WordPress Login Bookmarklet
If you work on WordPress sites a lot, you’ll find yourself not logged in sitting on the about page with the request “Change the copy from this to that”, now you have to go back out to wordpresssite.com/wp-admin, then login, then go back to the page and click “Edit” in the control bar, OR log in through WordPress and choose the page from the pages menu.
This bookmarklet gets the domain of the site you’re on and automatically appends the correct url string to login and redirect you back to the current page.
Drag the link below to your toolbar and try it out on your WordPress site
