Poor performance of Fire Fox browser

Concept_Designer

I been using FireFox for at least a decade I am really disappointed in it's current state. It is very slow OIS is Version 26.6.2 (25G83). Constantly telling me it can't find server when I hit an website link? Also frequently says secure connection? I want my FireFox back.

I’d start by checking whether Firefox itself is up to date, then try Troubleshoot Mode to see if an extension or setting is causing the slowdown. The “Server Not Found” and “Secure Connection” messages can also come from DNS, VPN/proxy settings, security software, or an incorrect system clock. Mozilla has troubleshooting steps for both issues.

Since Chrome is working normally, I’d especially check Firefox’s DNS and connection settings. Hope you can get your old Firefox back!

Do you use any security solution (from companies as Malwarebytes, Sophos, Symantec, SentinelOne, Fleet and similar)?
