Limit the Maximum Number of Loaded Lightning Console Tabs

To improve memory usage and the scalability of console sessions, set the maximum number of loaded console tabs. Open tabs that exceed the limit stay open, but they only reload their content when you click them.

When this feature is enabled, it doesn’t unload your currently open console tab.

Recently opened tabs aren’t unloaded for a 30-second period, even if you exceeded your loaded tab limit. After that period, if you activate a tab or open a new tab, your background tabs are unloaded. Tabs are unloaded in the order of least recently used until your loaded tab limit is met.

Tabs for pages with unsaved changes also aren’t unloaded. In console, these tabs have an asterisk (*) at the end of the tab title. To customize how unsaved changes are handled in Lightning Experience, use the Unsaved Changes API.

When enabled, this feature doesn’t unload tabs that use pinned region templates. For information on pinned region templates, see Salesforce Help: Customize Lightning Pages for Lightning Console Apps.

Setting the loaded tab limit to 0 and then clicking Save disables the loaded console tab limit.
