Install and pin

1. Install

Latr installs from the Chrome Web Store and works in every Chromium browser — Chrome, Edge, Brave, Vivaldi, Arc and Opera all install from the same listing. On Firefox it installs from Firefox Add-ons.

Get Latr, then confirm the permission prompt. It asks for very little, and what each permission is for is listed on the privacy page.

2. Pin the icon

Chrome hides new extensions behind the puzzle-piece icon by default. Pin Latr or you will forget it exists:

1. Click the puzzle-piece icon to the right of the address bar.
2. Find Latr in the list.
3. Click the pin beside it.

The icon now sits in the toolbar permanently. It doubles as the reminder counter — the badge on it shows how many reminders are pending, so a glance tells you whether anything is waiting.

3. Check notifications work

This is the step that matters. Latr can be working perfectly and you will still see nothing if your operating system is set to suppress notifications — and the symptom looks identical to a broken extension.

The fastest check:

1. Open any page.
2. Click the Latr icon, then Remind me about this page.
3. Type in 2 minutes in the When field.
4. Save it, leave the browser open, and wait.

If a notification appears, everything works. If it does not, go to if notifications never appear — it has the exact settings for Windows and macOS, and takes about a minute.

Optional: the keyboard shortcut

Latr suggests Alt+Shift+Y to save the current tab at your default time — an hour from now until you change it, under Settings → New reminder defaults — without opening anything. Chrome sometimes leaves a suggested shortcut unassigned if another extension already claimed it.

Check or change it at chrome://extensions/shortcuts. Latr always shows the key you actually have bound rather than the one it suggested, so the tips in the popup stay accurate if you rebind it.

That is setup complete. Next: save your first real reminder.
