User Reviews
Users largely agree the extension can solve CORS issues and is easier to configure than alternatives, with a clean, friendly UI when it works. However, many reports indicate it often stops working or doesn’t save changes/URL rules across Firefox versions, and sometimes blocks legitimate behavior by other apps (e.g., YouTube). Compatibility varies widely across Firefox releases, developer editions, and operating systems (macOS, Android) or requires pages to be served (not file://). Some users also find the settings unclear, especially about regex handling and who controls the URL list. Overall, it’s promising but unstable and platform/version dependent. Pros
- Can solve cross-domain/CORS issues when it functions.
- Easy to install and configure.
- UI is clear and user-friendly compared with other CORS plugins.
- Some users consider it a lifesaver for development.
Cons
- Frequent issues with functionality and changes not saved across Firefox versions.
- Rules (URLs/regex) often fail to save or apply correctly.
- Compatibility problems across Firefox versions, editions, and OS (macOS/Android) or after updates.
- UI can be confusing or unclear about how settings work.
- Does not work on local files (file:// URLs) and requires pages to be served from a URL.

Is Cross Domain - CORS Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Cross Domain - CORS requires a few sensitive permissions. Exercise caution before installing.
Risk impact analysis details
- Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
- High ****** *** ********* ** ******* *** ******* ******* ** ****** *** *** ******** ******
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
Cross Domain - CORS is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
