Rated 4 out of 5 stars

This should be used to manage history in Firefox. It really really cuts through soo much content in a snap. Simple. Amazing. Can the interface become geared towards maniplulating places? Its so good it should be integrated! Every browser (not just FF) should get this. Great Job!

This review is for a previous version of the add-on ( 

Thanks a lot for the compliments. The reason I try this idea out in Firefox in the first place is that it's just a great open and extensible platform with detailed document and strong support from the development community. The implementation of the idea is quite straightforward, so if another browser use similar way to keep browsing history it shouldn't be hard to add such feature.

That being said, one major shortcoming of this plugin is the performance. As a former review mentioned, it takes quite some time to build the tree history. I myself have experienced "unresponsive script" warning during the searching, even though my browsing history is no more than 2 years old. One possibility in the plan is incremental searching, get 10 top nodes at a time for example.

Now I'm trying hard to interpret your suggestion as I assume it's part of the reason you took one star off. So far I come up with following possible aspects. I'd really appreciate it if you could clarify it a little through "Feature Request" or "Bug tracker" on the project's sourceforge page.
1) if it's about the search results: a) customizable display, like reverse order by date; b) more convenient ways to store and share the tree history (online); c) changing or deleting the history from FF browsing history manually (I feel reluctant to directly write or modify the FF database from the start, and I'm not sure if it's possible/recommended to delete records from the database. Even if it can be done, I can't think of a good reason so far).
2) if it's about link suggestion: a) make recommendation customizable, for example, specify words that you want or don't want in the suggested link, or specify some link that you'd rather not suggest ever again, etc; b) more friendly ways to access the link.

Again thanks for your encouragement and support.
