Thank you for trying the new Firefox. I'm sorry that you’re unhappy with the new design. Firefox is a work in progress and your feedback is very important to us. Our support community is run by volunteers (like me) who work hard to help all Firefox users, but we can’t make changes to the design ourselves. Please help us improve Firefox by leaving feedback where the designers and engineers can see it: https://input.mozilla.org/en-US/feedback. The interface you see in Firefox 29 is a major re-design (first one since Firefox 4) of Firefox's user interface called "Australis." Here are a few suggestions for restoring the old design. I hope you’ll find one that works for you: *Use the [https://addons.mozilla.org/en-US/firefox/addon/classicthemerestorer/ Classic Theme Restorer] to bring back the old design. Learn more here: [[How to make the new Firefox look like the old Firefox]] *Use the [https://addons.mozilla.org/en-US/firefox/addon/the-addon-bar/ Add-on Bar Restored] to bring back the add-on bar. Learn more here: [[What happened to the Add-on Bar?]] Or if you want to go back to a previous version, completely feel free to use the old, unsupported, and insecure versions of Firefox. Please remember that this puts your machine and personal data at an increased risk. You may then wish to mitigate that by having well rehearsed bare metal restore strategies or using a virtual machine. * See also [[Install an older version of Firefox]] <i>Note:</i>I won't provide a link to any previous versions since I'd be offering a less secure and outdated version of Firefox, however, the previous versions are available for download by doing a quick Google search or by simply visiting the link above titled Install an older version of Firefox. Please remember to be wary of what sites you download from as they may advertise Firefox 22 for example and package it as a Beta, RC, or other pre-release version and may have malware/adware or other unwanted items.
