Thanks for the information. A pity Opera is not in Ubunt(yet) because it's become my totally favourite browser after having tried the other week known browsers.

Onderwerp: [Bug 1906421] Re: Opera froze, incl.the whole system, a couple of times
Datum: di, dec. 1, 2020 18:59

There's no "opera" package in Ubuntu, so filing bugs on the Ubuntu bug
tracker cannot succeed in having these fixed, I'm afraid.

If this is about the Opera web browser, I suggest to look for available
support channels on https://www.opera.com

** Changed in: opera (Ubuntu)
Status: New => Incomplete
