I have two Win Pro 10/64 computers. 67.0.3575.31 exhibits the same problems as described by AnthG--no go. I completely uninstalled it together with my data. On the other Win Pro 10/64 works fine. I will attempt to reinstall once again but without any data retained and report back, but I am doubtful. It installed and seemed okay--UNTIL I tried to Sync it--then it reverted to not responding behavior like before. On the other computer it is sync'ed, so I don't get it. Opera, you have a problem. Seems to work briefly while attempting to sync, then bombs out before syncing, while attempting to do so. I will once again uninstall, including the data, and refer back here to see if Opera has fixed this, only using it without any synchronization. Yes, I am using another browser to report this, the Chromium version of Edge, FWIW.

I am not an advanced user, but unless Opera is getting revenue from the Messengers that it carries, or adding Signal is somehow otherwise infeasible, look into it. Would go with the free VPN service--in theme. (I know, WhatsApp is encrypted, but not as well. I don't use it.)

For example the current Opera v. 67.0.3575.31 corresponds to what version of Chrome? Why? This: https://www.zdnet.com/article/chrome-80-update-cripples-top-cybercrime-marketplace/ Is there a way to tell that for future reference?

@xb70 Now the other computer that was working while sync'ed, is exhibiting the same behavior--"not responding," so long as attempting sync.

@xb70 I miswrote tabs, when I should have posted bookmarks within the bookmark bar.

@jimmybfmv I am referring to the order of the saved bookmarks in the bookmark bar.

@treego I don't know what WorkSpaces is. Opera 67 doesn't allow me to synchronize--it bombs out, "not responding," if I sync, so no tabs on Opera for me until they fix that.

It does not appear that Opera can retain any attempt to organize tabs, beyond whatever its default is--order of retention? Whenever I have attempted to sort them into a useful order--to me--once I reboot, the order is back to whatever Opera does--no memory of what I sorted, except as long as my synchronized session is in effect. This is very frustrating. Can someone advise the trick to get Opera to remember my organization past the current instance of Opera?

Thank you BlackBird71! From XB-70 (Valkyrie).

Bingo! My bad for not thinking of that, especially given the extensions: the culprit was Block Image Video, version 0.1.0 by Alex Marcoo, which I had intended to block display of images and video (those pesky downloads of videos and ads, which I don't ever want). Opera Ad Blocker was fine, as was Disable HTML5 Autoplay
Version 0.6.2 by eloston
Trying to blame Opera--so poor on my part.

Vanguard.com no longer works well with Opera. Many pages do not load, rather a grey page opens (blank) when various other things are expected. This started back at v. 59 something, and continues into the latest v. 60.0.3255.27 I have not contacted Vanguard.com as they will likely tell me that they do not support Opera, whether Chromium based or not. Still works on IE (my other browser). Do I have to abandon Opera now and finally install Chrome? I do not know if other Opera users also use Vanguard.com, but if so, please weigh in. Thank you.
