To disable an already activated tab, please make sure to switch to the tab first, then open the toolbar button and disable the job. Note that if you are closing the tab, there is no need to disable the job. The job will be disabled automatically after an active tab gets closed.
As of version 0.2.7, you can now ask the extension to automatically set new reloading jobs for you based on the "Custom JSON" object. If the option is checked and the new page has a matching hostname, the extension will load the custom reloading job from the JSON and applies to the tab. Check the options and FAQs pages for more info.
As of version 0.2.9, 1 you can define a policy that prevents reloading based on the time (date) and URL. Both time and URL keys accept regular expressions to prevent reloading. With the policies you can, for instance, prevent reloading on a specific page of a domain or prevent reloading at specific hours of a day.
