While working fine for few hours suddenly it begins some sort of activities consuming up to 70% of processors time making Fox practically unusable for hour or so. If closed and restored it works fine for a while and this same thing starts over again.

The Fox starts OK, works for some time and then something begins running internally so it consumes almost all available resources, and not only Fox becomes unusable but it slows down the whole computer. When I shut it down and restore than it come back to live like nothing happened. And this process begins again after some time. It stops on its one after an hour or so. I found few pluggins causing problems but this issues remains.

I have good firewall and run ESET NOD32 and so far they didn't let anything dangerous, I think

It's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in safe mode (don't forget to select Disable all add-ons when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See this article for information about troubleshooting extensions and themes and this one for plugins.

If you need support for one of your add-ons, you'll have to contact its author.

If the problem does not disappear when all add-ons are disabled, please tell me, so we can work from there. Please have no fear of following my instructions to the line, as all can be easily undone.

That might have something to do with the Plugin-container.exe. Please read this thread and try the solutions that AliceWyman suggests to see if it helps:
