Allow CORS: Access-Control-Allow-Origin
Description from store

Allow CORS: Access-Control-Allow-Origin lets you easily perform cross-domain Ajax requests in web applications.

Simply activate the add-on and perform the request. CORS or Cross-Origin Resource Sharing is blocked in modern browsers by default (in JavaScript APIs). Installing this add-on will allow you to unblock this feature. Please note that, when the add-on is added to your browser, it is inactive by default (toolbar icon is grey C letter). If you want to activate the add-on, please open the toolbar popup and press the toggle button on the left side. The icon will turn to an orange C letter.

If you have a feature request or found a bug to report, please fill out the bug report form on the add-on's homepage (https://mybrowseraddon.com/access-control-allow-origin.html).

It works. Whitelist could work better, but it's still better than nothing. Firefox analogue didn't work for example.

Riaj Ikbal 2024-04-08

i was creating and youtube clone and using external apis before using this extension my app was running fine but after using it my apis were blocked by youtube and my api keys were useless so i uninstall it

Serhii Klochko 2024-04-04

It does work, but you have to add a "Custom CORS rules" rule for localhost at the bottom of the extension options, e.g. https://localhost:5173 | PUT, GET, HEAD, POST, DELETE, OPTIONS | * | true.

After hours of looking at CORS solutions and try them without success, this worked like a charm on Chrome Version 117.0.5938.132 (Official Build) (64-bit), June 2023. Thank you very much! I recommend it and for sure will make a donation

There is a toggle icon on the left side to turn on the plugin, toggle it and ensure the plugin is activated, . Worked fine after this step.
