Git Fox Tab nga Artem Utkin

A Firefox extension that reads all open tabs (and tab groups) across every window, saves them locally, and exports them to a Git repository (GitLab or GitHub) using a token.

Features
* Collect tabs from all windows — every open window is captured and tabs remember which window they belonged to.
* Tab groups — native Firefox tab groups (Firefox 141+) are saved with their name, color and collapsed state.
* Containers — Firefox Multi-Account Containers (contextual identities) are saved as an additional grouping mechanism.
* Push to Git — writes the saved tabs as a JSON file to a GitLab or GitHub repository using the REST API and a personal access token.
* Pull from Git — load saved tabs as a JSON file from Gitlab or Github and restore its original window.
* Manual import / export — download a JSON file with your tabs and re-import it (e.g. to move data between machines).
* Restore — reopen the saved tabs grouped by their original window.
