I'm running the betterbird mail handler on my linux system.
It quit working with the last update. Nov 2025
Error running betterbird version 140.4.0esr-bb13 (11 October 2025)
XPCOMGlueLoad error for file /home/spg/Downloads/betterbird/libxul.so:
/home/spg/Downloads/betterbird/libxul.so: undefined symbol: wl_display_set_max_buffer_size
Couldn't load XPCOM.
Solution
downgrade to version 128.14.0esr-bb32 (16 August 2025) to get up and running again
