Latest reviews
- (2023-08-10) Justin Medina: Seems like it could be useful. Icon is greyed out / not accessible. Also shows an error in the console.
- (2023-04-18) Enrico Lamperti: Would be great to have a Firefox version!
- (2023-03-02) Josh Williams: Thank you GB for making this easy tool! Makes testing much easier for our experiments in all environments.
- (2022-05-09) Tyler Barber: Makes managing Growthbook feature flags in browser a breeze! Does only work on JS SDK, so you'll need to find another way to handle server-side flags, but opting in and out of browser features is painless thanks to this extension. Would love to see this be made available to other browsers!
