Tumblr Likes Calendar por Amicolinux

Tumblr's "likes" can't be searched or filtered, so finding an image you saved months ago means scrolling endlessly. Tumblr Likes Calendar turns your likes into something you can actually navigate by date.

On your Tumblr likes page it adds a GitHub-style heatmap calendar, one panel per year: each day is shaded based on how many posts you liked that day. Click any day to jump straight to the likes from that date.

Features
• Heatmap calendar of your likes, one grid per year
• Click a day to open your likes from that exact date
• Per-day like count on hover
• Fast: your data is cached locally after the first scan

Privacy
Everything stays on your computer. The extension reads your likes through Tumblr's own in-page helper (no API key needed) and stores only a local summary in your browser. No data is ever sent anywhere.

Note: the calendar shows when you liked a post, not when it was published. The number of retrievable likes may be slightly lower than Tumblr's counter, because likes on deleted posts or blogs are no longer returned by Tumblr (and are no longer reachable anyway).

Requires Firefox 128 or later.
