@overcomplicatedhermit said in Need delayed loading of background tabs on startup:

I've been searching for this and I think I've discovered that Opera used to have Delayed or 'Lazy' loading of background tabs, but the setting is no longer there since 3023. Is that right?

It was there in a long time ago but the option got removed. Not sure why. I don't think Opera ever gave an explanation. A change in Chromium probably broke it and it was too much to fix it. Not sure. It was removed way farther back than 2023 though.

Is there no way to keep tabs open at startup without auto-reloading?

I don't think there's any way to do it in Opera now. Not sure if there's a Chrome extension that can do it either.

Vivaldi has the option you're looking for though.
