Description from store
This plugin allows you to send cross-domain requests directly from browser without receiving Cross Origin Errors.
You can override the Request Origin header with this plugin and also have Access-Control-Allow-Origin set to *.
Update: We removed email list signup and added ability to log and capture API calls. Migrated from Chrome Manifest V2 to V3, due to the new V3 "storage" api, your old settings may need to be reentered.
You can override:
Request Headers: Origin
Response Headers: Access-Control-Allow-Origin, Access-Control-Allow-Methods, Access-Control-Allow-Headers, Access-Control-Allow-Credentials, Access-Control-Expose-Headers

API Logging & Capture:
You can capture any Ajax, XmlHttpRequest, or fetch API requests made by any page, and send to your Moesif account for analytics and debugging.
DISCLAIMER: This tool circumvents CORS security rules baked into every browser and is intended for testing your own website during development. Some production websites like Google Docs or Facebook may complain if they detect something that isn't expected. You can use the whitelist feature to only turn on for some domains. To avoid security issues, it is recommend to turn off after debugging.

- (2025-03-21) The_Dark_Jumper: Great. Only affects hosts that are explicitly whitelisted, very reasonable.

- (2024-06-03) Wayne Mao: The domain whitelist works well, but the plugin doesn't support web fonts. For web fonts, it needs Access-Control-Allow-Origin: * Store doesn't allow me to add a new review, so I edit the previous review to report a bug in recent release: The 'Allow-Control-Expose-Header' should return '*' by default, which is not returning empty Hope the dev team can take a look. The workaround is to manually set the value to '*'

- (2021-06-25) Kristina Mason: I can't get this to work in Chrome, only Edge. I downloaded it in Chrome and it showed very briefly in my toolbar and then disappeared. I can see it in my list of Extensions and it's active, but I can't get to the actual app icon in the toolbar to turn it on or off. The icon showed up with a grey "off" on it, and then disappeared.

- (2021-03-06) Ehsan Alimohammadi: Unfortunately, it doesn't work for me. I used chrome v89 and relaunch, clear cache. I think in new version of Chrome this plugin doesn't work. When I run chrome with --disable-web-security argument, CORS disabled actually but with this plugin I can't. Do you have any solution to solve problem?
