Version 128.10.2 here or through internal updater. No Betterbird version.
Q: Why is there no Betterbird 128.10.2?
A: The Thunderbird folks shipped 128.10.2 to fix the UNC path issue, see below. If you’re affected by this issue, please use the “latest [May 19th v128.10.1] build.” Let us know if you need a specific localisation.
