1) I upgraded HTML5 Videos Everywhere! 0.1.1 to 0.2.30 in IceCat 31.4.0. 2) I quited abrowser. 3) I I upgraded to IceCat version 31.5.0 (which I was not aware of). 4) I started IceCat (now 31.5.0)5) I can now "remove" HTML5 Videos Everywhere! 0.2.30 from the add-on list, but when I restart IceCat it appear again. Of course it should not be possible to "remove" it as its integrated in the latter version of IceCat.
Can you please have a look at this bug? -- http://gnuzilla.gnu.org
