So some of website are reloading every few second. First i notice that on Yahoo Finance and i though it depends from website, but now it is happening also on eBay websites so it must be something else. How does it looks? The uploading icon in the tab on the left side, is starting to circle every few second ( every 5 or 10) like is loading page. But page doesn't reload again, I dont see any changes on the site in this process. Maybe is reloading adds or something, And that reload circle is spinning just a second or 2. So- 5s normal-2s spining-5s normal-,... Anyway i was reading a lot, but I cant find any answer for this. I tried open in safe mode and I tried with disabling hardware acceleration. Doesn't help. And in Chrome I dont have this problem. I also just updated Firefox and updated graphic card driver from there website (quadro 600). I have windows 10. Problem is that the browsing is now very slow if i have this multiple tabs open and it is even starts lagging and freezing's for a second.
