Solution 1. Use Tampermonkey. Tampermonkey is more popular as an extension for Chrome, but it is also available as a standalone Android app. It functions as a lightweight browser, and allows you to manage and automatically run user scripts. Unfortunately it doesn't have many of the features found on other popular browsers, but it does support the ...
Use OilCan - "Greasemonkey on steroids for Android".
Directly on the device? I don't think so. If you have a computer running chrome, and a usb cord for your phone, then you can use Chrome's remote debugger to access a web console on your computer that can inspect pages open in chrome, and any in-app webviews that have debugging enabled. Basically, you just enable the developer options and remote debugging on ...
You'll have to copy and paste. I don't know why the long click doesn't work, but I assume because the url doesn't start with "http". I've found the easiest way to create bookmarklets is to do it on the PC and then import the bookmarks, or by copying the text of the js url to a text file, emailing or dropboxing it to my phone and then copying & ...
There is a Greasemonkey-like add-on for Dolphin called Tampermonkey. There is also a stand-alone Tampermonkey app, but Dolphin is a more full-fledged browser than that thing. There is also a similar add-on for Firefox for Android, called USI.
Use either the Habit Browser or Slepnir Browser apps. They both support Userscripts. I had to tweak my scripts slightly to get them working (they handle events differently) but they both work really well.

I couldn't find any good demoes of this, only proposals: https://github.com/clelland/BackgroundSync/blob/master/explainer.md Cordova has ...
This can be turned on/off in Chrome using flags. This is on the user end though and cannot be change in the browser from a website or app. You can also do this in your own app using the api for webview or websettings and make "getMediaPlaybackRequiresUserGesture(false)" it is by default set to "(true)" ...
Bad news it seems. Bug report on Google code The most relevant post is this: Yes. It is as design. "autoplay" is disabled for Chrome for Android It seems that Android 4+ changed the requirements for the play() method to require user interaction. Article on this issue It's worth nothing that many comments refer to getting it to work with a ...
As I mentioned in the comments the Twitter app doesn't seen to have an in-app browser so I'm using the Reddit Is Fun app instead since I know it does. I think that all in-app browsing uses a WebView so it should be the same across all apps. The WebView and Chrome both use the WebKit engine but Chrome seems to use a more up-to-date one. I tried out SunSpider ...
