Unless Nav is set to display the last page visited on startup, browser.history.last_page_visited shouldn't be set or writen to the prefs, for performance and privacy reasons. (user could clear cookies and cache, but the pref will still be around)
This belongs to history. I'm not sure whether it's session or global though. Guessing global...

Taking, I have a patch in the works for this. The perf issue really isn't that big here since we have to either read or set the pref in this case. However, we can get a perf win by not getting a new pref service for each page load. My patch will do that too.

Created attachment 93057 [details] [diff] [review] Patch v.1.0 Uses our new pref APIs and caches the prefbranch we use so as not to keep creating them for every page load. Fixes this bug by checking the pref in C++ and not setting anything if the user doesn't want to track their last visited page, and fixes JS code to do the right thing when we switch between prefs. Plus makes the buttons work as they should (Set to current page is disabled if the home page is the current page, same for set to default).
