Thank you for the feedback.

TLDR; For users that are happy with the built in Reader Mode, there is no need to use this extension.

This extension was first created in 2012 when there was no built in Reader Mode in Firefox.

Once Reader Mode was introduced in Firefox, for a while the listing description of this extension encouraged readers to first try the builtin Reader Mode and use this extension only if/when the user is not satisfied with Reader Mode.

Reader Mode works on on web pages that have an "article" tag (to the best of my knowledge) -- it is not enabled on pages that don't have an article tag. This extension works on pages even without an article tag.

There are always some pages where this extension does a better job that Reader Mode; and the converse also holds true.

Here are some of the additional features that are available that some users like:

(1) Finer ability to customize fonts, font size, reading width, background color etc.

(2) Ability to save pages locally for offline reading (and to add annotations/notes to offline articles); export/import such pages (as opposed to using an online service like Pocket)

(3) "Continuous browsing mode" -- when in the transformed view, clicking on a link will automatically take you to the transformed version of the page referred to in the link

Refer to the extension listing for more features.

Thank you for pointing out this problem! I forgot about the icon displayed in the context menu.

I looked into the documentation and the icon is being picked up from a default icon value that is specified in a manifest file (packaged along with the extension).

However, I am unable to find any programming API that allows me to change the context menu icon (the documentation indicates that only icons for the sub-menus of the main context menu entry can have customizable icons). I will continue to look into this, in case I've missed something.
