Kaspersky Plus hanging firefox

[GGiuliano93]

Hello, i have a problem with kaspersky and firefox, if i install kaspersky firefox will hang out using google or generally browsing, it will hang just one tab (freezing completly) but i can use other tabs/functions. It's pretty frustrating because everytime i search something on google i have to wait like 10+ seconds...

We have filled a bug on mozilla website: https://bugzilla.mozilla.org/show_bug.cgi?id=1847066

But if i uninstall kaspersky the problem it's gone, how can we fix this?

Thank you

Update: I uninstalled and reinstalled kaspersky, and the problem was present again, so in my case the problem it's kaspersky.
Then i noticed that kaspersky recommends you to install the extension on firefox (Kasperksy Protection).
I installed the extension and rebooted firefox. Now with the extension installed in firefox the problem it's gone.
So my guess it's there's a bug in kaspersky if you don't have the extension installed.
Hope it helps.
