Thanks for tour reply.
Does it mean that every day there is an update of Opera?

I was already using the latest version today. And the extension ws not working correctly. I restarted the browser and it started to work. Strange.
As said in my first post, there was no issue couple weeks ago.

For some time I cannot fill in automatically login / password by clicking on my saved credential in Opera browser. I have to do it manually by selecting / copying data.
Using other browser with extension, it works.
Why it's happenning ?
