Hi! I'm a software tester and I was running a test using Firefox 3.6.12. In the middle of the test I logged off and went home. The next morning I logged in and FF automatically updated to 3.6.13. At this point my silverlight plugin claimed to no longer be available and so I uninstalled and reinstalled silverlight. Same issue; my computer thinks that silverlight is not installed. Under normal circumstances I'd contact MSFT regarding silverlight, since it seems to be a compatibility issue, but the first order of business - since I am after all testing software - is to try to reproduce the conditions under which it was working before the update. Can anyone tell me where I can download FF 3.6.12?
