I recently watched this video: https://www.youtube.com/watch?v=a5La0XhLIaY
And now every time I open my browser, it is one of my startup pages (although not replacing any of the existing), I have looked in my settings and it is not marked as a startup page. I have also been experiencing other similar issues, such as when I have multiple tabs open and I click the close button, and I don't get it asking me if I want to close all the tabs, it just closes, and launches them all back up again as they were next time I open my browser, I even have a problem where sometimes I go to a site, it is the only tab, I close my browser, the next day when I boot my machine up, and start my browser, it goes to where I left off when I last closed my browser instead of opening my startup pages. These issues come and go though and are likely to just be bugs, however almost every time I start up my browser, it starts the video I stated above, and although it is nice at first, that video really does get a little annoying...
So really that is my question, how can I get Firefox to startup and not have that video as an additional startup page? And why I am I experiencing these very similar issues any way? Bug? Or something else?
If it helps, I am on Ubuntu Gnome 15.04, with Gnome Shell, and Gnome 3.14.
