xkcd Enhancer is a free small extension to view xkcd comics. It lets you personalise the comic viewing experience and add some features that you can't do with the official xkcd app.

There are 4 main categories to choose from and you can add more than 400 xkcd comics to your personalised collection. The categories are:

Themes – xkcd comics with a specific theme.

Favourites – Add a comic to your favourites list so you can view it easily.

Settings – Configure the settings for each comic.

Keyboard shortcuts – Set the keyboard shortcuts to go to next and previous page and to go to the next and previous comic.

Arrow key shortcuts – These shortcuts work like a normal link and when you click on them, they take you to the next or previous page.

Easy title text – Add the link to the xkcd comic in the title, so you can find it easily.
