Firefox automatically minimizes itself

[mangaman]

After installing the official 64 bit Firefox browser from Mozilla's website, the 64 bit version is acting very strangely. When watching YouTube, the window that I am on will suddenly minimize or hide behind other open windows. Also, if I have an open Firefox window behind another Firefox window, the window behind it will sometimes move in front. I never had this problem in the 32 bit version of Firefox, and the only reason why I downloaded the 64 bit version is better browser performance.

I did an anitmalware/anitvirus scan and nothing came up. And yes, my system is 64 bit with 8Gb of RAM. So, what is going on?

Edit: thumbnail previews are also not showing up, if the 64 bit version is maximized. The 32 bit version does not have this problem.

If you are using Firefox then I suggest you check the settings in Options > Under the "Tabs" Tab. Try it with all of them checked.

I would reinstall it and see if the same thing persists, it might just have been a bad install. Make sure you got Firefox Setup Stub 53.0. Let us know if that resolves it.

So it seems everything is working fine on the 64 bit version, ever since I reinstalled and used the recommended options. I will use it for a few more days to see if the problem persists, then report back on my progress.

Update: The 64 bit version is working fine, ever since I reinstalled and did the recommended settings. Might have been a bad install after all. Though it still has some small bugs, but nothing too major. 99Hacks link for the stable install, was very helpful.
