Is fontSwap - Custom fonts for every website safe?
fontSwap sends extension error reports that can include the current tab URL to a Cloudflare Worker.
fontSwap installs error reporting in its background and popup code and posts error details to a Cloudflare Worker endpoint. When content scripts report errors from pages where font rules run, the background handler can append the sender tab URL to the error stack before sending it.
