Hello,
I believe what might be causing the slowdowns are the antivirus plugins that you have, both Malwarebytes and Norton browsers plugins are installed, normally you should only have one antivirus, having two run at the same time will scan the links twice, and will be doing the same job twice for double the effort and likely the same result.
I suggest removing one of the antivirus plugins, it should get your edge running back at normal speeds.
Hope this helps,
JC
