Compare search results side by side on https://side-by-side-search.vercel.app/!
This extension is necessary to enable search on https://side-by-side-search.vercel.app/
It will drop X-Frame-Options and Content-Security-Policy HTTP response headers, only on pages in frames on the search site, allowing all pages to be displayed.
Should be used only temporarily and only for development, testing, or troubleshooting purposes because it disables important browser security mechanisms.
Once the extension is installed you will be prompted to install side-by-side-search a search engine. This way you will be able to search from your browser's search bar.
