A mouse gestures extension for Firefox. This project was started as a web extensions alternative to FireGestures. Unfortunately, FireGestures will stop working when XUL/XPCOM add-ons are fully deprecated in Firefox 57.
FireGestures is a very mature plugin with a huge number of features. Although I used it for many years, I probably didn't use it in the exact same way as you. Some features maybe have been unintentionally ignored or forgotten by me. I am slowly implementing features in Foxy Gestures as my time allows. This wiki article contains a list of supported commands vs FireGestures. The list is not exhaustive and you can request features using GitHub issues even if they are not currently planned.
As a web extension, this add-on will never be as powerful as FireGestures. This extension does not integrate into about:home, view-source:, etc. Nor will it work on addons.mozilla.com, since web extensions are forbidden from interacting with the add-on store.
More importantly, the mouse gestures will not work until the document body of the website you are visiting has parsed. In other words, the DOM must be parsed but content does not have to be loaded. This limitation also applies to frames within the website. This is an inherent limitation of web extensions at the moment, because there is no API to get mouse events from browser chrome.
In OSX and Linux, the context menu is shown on mouse down. (Context menu on mouse up is the default for Windows.) When FireGestures is installed on OSX/Linux, it changes the context menu to be shown on mouse up. Web extensions cannot replicate this functionality. Due to the issue described in #4 right-button gestures work poorly in OSX/Linux.
An option to use a modifier key to start or ignore gestures is being developed. If you want to see a proper solution to this issue, please support this Bugzilla entry. Update: the bug was accepted and is awaiting a user contributed patch. If you are available to help write this patch please contact me.
This extension hooks into DOM mouse events. However, each frame in a website is a separate DOM often with a separate origin. In a naïve implementation the mouse gesture would stop tracking whenever the mouse passed over an iframe.
The solution is to have the web extension inject mouseEvents.js into every
frame. Each time the script loads it will determine if it has been framed. If
the script has been framed, it will establish communication with its parent
frame (also running mouseEvents.js) via postMessage()
. Nested instances of
the script will relay mouse events up the hierarchy. As the message bubbles up
the hierarchy, each script applies a coordinate offset based on the position of
the nested <frame> or <iframe> element. In this way, the top-most
script sees all mouse events in the coordinate space of the top-most DOM.
mouseEvents.js also maintains a small amount of state. To keep all instances
of the script in sync, this state is replicated by passing messages down the
hierarchy. Ultimately, this setup provides the extension with a seamless view
of mouse events across all frames upon which to build the rest of the extension.
It is worth noting that DOM references cannot be shared via post message. As a result, a reference to the element under the mouse gesture is only available in mouseEvents.js in the frame which generated the event. To support features that need information about the element, attributes are collected a priori and bundled with mouse event data for mouse up/down events. To support situations that require access to the live DOM, mouseEvents.js assigns a unique identifier to each frame in which it loads. Messages may be addressed to a specific frame using the unique frame ID.
