我全新安装了 Ubuntu 18.04 仿生。我已经从synaptic、软件中心和mozilla bundle安装了 Firefox 。我已经完成了about:config以及对流水线、网络、代理等进行的任何检查，都做到了。
它仍然滞后于youtube播放、每次从youtube重新启动时退出、滚动等。
我怀疑我的问题是我的firefox 插件，我一一禁用了它们，重新启动了 firefox，但没有看到任何改进。
广告拦截器- 删除没有改进
幽灵- 删除没有改进
duckduckgo 隐私要点- 已删除，没有改进
chrome 没有遇到任何这些问题。它活泼流畅。任何人都面临同样的问题，或者有任何想法要解决。

我确实从 oracle java 下载了软件包，但如果我尝试更新或安装任何软件，我仍然会收到此错误。
如何解决这个问题？
我知道 Flash 播放器有问题。就我而言，我有 64 位 ubuntu 12.04 系统。Youtube 视频工作正常，GIF 工作正常，甚至我玩过 Flash 游戏。但问题是，当我打开starsports.com 并点击它说需要Flash 播放器的任何视频时。同样在迷你剪辑上，我什至看不到游戏加载。这里有什么问题？
