Hello :D

I seem to e having a problem with Firefox in that whenever I use it, my entire internet slows down to barely a crawl. I have tried several things, including turning off efficiency mode in the config.

I have tried various DNS and Proxy fixes I've seen on reddit and these forums, including turning of proxy and dns over https as well as reinstall the browser. It is only firefox that does this to my network.

I got Windows 11 Home edition and my network is a fiber network

Any help would be appreciated.

Keazen oplossing

This question has no attached troubleshooter data, so just in general: some of the most obnoxious reasons are either VPN (or some of their "extra" added features), or antivirus/security software that tries to decrypt the secure connections and effectively stalls them over time.

I don't think you actually see speeds drop (you can measure that with online tools) — it's latency connecting to services and getting components loaded on the pages etc. that you're facing, does that sound about right?

What kind of security offerings you use, and are you able to either try disabling these for a bit to test, or look if they have any "secure web" or "https scanning" features that you'd be able to turn off?

Yeah turned out to be my Anti-Virus. I got AVG Anti-Virus and turning off Enable HTTPS scanning seems to have resolved the problem for now. Will look into switching away from it.

Thank you for the help!
