breaks dark reader, boo white background-ed emails.

This review is for a previous version of the add-on (3.2.33). 

Hi, unfortunately the breakage with respect to dark reader is a combination of how the add-on works and some issues in Thunderbird. There is some significant work to fix this and we've been prioritising improving the maintainability of the add-on to keep the general add-on working. Hopefully we can look at this soon. The work is tracked here:

General dark mode support is also desired, again delayed due to prioritising other areas, and we are open to help if anyone wants to help with that:
