Hello Angelina, portable windows link directs to the stable version page.
btw, both setup (non-portable) and portable versions can be installed as portable as an option, why do you give two links every time?

I use opera at my work computer. my company uses its own certificates. with developer v66 it started not to connect to any sites, then I moved on to previous stable versions and there were no problem.

now with stable channel updated to v66 and now I can not connect to any sites even on stable channel, neither.

what did you change about certificates, or security? what can I do to solve this?

Kornella, for a very long time; first link works, but second link that mentioned as "portable" directs to the stable versions page: https://www.opera.com/computer

@deluxive: you're a saviour, thanks.

I don't know the main source of program (most possibly ublock origin) but ublock origin crashes latest opera dev build (66.0.3494.0).

de-fi-nite-ly.
