Changes
some additional changes relevant for TB 60
* Assignment to .innerHTML of an element does not work any more in chrome documents. As a temporary workaround, .setUnsafeInnerHTML or |document.allowUnsafeHTML = true;| can be used. This workaround was removed at mozilla61. The correct solution is to use .textContent, document.createElement(), DOMParser.parseFromString or document.execCommand("insertHTML", ...). Note that the jQuery library uses .innerHTML.
* Expression Closures have been dropped: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Expression_closures (use arrow functions).
== Other changes relevant for TB60 ==
* TB does no longer automatically pick up code changes if the addon is in a directory. Code changes are only picked up if install.rdf is changed. Also, it appears that TB needs to be restarted twice for the new code to come over (e.g. by restart addon or manually).
* Certain ways of defining Cu, Ci etc. do not work any longer, because Cc, Ci, Cu, and Cr are now defined by default in chrome (e.g. this does not work: const {classes: Cc, interfaces: Ci, utils: Cu, results : Cr} = Components; as found in some addons)
