I've only started having this problem recently. After upgrading to an ethernet cable and getting much faster internet speeds (around 70mbps on the speed test), I've noticed that for whatever reason, Firefox is actually running slower than it did when I had worse internet connection through Wi-Fi signal. Websites can take minutes to fully load. When checking the task manager, it shows that Firefox's network speed is either 0.1mbps or 0mbps. This can be somewhat inconsistent, for example YouTube's homepage is able to load somewhat quickly, however videos can take a few refreshes. This is also sometimes a problem on a few other programs like Discord, but it's never been a problem on Edge (which is where I'm writing this). Is there any way to fix this?
