Stop Tab Discards
How do I stop Google Chrome or Microsoft Edge auto-discarding the WhatsApp Web tab?
If tabs are not used for a while, they can be auto-discarded to save system memory. For example, a WhatsApp Web tab can be auto-discarded resulting in the interruption of WhatsApp messages being sent through the Walution add-on. This article describes how to disable the auto-discarding feature in Google Chrome and Microsoft Edge.
In Google Chrome or Microsoft Edge, type about://discards in the address bar and press Enter to open the Discards page - chrome://discards in Chrome and edge://discards in Edge.
Locate WhatsApp in the Tab Title or Tab URL column.
Click on the Toggle button in the Auto Discardable column, so that an X appears in the Auto Discardable column for the WhatsApp Web.
Now Google Chrome or Microsoft Edge will not auto-discard WhatsApp Web tabs, and interrupt WhatsApp messages being sent through the Walution add-on.
NOTE: The modified settings above apply as long as the WhatsApp Web tab remains open. If the WhatsApp Web tab is closed, the web browser is closed, or the computer is restarted, the auto-discard feature needs to be disabled again. For a long-term solution, there are a number of extensions available in the Chrome Web Store that prevent auto-discarding.
