This has always been one of my favorite add-ons for Mozilla. If you're conscious of resource consumption and you need clearly delineated bookmark folders to organize your current research, intended projects, review materials, and so on, this is the only choice. If you don't mind your browser using as much memory as a 3d animator, the other one is slightly prettier by default.

Only 4, because custom CSS is not working on Firefox at all. Will there be any fixes?

希望增加批量选择，批量移动、批量删除功能。
增加刷新全部缩略图的功能。

This add-on was great for years, but in the last month it's suddenly started dropping my settings. I've tried reinstalling the addon and firefox and it just keeps happening.

How many times do I have to set everything up just to see it gone after restarting Firefox? Again, again and again. Works fine on Chrome, works like a nightmare on Firefox.

Годны дадатак , ужо даўно карыстаюся ім.

excellent app so easy to use and so handy

Exactly what I was looking for. Huge improvement over the default Firefox new tab.

Welcome page every time I open a new tab. Incredibly annoying. Welcome page opens with every new tab even after I continue through all the steps.

Было отличное дополнение на 5 звёзд, но после очередного обновления Firefox перестало работать - вместо вкладок пустой экран.

This has been a wonderful app to consolidate my bookmarks until recently, when it decided to change the layout I had set to a completely different one, with me having to change the settings like I have time to spare to do that, instead of going back to the way I have had it set up for the last several years.
