Browser Extensions

" summary

Claims that Firefox now implements Chrome's extension model as web extensions and that most Chrome extensions run with minimal changes. Tools demonstrated include web-ext for scaffolding and live reload and a compatibility checker (extensiontest com) that analyzes CRX files. A mentioned surprise: a Chrome extension will 99.9% work in Firefox but only ~68.4% in Edge. The webextension polyfill is used to normalize callbacks to promises; cross‑browser porting mostly succeeds, with API gaps flagged by the tester.
