@halvor-raknes Opera has few/some/a lot of "holes" in functionality. Why do you not want to be a little lazy using pinned tab with opened Qwant page? I use Startpage systematically this way, selecting DuckDuckGo as default.
By the way. If Opera Team wanted to open sidebar to "whatever pages you want" like Vivaldi did, your and other Opera users life'd be more efficient and pleasurable.
Debian Bullseye, IceWM, 2 core CPU with 8 GB DRAM, NVIDIA GT520, driver 390.132, Opera Beta
The first phase (the replacement of the 2 files with the ones from WinXP) worked greatly.
But in this way I lost the bookmarks already accumulated in Win10 (however I preserved those replaced files).
Using the Opera browser function "export bookmarks" created an .html file of the bookmarks in Win10, .html file that
enabled me to import/recover the Win10 bookmarks.
Many thanks again.
@burnout426 Thanks burnout426. I have also been having this problem for a couple of weeks. I was about to follow your detailed instructions when I noticed your comment at the end citing security/anti-virus/firewall software as a possible issue. I had installed Malwarebytes just a couple of weeks ago. So I have just disabled it for a couple of minutes, and Opera has now updated for me. So thanks again, problem sorted, although I am now wondering what other issues Malwarebytes may be causing me !
Knowing my ability to make a mess of even the simplest of tasks I saved my bookmarks to my Laptop and Flash Drive first then followed your instructions in your 2nd post and it's all sorted now, thanks
