Better translation.
I've been using the latest Opera USB for two years on my laptop (Win7-64 2012).
An example of an error. I can't open the picture:

Note. The error started around June 2021.
From June 2021, some sites began to open slowly. Some sites stopped opening.
Since October 2021, 90% of Internet sites began to open very slowly, or stopped opening at all.
Since January 2021 I have updated the root certificate isrgrootx1.der (Win7-64 2012) from https://letsencrypt.org/certs/isrgrootx1.der
25% of Internet sites began to open, and quickly.
But Opera did not open 100% of Internet sites.
Today I downloaded the latest SlimJet browser. Same error.
Today I downloaded the latest Firefox browser.
Firefox opened 100% of Internet sites quickly!
Because Firefox contains built-in certificates.
I turned off the Firefox option:
'Query OCSP responder servers to confirm the current validity of certificates'.
Firefox opened 100% of Internet sites very quickly!!
That's why many people upgrade Opera to Firefox…
But Firefox has too old a design and too few options…
