FeHelper是一个功能强大的开发者工具，专为前端开发者设计，集成了多种实用工具，帮助开发者提高工作效率。**但是，FeHelper严格遵守单一功能启用原则，默认情况下，FeHelper只提供JSON自动格式化的功能，其他所有功能都是默认关闭状态，如果用户有需要，可以自行前往插件配置页面进行安装开启**；以下是FeHelper的主要功能：
## JSON工具:
- JSON美化工具：自动检测并格式化JSON数据，支持手动格式化、乱码解码、排序、BigInt处理、编辑、下载和皮肤定制等功能，极大地方便了开发者对JSON数据的处理。
- JSON比对工具：支持两个JSON内容的自动键值比较，并高亮显示差异点，帮助开发者快速识别数据变化。

目前还存在字体默认增加了反锯齿的问题，导致字体很细，望修复
支持一下，感谢提供这么好的工具
辛苦了， 但是排查到这个插件的问题 确认不容易。太惨了.. 我都把浏览器更新了
这8px折腾我重置了两次chrome才找出来哪里的问题
竟然给.item注入了一套新样式，搞得页面全废
为啥改我页面样式？？？ 害的我找了半天 我真特码服了
为啥改我页面的样式？
（2022.12.1616）此版本会造成 body强制多了 padding 8px，严重影响体验，请抓紧时间修复
会给我的body注入一个奇怪的padding: 0 8px;不知道是啥原因，关掉插件就没问题。
json格式化非常方便，赞
