This is a brand new laptop with great specs. The vast majority of my programs are on my older laptop, and I only use this new laptop for the bare essentials. So no chances of viruses, etc. I only have simple programs like Notepad++. So it seems too often, most of the time, just opening a new tab in Firefox Portable will cause the browser to not respond. And then normally one could move the mouse cursor around and go to another window or go to Task Manager and force quit the Firefox Portable exe. But I can't even do that, because the entire laptop will freeze forcing me to force shutdown and restart the laptop. I'm exasperated. I use Firefox Portable more than other program. I can't keep dealing with this. I'll probably try to do a fresh install later (even though I just did one like a week ago). Just really disappointed.
