中文原文 您好， 非常感谢你们提供了火狐这个十分好用的浏览器。 但是我在使用上出现了一个小瑕疵，希望你们能够尝试优化这个问题。 我的侧边栏总是不够灵敏，即便我打开了 “悬停时展开侧边栏”，它也会经常性无法展开。 还有一个就是，它经常在我需要使用一些网站的侧边栏的时候冒出来，即便我还没有碰到它。 我认为这两个问题修复了后，会更加的好用！ AI 翻译结果 Dear Sir/Madam, Thank you very much for providing Firefox, such a useful browser. However, I have encountered a minor issue while using it, and I hope you can try to optimize this problem. My sidebar is always not sensitive enough. Even though I have enabled the "Expand sidebar on hover" option, it often fails to expand. Another issue is that it often pops up when I need to use the sidebar of some websites, even when I haven't hovered over it yet. I believe that after these two issues are fixed, the browser will become even more user-friendly!
