Comment by myonceinalifetime: Basically, the web app runs exactly the same regardless of whether or not the plugin is installed (both FF and IE). Thus it is behaving the same as when using hosted mode in GWT1.7.1 but putting the address (http://localhost:8080/myproject.html) in an external browser (try it, you can use the web app perfectly fine, it just won't hit any breakpoints that way).
I just tried out GWT2.0 milestone 1 and it's the exact same deal. It is supposed to launch FF but it doesn't, doesn't even create a new tab. I tried it without the plugin installed because GWT2.0 is supposed to download and install the correct plugin "the first time you use development mode in a browser that doesn't have the plugin installed" but it did not. I had been using Eclipse 3.41 but now I am using 3.51, which has not made any difference. I don't know what could be different about my situation compared to anyone else doing OOPHM on windows. I don't suppose it's because I'm running Vista (32bit) is it? I hope someone might be able to help me with this, because the complexity of what I want to debug is too ridiculous to attempt with window alerts.
