Hello Thomas, and thanks for your complements. I am happy to hear that you enjoyed using my theme with Firefox, and that you are still enjoying it with the Pale Moon browser.
While I have been aware of the Pale Moon browser since it came out, I have not chosen to download it.
I am presently still using Firefox and will continue to do so unless the Mozilla people take things too far in a "radical direction" for my taste. If that does happen, then I will give Pale Moon a look.
Unfortunately I am not in a position, at this time, to work on FOXSCAPE for any browser (Firefox, Pale Moon, SeaMonkey, etc.).
The issue with Pale Moon browser and the RSS feed icon causing a glitch probably would be easy to fix by someone who is familiar with themeing in Pale Moon. I suggest asking someone in a forum, if one exists, for Pale Moon theme development and ask if they can help to fix the bug.
I am sorry I can not be of more assistance in this matter, but I hope you can find someone as I suggested above.
Thanks for pointing out Pale Moon, and for your support.
