ForceRs, hopefulli someone knows how to do this, but in the meantime a workaround might be to create a bookmark for "about:preferences", as this page too shows your current version, the latest version, and gives you the option to update if one is available. However you will need to manually scroll down to the Firefox Updates section, near the bottom, to see this. (or you could start typing the first few characters of "update" into the search box to bring that section up - the search box is already focused when the settings page opens, so you don't need to click on it first before typing. Or you can press alt+shift+P until the "Show Update History…" button of the update section appears.) BTW you could also set Firefox to automatically update, unless if you just prefer doing this manually of course.
