Autocomplete drastically slower in Thunderbird 64b4 vs 60

Thunderbird Beta
#1

I have around 10,000 contacts in my Thunderbird address book, which I admit is a lot.

However, in Thunderbird 60 the autocomplete on the compose window was still very fast.

Now it hangs for 2 to 3 seconds searching for options.

Is this a regression? In a much earlier version of Thunderbird (circa v.5 IIRC) there was a similar issue created by an ‘optimization’ to the way the filter worked.

Yes, there is a recent recgression. Fixed in version 60.4.0. And patch for beta 65 landed https://bugzilla.mozilla.org/show_bug.cgi?id=1511885#c30 but 65 is not quite released - until then you can find it at https://archive.mozilla.org/pub/thunderbird/candidates/65.0b1-candidates/build5/win32/

So you should find that beta 65 is better.

@jonathan_cutting version 65 solved it for you?
