If this page opened automatically for you, then your add-on Location Bar Enhancer has been updated to the latest version 4.7 and this page will not be opened automatically again. If you came on this page yourself, then you can try the latest version from here.
Version 4.7 contains many improvements, both on the front-end and on the back-end. On the front-end, the major change is the compatibility fixes for Mac users. I was having many complaints about visual glitches caused by my add-on on Mac OS X, but I was unable to fix them as I did not have any Mac to test the add-on. It was Fabrizio La Rosa, who came forward for help and fixed the visual glitches related to the height of Location Bar as you can see in the images below:
He also fixed the margin issues of the Bookmarks Enhancer part of the add-on.
Another important front-end fix was the compatibility with the browser preference instantApply. This means that on Mac and Linux, the Options window will not close directly after any options change as it used to do before. (The same will happen on any OS or Firefox version if you have the preference
browser.preferences.instantApply set to true.
Thanks for using my add-on and I hope to make it more and more useful on every update.
Spoiler: I am working on a new theme which would be in sync with the new Identity Box design in Firefox 15. I will try to finish it by version 5.0 .
