With FF 43 & Stylish 1.4 Rated 4 out of 5 stars
With FF 43 & Stylish 1.4, editor lost codemirror abilities and becomes just a plain text editor. But idea & features are great.This review is for a previous version of the add-on (0.8.4). This user has a previous review of this add-on.
this isn't tested/supported on Stylish v1.4, only v2.0.6 and up
uncompatable with stylish-editor-modified on old ff version such as ff35 Rated 5 out of 5 stars

Yes, I'll fix it
Edit: I should have replied sooner, but I cannot reproduce your issue.
All three buttons work fine on Firefox v35 with Stylish-Custom v0.8.4 and Stylish v2.0.6.
"preview/ install/edit/cancle" probably means you aren't using the correct version of something.
Edit2: Ohhh I've never tested SC with SEM, doubt they would work together well, and you probably shouldn't use them together. Of course it's up to you.
