@leocg Sorted thanks.

I've deleted Opera and installed the latest version from the Snap Store, but I can't find a way to remove the + Add a site button or the Search bar.
How can I remove these two elements from the Speed Dial (new tab) page?

Running Ubuntu 22.04.1 LTS

System recently updated Opera to V92.0.4561.33 via the Snap Store

Since then videos from various sites that used to play OK constantly stop to buffer, this didn't used to be the case.

Same videos run perfectly well in other browsers on the same machine, network etc.

What should I be looking at?
