RStudio IDE keyboard shortcut issues with Firefox


If you have customized keyboard shortcuts in RStudio Workbench (previously RStudio Server Pro), using Firefox, and seeing issues where keys are not being registered properly, you may need to edit the Firefox setting privacy.resistFingerprinting.

A potential fix to the issue is:

  1. Navigate to the about:config in Firefox. Type about:config in the search bar and hit enter 
  2. Search for privacy.resistFingerprinting 
  3. If the value is set to true, set it to false
