When we kicked off Flash Selenium, Firefox 2 and IE7 were the only browser(s) that we intended to support. But, the world moved on and most likely we did not. The scene was something of this sort:
Microsoft: IE 7 is awesome. We rule your world!
Mozilla: Firefox 2 is kick-ass. We'll take over the world with FF2.
Selenium: Oh yeah, these two are here to stay. I'm cool with both of them.
Flash Selenium: Thank god Selenium's got my back.
Microsoft: IE 8 is better than ever. Lotta ppl agree to this.
Mozilla: To hell with Firefox 2. We'll give out Firefox 3. A better, improved, cutting-edge browser full of c**p! We'll make hell lotta changes to the way things used to work with FF2 and how it'll work with FF3. You damn right we will, coz WE CAN!
Selenium: I'll patch myself to make things work for now. Man these two guys are driving me nuts!
Flash Selenium: zZzZZzz, drool....
FF2 used the document. notation while FF3 will use window.document. notation to refer to a document object. I still don't know why Mozilla ended up making this change but Flash Selenium went in for a toss.
The good news is that Revision 25 has the fix for Java and .NET Client of Flash Selenium and we'll fix the rest in few days.
PS: We appreciate the issues that have been logged by our users. Thanks a lot.
