Alright, well, the problem has been narrowed further...

1. I made a 10GB volume on E: using VeraCrypt (an updated fork of TrueCrypt) and copied my 2GB Firefox profile to it. The profile loaded fast.

2. However, when I made a 10GB TrueCrypt volume on the same E: drive, that was also fast. So it's not a TrueCrypt only issue.

3. I then converted my big Z: drive from TrueCrypt to VeraCrypt, the Firefox profile was still just as slow loading as with TrueCrypt. So the problem appears to be a big volume that's encrypted with either TC/VC. I was hopeful of VC since they said there are fewer performance issues. I'll ask them about it, but if anyone has any suggestions, let me know here. Thanks!

Wait, What ? How do you wind up with a 2GB Profile ?

1. webappsstore.sqlite is 431 MB and storage/temporary is 700 MB

2. When I sync'd that profile to a new profile, it was much smaller but the same lag was there if the profile was located in the big encrypted Z: drive. On the other hand, when I had a small encrypted file, even the 2GB profile worked fast.

1. webappsstore.sqlite is 431 MB and storage/temporary is 700 MB

Both seem, to me, compared to what I have (12 / 27 MB), rather huge.

Note that some extensions store their settings/data within storage.
(uBlock, in storage/default. Oh, & my 27 MB is mainly from uBlock. The actual /temporary/ is 0.)

2. sync
I know nothing of sync, but maybe it skips much of or all of storage/temporary?

This could be a long shot, but make sure you don't have bitlocker turned on on the hard drive partition that stores the encrypted container file. If you did, it would be double-encrypting and it might rewrite large portions of the container every time a small change was made. It is also typical to exclude the container file from your antivirus software for a similar reason, to avoid repeated scanning of a huge file.

I don't have bitlocker, so that's not an issue. I've excluded the encrypted file from Avast, but unfortunately that hasn't changed anything. Thanks for the suggestion though!
