Hi, thank you for your comment. I plan on using react later to expand the features the popup has. There have been quite a lot of requests for this. As well as an options page. I may switch to a smaller library in the future. Adding react also helped fix several UI bugs, and makes the current UI easier to build on.

FWIW, adding react only adds ~35kb to the packaged file, a %15 increase. Unpacked it is ~120kb. However the public suffix list, and multi-domain first party list combined are 160kb. So I didn't think it was a very significant size bump.
