After a new install of Windows 10 on my new Dell, I installed MozillaThunderbird and it worked beautifully.

After two weeks of regular use, everything changed: first, it lost most of my emails. Now it takes a minute to invoke, and at least a minute between every mouse operation. It can take 15 minutes to download a few emails.

After research on this forum and many other relevant sites I took advice on possible viruses, interaction with anti-virus software and many other issues. I have repeatedly scanned with MWB, Panda. Bitdefender, Windows Defender and Kaspersky - including in Safe Mode. I have both used and disabled several reputable anti-virus programs. I have checked Task Manager looking for anything hogging resources and recognised nothing relevant. I have deleted and re-installed Thunderbird twice.

All other applications work well and fast.

I would be grateful for any advice - Thunderbird is a great product and I really wish to continue to use it.

Many thanks,

Philip

Thunderbird has worked perfectly since removing Cloudmark.

I understand that AVG have reported their product doesn't work with Thunderbird, so I'll not rely on that - even tho it notifies me that it Is scanning . . .

Grateful thanks to all contributors

Try to start Windows in safe mode with networking enabled. - Win10 http://windows.microsoft.com/en-us/windows-10/change-startup-settings-in-windows-10#v1h=tab01

Still in Windows safe mode, start Thunderbird in safe mode. - https://support.mozilla.org/en-US/kb/safe-mode

Does the problem go away?

Christ,

Thank you for taking the time to help me. I put Windows AND Thunderbird into Safe mode (didn't know there was a TB safe mode), with all apps and extensions disabled. Certainly after a couple of test Get Messages it seemed to work at normal speed.

I'll play with it a bit in Safe Mode and see if it behaves. Am I right in thinking this suggests one or other of my plug-ins or extensions might be interfering - or might a spell in Safe Mode make some other sort of repair?

For what it's worth, my list of extensions etc includes Bitdefender, Cloudmark (Spam filter), "Use Bcc instead"; Default 38.6.0 (whatever that is);Adobe Acrobat; Garmin Communicator; Google Update; Intel Identity Protection; iTunes Application;Microsoft Office 2016; QuickTime Plugin;VLC Web Plugin.

Most of these installed themselves without my asking (or knowledge) - but nevertheless for the first two weeks it worked perfectly with at least some of these.

It's past my bedtime now (Matron says I'm keeping the other old men awake), so I'll get back to you tomorrow. Many thanks

Dear Christ,

Thank you so much for your advice. I experimented with Thunderbird and it's various add-ons and extensions; I have proved (to my satisfaction) that the culprit is Cloudmark (a paid-for spam-filter which I'd used for years on Outlook successfully). I have removed this, and re-instated AVG - which doesn't interfere.

It's interesting that most of the web-based advice about Thunderbird poor performance is related to anti-virus stuff - which took up a huge amount of my time investigating. I'd not seen Cloudmark blamed before.

I think this is the first time in my (too long) life that I have incontravertable evidence of being helped by Christ: my faith is restored.

Many thanks,

Philip

Good you found the culprit (and your faith). Wrt AVG, even though it may work now, that doesn't necessarily mean it will always work in the future, and AVG may well be the problem then.

When your problem is fixed now, can you mark the thread as 'Solved' please? Thank you.
