The MinimizeToTray XPI claims it's valid for Sunbird 0.3. I think it's a bug with the setting of app.extensions.version Reproducible: Always Steps to Reproduce: 1.Download and install MinimizeToTray from http://downloads.mozdev.org/minimizetotray/minimizetotray/minimizetotray.trunk.2005091606.xpi Actual Results: Error about Extension versioning Expected Results: Extension installs I was able to get it to install by changing the value of app.extensions.version from 0.3a1 to 0.3. I don't think that the original value is valid syntax for this version so I'm filing a bug.
