Very high CPU usage. Makes my computer slow to a crawl.

Huge resource problem... Memory leak ?

high cpu load and ram usage for no reason

It does what it needs to do, true. That's why I won't rate it it with a single star. But it is causing an insane CPU use on my Mac, draining my battery within an hour. Took a lot of work to find out the cause. Please fix this ASAP!

花兩天時間，以爲是firefox更新造成用掉一核的cpu，安裝舊版的firefox狀況一樣，一個個將附加元件停用終於抓到這個11月6日更新造成，這個問題明顯又嚴重，您們釋放新版本沒有測試。

Massive resource hog. Why? It took me forever to figure out which extension was hitting the processor so hard in comparison to everything else, and it turns out to be this one.

Hey, developer. What gives? It works great, but at what cost?

It does work. But I had to restart my browser.

в целом, нормально

Thanks. Too many website logins break without this addons.

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.

update: it's memory and cpu hog, avoid

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.

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.

This no longer works as of September 2023; even on the test site the addon provides.

Nope

Helped me bunch of times, thx.

It worked for me!

Even on the test site it always tells me, that cors is blocked.

Does nothing.

CORS issues were driving me completely nuts in development. I tried a few other CORS add-on first but could not get them to work. It took a bit of fiddling, but I put this down to CORS idiosyncrasies. Once I worked out what to do, a few short clicks this app have restored my sanity, such as it is. Thank you!
