Rated 5 out of 5 stars
This add-on is certainly an improvement over Self-Destructing Cookies in most ways; the fact I can import and export the lists is lovely (and not being able to do so was one of my peeves with SDC).
The only thing missing? A version for Firefox Mobile ;)
SDC Mobile has too many options stuck in the hamburger menu (three -- suspend, undo and whitelist), which clutters things - especially if you have *other* addons that add menu entries there (more addons should use the toolbar icons or at least give the option). It also lacks the option to manually edit the whitelist (which is *very* annoying on fresh installs), and shares the flaw from the original in that you can't import or export your settings.
Hopefully you'll take this into consideration; but it deserves 5 stars anyway.
