Actual results: I have a problem with his extension that used to work fine but now is looking the computer (using Lubuntu 14.04). And I am not the only one as several users reported the problem in the module critics. I get the message (rough translation in English): A script on that page might be busy or does not respond any more. You may stop that script now or continue to check whether the script will end. Script : chrome://calendar/content/calendar-unifinder.js:898 And then Thunderbird hangs and I have to kill it.
There has been a major rewrite of the Provider for Google Calendar between version 0.32 and 1.0. A vast number of bugs have been fixed during this rewrite, therefore I am closing lots of old bugs that I think might either be fixed or no longer apply to the latest version. Please read the updated FAQ  for details on known issues. If you can reproduce your issue with the latest version of the Provider for Google Calendar and you can't find an existing bug that handles your case, please reopen this issue. Thank you for your understanding.  https://wiki.mozilla.org/Calendar:GDATA_Provider
