Update is a big mistake Rated 5 out of 5 stars
This version 1.5 is a downgrade! Ed removed the 1.4 improvement: There is now an option to highlight the URL or dump the focus on the page loaded. Many webpages do something smart with the focus. (google included)
That was the only advantage against any other new tab extension, or the built-in <a class="linkification-ext" href="about:config" title="Linkification: about:config">about:config</a> solution. So everybody go back to 1.4, it's perfectly working in FF13.
"I will fix this." Ok, thank you for your work! We can't live without this :D
I will fix this. Unfortunately I won't be able to until late next week as I will be traveling. Version 1.4 does not work in ff 13 for me but if it does for you guys than that's great. If you can't live without this feature I suggest using 1.4 on ff12 until late next week when I update :)
UPDATE : New version up now (1.6), waiting for review from Mozilla.
SECOND UPDATE : 1.6.x is up and reviewed. Has all features requested (focus placed in google search or URL highlighted in address bar)
