Hi,
Looks like CentOS 7 hasn't shipped Thunderbird updates for a while. The latest I see in repos is:
Sep 1 15:22 thunderbird-91.13.0-1.el7.centos.x86_64.rpm
Perusing through the RHEL announcements, that was from the RHSA-2022:6169-01 on 2022-08-24. Seems none of the 102.x versions have shipped:
2022-09-26 RHSA-2022:6710-01 thunderbird-102.3.0-3.el7_9.x86_64.rpm
2022-10-18 RHSA-2022:6998-01 thunderbird-102.3.0-4.el7_9.x86_64.rpm
2022-10-25 RHSA-2022:7184-01 thunderbird-102.4.0-1.el7_9.x86_64.rpm
And for completeness, just announced today:
2022-11-21 RHSA-2022:8555-01 thunderbird-102.5.0-2.el7_9.x86_64.rpm
Thanks in advance for efforts to find and clear the blockage!
