Today, I had the chance to do some more testing with simplespy.au3:
I used machine #1 with 64bit Windows 7 build 7601 and almost current Firefox 68.0 64bit
I ran the same tests on machine #2 with 32bit Windows 7 build 7601 and current Firefox 68.0.1 32bit
Same Tests were made on another machine #3 with 64bit Windows 10 1803 and current Firefox 68.0.1 32bit
More details about my environment:
All machines have German versions of Windows and Firefox.
On the 64bit machines #1 and #3, I executed simplespy.au3 in both modes x86 and x64, using "Run Script (x64)" and "Run Script (x86)"
During the tests, Firefox is already started when I run simplespy.au3
I have to confirm an UAC Dialog, before simplespy.au3 starts
I have autoit version 3.3.14.5 installed on all machines
How I did the tests:
I can place my mouse over almost any Element of Firefox (tried toolbar, address bar, favourite bookmarks), press Ctrl+W and get information about that element in the simplespy window on any machine.
If i place my mouse anywhere in the content area of the browser (where the web content is displayed) and press Ctrl+W there, simpplespy.au3 crashes on machines #1 and #2 (with the additional information as shown below). On machine #3, everything works as expected.
Conclusion:
Access to content area of firefox doesn't seem to be possible with windows 7, but works fine with windows 10
Do you have any idea what's going wrong with Windows 7?
