QBF: Quick Bookmark Filer od Philip

QBF replaces Firefox's Ctrl+D → Edit Bookmark → Folder steps.

<b>The QBF window</b> — Ctrl+Shift+F (⌃⌘D on a Mac), or right-click the toolbar icon.
Save: file the page by searching your folders, or from your pinned folders or the whole tree.
Find: search bookmarks by name, folder or address, and open, move or rename them.
Tabs: every open tab in every window, with a mark on the ones already bookmarked.
History: pages you visited and tabs you closed, by day.

<b>Quick Save</b> — click the toolbar icon, or Alt+Shift+D (⌃⇧D on a Mac).
Type a few letters of a folder and press Enter. QBF opens on the folder you most likely want for that page.

Every action has a key, and you can change them in Firefox's extension shortcuts.
Tested with 100,000 bookmarks.
Every save, move, rename and delete is checked before it is written.
QBF collects no data and has no server of its own.

<b>Why it asks for</b>
Bookmarks and tabs: to save, find and move them.
Browsing history and recently closed tabs: for History.
Clipboard: when you bookmark an address you have copied, to fill it in.
All websites: to read the title of an address you bookmark that is not open in a tab.
Downloads, optional: to save backups of your bookmarks.
