Quote:1. It broke Lightning again, so i had to install the new Lightning version myself. Not difficult, but not a smooth experience having to manually intervene, rather than the repo taking care of it as part of the update.Lightning is part of thunderbird now. So I would recommend removing the addon installed manually and using our package xul-ext-lightning. This assures no breakage as this package is built everytime we build a new thunderbird package.

Quote:2. The previous TB correctly respected my Plasma desktop theming/colours, when "Default" Appearance was set. The new TB now ignores my personal settings, & just uses the drab standard boring GTK grey colours.Upstream changed theme handling again (in sync with the firefox 52 theme changes). Though in my tests I did not see any completely different/broken theme using the default theme we provide.
