Mozilla add this to Firefox Rated 5 out of 5 stars
I just used this extension and really believe that it should be in the next Firefox as a standard feature. It probably won't be in the next Firefox so can you please update it to be compatible when the new version comes out. Firefox 4 does have a feature of showing you if the tab is open while you type in the address bar but you need to type while deleting the old URL or in a new tab. Your approach is much better.
What if you add a feature to open new tabs if the text doesn't match anything available.
You don't seem to mention that ' alone without Ctrl searches URLs of open pages and not titles.
