@payard You can't set a specific shortcut for a custom site panel. However, at the URL opera://settings/keyboardShortcuts, you can set a shortcut for the "Show sidebar" command to toggle the showing of the sidebar. I like to set it to F4 as that's what old, Presto-based Opera used to use. But, you might want to use a different shortcut.

вполне рабочее расширение

convenient, use it sometimes

this thing is really good

Things are about to change; more and more gamers are switching to Linux, aka SteamOS, Bazzite, CachyOS, etc. Microsoft is losing user trust and handheld gain in popularity.
The train has left the station, and I can't believe the OperaGX team will miss it.
I hope it's only a matter of time. Just do it!

I'm also having this issue. It might have been because the settings for each workspace are different? I went into the settings for the current workspace and user account and verified that they are set to retain tabs from the previous session.

Alas I'm afraid to test if it's working because when I go to close a window with zero tabs, I get that pop up, "are you sure you want to close..." and then lists a number for tabs that will be closed. I presume those (that it is saying will be closed) are tabs from another window, but I don't know for sure and it shouldn't default to that.

@Adilbastos The problem also happens on a regular tab?

Just to add to the list: I saw the same error with "chrome/browser/process_singleton_posix" when updating to 125.0.5729.12 on Ubuntu. I "fixed" it based on @zibi1981 suggestion above, as follows:

From my crude understanding, it would again point to wayland vs x11 issue, but anyway, just sharing in case someone else ends up here after seeing opera crash on startup in Ubuntu.

@bkelloggsr: yes i emailed him after i uninstalled/reinstalled to tell him that i forgot to make note of my activation key so he reenabled pro for me.

@iamchristianramos Hello. I disabled the few apps I used. And I tried them one by one. That reset Aria in the sidebar. In any case, this AI has little life left. They will soon replace it with Opera IA. Personally, I'm using another browser now.

@metana
@Opera-QA-Team could you plz check this out?
