Thunderbird is excruciatingly slow - in every operation (I feel it most when compositing, but even just making my way through menus is sloooow). It feels like low memory, but I have 18gB or more of free RAM in Windows 10, and nothing else is running slowly.

What could I do to speed it up, as I am seriously considering switching email client, but don't know of anything as good?

    Is there some ongoing operation, e.g. antimalware scan? Some scanners are incompatible with some email clients. Temporarily turn off AV suite, and , if problem goes away, try a different brand. – DrMoishe Pippik Aug 26 '20 at 17:14
  • Truning off Avast seemed to improve things slightly, but still not aceptable. Typing during compose and nothing seems to happen, then the text shows up after a delay .... (+1 though, for a good suggestion) – Mawg says reinstate Monica Aug 27 '20 at 5:49

    @MawgsaysreinstateMonica slowness while typing describes a known issue with early version 78. You will want to update to 78.2.2 or higher (current version is 78.3.1). Regarding Avast, it certainly can cause issues*. But you don't need to turn it off, you can exclude parts of Avast that are affecting Thunderbird. * wiki.mozilla.org/… – wsmwk Sep 26 '20 at 11:12
  • That seems to have done the trick. One week later and things seem better. If you post that as an answer, I will accept it. Thanks for your help – Mawg says reinstate Monica Oct 2 '20 at 7:55

Could be lots of things, including hardware. Suggest you review https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems and post your results

Open Task Manager (alt-ctrl-delete) and look at your processes. The culprit could be thunderbird or another program that is hogging all your disk usage, cpu, and/or RAM.

If that doesn't work, reinstall thunderbird.

  • Over 18gNB free RAM, CPU at ubder 50%, maybe 20% free disk space from 3tB. Reinstalling is a last resort, unless you can tell me how to save my config. Thanks for the advice, though :-) – Mawg says reinstate Monica Aug 27 '20 at 5:46
