我的 Firefox 每隔几天就会死机。
它说：超出 CPU 时间限制（核心已转储）
有什么办法可以取消或至少提高这个限制吗？

chrt -o 0 firefox似乎有一段时间有效，但现在不再有效。
我检查了是否对任何进程设置了任何 cpu 限制：
grep cpu */limits|grep -v 'unlimited.*unlimited'
这没有造成任何打击。但这列出了所有 firefox 进程：
$ grep realt */limits|grep -v 'unlimited.*unlimited'|G 000
3238579/limits:Max realtime timeout 50000 200000 us
这可能就是原因。但我该如何改变呢？

我禁用了 Snowflake（“tor”）插件，问题就停止了。
