DistractBlocker от Muhammad Jahangeer

DistractBlocker connects to the DistractBlocker desktop app on your PC
to block distracting websites directly inside Firefox — no need to
keep switching between apps.

Features:
- Instantly blocks any site added to your Block Profiles
- Add the current page to a Block Profile in one click, right from
the toolbar popup
- Shows how many sites are currently being blocked
- Works together with Strict Mode, Timer Locks, and Frozen Locks set
in the desktop app
- Keyword-based blocking on any page you visit

Requires the DistractBlocker desktop app to be installed and running
on the same computer — this extension is the browser-side companion,
not a standalone product.

DistractBlocker does not collect, sell, or transmit any of your
browsing data anywhere. Everything stays on your own computer — see
the Privacy Policy for details.
