i want my firefox browser to be working well with my connection, now its not working

f Firefox suddenly feels slow, I’d first figure out whether it’s actually Firefox or the connection itself. Try opening the same sites in another browser. If they’re slow there too, it’s probably the connection, not Firefox. If only Firefox is slow, restart it and check for a bad extension or too much cached data. You can also try''' Settings → Network Settings → Settings,''' then make sure Firefox isn’t using a proxy you don’t need. Sometimes a simple setting like that can make browsing feel much worse. If you can share a little more information. what exactly is slow, whether all websites are affected, and what device you’re using.we can narrow down the problem.
