Hello Tammy. Although possibly not related to your problem, I will remind you that the version of Firefox you are using at the moment has been discontinued and is no longer supported. Furthermore, it has known bugs and security problems. I urge you to update to the latest version of Firefox, for maximum stability, performance, security and usability. You can get it for free, as always, at [http://www.getfirefox.com getfirefox.com]. As for your issue, this may be a problem with the toolbar you are trying to install. You need to contact the toolbar's author for support. Unless you can't install any extension at all. Is that the case?
