DoNotDiscard is a free Chrome add-on developed by Martin Wiechmann. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory.

The main purpose of DoNotDiscard is to prevent Chrome from suspending specific tabs and reloading them when you switch to them. By default, Chrome has a feature that automatically discards tabs to save memory, but this add-on allows users to disable this auto discard feature for a custom set of URLs.

The add-on provides a list of URL keywords that can be managed to keep the auto discard feature turned off. By matching the URLs with the filter list, the tabs will not be automatically discarded.

To check if the add-on is working, simply open "chrome://discards/" and verify that the "AutoDiscardable" column is off for all tabs that match the filter list.

DoNotDiscard is a useful tool for those who want to have more control over tab suspension in Chrome and ensure that specific tabs remain active and accessible at all times.
