Laser Pointer — Keivan Mirzaei

Use a laser pointer on any webpage. Move to point, drag to draw, and let your marks fade. Made for presenting, teaching, screen sharing and walking someone through a page.

How it works
- Click the Laser Pointer button and choose "Use on this website". Firefox asks once for access to that site.
- Move to point; drag to draw. Marks stay with the page as you scroll and fade a few seconds after you stop writing.
- Press Space to pause and use the page normally; press Space again to resume. Press Escape to turn the laser off.
- On websites you've allowed, the toolbar button turns the laser on and off directly.

Settings
Click the gear to choose one of three colours and three thicknesses, adjust smoothing, and keep marks visible for 1 to 20 seconds. Drag the gear anywhere on the screen.

Private by design
No ads, analytics, accounts or servers. Access is requested one website at a time, only when you ask. Laser Pointer doesn't read page text or form entries, and nothing is sent anywhere. Settings stay on your device; marks disappear when they fade.

Tip: pin Laser Pointer from the Extensions (puzzle-piece) menu so it's always one click away.

Firefox's own pages, addons.mozilla.org and the built-in PDF viewer don't allow extensions, so the laser isn't available there.
