opera://flags/
Are you currently running any experiments?
At the moment, the only way to tell is to scroll through that long list and watch out for entries that are not set to "default", or, for those that only have a button, are enabled.
Similar to opera://extensions/ or opera://plugins/, it would be helpful if experiments could be filtered down to show only active (i.e., non-default) or inactive (i.e., default) entries.
Thank you.
