The Firefox add-on is preventing a website to refresh.

The website is www.metro.net/riding/nextrip/

It refreshes for a while and then stops. After disabling the add-on, I have no problem with this page.

This has nothing to do with Myibidder add-on which works on eBay website only.
I uninstalled the add-on and the website loaded and the small portion refreshes.
I then installed the add-on back and the same thing -- the website just loaded and the small portion on the bottom refreshes.
Do I need to wait hours for it to stop? I definitely did not wait that long. I waited about 10 minutes or so.

Try to disable all add-ons and enable them one by one to see which one is causing it.

It's been 30 minutes of refreshing with no problems while add-on is installed.
