Quick note: Sidebrief relies on the native Sidebar API, a real docked side panel (not a popup). It works in Chrome/Chromium and Firefox. While Orion supports many extensions, it does not expose a sidebar API yet, so while you can install it... it won't work. Jumpbar works everywhere though!

Jumpbar for Kagi - Quick Actions for Kagi.com Jumpbar adds buttons to the Kagi.com homepage so you can quickly access Kagi features like Assistant, News, Translate, Summarize, and Small Web.

Jumpbar was made to put Kagi’s most powerful tools one click away instead of opening the control center every time. So, less digging to get to Assistant, News, Translate, Summarize, or Small Web.

I’ve been building two new extensions that work with @kagi.com.

Jumpbar adds quick actions to the Kagi homepage, so your favorite tools aren’t an extra click away in the control center.

Sidebrief brings Universal Summarizer to your browser’s native sidebar. Zero tab switching.

TabCloser - Close Leftover Tabs Automatically TabCloser frees you from clutter by automatically closing leftover tabs from services like Zoom, Figma, Slack, and more. Available for Chrome, Firefox, Safari, and Edge.

TabCloser v4.2.0 is out!

Fixes Slack /admin/* pages (settings, billing, etc.) so that they’ll no longer close.

Improves pending tab closures, which should now properly cancel if a tab redirects/navigates away

I’ve been expanding where TinyExtensions are available. You can install them from the Chrome Web Store, Microsoft Edge Add-ons, Firefox Add-ons, and the macOS App Store (or manually via GitHub). Opera is up next (currently awaiting review... which might take a while). 🙃

Tiny Extensions - Open Source Browser Extensions Privacy-focused, open source browser extensions that clean up your browsing experience. Available for Chrome, Firefox, Safari, and Edge.

I’ve been building small browser extensions for a few years, and I finally put them all under tinyextensions.com. They're open-source and privacy focused (no analytics, tracking, telemetry, or data collection). I’ll use this account to share updates, new releases, and what I’m working on next.
