Debugger for Firefox
Verified publisherWhat a VS Code verified publisher badge means, compared with Open VSX →
Debug your web application or browser extension in Firefox
Tracked since 5 Sept 2026
Daily readings on both stores, taken by us. As of 24 Sept 2026.
Each bar is one day’s change in the store’s own counter. Open VSX counts a download on every update, so a day includes updates by people who already had it. Days before 5 Sept are reconstructed from public archives rather than read by us.
