Account Switcher doesn’t do anything due to a breaking change in Firefox 48.
This is fixed in RES v4.7.4, which can be installed via the beta channel.
Images from reddituploads.com and i.redd.it are not resizable and do not show when “view images” is turned on.
This is fixed in the next release of RES.
reddit now automatically opens the linked image when visiting a comments page. These expandos can’t be resized and don’t use RES’s keyboard navigation.
New Comment Count notifications (pop-up for “new comment made on post”) don’t show.

Sorry, neglected to fix this for 4.6.1.
