Bitdefender has warned me many times of expired certificates that Opera attempts establish connections with. I don't have this happen with any other browser. It happens at different sites. Why is this happening?

@dianam212 Because the certificates are outdated?

Are you being able to access those sites?

No. Bitdefender blocks them. Not very safe for a supposedly safe browser. Should I find a different browser? I only continued to use Opera because it was supposedly safe.

I have a list of many. The only reason I really liked Opera is because it saves PDFs. I can probably find another browser that saves PDFs.

Thanks

@dianam212 Nothing to do with the browser, it is either an extension you installed or a site you tried to visit (which Opera would have blocked if BitDefender hadn't already done so).

Check if it's an extension by disabling them - if that stops the problem then you can enable them one at a time to figure out which it is. If the problem persists with extensions disabled and you not actually visiting sites then you have some sort of malware or adware sending you addresses for bad sites.

@sgunhouse I deleted Opera and am using Brave. It doesn't happen with Brave. And it never happened with Google Chrome or MS Edge. What a coincidence that it only happens with Opera and that Bitdefender states that "Opera Is Using expired certificates".

As the image shows "opera.exe attempted to establish a connection relying on an expired certificate" but I am sure that it must be the extensions that I don't have in Opera that are causing the issue. I don't even like extensions.

Sometimes, no answer is better than a bad answer.

@dianam212 If it was a bad answer, how come others who use Bit Defender don't have similar problems?

I have this problem too.
I uninstalled Opera and reinstalled it. This problem has ocurred again . That isn't a extension.
I ran malwarebytes and can't find any malware.
This problem occurs even Opera uninstaltion.

@cbareis Maybe a false positive from BitDefender?

All those rejections seem to for opera internal sites - maybe you have some certificate problem on your computer?
Navigate your non-opera browser to exchange.opera.com (this does not redirect you elsewhere) - what does certificate info show? Is certification path visible and valid?

Strange. Chrome and Edge work as expected. Firefox (and Opera) are blocked by Bitdefender. Certifcate for exchange.opera.com is certainly neither expired nor revoked; IMO Bitdefender is at fault here.

I would contact both Opera and esp Bitdefender support, Opera issue can be reported from O menu - Help - Report an issue..., most likely Bitdefender has some feedback page either.
