Title: Remove showPreviousViewOnLoad preference

After #4559, we no longer store the view history permanently in Firefox.
I think that keeping the preference `showPreviousViewOnLoad` around will be confusing, and unnecessary, for the user. Hence I propose that we can remove the preference, since the behaviour that setting `showPreviousViewOnLoad = true` gives is now the default in the main build target (i.e. Firefox).
