Resource Override

Redirect traffic, replace, edit, or inject content on any website. MV3 Chrome extension (unpacked — not on the Web Store).

Installation

git clone https://github.com/iadvize/ResourceOverride.git
cd ResourceOverride
git checkout mv3

Then in Chrome:

1. Go to chrome://extensions
2. Enable Developer mode (top-right toggle)
3. Click Load unpacked
4. Select the cloned repo folder

After edits: hit the reload arrow on the extension card. For service worker changes, also click Service worker to restart it.

MV3 fork status

Personal fork of the upstream mv3 branch. Goal: restore parity with the V2 feature set under Manifest V3. Not on the Web Store; no new features planned. The following regressions have been fixed:

• Service worker / DNR — dynamic rules rebuilt on SW startup and onInstalled; rules survive worker termination or fresh install/import.
• Script & CSS injection — webNavigation.onCommitted awaits ruleset ready before injecting; CSP/permission failures surface in the SW console instead of being silently dropped.
• File override size cap — fileOverride payloads above 8KB flagged via ruleErrors instead of producing invalid DNR rules.
• Import / Export — Save Rules now awaits exportData(); importer accepts both {v, ruleGroups} and legacy data shapes.
• Editor sync — open editors closed on sync messages so stale buffers can't overwrite freshly synced state.
• Dead code removed — residual IndexedDB layer (src/mainStorage.js, src/keyvalDB.js) deleted; storage is exclusively chrome.storage.local.

Known gaps

From todo.txt: v2 import/migration tool, suggestion staleness after navigation, body-script injection timing edge cases, drag-reorder for tab URL groups, help text overhaul.
