Ever since the Windows 10 update 2004, Opera has been unstable. While it opens normally and allows me to visit sites, when I attempt to use the extensions Click&Clean and/or History Eraser (both installed via the Chrome web store, because they're not up-to-date on the Opera add-ons page), they'll work but won't allow me to close their windows. Even closing the main Opera window (effectively quitting the program) doesn't help, nor does CTRL+ALT+DEL. I have to go to Task Manager and force Opera to close. And after re-booting, the computer is unstable; so that I have to shut down, wait, and re-start it.
Additionally, if I highlight an unhyperlinked address while the "Go to Address" pops up (or using the right-click menu), it won't go to the web page, and just hangs.
I've already tried fully uninstalling Opera via Revo Uninstaller Pro, re-installing the latest version, then installing extensions. Everything works fine for about 12-hours, before the same problem resurfaces.
Opera is my favourite browser; I've been using it before it became Chromium-based. And one of its best features has always been "Speed Dial". The thought of having to use Chrome (ugh!) or Edge (yuck!) is not a choice I want to make, but I value being able to periodically clear my usage history and those two extensions have never had a problem until this latest Windows update.
I can't be the only person with these problems.
