In the past few days I have been experiencing periods of extreme sluggishness from Firefox, even where it takes seconds for each character I am typing on the keyboard to appear in a dialog box or in the URL bar. I just updated from Kaspersky Internet Security 2013 to Kaspersky Internet Security 2015 less than a week ago, and I see a bunch of extensions and plugins that it has added, some of which boggle my mind as to why they would even be added in the first place, because they appear to be for Chrome! In trying to resolve this slowness, I want to DISABLE these extensions and plugins.
I have tried to disable all of them in Firefox, but when I restart Firefox, they are enabled again. I have looked through the settings in Kaspersky and done the following:
In Kaspersky settings for "Web browser extensions" I have unchecked "Automatically activate appliaction plug-ins in all web browsers".
For Kaspersky URL Advisor I have unchecked "Check URLs".
I have even turned off Kaspersky for a period of time, but still they all stay enabled if I restart Firefox.
This sluggishness is causing me money. I can't always restart Firefox as I will lose something I've been working on. I need to disable these add-ons so I can determine if one or more of them is the problem. I paid for Kaspersky, it doesn't seem right that I would have to get rid of it altogether to solve this problem.
This is what I can't disable:
