@PaperPSI I had this and resolved it by turning off opera add blocker.

I just launched Opera GX browser and noticed that almost everything is gone.
All settings are reset.
All extensions are gone.
I'm logged out of every site and all passwords are gone.
Speed dial page is completely empty. - If I go at "bookmarks" page I see that there is new folder named "other speed dials" and my speed dials are moved there.
What is going on and how to restore everything into previous state?!

Forgot to mention, that when I launch browser it did not start "normally" just browser but with some black box first where OperaGX logo is shown and then it opens browser.
At that time in task manager is present some process named "operaGX splash" (opera_gx_splash.exe). I did some googling and it seems it's not a virus but legit opera process. Don't know if it's related to unfortunate event, but it's something new, as well.

Hello. Can someone tell me how to disable tab snoozing?
In settings, option is disabled, but browser still keep snoozing tabs.

I want to stop receiving updates from OperaGX. Which files I need to delete or block?
I recently got update which made side scroller on the right side of the browser microscopically tiny and pale. For a person with eye problems, now it's almost impossible to see it.
I don't want nasty surprises such as that one in the future.
Thanks in advance.
I understand risks of outdated browser, but it's for health reasons.
