Thunderbird crashing after W10 April update

Hello everyone. I have been getting recurring and seemingly random crashes since I update Windows 10 to the latest version, 1803.

I have tried running Thunderbird in recovery mode and it doesn't crash. Trouble is, I disabled every single plugin and extension and still I get the crashes if I run in normal mode.

So there must be some difference between normal and recovery mode which starts the crashes, but I have no idea what it may be.

The installed version is the latest version. I tried with an older version, 44-something, and still there are crashes.

Chosen solution

The problem got solved after I moved prefs.js, started TB, closed it and moved the file back.

No idea why, probably some old setting causing havoc. Hardware acceleration is on, but the problem is no more.

I was getting crashes whenever moving mail between folders, narrowed it down to Windows Search Indexing of the downloads folder (or all things). Turning off Search Indexing within Thunderbird settings doesn't seem to override the Windows 10 indexing.

So you disabled the option in Thunderbird and your crashing stopped?

Please post your crash IDs.

zoll, cooperdoop,

Perhaps you have IDProtect installed?
