These commissions/affiliate-payments become the donations that go to your selected charity.
Latest reviews
- Anatolie Rotaru
- Injects a dialog into sites that asks for donations when the JSON formatter is even not used.
- Michael Vickers
- Ad injector. Into the bin.
- Dan Kleine
- Worked perfectly until now. Suddenly, I'm getting pop-ups saying that JSON Formatter is registered as an affiliate when I make purchases and that I can select donation targets. This looks like the extension is a scam now. I uninstalled it immediately. Edit: The original package is available as „JSON Formatter Classic“ now. This one here is a commercial addon now, see archived GitHub source repository.
- Mattias Olsson
- INJECTS messages on checkouts etc. STAY away from this extension completely.
- James Skemp
- At some point it was updated to show popups on select pages. Not obvious that this extension was adding them, required an additional click to find this. No option to disable. So sadly I need to remove this extension. Did work fine for its original purpose.

- Keir Lewis
- started injecting annoying popups into the browser
- FW Extensions
- I guess we'll see how long it takes for all these 1-star ratings to make a dent on the extension's previous good will...
- Steven McKenzie
- As plenty of other people have said, this now ties into a popup script that shows up every time you visit certain cart pages, trying to coax you into donating to a variety of different services. It "claims" there's an opt-out feature, but the popup modal has no such option to opt out. Uninstalling for obvious reasons.
- Martijn Hermans
- this is now malware, as it includes a script on checkout pages (and all other pages as well). don't use it.
- Mikael Johansson
- This looks like a new Honey extension scam. People please don't support things like this.

- Shepherd Admin
- Lots of popups 😔

- yu pl
- How it works?
- Damir Djordjev
- This bs doesn't work. When I try to use it it just goes to extension manager.
- Yang Fan Yun
- Ads and "checkout" - this is a scam now. Make sure you uninstall this extension!
- Alamin
- There is no option to collapse and expand all. By default all of them are expanded which is very annoying.
- Philippe Ribault

- Paul Iannazzo (PPPaul)
- good dark mode support
- Gareth Johnstone
- While I'm sure the latest update had good intentions of "making a living" and doing a bit of charity - this kinda feels like the whole honey extension all over again. This new popup popped up at the worst possible time while ordering a prescription for my daughter - really didn't sit right with me, tracked it down and uninstalled - just going to find another way to handle JSON in the browser. Good luck, hope betraying your 2 million install base was worth it!
- Nick Humphries
- They have injected malicious code into their plugin. Ads and "checkout" - this is a scam plugin now. Make sure you uninstall this plugin.
- Mathew Keegan
- Whilst well-intentioned, the newly injected donation pop-up is a serious red flag. From a user perspective it appears without warning, which immediately raises concerns about browser compromise or malware. Its timing is particularly problematic - appearing during checkout, precisely when users are about to enter sensitive credit card information. The burden is then placed on the user to investigate what this pop-up is and how to disable it. That is not a reasonable expectation, and it undermines confidence in the extension. This change is likely to result in a significant loss of trust. It is a clear misstep, and I, like many others, will be uninstalling the extension and looking for an alternative.
- Lijia Zhang
- As others have said, the GIVE FREELY pop-up will show up whenever I'm checking out. It is extremely annoying and not what this extension is supposed to do.
- Márton Kissik
- I couldn't care less that it's for a good cause, but when I install something, and expect that something to only do what it is advertised to do, and FOR WHATEVER REASON IT DOES OTHER THINGS WITHOUT ASKING ME, it's an instant uninstall.
- Buster Neece
- The latest version of this plugin now injects code into various "partner" web sites offering to donate a portion of your purchase to various charities via a service called Give Freely. A portion of the affiliate revenue also goes to the maker of the browser extension. This is a huge departure from the scope of this extension, and the opt-out nature of it is both disruptive to web sites where the plugin should not be present or enabled *at all* and a violation of user trust and confidence. This is NOT how you sustain a project like this.
- TJ Horner
- The latest version of the extension introduced a donation pop-up injected into every page provided by a service called Give Freely. There is no indication that these pop-ups originate from the JSON Formatter extension unless the user clicks a small "Why am I seeing this?" link in the bottom-right. While the developer's intentions appear good and I wholly support the effort to fund development of this useful open-source extension, it is unacceptable that this pop-up injection is opt-out rather than opt-in. This is an egregious violation of user trust and is seriously unethical. Please consider announcing this change more transparently and providing users the option to opt-in if they wish.
- Devin Price
- This extension caused a serious issue for us. A donation pop-up appeared on the checkout page of our production ecommerce site. I initially believed we were experiencing a script-injection or security incident and called a meeting with our engineering team, only to find the source was this extension. We did not opt into this behavior in any way, and company leadership was unaware of it. Introducing unexpected UI or injected code on checkout pages—especially without explicit consent—creates real operational and trust risks. I’ve used this extension for over five years, but unfortunately need to uninstall it now because I can no longer rely on it as a safe development tool. @Callum I’ve read your other comments and believe your intentions are good. That said, a JSON formatting extension is not expected to inject any behavior—especially on production checkout pages—and doing so is, in my view, a misguided approach.
- Bernd Kilga
- Beware: Extension now tracks the geolocation of the user.
- Paq (Forcir)
- Used this for years, it's been the first extension I installed on any new device. Noticed it started injecting a give-freely element and it feels scummy. Wouldn't recommend this anymore. Disappointing.
- Brandon Young
- Don't install. Puts donation ad popups on ecommerce sites.
- Joel Doyle-Tremblay
- Used to be a good little extension, but now it adds custom HTML in every websites about some give-freely something. I'll try to find an alternative...
- Rob Phillips
- Oh dear, developer trying to sneak unrelated things on his users. uninstalled
- Ajay Kumar
- All working good, but suddenly on some shopping sites, it shows the advertisement from "Give Freely" I clicked on the link "Why I am seeing this" which was written in very small text. https://givefreely.com/charity-ad-why?p=jsonformatterprod I did not like this, this is very wrong way of injecting content. Please remove this feature or partnership or whatever it is. I've disabled this extension now. Thanks
