My up-to-date Firefox refuses to open the Coursera website, though everything else opens perfectly. The link is www.coursera.org. The site opens in Chrome.

Được đăng

My Firefox used to have no problems earlier with opening this website. However, since the last two updates, it will just not open the site. I can see the Coursera logo spinning in circles for ever, but the page does not open.

There is no other problem. I tried emptying the cache already.

I am using a Windows 8.1 OS on a Dell laptop that is just over a year old. There are no memory issues, no viruses, no firewall-issues. So where is the problem? My Flash and other plugins are up-to-date and working just fine.

Dear Jayakumar,

My offline cache has 0 bytes, and therefore nothing to clear.

I removed the individual cookies related to coursera, but it still does not load.

The reload does not work.

Thank you for your effort.

Dear Fred,

Thank you. I had no toolbars, but the only recent app I had downloaded - a program, actually, was Dragon Naturally Speaking - and this program had installed a plugin on Firefox to enable speech recognition on different websites. I also had an avast plugin on my FF. I decided to first disable Dragon plugin. I also deleted Coursera from the History as you had suggested. Then, I re-attempted the opening of the site, and voila! It opened as it used to, earlier.

So the Dragon Plugin was the culprit.

Thank you for the input.

You should be able to install Dragon plugin, and disable it for Coursera.

Go to the web page. Once the page is loading, mouse to the address bar and Left click the icon. A window for displaying site information should come up. Select More Information. Now select Permissions. In the menu, find the plugin, and set it to Never or Ask. This action will only effect that one site.
