Safari Extensions

These are extensions for Safari that I’ve created. To use them:

  1. Download one of the extensions below.
  2. Double-click on the downloaded file to install.


AnySearch allows you to use any custom search engine you want in the Safari address bar. Alternatively, it allows you to disable searching completely, returning to the old Safari functionality of only allowing web addresses.

ChEMBL Search

ChEMBL is a database of bioactive drug-like small molecules. This Safari extension allows you to right-click on any compound name and choose “Search in ChEMBL” to display a popup with an image of the chemical structure. Clicking the ‘View’ button will then take you to the compound’s page on ChEMBL.
