How to turn off Firefox autocomplete for only certain websites, or for all sites temporarily?

Question

I want to turn off Firefox autocomplete, but only for specific websites--not for the entire interwebs. My language course has an online workbook, and the autocomplete keeps giving me the answers if I need to re-do an exercise. The tutorials I've found online all tell me to clear out my form history. I don't want to do this. I just want autocomplete to not work for a specific set of websites, or alternately turn it off temporarily. How can I do this?

Answer 1

The Form History Control extension for Firefox allows you to clear the AutoComplete storage for specific websites, and supports many other advanced AutoComplete tasks.

Answer 2

1. Go to my JSFiddle example.

2. In the bottom right corner there is a link with the text ACOff.

3. Drag this link to your bookmark toolbar.

Now go to your website - click the link, and all fields with type=text have their autocomplete turned off.
