为Firefox个人定制的userChrome.css和userContent.css
本项目中的userChrome.css已经实现了Firefox原生水平标签栏隐藏和侧边栏自动收起。如果需要Firefox原生水平标签栏，则需要自行修改userChrome.css；如果直接使用本项目的userChrome.css，则需要自行安装具有垂直标签栏功能的扩展。本人目前使用Sidebery。
因为本人尚不能熟练运用CSS，所以本项目中userChrome.css和userContent.css所有的位置/坐标均基于本人的使用环境，不一定具有可移植性，仅供参考。在其它设备和浏览器上使用时，若发生错位或显示异常等问题，请自行调整。
Personalized userchrome.css and userContent.css for Firefox
The userChrome.css in this project has already implemented the hiding of Firefox’s native horizontal tab bar and the automatic retraction of the sidebar. If you need the Firefox native horizontal tab bar, you need to modify userChrome.css yourself; if you use the userChrome.css of this project directly, you need to install an extension with vertical tab bar functionality yourself. I am currently using Sidebery.
As I am not yet proficient in CSS, all positions/coordinates in userChrome.css and userContent.css in this project are based on my usage environment and may not be portable, for reference only. When used on other devices and browsers, if there are problems such as misalignment or display abnormalities, please adjust by yourself.
