Fennec F-Droid sync

Hi there!
I would like to know how I can do so that Fennec F-Droid automatically synchronizes every 1 h., every 2 h. or the time that I choose.

Refreshes a page you mean? Try to find an extension…also whitelist Fennec in any battery optimisation…

No, I mean Fennec F-Droid synchronization with my Firefox desktop account.
