ブックマークを追加すると、追加したサイトが別ウインドウで開いてしまいます。仕様でしょうか？

Please - add ability to change F2 hotkey to user defined hotkey. Developing in cloud IDE need that hotkey for their options.

The exact solution for the most niche problem I've ever had at work. I only wish I could pin certain bookmarks to the bottom the way the new tab shortcuts are laid out, it'd be perfect!

So useful

how about bookmarks and HISTORY too.

It would be great add-on if i could use history sidebar instead bookmarks. Add this option please. Thank you.

There are some Firefox limitations that prevent this add-on from functioning fully, but with what is available it is a lovely experience.
