I was wondering if there was a way to prevent a website from taking me out of fullscreen mode? I use TubePlus.me and they serve ads on their pages - revenue - I get that. However, when I watch a video and put the page into fullscreen mode, sometimes you can see the video start to "lag" or "stutter" throughout the video... and then many times right after it does this, the page minimizes out of fullscreen mode. My guess is this is happening so their ads will be seen again, because in fullscreen mode no ads can be seen / heard, etc. How do I prevent this from happening and persistently stay in fullscreen?
After doing a little more checking, it appears the videos on the page are delivered in Flash - I have ver 18.104.22.168. It is possible that something in Flash is being exploited to minimize the screen??
Another possibility is my anti-virus.. (Rarely, but I have had my anti-virus activate when using the same site that is minimizing - TubePlus.me) I am using Kaspersky Internet Security 2013. I know it has a System Watcher feature that could possibly be doing this. Per their help section:
•Controls executable files started from vulnerable applications and web browsers (for example, an attempt to run an executable file by a program designed for viewing documents).
•Controls suspicious actions of vulnerable applications (for example, if the rights of a running vulnerable application are exceeded and it writes itself into the other processes’ system memory).
•Monitors previous program starts (for example, whether the program was started by the user or by an exploit).
•Tracks a source of a malicious code (for example, a web browser that started download of an infected file; remote web address).
•Prevents using application vulnerabilities.
