@zalex108 I did contact them. Let's see if they will respond. Thanks.

@zalex108 No instructions on how to use it are there either.

So anyone can answer my question? Thanks.

@leocg Yes Gif Booster is an Opera extension.

@leocg Using Opera of course.

How do I use Gif Booster to post gifs in Facebook?

Using a PC w/Opera browser, there is no Autoplay Videos option in FB video settings.

@leocg Indeed, it doesn't seem possible to do it in the way I wanted. What I have done instead is to log in to every webpage using IE, then copy the link (web address), and add it to the Opera Speed Dial. Now my question: Is there a way to group all these webpages on the Speed Dial into folders according to subject?

By IE 11 folder I mean a folder with many web site links which I visited and saved using Internet Explorer. I wish to transfer it to Opera browser, so that I can visit all websites using the Opera browser. Please explain in detail the steps, and/or give me a link which describes how to do it. Thanks.

What is the easiest way to transfer an IE11 folder to Opera, without having to log in to each website included in the folder one-by-one using the Opera browser?
