I'm having the problem with my current version 69.0.3686.36 - however, I've been having the problem for a couple of years. It only effects my Opera browser on my Linux (Ubuntu 18.04.4 LTS). Nothing shows up in 'saved passwords' but some of the passwords that have existed in my systems, even for a long time, are being auto populated - but no new ones. It doesn't seem to do anything when I chose to save a password after I enter it even tho I say yes to saving it. I was wondering if there might be an issue with writing permissions. I have to enter my computer password in 'KDE wallet' every time I open up Opera

leocg - do you happen to remember which estension? Thanks

The older Opera had a way to 'tell the internet' that it was a different browser. It was very useful when visiting a site that had been designed to be viewed using Internet Explorer. Other browsers have use 'IE Tabs' to accomplish a similar thing. Is there anything like that available with Opera today?
