Context Lookups Firefox

Context Lookups

This extension adds configurable lookup options for the context menu of selected text.

Features & Capabilities

Quickly search information as you browse. Just select the text you want to look up, bring up the right-click/long-press context menu, and select the configured lookup option that you want.

Need to quickly check the definition of "bi-weekly" when someone emails you about a meeting? Curious about the literal meaning of "je ne sais quoi" when it comes up in an article? Want to know who exactly "Robert Walpole" is when someone mentions them in a comment?

Context Lookups has you covered! Get up to speed or satisfy your curiosity in no time at all, then be on your merry way. You can set the results to appear as regular webpages, or make things extra convenient with simplified popup windows.

This much can already be done with just the default lookups, but the possibilities go far beyond that. Copy the search query URL base of whatever website you want to use, and create a context menu item for it in the extension popup, it's that simple. Just remember to save your changes!

Here are a few more to try:

Unit Conversion

Synonyms/Antonyms

Rhymes

Note that ampersand characters (&) in context menu labels are used to assign shortcut keys. To make a letter within the label the shortcut key for the option (while it's shown), simply put an ampersand in front of it. For example, set the label as "Rh&ymes" to make a context menu option "Rhymes" with the shortcut key 'y'. To put an ampersand in the actual label, simply include it twice, as in "Synonyms && Antonyms" to get a label of "Synonyms & Antonyms".

This is my first extension, so any feedback is appreciated.

NOTE: Due to browser limitations, results displayed in a popup are unfortunately restricted to the primary display. If using multiple displays, try to keep the browser window using the extension on the primary display. Alternatively, you can set the results to display as normal pages instead.

Version 2: Now supports parent menus!

Version 3: Updated to use Manifest version 3. Apologies for any resultant issues I might have missed. After a couple revisions, I think I've got it working with pre-existing saved data, but if you still encounter issues, I recommend saving your loaded configurations from the extension popup to update the saved data.

Opening as a regular window popup is now supported, by simply selecting the center of the slider.

Changed the default definition lookup to a simple Google search query, as this has better fallback behavior when a definition isn't found in the primary source.

Version 4: New features and quality of life improvements:

  • Import and Export from/to a file (remember to save after importing!).
  • A much larger number of menu items are supported than before (working around browser limitations).
  • Internal scrolling, for retaining easy access to button controls.
  • Now indicates when you have unsaved changes.
  • Encountered errors now get displayed, though hopefully this won't be needed. :)

Added a link to my portfolio site with my other projects.

Version 5:

  • Now available for multiple browsers!
  • Various updates and improvements.
  • Better accessibility support.
  • Dark mode, applied in accordance with the browser theme.
  • Updated the default translation lookup to work with the latest Google Translate URL structure.
  • You can now do configurations in an options page rather than the extension popup (necessary for importing data in Firefox since it automatically closes the popup when the file selection window is shown).

Is Context Lookups 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.

Context Lookups does not require any sensitive permissions.

Risk impact analysis details
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.

Context Lookups is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
