Firefox is slow in Ubuntu?

It's probably working OK for you, but not for me. I've seen Firefox as awesome, in Windows -- could not bear slow Internet for millions of pages I browse everyday. So, I googled around and there were way too much confusion but most of them were pointing directly or indirectly that the culprit is IPv6 . I have found a easier fix (somewhere on the Internet).

Here is what you should do.

1. Open Firefox and type
   

   about:config

   in address bar, hit enter.
2. Scroll down until you see a line like this
   

   network.dns.disableIPv6 = false

   
   
3. Double click on this line so that it becomes
   

   network.dns.disableIPv6 = true
   

Now, try opening a new web-page. You should see the status-bar, it is connecting to the website quite quickly.

PS: This is the solution that worked on my machine. There might be other issues related to network that might cause page load latency. This is just one of the solutions.
