When this add-on works it's terrific. Since the advent of Thunderbird 38.0.0 in particular, however, it appears Google Calendar Tab is the source of the frequent "Not Responding" messages and delays I've been experiencing. If this annoyance can be remedied I'll happily boost my rating. Thanks in advance for checking into its performance and making the fix.
