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.

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.

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.

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.

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.

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...

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

Started injecting popups into checkout pages. Malicious and misleading. Do not install.
