While trying to work on some issues and experiment, I noticed that the web tests no longer work on recent versions of firefox (as you noted in the readme Brett). It seems like there are some incompatibilities between firefox 18+ and recent versions of selenium.
I was able to run the suite successfully by downgrading to firefox 17. However, it appears from the changelog that recent versions of selenium should be supported: https://code.google.com/p/selenium/wiki/SeIDEReleaseNotes#2.3.0 Since remote control is deprecated, I am wondering if it might make sense to try and migrate the web tests to web driver. One thing I noted is that supporting tests for multiple browsers appears to be a bit more difficult with web driver vs remote control (since it used injected JavaScript). At present, how many browsers are we typically running the tests for? Thoughts? Brent
