Browser extension stores app marketplaces

Stores distributing browser extensions that run in the page context and reach end users directly.

6 marketplaces in this directory match this tag.

Browser extension stores — Chrome Web Store, Microsoft Edge Add-ons, Firefox Browser Add-ons, Opera Add-ons, Raycast Store, Safari Extensions — distribute extensions that run in the page or OS context and reach end users directly, without a business admin in the loop.

Chrome, Edge, and Opera all run the same Manifest V3/WebExtensions model, so a single codebase can reasonably target all three; Firefox supports both MV2 and MV3 and leans on open code review; Safari requires wrapping the extension in a native macOS/iOS app. Chrome Web Store has by far the largest audience among them and the strictest policy enforcement.
