Since we updated our version of Firefox we're not getting the security padlock symbol when we want to buy items online.
When using sites for shopping the padlock symbol no longer appears at the bottom right of the screen when card details are being entered. This has caused us to withdraw from transactions because we are not convinced that they are secure. The problem has only arisen since we updated Firefox a few weeks ago. The sites we are using are large reputable companies we have used before - we have contacted them by phone and been told that the transaction should have been secure but we had no visual proof.

As of Firefox 4, over 6 months ago, the Statusbar is gone and the "lock" with it. Security information about a web page is shown by the Site Identity Button.
The old padlock could give users a false sense that a site is secure by not supplying all of the information about a site and only showed that there is a secure connection that didn't guarantee that you are connected to the right server. The Site Identity Button was introduced in Firefox 3.0 to show more complete "identity" information for HTTPS web pages.

You can add a padlock to the location bar with the Padlock add-on- https://addons.mozilla.org/firefox/addon/padlock-icon
