XKCDTooltip: Script working on mobile

[edgartaor]

I made a simple change to the script to work on mobile version of XKCD (m.xkcd.com)

// ==UserScript==
// @name           XKCD tooltip
// @namespace      https://github.com/Lorentz83
// @description    This script puts the xkcd tooltip under the picture and adds a link to explainxkcd.com
// @include        http*://xkcd.com/*
// @include        http*://www.xkcd.com/*
// @include        http*://what-if.xkcd.com/*
// @include        http*://www.what-if.xkcd.com/*
// @include        http*://store.xkcd.com/collections/everything/products/signed-prints
// @grant          none
// @version        1.6
// @icon           https://raw.githubusercontent.com/Lorentz83/userscripts/master/XKCDTooltip/icon.png

Hi, sorry for the very late reply, but I didn't notice the comment. What's the purpose of having it working on the mobile version? The comment is already visible and (to my knowledge) there is no way to run userscripts on mobile browsers.

[edgartaor]

Many people share XKCD links through their mobile phone (http://m.xkcd.com/) and when I click them I end up in the mobile version even if I'm on a desktop browser. And some times I miss the "EXPLAIN" button

[Lorentz83]

I see your point. If you want to create a push request I'm happy to merge it in the official repository. In this way you also keep the credit. But please, update the version number and add a small changelog in the readme file. Otherwise, this script is pretty stable now. I don't think I'm going to change it soon. You can keep your version in this comment as a sort of branch.
