Silvermel current version (v2.0.1) isn't compatible with Thunderbird 52.* You can edit the extension to use it in v52 and looks like Silvermel works fine. Instructions: http://forums.mozillazine.org/viewtopic.php?f=48&t=1520265&sid=31621ec02c683ac9d464d5b1e9f26774&start=1755
A brilliant theme which for years was hugely popular and completely outclassed the default theme. You only have to look at the forums to see how popular this theme was and how much people want to update it. Sadly the developer no longer has time, therefore in the interests of the open source community this should be made open source so others can work on it. I doubt many people will be buying him a beer if he's too busy. One star as it's no longer compatible with current versions
