Overview
Auto-closes the landing-page tabs that desktop apps leave behind after their deep links fire. Matches on domain + page text.
Oscar auto-closes the landing-page tabs that desktop apps leave behind after firing their deep-link handlers. It matches rules based on the page URL and the rendered page text, displays a live countdown toast with a Cancel button, and then closes the matched tab. When you click a deep-link message, your browser opens a tab that hands off to the desktop app's URL protocol, and then just sits there. Multiply that by a dozen meetings a day and your tab bar is a landfill. Oscar watches for those landing pages and closes them for you, with a live countdown and a Cancel button so you're always in control. FEATURES - Domain + page-text matching — closes a tab only when both the URL and the rendered page text match a rule, so you can't accidentally wipe a real Slack conversation. - Rule library — one-click presets for common desktop-app deep links, plus the ability to write your own rules by hand. - Live countdown toast — injected into the page so you see what's happening even if the toolbar icon isn't pinned. - Cancel button — change your mind mid-countdown and the tab stays open. - Usage analytics — lifetime counts, time-of-day patterns, top domains, cancel rate, streaks. All stored on-device, nothing ever leaves your browser. - Four themes — System, Light, Dark, and Garbage. PRIVACY Oscar is completely local. No accounts, no servers. The only external HTTP request Oscar ever makes is to Google's public favicon service, and only for the favicons shown next to rules in the options page.

It matches rules based on the page URL and the rendered page text, displays a live countdown toast with a Cancel button, and then closes the matched tab.
