Slow browsing on Firefox


[link to this post]
 
I'm noticing pages take an age to load on Firefox (45.0.1, the current version) on Windows 10. Speedtest shows nothing out of the ordinary (download 64.7, bursting to 74 Mbps, upload 17.6, bursting to 18.2). Microsoft Edge is fast, as it always is. Any thoughts, anyone?

Fine for me - same version of Firefox, and Windows 10, and my speed test is omly 7-8Mbps download (fine for me).

Have you cleared FF's internet cache lately, maybe it's getting overly clagged up?

Could DNS problems cause it?

Thank you, Tony, but unfortunately hasn't made any difference. Don't seem to be any DNS problems either, as far as I can tell.

Have you - knowingly - made any recent changes to your system?

Are there any FF add-ons that might be causing a problem?

Have you changed the FF about:config area?

...struggling for more ideas to be honest.

Try running the Win 10 compatibility troubleshooter on it. That sorted a similar problem I had with Chrome.

You got Flashplayer running (as in the addon within Firefox) by any chance?

Thanks, everyone, for your suggestions. It's a Kaspersky thing (I should have realised this earlier, as the problem started after I'd updated to Kaspersky "Total Security" 2016). It injects a piece of Javascript in every web page browsed by Firefox or Chrome, of this form, every ?200 milliseconds:

http://ff.kis.scr.kaspersky-labs.com/some string here/main.js

Apparently this has been known for some time, and apparently Kaspersky refuse to acknowledge this as a bug - see here: https://forum.kaspersky.com/lofiversion/index.php/t3... , where one of the posts shows how to get rid of it:

(In Kaspersky): "settings>protection>Web antivirus>Advanced and there you see Kaspersky Protection extension check box."

(Editsmile Well, the above didn't work, but this does: edit the hosts file in Windows\System32\Drivers\etc and add this line:

0.0.0.0 ff.kis.scr.kaspersky-labs.com # Kaspersky anti-injection for Mozilla Firefox

There's a discussion of it here: http://superuser.com/questions/981959/how-to-disable...
