During the past 20 days of using Pale Moon, I have found that the latest version available can be installed with compatibility check disabled, but glitches are obvious. The version with least problems may be 1.5.7, but the RSS feed icon in the location bar is still absent.
Fortunately today I have found Pale Moon - Add-ons - Theme Compatibility Provider. With it, Charamel 1.5.7 is close to perfect on Pale Moon.
I'll try Charamel 1.6.1 and 2.x.x again and report here.
- 2.0.1 on AMO does not look good
- 1.6.1 looks fine now with Theme Compatibility Provider
