I wish there was a way to add expressions as straight-up regex entries. Wildcards are nice, but very limiting for those who know regex.
Other than that, it's a fantastic add-on!

Other Users are lying! It works great!

I was about to uninstall Firefox. But thanks to this addon I can finally delete search suggestions again! Firefox is unusable for me without this app

I love that not only can you delete history older than a number of days, but also by domain. I have not experienced any problems with this plugin.
Ability to whitelist domains would be a nice plus.

things disappear! wow

Good. I was looking for an option to remove history after X days in FF and couldn't find it. This add-on helped me fix this problem. Thanks

Great! I hope to see this on Android too soon!

Got it to do what I needed. UI could be improved.
