derp help

Bring your passwords, bookmarks, history and cookies across — and, from Vivaldi, your workspaces and the tabs inside them.

Press F2 and start typing to run almost anything without hunting through menus.

The address bar can be hidden entirely; double-clicking a tab is how you navigate instead.

Two levels of tabs: a stack is one chip in the tab strip, and its tabs appear in a second bar underneath.

Separate sets of tabs you switch between, each remembering its own tabs.

Two or more pages side by side inside a single tab.

The page new tabs open on: your sites, a clock, a search box and a wallpaper.

derp's own settings, separate from Firefox's preferences.

Blanks the parts of the window that would give away more than you meant to share.

Retracts the toolbars and the status bar so only the page is left.

A sidebar for web panels, notes and extensions, kept beside the page rather than over it.

Hold the right mouse button and draw to run a command.

The shortcuts derp adds on top of Firefox's, and how to change them.

Keeps sites in separate compartments so their cookies and logins cannot see each other.

A notepad that lives in the sidebar, so it is beside the page rather than in another window.

Separate browsers on one machine, each with its own tabs, extensions and history.

Turns the page you are on into a QR code to pick up on a phone.

Where the tabs go and how much room they take.

Light, dark and the compact look derp ships with.

Installs a site as a standalone desktop application.

derp runs Manifest V2 extensions, so the full uBlock Origin works rather than the reduced Lite version.
