Discarded tabs

How to enable it

Extension Preferences > Settings (tab) > Tabs Opening > Discarded

Current discarded method

How does it work

• Open in the tab a custom extension page that is empty
• The tab is only load once you active it
• The icon is still loaded from internet

Limits

• If you uninstall/disable the extension on Chrome (only), those tabs, not fully load, are closed. It is because, they are only extension pages.
• In rare cases, the automatic reloading is not working
• The extension is doing some magic to show you the expected tabs in the interface, however other extensions might be disturbed

How to reload manually

1. GO to the tab that didn't reload.
2. It contains an URL, copy it. (It is the URL saved when the group was closed)
3. Paste it in the URL bar, and open it.

Reason the official discarded method is not used

1. It is impossible to open a tab immediately in discarded mode:

• Chrome: NO
• Firefox: Support the "discarded" property inside browser.tabs.create()

2. The API browser.tabs.discard needs first that the tab is fully load. So, it is not interesting for groups opening. See A Tab Created then immediately Discarded is invalid: It cannot be Reloaded
3. Firefox (only) is not able to discard all the tabs (Example github tabs), because an event is used on the page. See 1420681 - Add forceDiscard property to tabs.discard
