Check this page with Do4U

One bookmark in your browser: click it on any website and Do4U opens in a new tab with the address of that page in the field. The default is Website check; further down you find bookmarks for other tools with an address field.

Check with Do4U

Set up in three steps

  1. Show your bookmarks bar (Ctrl+Shift+B, on a Mac Cmd+Shift+B).
  2. Drag the button above into the bookmarks bar.
  3. On any website, click the bookmark: Do4U opens in a new tab with the page address already in the field.

What the bookmark passes on

Only the address of the open page, without the part after #. No page content, no cookies, no form data. Do4U only puts the address into the field: nothing starts and no credits are used until you click the button yourself.

Other tools with an address field

Each of these bookmarks opens the tool in your account (after signing in) with the address filled in.

Without dragging (for example on a phone)

Create a new bookmark and paste this code as its address:
