1.2.0 — site exclusions testing prototype

Backspace to Go Back 1.2.0 — testing prototype

Maintained fork of oslego/chrome-backspace-back; upstream history and attribution preserved.

• Backspace back / Shift+Backspace forward, with safer editing/composition/modifier/repeat handling.
• One-click site exclusions, parent-aware toolbar state, options management and Chrome Sync storage.
• Boundary-aware domain/subdomain matching; no service worker, frameworks, telemetry or runtime network requests.
• Runtime-only ZIP: extract it, open chrome://extensions, enable Developer mode, Load unpacked and select the folder containing manifest.json. Disable the original extension and reload existing tabs.

Verified: final master 8b9c8580a8d8516664f7d4c9c8fd594574e6136b passed all hosted gates: https://github.com/pupontech/chrome-backspace-back/actions/runs/36894424083 . 44 Node tests; genuine headed Chromium tests against both source and extracted ZIP, including text editing/open+closed shadows, live exclusions, same/cross-origin frames and restart persistence. Ubuntu/Windows unit jobs and Windows source+ZIP browser harness also passed on the final feature head: https://github.com/pupontech/chrome-backspace-back/actions/runs/36894092154 . Independent Luna review and targeted regression/fix re-review passed.

This is a prototype for owner testing, not a claim that every manual Chrome acceptance item is complete. Still untested: native toolbar user-gesture/activeTab grant in the owner's stable Chrome profile, physical IME/held keys, named third-party editor implementations, cross-device Chrome Sync, Edge and Brave. Popup/controller states have unit coverage; automated browser proof opens the popup document as an extension tab, not a native toolbar click.

Licensing: upstream has no explicit LICENSE, package license field or source license header and GitHub detects no license. No license was invented. Original code/icon rights and attribution remain with their holders; see README. No Chrome Web Store submission.
