Kindly reminded if your OS is not macOS, this addon can't work without a wrapper script to call the external dictionary software for safety reasons. The following guide require a little programming skills. Please check How-to-use for detail. This addon is forked from another Firefox addon https://cup.aihedy.com/en-US/firefox/addon/mactionary For more detailed description with pictures, please check the github repo of this addon. https://github.com/Harpseal/LookUp-Dictionary-By-dict-URI-Scheme Update for firefox 84+ users There is a new permission dialog to approve after firefox 84+. Please open the Options page of this addon, check the checkbox, press the save button and try to look up some word. The temporary tab for dict scheme will not be closed and leave the permission dialog for user to approve. After the permission is approved, please uncheck this checkbox in the Option page for normal use. For more detail pleace check the How-to-use step4. * How-to-use When user right-click on any word on any website, the "Look up in dictionary" will appear in the context menu right away. Please select it, and this addon will send the clicked text or selected texts to the dictionary software which supports dict Uri scheme. (ex. dict:///keyword) The dict:/// Uri scheme is supported by the build-in dictionary software in macOS. If your OS is Windows or Linux, please take the following steps:

Prepare the "wrapper script" before installing this addon. (require programming skills)

The example scripts still need some customization. Please trace the scripts and customize for your system.

C:\Tools> look_up_dict.exe dict:///test

Add dict:/// Uri scheme handler

After some version of Firefox 57+, Firefox ignores all unknown URI scheme (ex.dict:/// on Win/Linux) and doesn't show the "Launch Application" window as before
