Certain websites cause Firefox to stop loading anything

Ever since 6, I've experienced an issue where Firefox would not completely load certain websites. The bigger problem is that when this occurs, Firefox suddenly refuses to load anything. The only fix I've found is to restart the browser. When this happens, CPU usage goes higher than usual, and, oddly, my laptop's core temperature rises by up to around 20 degrees Celsius. I've tried safe mode. This problem only happens in Firefox. It has gotten worse since updating to 7. I seem to run into a random site that triggers the problem like every 10 minutes.

And now it's crapping out seemingly at random too.

The default of the pref network.http.max-connections has been increased from 30 to 256.

You can try to decrease the value of the pref network.http.max-connections from 255 to a more modest setting of 30 as used in Firefox 3 versions.

To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.

  • Use the Filter bar at to top of the about:config page to locate a preference more easily.
  • Preferences that have been modified show as bold (user set).
  • Preferences can be reset to the default via the right-click context menu if they are user set
  • Preferences can be changed via the right-click context menu: Modify (String or Integer) or Toggle (Boolean)

Thanks. That fixed it and also sped up Firefox a bit I think. I figured it had been something in there but I didn't suspect a default preference would be the cause.

You're welcome
