You have wrote that original windows users problem is resolved. However, it remains unclear what is meant by this? Is it resolved by TB update or what?
The freezing problem still exists.
So what are the steps I need to take to resolve this issue?
Hi,
After updating to 71.0b1 (32-bit) on Windows 10 (Home), a similar problem started to manifest itself (it wasn’t present in the previous version).
The problem appears when trying to introduce an email address in the “To:” field when writing a new email or responding to one. The CPU usage jumps to about 25% (on a relatively old Core i3, not sure this is relevant) and the entire program freezes for 10 to 30 seconds, sometimes longer.
Perhaps it’s worth mentioning that there are about a dozen email accounts in use with literally hundreds, perhaps thousands of addresses in the address book.
Istvan, what is the total number of contacts in your address books?
Somewhere around 17k addresses.
Still, I don’t think this has anything to do with the size of the address book, considering that the issue didn’t appear until the last update.
Edit: Perhaps it’s also worth mentioning that when idle, the CPU usage of Thunderbird is at around 15-16%. When the issue appears, it jumps by at least 10%.
Don’t be fooled - “Past Performance is No Guarantee of Future Results”. In this case, 71 beta has major changes to address book, which can easily affect performance.
One issue is being examined in https://bugzilla.mozilla.org/show_bug.cgi?id=1597394
p.s. your issue isn’t related to Defender, so it should not be posted under this topic. Better to post your own new topic
I was trying to troubleshoot with safe mode on, switching off antivirus, upgrading to latest Thunderbird etc. Finally found something that’s really quite stable. I switched off hardware acceleration. I hope it works for you.
I have been plagued with ‘not responding’ issues for over a year. Tried everything. Removed plug-ins, Hardware acceleration off, reinstall, remove profile lock, Disable search, no aftermarket anti-virus programs, no entries in address book, rebuilt index still hangs all the time. Especially when I empty junk or open an inbox. Only way to get out is to shut down app and restart. Sometimes multiple times before it works.
I have a new Dell computer with i7 9th Gen and plenty of memory. Task Manager shows no issues while TB is hung.
I am ready to kick TB to the curb.
