I use Firefox, but it happens also with Chrome and Opera.
I do not like IE.
I have the latest updates of the browsers and the Adobe Flash Player.
From time to time, often, when I play videos the browser crashes.
It happens often on YouTube, but also on Facebook.
It did not happen in the past.
My notebook is Thinkpad T410s, Win 8.1, 64 bit, 8GB RAM, 128GB SSD and works quite well.
Please provide some suggestions how to solve/correct the problem.
P.S. My PC is not a calm one, with the same programs long time steady. I install/uninstall, test different pieces of software. That may be the cause of the crash.
I never understood why the smart engineers from Adobe must update so often and so many times Adobe Flash Player. I really hate that.
