Stylish addon, installed by default, is incompatible with the current version of Firefox

[Mar-castelluccio]

This addon is incompatible with the current version of Firefox. If it's unused by Mint, it could be removed.

There is an updated version available on addons.mozilla.org, should definitely be updated or removed.

This is absolutely 'critical' to fix IMO.

The obsolete version of Stylish still installed by LM prevents many (most?) styles on userstyles.org from being installed!

For example, the style at
https://userstyles.org/styles/5546/bookmarks-toolbar-selectively-iconize
makes Firefox usable for me as I have many bookmark folder icons that must be supressed.

It is Not a Minor issue!

Apparently Stylish is installed during LM installation by the package mint-stylish-addon which claims to fix other issues.

In view of the major changes to firefox with version 29 (Australis look) the functionality of this package needs to be reexamined as soon as possible.
