my facebook page having a lot of lags

[q12x]

my current FF version is : 52.0.1 (32-bit)
I must complain about this problem, I waited a couple of weeks, maybe it will get to normal, but it didnt. I witnessed 2 FF auto-updates in last 2 months. And until these updates, my facebook page was working, acceptable somewhat. But now is working with a lot of lags, a lot, and is slower than usual.

I admit I dont have the best one, it could be because of my hardware...
My computer specifications:
Microsoft Windows 7 Ultimate
Processor Intel(R) Core(TM)2 Quad CPU Q9300 @ 2.50GHz, 2499 Mhz, 4
Installed Physical Memory (RAM) 6.00 GB (with 4GB*2)

What are your thoughts?
It is because my hardware? And why it was working relatively fine before the updates, and after it just bugged down? I hope you can make an update to help the small hardware ones like me, too.
I promise in some years I will update my hardware...
Thank you!

No updates from us... we are just users helping users.

...and as GHM113 eluded to... you can reboot your PC into safe-mode with Network active and then test out your problem... that mode will disable your AV software... so, remember that.

No. AntiMalware and is not active. I open it when the troubles appear.

Ok, sorry, but do transmit to the people responsible if you have the knowledge of them. I dont think I am the only one with this problem. It will help others too.
Thank you.

That test could tell you something.
