Pin a note to a specific page and it appears only on that tab. Switch tabs and it hides. Reopen the page — even on your other Mac — and it comes back, right where it belongs.
A note about "the thing to fix on this page" floats on the desktop, detached from the Firefox tab it's actually about. Switch to another tab and it's just noise — a reminder with no idea which page it belongs to. The page and the note that goes with it are never tied together, so the note is in your way everywhere except where you need it.
A note sticks to the page's URL — which TackNote reads from Firefox's address bar via Accessibility — so it shows only when that page is open. Switch to another tab and it quietly hides; come back and it's there again. The note lives with the page, not on your desktop.
Closed the tab? Open TackBoard and click Reveal — TackNote reopens the exact URL and the note returns with it. The note is the shortcut back to the page it belongs to.
The same web note can appear on your other Mac — synced through your own iCloud, end-to-end encrypted — and even in another browser, matched by the page URL. One note, the right page, wherever you're working.
Firefox is a Full-tier integration. Firefox exposes no scriptable URL, so TackNote reads it from the address bar of your live focused window via macOS Accessibility — and since Firefox hides the scheme, TackNote restores the https:// for an exact match. From there it shows the note only on that tab and brings it back when you reopen the page. If a synced note's browser isn't installed on a given Mac, TackNote offers to open it in that Mac's default browser instead.
A note binds to the page's normalized URL — read from Firefox's address bar via Accessibility — so it appears only when that page is the active tab and hides everywhere else.
Click Reveal on a web note and TackNote reopens the exact URL it belongs to — the note returns with the page, even after you closed the tab.
Web-page notes sync through your own iCloud, end-to-end encrypted, and reappear on the matching page on your other Mac.
Matched by URL, the same note can show in another browser. If that browser isn't installed on a Mac, TackNote offers to open it in the default one.
"I reopen the page in Firefox and the note is already there — waiting on the exact tab — on whichever Mac I sit down at."
Yes — by the page's URL. A note shows only when that page is open in Firefox and hides on every other tab.
Firefox exposes no scriptable URL, so TackNote reads it from Firefox's address bar via Accessibility, watching your live focused window. Firefox hides the scheme, so TackNote restores the https:// for an exact match. No extension required.
Yes. Web-page notes sync through your own iCloud, end-to-end encrypted, so the note returns on the matching page on your other Mac.
The same note can appear by matching the page URL. If the original browser isn't installed there, TackNote offers to open it in your default browser.
No — TackNote is a separate menu-bar app. It reads the address bar of your focused Firefox window, nothing more. There's no browser extension running inside Firefox.
