Worth It Rated 4 out of 5 stars

Results aren't always relevant, but it makes it very convenient for pulling up webpages related to browsing activity.

Should be default Rated 4 out of 5 stars

Should be a default feature in upcoming Firefox builds.

Interesting at first, but annoying after a while Rated 1 out of 5 stars

I've tested this since it was introduced. My opinion is that this doesn't make the search in the location bar faster than the standard solution. The fact that it completes the word automatically makes the location show a lot of pages that share the same word, which most of the time are related. So if I press a letter it displays a list of related pages, because their title contains the auto-completed word, instead of showing me the most 'frecent' pages starting with that letter, which I consider to be more helpful.

This is a serious issue. When you type something the first suggestion is selected. But now if you move the cursor around and hit the delete button history links are deleted and not characters from the typed word.

Sorry about that! It should be fixed in v6.

Not very interesting Rated 2 out of 5 stars

This add-on is inconvenient with the instant preview add-on: the page is refreshed at every new typed letter !
It would far more useful if the engine results (google.com, google.fr ... Bing, Yahoo or else) were included the history results

Great Add-On. Should be standard functionality for Firefox. Because, imo, the standard auto-fill is somewhat broken and not implemented too well.

I find it really useful for visiting sites websites you already visited, but for searching in the location bar, which I do a lot, it's a pain. This flaw makes it a no go for me.

You can force the location bar to do a search by pressing "right," which will deselect the item from the suggestions. Do you have any suggestions for how to better support searching?

simple yet powerful Rated 5 out of 5 stars

i know i said this already but now that i've used it for some time i can confirm that this extension is soo much wonderful! it definitely needs to be implemented in ff4!! (along with instant preview and find suggest) not only it fills the remaining letters and words but it also auto selects the first result! this makes for a perfect combo with instant preview ...well, needless to say, as long as the user can toggle this function at will from the preferences:-)

This addon is really useful, and lightening fast. One can open a tab, often hit only one letter and then have the address you wanted ready.

I only wish it was included by default in the 4.0 betas

Much needed Rated 4 out of 5 stars

This is great but it seems to break searching by keyword.

Super Add on Rated 5 out of 5 stars

Funktioniert von Anfang an perfekt. Will nicht mehr ohne.
Sehr geil ist auch das es schon auf Jetpack basiert und man den Browser nicht neustarten muss.

Works good. Will it also auto-complete the user defined tag and phases from page title? (It should be!)

Thanks for the suggestion. I've filed an issue for you to have tags and keywords suggested:

Nice one (and finally)!!!

Better than Google Chrome's auto fill function! And works seamlessly with the "Switch to tab" function.
