I've had the issue happen to me a few times but from what I've gathered there are quite a few things that can set it off.
- Clear your browser cache, cookies, etc just to be sure.
It most likely will not fix the problem permanently or even temporarily.
- It could be an issue with gzip.
Open a new tab and enter the following " about:config " then you'll see a warning to be careful just confirm it.
In the search bar enter " network.http.accept-encoding "Make sure its value is " gzip, deflate " if not right click it and click the option to reset.
Some people report changing it to " true " can fix the problem but I would not recommend it since it's most likely going to cause more problems down the road.
- Check your firewall especially if you're using Zone Alarm.
Removing all the added programs and resetting the defaults actually fixed it the first time for me.
- Clear your ssl slate by going into your control panel then clicking internet options.
Once open click the content tab and click clear ssl slate.
- Are you using a custom DNS? IE OpenNic if so turn it off to make sure.
If you don't know what I'm talking about ignore this.
- Run a good privacy cleaning program like Advanced System Care or whatever you use to do that.
The last time it happened to me I did all of the following followed by a reboot.
I've not had the issue again in any browser and it's been a good while now.
Hope this helps you.
