Show comic title-text wót Peter Simonyi

Show the title-text below a comic page. Instead of having to hover the mouse to read it, the text is just there already. Actually, it doesn't have to be a comic — you can turn this on for any domain.

Firefox for Android is now supported, but due to missing WebExtensions APIs, the context menu is not available and extension preferences won't sync with Firefox Sync.

Usage:

Since many images have title-text, you have to set which image on which domains is a comic with interesting title-text. The easy way to add rules is with the context menu: right-click on a comic and pick "Set title-text rule with this image". Context menus are not available in Firefox for Android.

The extension can guess what rule should be added and offer a page action icon (in the location bar). This is disabled by default because it may slow down page loading (and the guessing will not be as good as just right-clicking on the comic), except on Android where it is the only convenient way to add rules.

You can edit (or manually create) rules in the add-on preferences. Each domain is associated with a CSS selector identifying the comic image. For example, #comic > img would work for xkcd.com.

Once you've finished adding most rules, you can remove the context menu entry or disable the page action from the add-on preferences.
