Sometimes it's hard to find resources in the Canvas Community and often awesome things are overlooked due to the sheer volume of information. To make it easier for people, the following is a comprehensive list of Canvancements (Canvas Enhancements) James Jones has developed for Canvas. James would never sing his own praises, but I have no problem doing so on his behalf. Enjoy!

November 21, 2017: Greasemonkey 4 / Firefox 57 note

It appears that there is a bug with Firefox 57 that is keeping Greasemonkey 4 from working. It basically keeps any script from Github from installing, updating, or running and you can't create local scripts either. Github is where all of the source code for the Canvancements are stored. There is a way to temporarily disable a security protocol in Firefox that is provided in the bug report, but my recommendation at this point is to use Chrome or Safari or to install Tampermonkey for Firefox. Firefox will not be fixing this issue in Firefox 57 as it's not a security bug, Greasemonkey 3 no longer works after upgrading to Firefox 57, and it would completely change the way Greasemonkey injects and detects user scripts to fix (meaning I don't expect them to fix it).

 

Further investigation shows that existing Greasemonkey scripts may try to execute as I'm getting error messages that don't appear when Greasemonkey is disabled. Since they are loaded as content scripts, they get access to a cleaned version of the DOM and cannot see external JavaScript libraries like jQuery or variables like ENV or INST that Canvas provides as a page script. Early paranoia suggests that Greasemonkey may not be a viable solution once you upgrade to Firefox 57+. Although I've been moving towards avoiding jQuery (for no real reason at the time, but now I'm glad I did), I still use it when making AJAX calls to fetch data from Canvas.
