How can I set FF to start typing ahead? Such as if I'm at a Web Site that needs my personal info, I put in the first letter of my email and FF puts the rest?

How can I set Firefox to start typing ahead? Such as if I'm at a Web Site that needs my personal info, I put in the first letter of my email address and Firefox puts in the rest of the letters? IE has set up this. It just makes it so much easier typing in personal information.

Firefox has a rudimentary "form fill" or "autocomplete" feature, which is tied to form and search history.

Users have to be careful if they Clear Recent History that they deselect Form & Search History; that data is saved in its own cache and not saved in a data file.


As Fred mentioned, using an "auto-fill" extension is preferred by many users. That type of extension allows the user to set up their personal data, and then have that information "auto-fill" as needed in webpage "forms".

Currently, the most popular "auto-fill" extension seems to have disappeared from Addons,Mozilla.Org website within the last day or two. I had seen a number of support threads about a compatibility issue in Firefox 50 with that extension; and I suspect the developer pulled it from the AMO website. Not sure if that developer is going to fix the compatibility issue (probably multi-process related), or is writing a new extension in the new WebExtensions format, or he is just giving up with his "auto-fill" extension. I saw it listed at AMO on Tuesday; today it's gone.

Personally, I have little use for that type of extension, but I did use and provide development suggestions (aka critique what they were doing, fro the view of a "long term user") for an "auto-fill" extension back in 2004 during the lead-up to the release of Firefox 1.0. Those developers had created what I would call a "state of the art" add-on, but ran into silly compatibility issues every week due to Mozilla. And by the time Firefox 1.5 came out 6 months later, and 1.5 required changes to that extension, those developers just gave up; and "we" lost that particular extension. After using the "ultimate auto-fill" extension I did try a few others, but they failed by comparison; and since my need wasn't great I have just stuck with the default "autocomplete" feature.

It's a real shame that Mozilla hasn't seen fit to expand these basic "autocomplete" features in the last 10 years; but hey, that's software development! Re-do the User Interface repeatedly and ignore basic features; that looks better on a resume' than the "scut work" that few potential employers will appreciate.

You would be better off using a form-filling add-on. The can be set up on a per-site or global entries like name, address . . . . .

Go to the Mozilla Add-ons Web Page {web link} (There’s a lot of good stuff here) and search for what you want.
