TB 152 - QF Version 6.16.3 - freeze on first start

[GitRonimo]

Since a couple of QF versions or TB Update I experience reproduceable freezes on selecting first mail on the first start of the day of TB - "Keine Rückmeldung" for about 30-60 seconds.
Win 10 - as long as possible :-)

Can you try the latest build here:

QuickFolders-mx-6.17pre62.zip

---

To install the version above, download the zip file and then drag the file into Thunderbird Add-ons Manager. Do not extract contents, it will not install that way. This one includes changes to issue #677 which converts storage from legacy to browser storage.

Hey, thanks. I did install it, will let you know tomorrow morning

Good Morning, Sorry Axel, the AddOn wasn´t active this morning upon start, so I need another 24 h before I can give you feedback. Best Regards, SJW Am 09.07.2026 um 17:31 schrieb S.-J. Wilm:

I can confirm now that this version did help - but not eliminate the freeze upon start.
Instead of immediatly freezing I could handle some mails, than it froze but only for 2-3 seconds, Definetivly an improvement.

I added code to the 3pane file (which is in charge of the Current Folder toolbar injected in center screen). Might even improve performance for all 3pane tabs and single message tabs.

Good Morning, I can confirm now that I have no issues anymore, No freezes. Thank you again.

Sadly the freeze happened again this mornings first start. But it was not instantanious on TB start, I could handle some mails and then it froze for 10 seconds.

Could it be caused by filters running on incoming email? If you have filters that check body or deal with attachments then this could explain it - if you use FiltaQuilla enable its debug mode. Try to open the browser console (Ctrl+Shift+J) with timestamps enabled straight on startup to see whether you get any errors, warnings or excessive logging:

getting the console up in time may be tricky but it will show you the log from the start even if you open it after the delay.
