop folder with this firefox portable) while today it occurred with firefox installed in the virtual machine the bug of the multiple tabs of open firefox, now I create the video.
The bug of multiple tabs open is random does not always occur I have carried out numerous tests, I leave the 4 and 5 video in the desktop of the virtual machine so you can view it and you can also see the code of the macro used, it does not always occur so you have to try more times (perhaps with a batch file that opens and closes firefox).
4 video firefox installed open multiple tabs with command “selectWindow” (see 1 video firefox installed in desktop virtual machine).
5 video firefox installed runned via command line batch file with closebrowser1 and close Kantu1 do not work and firefox cpu go 50% after manually closure firefox crash (see 2 video firefox installed in desktop virtual machine).
To see video use Vlc portable please continue if you see any error (probably codec missing) but the video play regulary.
I continue to test and report bugs.
