Try running Firefox in Diagnose Firefox issues using Troubleshoot Mode. If it functions properly in that configuration, then one of your add-ons is the culprit.

Thanks!

I have tried Firefox to run in safe mode but not getting positive result.

My website contain an article page having paging in to that. In article I have reserve a space for normal image or google ads.First page is display correctly and that have no ads but when I have tried to click on 2 or 3 page, Firefox displays white page with "Stopped" message in status bar.

Could you please do the following. In the location bar, type: about:config and hit Enter. In the filter which appears next, copy/paste the following: network.dns.disableIPv6

Double click it to change it from False to True.

Then close about:config and see if the problem recurs.

If it does, could you give me a few links where the problem occurs?
