The first answer
First save your work. This setting addresses inactive-tab reloads; it is not a diagnosis of every reload.
Check the symptom
Google says unused tabs may be deactivated and reload when selected. Note whether your reload follows inactivity.
Add one exception
On desktop, open More > Settings > Performance. Beside “Always keep these sites active,” select Add. Choose an open site or enter its address, then select Add.
Review the result
Our suggested check: record the site and your previous setting, change only this exception, then observe the next return. If reloading continues, keep that result for further troubleshooting; avoid repeatedly adding broader exceptions.
Before you change it
- Save important work.
- Keep the change narrow.
- Record the result.
