Why is it taking way too long to open websites on Firefox lately?

Is there any VPN or antivirus to try disabling for a bit? There's no troubleshooter data attached to this question, but the first factor to verify on Windows stalled secure connections is: What is your antivirus/phishing/malware software or security solution provider, and what happens if you disable it (or its "safe browsing" features)? Other than that, the best thing to do is to compare in Private Window, then restarting into Troubleshooter Mode or eventually creating a separate testing Profile to see how existing site data impact that. The steps to go through are from the easier to the complex ones: # Please check if you have [[Enhanced Tracking Protection in Firefox for desktop|Enhanced Tracking Protection]] (ETP) enabled. You can do that by clicking the shield [[Image:Fx89ShieldIcon]] icon in the left part of the address bar. #* If ETP is enabled, try disabling it. # If the problem is not fixed, try [[How to clear the Firefox cache|clearing Firefox cache]]. # If it does not help, try [[Clear cookies and site data in Firefox|clearing cookies and data]] for the website you experience troubles with (''warning: you will be logged out on this website''). # If it also does not help, try [[Diagnose Firefox issues using Troubleshoot Mode|running Firefox in Troubleshoot Mode]]. If the problem doesn't persist, please follow the steps from [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems | this article]] to troubleshoot further. # If nothing from the above helps, try [[Manage Firefox profiles|creating a new Firefox profile]] and check if the issue persists there. If it doesn't, you can [[Restore bookmarks, passwords and data from an old Firefox profile|start copying files from your old profile to the new one]] to identify which one causes the issue. See [[About your important data and their files|this article]] on what files to copy. But hopefully none of the more complex steps will be necessary, this looks either like a VPN / antivirus incompatibility, or something similar stuck in the networking itself.
