When Kaspersky is running (even with protection disabled),
1. I can’t manage my playlists on youtube: the button to add a video to a playlist doesn’t respond.
2. I can’t post comments under a youtube video: a red “error” displays under the input box.
3. I seem connected to my youtube account, there is my avatar on the upper right (on computer), but the left menu asks me to connect by clicking on a button that leads to an error page from Google: “405. That’s an error. The request method GET is inappropriate for the URL /youtubei/v1/guide. That’s all we know.”
Only occurs on FIREFOX. No problem with other browsers.
How can I make Kaspersky work well with Firefox ?
