Random browser connection problems

I don’t know why I’m just now mentioning this…but. I’m having random Firefox connection problems “Hmm. We’re having trouble finding that site.” in Firefox on OpenSuse Tumbleweed probably since I started using this distro. But it’s not tied to every site. Refresh…same thing. Open in new tab…same thing. It’s mostly annoying. Usually I’ll restart Firefox and it will work again…but not always. Never had this problem in another distro.
