Grab extension per Grab Extension

Grab Browser Extension

Send browser downloads straight to the Grab download manager — no more juggling browser download folders.

What it does:

Automatic interception (off by default): optionally route browser downloads to Grab instead, with size filters and file-type exclusions
Right-click menu: "Download with Grab" on any link
Alt+G: send the current tab's URL to Grab
Video detection: finds playable videos on the page and offers them in the context menu

How it works:
The extension talks to Grab over a local HTTP endpoint (127.0.0.1:9412) — no setup, no native messaging host, works from Flatpak. If Grab isn't running, downloads stay in the browser.

Requires: Grab 5.7.0+ for automatic interception.
