Couldn't load XPCOM

[Phil Williams]

I would like to bring this to your attention.

I got the error "Couldn't load XPCOM" after Seamonkey updated to 2.53.17.

I run a Windows 11 machine with the following spec:
Device name    Spinner
Processor    Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz   1.99 GHz
Installed RAM    8.00 GB
Device ID    AD6032F5-1552-483B-BEEE-55CF00E22D84
Product ID    00325-96241-13341-AAOEM
System type    64-bit operating system, x64-based processor
Pen and touch    Pen and touch support with 10 touch points
Edition    Windows 11 Home
Version    22H2
Installed on    ‎29/‎09/‎2022
OS build    22621.1992
Experience    Windows Feature Experience Pack 1000.22644.1000.0

I initially used a restore point to get myself up and running as I didn't know what the cause was. I followed by updating Seamonkey from 2.53.16 to 2.53.17 and the error came back.
I eventually downgraded to 2.53.16 and all appears to be well. I have now disabled automatic updates.

I guess there is some incompatibility with my machine and v. 2.53.17 so I will see what 2.53.18 brings.

Seamonkey is fantastic and I can't be without it. Thank you for a great piece of software.

Kind regards,
Phil Williams.
