@NewWorldMan Yes. https://www.waterfox.net/ My main beefs are the same with all chromium based browsers, not opera specifically.

I gave opera a shot but will be returning back a waterfox. While pages seem to load snapily the memory usage of the browser was bit high. I did like some things but they are not enough to make me switch completely.

The things that I liked:

1.) builtin ad blocker
2.) builtin vpn
3.) pop out windows
4.) Side Bar tools.

things that are deal breakers

1.) unable to customize tool bar button.
2.) unable to remove speed dial completely, even when disabled in settings. (new tab should just be blank new tab)
3.) memory usage is not as efficient as waterfox on the sites I use.
4.) ad block still had ads that were getting through even with a custom rule set.
5.) no updated help for ad block filters and regex.
6.) Lack of customizations for tab handling (this happens with most chromium based browsers)

I think opera is far better than default chrome from Google, but still suffers from the same usability issues as that ecosystem.
