RescueTime has relevant documentation, including instructions to make this work with unsupported browsers.
What Browsers does RescueTime support? - Orion is not on the list, as expected.
Using RescueTime with a non-supported browser - Instructions for how to use it anyway. In case the link goes down, the method is:
- Install the appropriate browser extension for your browser's codebase—Chrome or Firefox
- Sign in with the email you use for your RescueTime account. It is important that you make sure the "I'm already using the full RescueTime application on this computer." box is unchecked. It seems counterintuitive, but it will allow the plugin to record time in that browser instead of the application.
- Tell RescueTime to ignore generic time for that browser. Visit your All Activities report and find your browser activity in the list of activities below the chart. You're looking for just the browser, and not the individual websites that are logged with that browser—i.e., Chromium, Opera, Waterfox, etc. Click the edit icon next to the browser and then choose Ignore this activity forever. This will prevent duplicate time from being recorded by the full RescueTime app and the plugin.
However, when following these instructions the extension does not stay logged-in on Orion - Login screen continues to display when clicking the extension icon after logging in (regardless of whether the desktop app checkbox is checked).
