Compatibility with Thunderbird 115

[garv-shah]

Hi there, I just found this theme and it looks amazing, but I am unable to install it on the latest version of Thunderbird!
Would there be any prospects of updating the theme? Thanks!

also not compatible with 140 which is a shame because this looks amazing!

September 2026, not compatible with Thunderbird 155.0. I am new to thunderbird, but am retired SW engineer. Could I get instructions on how to attempt to load into 155.0, and investigate what is needed?
