@burnout426 I tried setting Chrome as the default browser instead, but after locking and unlocking Chrome opens, and opens the Bing tab.
That means it’s not Opera and is something on your system causing it.
See https://www.reddit.com/r/operabrowser/comments/1sfn6w0/opera_air_automatic_ambience_switch/ for a user wishing that there was an auto / system ambience mode.

I am guessing this could be due to META changes?
Facebook is getting rid of messenger.com and going back to loading messenger via https://www.facebook.com/messages/. So, yeah, any differences you see are caused by that.

While Opera is still running?
If Opera is set as your default browser, temporarily set a different browser as the default and see if that browser opens when unlocking your computer instead.
For Opera, you can delete the "Sessions" folder in "C:\Users\yourusername\AppData\Roaming\Opera Software\Opera Stable\Default". It'll wipe out all your open tabs, but it my fix the issue.
I would scan your system with the free version of Malwarebytes and AdwCleaner. Sounds like you have some malware that's loading bing on Windows startup in either Opera specifically or the default browser in general.
You can open up regedit and look in "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run", "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" and "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Run" to see if you can find any shady startup entries. You can also look in "C:\Users\yourusername\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup" and "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup" in File Explorer for shady startup entries there.
You can also open up the Windows Task Scheduler, select "Task Scheduler Library' and look for a shady task in the list. You can start at the top of the list, switch the task to the "Action" tab and use the down arrow to go through each task to see if you see a task with an action that's like "path to opera.exe" "https://www.bing.com/" or just something with "bing.com" in it.
In Opera itself, make sure you don't have any shady extensions at the URL opera://extensions.
On the startup tab in the Windows task manager, if you see "browser_assistant.exe", that's Opera's browser assistant that will sometimes show an Opera icon in the systray. It should be unrelated to your issue, but right-click it and choose "disable" if it's there.
What version of Opera GX are you using as shown at the URLs opera://about and opera://version?
What operating system?
Read through https://www.reddit.com/r/operabrowser/comments/1r8s74v/comment/o6j5jk4/ and its replies, especially the last reply.
https://yu2go.com/paketi/48h-test/ loads fine here in Opera 129.0.5823.65 64-bit on Windows 11 23H2 in the U.S., for what it's worth.
I don't think I've ever seen a mod that uses manifest v2. They should all be v3.
keepa.com notifications are working in Opera Stable 129.0.5823.44 64-bit on Windows 11 23H2 now too.
Can you create a demo HTML file with a simple file chooser input and some simple JS that reproduces the issue?
Also, does the issue happen in other Chromium-based browsers like Vivaldi, Brave, Chrome and Edge too?
To install VPN Pro, you need to have the 64-bit version of the .NET 8 desktop runtime installed. See https://dotnet.microsoft.com/en-us/download/dotnet/8.0.
Newer versions of .NET are supposed to be backwards-compatible these days, but unless the bug in the VPN Pro installer was fixed, you need to have 8 installed directly.
I just tested the keepa.com issue in Opera Developer 131.0.5853.0 64-bit on Windows 11 23H2 and it's fixed. See https://blogs.opera.com/desktop/2026/03/opera-131-developer/. Youtube notifications should work now too in Opera Developer.
Not sure if it will help with errors, but you can try to launch Opera GX with the --no-sandbox command-line switch.
@MehmetAliYCL There seems to be an older package at https://aur.archlinux.org/packages?O=0&SeB=nd&K=opera-gx-stable&outdated=&SB=p&SO=d&PP=50&submit=Go. Nothing new for the latest 128.0.5807.97 though.
@ZenGDev Any difference if you start Opera GX with the --no-sandbox command-line switch?
If not, it might be that Opera expects a certain Glib/GTK version or it's something to do with Deepin's DTK customizations on top of GTK.
Are you talking about https://chromewebstore.google.com/detail/scite/homifejhmckachdikhkgomachelakohh? If so, you should be able to goto the URL opera://extensions and remove it if it's still there. If it's not there, maybe you just need to goto the URL opera://settings/clearBrowserData and clear "Cached images and files" for all time.
