How do I turn on video preview?

In selecting a video to open, I used to be able to preview videos. Now, previews will not open.

If the previews are part of a website, could you provide a link to the page that isn't working correctly? Also, I will paste some general suggestions below.

If the previews were part of a video download list, do you know which add-on it is? Some of them may need to be updated for Firefox 26 and late due to the changes in the way downloads are listed.


When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.

(1) Bypass Firefox's Cache

Use Ctrl+Shift+r to reload the page fresh from the server.

Alternately, you also can clear Firefox's cache completely using:

"3-bar" menu button (or Tools menu) > Options > Advanced

On the Network mini-tab > Cached Web Content : "Clear Now"

If you have a large hard drive, this might take a few minutes.

(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:

  • right-click and choose View Page Info > Security > "View Cookies"
  • Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"

In the dialog that opens, you can remove the site's cookies individually.

Then try reloading the page. Does that help?
