for now, iam on firefox and was thinking would be fun to change the user agent to a more customized way

https://addons.mozilla.org/en-US/firefox/addon/user-agent-switcher-revived/

any known negative impact on system?

Switching user agent doesn't actually do a lot other than tell a website what browser is accessing the site, pretty much pointless with today's websites and can be more of a privacy issue than anything.
