3.2 is what I need exactly which makes itself smarter.
Better if let user define hotkey(like TAB) to navigate the search results

This review is for a previous version of the add-on (3.2). 

Hi, I am extremely sorry that I forgot your request. That is why I have been telling you to open an issue on Github page. Please do it otherwise I might forget again for the next version.

I think adding a Tab key is enough. Of course, giving a choice of customization is best.

This review is for a previous version of the add-on (3.1). 

Please do not re-review again and again :P
Use the github page http://github.com/scrapmac/Auto-Complete for discussions etc.
I considered a preference because some people might want to have tab to complete feature.

Hey,what about adding a TAB key to navigate the popup results in addition to the existing up/down/hover behavior?

This review is for a previous version of the add-on (3.1). 

Sure, may be a preference to control the behavior ?

I enter them and press ENTER,but nothing happens. And about:config will be loaded from google search as a instant preview.

This review is for a previous version of the add-on (3.0). 

Thanks for the screenshots, I found the issue, it seems that the instant preview everything is conflicting. If you turn that off, you will be easily able to go to any about page.
I'll fix this in the next release within hours..

Thanks Rated 4 out of 5 stars

tested in FF12a2(auto complete 3.0)
I stille have to press escape before opening about:config to bypass the matching results.

the global on/off option seems useless since enable/disable add-on needn't restart. We could consider this as a global switch.

This review is for a previous version of the add-on (3.0). 

The global On/Off only toggles the auto complete part, leaving the instant preview part in tact.
What is your first matching result by the way?
Can you send me a screen shot ?

I hope the next version will be localized into other language, eg. en-US or more.

This review is for a previous version of the add-on (2.3).
