Firefox Inline Autocomplete

Memo to myself:

To turn on inline autocomplete in the Firefox web browser…

  1. Enter about:config in the URL field
  2. Right-click on the page and create a new Boolean value
  3. Enter browser.urlbar.autoFill as the preference name (note, case-sensitive: ‘F’, not ‘f’)
  4. Set the value to true

There. Maybe next time I won’t have to Google for it again.

    Thank you for this boolean instruction. It was annoying that the great Firefox didn’t have this feature. I can’t believe I didn’t do a Google search until now to try and add it.

  10. Justin says:

    Oh man… Just like someone else said: inline autocomplete was the ONLY thing I was missing from IE. Missing so much that I actually was going to stick with IE because of the time, typing, and clicking it saved me. Not anymore. Thanks dude!

  11. Jerry Matson says:

    How do I delete items from my auto complete lists? Lists are getting too long.

  12. Jimmy says:

    Are we talking about autocomplete in web fields e.g. search boxes, address fields, etc.? I also would like to delete. In IE you can arrow down and just hit delete.

  13. Jimmy says:

    I solved my own question–it’s SHIFT + DELETE. Now I can delete all my porn searches. This site is helpful.

  14. Jerry Matson says:

    Jimmy, you’re a genius! Thanks for the url. Shift + Delete solved my biggest problem with FireFox.

    Geez, that’s the reason why I stick with Mozilla, because a lot of simple but yet very usefull functions are not enabled in Firefox by default. I also think it’s ridiculous that you can not enable them besides using the cryptic about:config interface. Even in Mozilla a user can easily enable or disable autocomplete in the preferences.

  18. Brad says:

    It important to note here that you social security number will be stored if you use it for logging in somewhere. Unless you internet banking-provider or whatever has included an “autocomplete = “off” -tag in the htm-code.

    In other words, to prevent identity theft, autocomplete should be used with care.


  19. Sir says:

    Where are all the Firefox autofills saved? I know how to delete autofills from IE5 in one go, but want to know how before enabling FF.

  20. Remus says:

    And how do you turn this off ?
    It would be logic if you set browser.urlbar.autoFill to false, but that isn’t working here ?!
    Any tips ?

  21. swiss tony says:

    how do you turn that damn thing off!

  23. Val says:

    Whow that’s just perfect, exactly what I was looking for. Thanks

  24. Danny says:

    >>>>>>>>>>>>>>>i figured this out myself. if you want to get rid of form fill, for things such as google searches (not for the url bar), then you need to:

    type into your url bar: about:config
    then, type in the filter bar: browser.formfill.enable
    now, double click it so the the boolean value is false

    i did this with Firefox, i’m not sure if the same will work for other browsers

  25. munkysurf says:

    This “fix” only does autofill during the same browser session. Once I close Firefox, and reopen it later, nothing autofills. Anyone having this problem?

  26. Dougal says:

    It works fine for me across browser sessions. Maybe you have some other setting that’s causing a side-effect? Maybe you have Firefox set to not save your browsing history?

    Is there anyway to enable the dropdown history list while preventing it from opening automatically? That is, you could type in your URL without seeing the history, but if you needed it, you could click on the dropdown history button and see the possible completions?

  30. Couf says:

    I`ve tried to set Autocomplete to TRUE, but nothing changes? Enter about:config, then add browser.urlbar.autoFill, then set to True. Any idea why this won`t work? Thanks.

  31. RG says:

    I’ve been trying to figure out how to do this. Yours is the first site that was right on. Thanks!

  32. Sean says:

    Is it possible to have it go to the root domain first, then the subdomains? Having it autocomplete something obscure doesn’t save time…am I doing something wrong or is that coming?

  35. voide says:

    thanks man, lol, i used this for the reverse, the autofill was pissing me off but i couldnt figure out how to turn it off.

  36. bismarck says:

    Any of you knows where can I get a trick that I can use for this in firefox 2?

  37. Jim says:

    Thanks much. I just added this to FireFox 2 and it works fine.

    How do you turn OFF the autofill in FireFox? I find it very annoying that everytime I type a number it gives me 25 choices to select from when I all I want is that one number.

  40. Harmony says:

    Can somebody PLEASE tell me how to turn off this incredibly annoying feature. I have set everything I can find in about:config to false including the items mentioned here. I’m using Firefox 2. If I can’t get rid of this feature I am giving up on Firefox. It is *that* annoying to me. A feature that gets in my way is more annoying than three I want but don’t have because I *hate* software doing what I don’t want it to do.

  41. Harmony says:

    To anyone else who googled in here looking for ways to turn off the autofill in the google toolbar in Firefox 2.x. It turns out to be very simple. Right click on the tool bar (or context thingy on a Mac) and untick show suggestions. Not that you’d ever know that without trying it, of course.

  42. Jack says:

    Just a quick note to say thanks for the info on the inline autocomplete, I have been meaning to sort that out for ages and thanks to you it is now working fine.

  43. Chris says:

    Thanks, very much appreciated. I was thinking of going back to IE since it was so annoying.

    Why the inline autocomplete do not work for
    Really!! Try it! Do not works!!
    (sorry for the bad english, i’m brazilian)

  46. Gromit says:

    Awesome, no idea why this isn’t the default setting.

  47. maryp says:

    I can’t get this to work with either. It’s worked in previous versions of Firefox–could Google have changed something to prevent the autocomplete, perhaps in order to boost gmail (since that’s what I get if I just hit g)?


  48. Tyghus says:

    Thanks. I can finally start using Firefox as my main browser as this was the one thing that really was really missing for me.

  49. Glen says:

    This works for Mac as well – Inline Autocomlete for Firefox Mac Version… Thanks you so much for this!

  50. Derby says:

    For those who changed urlbar.autoFill to true but still don’t see anything: make sure that urlbar.maxRichResults is not set to 0. (The default is 12, which you get by right-clicking on the setting and choosing ‘reset’).

  51. Byoon says:

    Thanks a lot, this helped me quite a bit during my searches.

  52. ben says:

    nice, thanks a lot for that. veryy useful
