OMP Send Context od Marlen

OMP Send Context is a Firefox add-on for sending selected text from ordinary HTTP(S) pages with the page URL and document title. Press Ctrl+Alt+K on Linux or Windows, or Command+Alt+K on macOS, or right-click a selection and choose Send selection and link to OMP. Context is sent only when you explicitly invoke the shortcut or context-menu command; the add-on never sends page data automatically. GitHub pull-request pages retain richer title, link/permalink, and GitHub prompt metadata. Diff selections include human-readable file path, original or modified version, added, removed, or context change, selected line range, and the explicit head commit when the page exposes it. An exact diff permalink may also be included as link context.

The add-on requests persistent access only to ordinary HTTP(S) pages so the keyboard shortcut works without a prior toolbar click; it does not request access to local files. Native delivery is optional: without the Linux native-messaging host, the add-on copies the context packet to the clipboard. To enable native delivery on Ubuntu 26.04 (Resolute), install the host package:

sudo add-apt-repository ppa:klondikemarlen/omp-send-context
sudo apt update
sudo apt install omp-send-context-firefox-host

For Snap or Flatpak Firefox, also run sudo apt install xdg-native-messaging-proxy, then run omp-send-context-install-firefox-host --sandboxed as your normal desktop user, without sudo. Start a fresh OMP session and restart Firefox after installation. Full instructions are available at https://github.com/klondikemarlen/omp-send-context#firefox-native-messaging-host-linux-setup.

The add-on omits ambiguous diff location metadata and rejects Firefox internal and file pages, protected Mozilla pages, empty selections, and other unsupported inputs without delivery.
