LoginSecure Slideshow: Will it slow down your website?

Due to the extension, your website will not become slower. But depending on the content that you put into the slideshow it can increase load time. 

If you, for instance, configure the extension to play video files immediately and you add a background video and two content videos. Then all these 3 videos need to be loaded whilst the page is loading. And this will increase the load time. Therefore we don't recommend to play all video elements immediately.
