- Alice Katerina Graham
- Started injecting popups into checkout pages. Malicious and misleading. Do not install.
- Joey Jan
- Started trying to do popups, uninstall immediately.
- Ader Pen
- works
- Brandi Flowers
- Love this extension. Simple to use. Easy to switch back and forth to see the raw or formatted json. Lightweight... and handles a large json output. Super easy install.
- Lyden Nee
- Recently started seeing the following from this extension: core.js:297 Uncaught (in promise) Error: No checkout popup config found at core.js:297:55043 at async Y1 (core.js:297:54962) A JSON formatter has no legitimate reason to load any checkout or popup payment code. Uninstalling immediately.
- Jake Holman
- Seems to have included some sort of injection into the latest update, with a div being added to all pages with the id of "give-freely-root" which seems highly suspect.
- Chris Beck
- started popping up donation stuff. as amazing as that might be, I don't want it appearing while I'm coding. (( Callum's explanation lower is fair, but maybe an opt-in or some other sort of notification would be better than surprising users. mind you it's almost certain that more of us should be supporting the extension ))
- Noah Witjes
- I rarely leave reviews, let alone on a chrome extension, but the recent 0.9 update prompted me to write one anyway. I fully agree with Matt Candlejack. Something as intrusive as Give Freely, a service which for it to function HAS to parse every single URL you visit, is not something that should be dropped on 2 million users without any notice, let alone be enabled by default. The explanation for Give Freely makes total sense, however there is no guarantee that Give Freely will change their stance on how they process data in the future. Additionally, the setting to disable the Give Freely appeal is hard to find and not accessible by pressing the extension's icon in your task bar. Truly a shame that such an old and reliable extension forces this on its users with no given warning. I wish the dev had chosen a different way to make some money and support charity.

- Got a popup for Give Freely, while a noble cause this is intrusive and should be opt-in at the bare minimum instead of forcing adware - had this installed for a while but will not support this developer further.
- Sharon Cohn
- works well - json loads. ran into no issues
- Pontus Frödén
- Shows popup on "partner" pages where we are given to option to support charity. This sounds like they are doing a Honey, they take over any existing affiliate cookies and changing it so they get it instead. I am sorry but I can't support affiliate where you is not the one sending the user to the store. Removed and will never use again.
- Ayyash Ayyash
- after last update started throwing an error in every page i visit in console (even localhost) throw Error("No checkout popup config found");
- Alex
- Contains adware.
- Martin Malinda
- This extension contains adware in the source code.
- Jimmi Hansen
- Stopped working. Shame the developer doens't update it any more.
- Francisco Esteves
- Copying the parsed output via ctrl+A does not provide a formatted/indented output. Would be a 5stars extension if it would do that
- Faizan Amin
- this app started displaying popup ads app is garbage now
- Murilo K
- Seeing long json is a pain after the latest update. It seems it loads the json partially and there's no option to disable that.
- Amol Patil
