The issue doesn’t occur during normal use of Firefox, but on certain days, it suddenly appears without warning. Specifically, when downloading a file, the download prompt pops up, and after clicking "Download," opening the download menu (or about:downloads) shows that nothing is there, with the message "No files have been downloaded during this browsing session." However, the file has actually already started downloading.
This bug has been present since earlier versions of Firefox and persists to this day. The issue is resolved after refreshing Firefox, but doing so would erase personal data, which I don’t want to lose.

Original Chinese:
在平常使用Firefox的时候并不会出现此状况，但是在某一天没有预兆的就会出现此bug，具体表现为下载某一个项目时会弹出下载提示框，单击下载后点开下载菜单（也可以叫about:download）却发现什么也没有，提示“这次浏览期间还未下载文件”，但事实上文件已经开始下载了，这个bug在很早的版本就出现了，直到现在仍然存在，不知道原因是什么，翻新Firefox后这个问题就解决了，但是这个操作会删除个人数据，我并不想丢失我的个人数据
