Problem opening some sites through firefox

It happens when the site server is very busy and internet connection is very slow.. I use Firefox and IE but loved Firefox more because most of the plugins and add ons add up without disturbing. For suppose if a site need a flash pugin then Firefox adds this plugin automatically without disturbing us.. General when server of particular site is busy then those errors appear. Sometimes site will maintainance happens then also it might happen.

Some sites are designed with keeping in mind the Internet explorer which is the pioneer.Those sites uses all the specific things with IE which may not be available with other browsers.It is so because IE is the default browser you get with OS and so it is inevitable.I face the same problem with some government sites,They work well with IE and with firefox,some details will be missing or scrambled.

Can you share the link? If you can open it in IE and chrome then firefox appear to be the one that has the problem. Maybe its one of your addon that preventing it to be accessed properly like noscript, a cookie monitoring addon or something.
