Very useful extension for organizing bookmarks. It has few glitches so it's recommended to comb through found results and doublecheck them and not just automatically fix them in bulk, but still, at least it points out things that might be obsolete or not resolving to the same address as it was initially bookmarked. Still easier checking few 10 potentially problematic bookmark entries than manually combing through entire bookmark database which can be in hundreds or even thousands of entries.

Does what it says, very helpful!

Maybe a name like Bookmark Cleaner or Optimizer would be better but I'm glad this exits.

長年のうちに溜まってしまった大量のブックマークの整理ができて助かっています。PCスペックや回線にもよると思いますが、ブックマークをチェック中に他の作業をしていても特に影響を感じません。

Excellent addition to my Firefox addon arsenal!
