About Fill it Up!

FillitUp! allows you to automate the repetitive entering of form fields. Just save your current fields and have them automatically fill next time you visit that page. Features: - Supports standard form fields such as INPUTs, SELECTs, TEXTAREAs and content editable DIVs - Supports Google Forms - Supports Microsoft Forms - Supports running of custom JavaScript routines to fill those pesky non-standard fields - Automatically save all your fields with the click of a button, or optionally decide which fields to save - Automatically fill fields on page load, or optionally manually fill at the click of a button - Logically group your saved fields and optionally only fill fields in that group - JavaScript editor window to create custom JavaScript routines with the option to immediate test them - Special filters to allow you to change the default behavior of FillitUp! for those extra stubborn websites - Option to fill fields discovered by the Mutation Observer or by querySelector(). Even fill automatically using one, and manually with the other. - Options to Export and Import your entire FillitUp! environment to ensure you never lose your hard entered work. - Already tested on thousands of websites by a sweepstakes addict. I wrote it for my own personal use, and decided to make it available to anyone who wants to try it out. - Open it Up! and Fill it Up! work hand-in-hand to automate the process of opening lists of URLs and filling in the fields. Oh yeah, it's free! Caveats: - This is NOT a username/password saver. All saved fields are in clear text, so don't use it for that. - This extension has been written for English language websites. It's been minimally tested on non-English sites. Your mileage may vary. - This extension will NOT automatically fill a form on the first visit to a website. Entries must be saved and will be filled on subsequent visits. - There are a few configuration popups in the settings page. If you have a popup blocker, you might have to adjust its settings. - This extension is NOT designed to fill CAPTCHAs. On initial installation, automatic filling is turned ON in QS mode by default and can be changed in Options->Settings. The developer uses these settings for all sites: - Enable Rule Logging - Display Hidden Fields - Display Floating 'Apply Rules' Button - Automatically Apply Rules (querySelector) - Manual Apply Rules Mode (querySelector) - Match REGEX - Run querySelector in MAIN world - Use URL Hostname/pathname - Master Delay (milliseconds) 750 - Fill Delay (milliseconds) 125 - Global Hotkey ctrl+z - Use OS Default Theme - Use userScripts.execute Comments to: fillitupextension@gmail.com
