Web Time Tracker от Web Time Tracker

Web Time Tracker is a Firefox extension that helps you understand your real browsing habits by measuring how much active time you spend on websites. It tracks per-site usage, total browser time, and visit counts, then displays everything in a clean popup with search, sorting, percentage bars, and visual charts.

The extension includes practical analytics tools: quick time filters (today, last 7 days, last 30 days, all time), daily and weekly chart overviews with tooltips, top-site summaries, and average daily usage. You can also customize tracking behavior with blacklist rules, optional subdomain merge, hidden sites, tags (for example work/personal/distract), and usage limits with subtle local notifications.

Your data stays local in Firefox storage. No account is required, no remote analytics are used, and no browsing statistics are sent to external servers by default. You can export your data to JSON, import it back later (merge or replace), and reset safely with automatic backup export before clearing data.
