Can't save custom domain. Can't use this plugin at all

Doesn't work on linear. No time tracking shows up where it shows on the linear integration page, nor does the extension track the visited issues at the top.

works. After installation do not forget to open Options and enable the domains where you want to use it. (E.g., enable todoist, gmail, etc.) Otherwise, it won't work on those domains.

Tried and couldn't make it work with Asana. Not what I expected.

Appears to work quite well, but also is pegging pretty high CPU usage. Are there performance improvements that can be made so this isn't a battery killer?
