2024-01-17 downloador Doesn't really let you control what domains to use or not use CORS on, whitelist acts as a blacklist as opposed to "whitelist". Kind of disappointing how the creator failed to implement a basic feature.
2024-01-02 - firefox is without payments now, so this tool enables them. unfortunately the whitelist acts opposite as expected, i'd of course like to whitelist certain banking apps. No matter what is the interpretation of it, I'd expect whitelist to be blacklist at the same time, depending if main switch is on/off.
2023-11-11 Xarth I just installed this. I'm learning react, and even with Vite, I was getting CORS errors to a particular API. This extension does work, and so does the test site. You might need to go into the options page and allow headers. I also set the origin to *. Thank you.
2023-09-06 HeartyTomato This no longer works as of September 2023; even on the test site the addon provides.
