This extension works for all text fields, but doesn't work in a form that contains more than one date selector (Example: buying tickets for 4 people that requires each birth dates). All the date selectors will autofill the last person's date of birth.

this helps you when certain websites do NOT let you save your forms !! typing everything again is a HUGE pain. This extension lets you memorize information and activate it on the desired websites !
One issue I did confirm is that when creating a rule...on various websites the extension does not do it right... It forgets one or two forms...solution is to enter settings and force it manually.

dose not support utf-8 languages for exporting

Firstly great extension thank you. One thing that would be good is if left clicking the extension icon in toolbar filled in a default profile on the page. Right click page -> Autofill -> Execute profile -> [Profile name] each time takes a bit of time. I have turned off auto-fill as job is in web development and I don't want my address, card number etc. being filled in when I'm testing websites, especially when demoing to other people. Overall amazing extension though, thank you very much (have just rated 4 star because of issue above).

For anyone struggling to get started/thinking it doesn't work: Right click on extension icon in toolbar -> Manage Extension -> will take you to about:addons for Autofill (this extension). Click on Three Dots drop down -> Options. When on this page try adding a new field using values: Type: 'Text', Name: 'Email', Value: [your-email-address]. Go to a checkout page and check that it auto completes for you. You can continue from here by adding fields like 'First Name', 'Last Name', 'City', 'Country', 'Phone' etc. . Learning regex might be helpful here. One useful tip for this extension if don't know regex: use pipe | to match multiple cases e.g. 'Last Name|Surname'. Seems like lots of the 1 star reviews are from people who couldn't find this settings page though, but hopefully instructions above are helpful for these people. For any pages where your manual rules don't work: Right click on page -> Autofill -> Add rules for this page/field -> After filled in -> Generate Autofill Rules. Judging by the screenshots on this extension's home page 'Generate rules for this page' is the behaviour left clicking the extension icon is supposed to trigger but as other reviewers have said left clicking the icon does nothing.

I mod in a chat room and this extension made my life a lot easier. Use to love it, cause it stopped working yesterday. Can't find a fix for it.

best form filler for Firefox. far more difficult than Chrome.. simple fill in of address requires tons of duplicit records.. this functionality, together with easy page translate and tab to search, is the highlight of Chrome. Wish Firefox added any productivity features, years go by...
I hate how difficult is it to reach the options of this addon.
