Two of them so far. Both run entirely in your browser, and neither asks for permission to read your browsing history.
Extension 01
ENV Portal
The same page, in every environment, one click away.
Open a page on production and get the same path on staging, on a branch deployment, on localhost and in Jira. ENV Portal reads the address of the tab you are on and rebuilds it for every environment you have configured. It never asks for permission to read your browsing history, because it does not need it.
A pause between you and the site you did not mean to open.
Blocking a site outright teaches you to turn the blocker off. Few Seconds Focus asks you to hold a button for a few seconds instead, which is long enough to notice you are doing it. Set your own rules per group of sites, with schedules for the hours that matter.
What you get
