FullForms Firefox

FullForms

Search your glossaries and look up abbreviations on FullForms.com from the address bar, right-click, or side panel.

Features & Capabilities

FullForms brings your glossaries and abbreviation lookups right into Firefox. Search your FullForms lists from the address bar, the right-click menu, or a sidebar, and add new entries without leaving the page. FullForms.com lookups work even without an account.

What you can do

  • Address-bar search: type fullforms, a space, then your query, and pick a result straight from the suggestions.
  • Sidebar search: open the FullForms sidebar to search your lists and favorites, star entries, and quick-add new ones.
  • Right-click any selected text to search it in your lists, look it up on FullForms.com, or add it as a new entry.
  • Quick-add entries with definitions, types, tags, and rich descriptions (mentions, callouts, and more) without opening the website.
  • Offline search: your lists are cached on this device, so lookups keep working when you lose connection.

Sign in once Sign in with the same account you use at list.fullforms.com. A token is minted for this device under the hood (you never copy or paste anything) and you can revoke it anytime from your account page. Public FullForms.com lookups work without signing in.

Using it on Firefox

  • The sidebar opens on the left. Use the sidebar toolbar button, or View > Sidebar > FullForms, or the keyboard shortcut.
  • To set or change keyboard shortcuts, open about:addons, click the gear, and choose Manage Extension Shortcuts.

Your privacy The extension talks only to list.fullforms.com to search your lists, add entries you create, and sign you in. It sends no analytics or telemetry anywhere. See the privacy policy.

Is FullForms Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

FullForms requires very minimum permissions.

Risk impact analysis details
  • Low Allows usage of omnibox input, negligible risk as it pertains largely to user input enhancements.
  • Low ******* ****** ** *** ********* ******** *************
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

FullForms is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
