Goto URL opera://settings/startPage. You'll see a suggestions option that you can disable (among other things).

Goto the URL opera://flags/#search-in-open-tabs, disable the flag, and restart Opera.

Test this solution. Remove the Opera Safe Store password from Keychain Access login item.

Steps:

Open Keychain Access application

Choose 'login' keychain on left

Choose 'Password' group

Find 'Opera Safe Storage' entry, right click it and choose Delete.

You can goto https://addons.opera.com/en/wallpapers/?tag=animated and install one of the animated wallpapers. Then, in Opera, goto the URL opera://about and take note of the "profile" path. Then, close Opera and look in the "themes" folder in the profile folder.

You'll see the folder for the wallpaper you installed. In it, you can see how to create your own. You then just zip up your persona.ini file with the webm file and thumbnail and you 'll have your custom wallpaper.

Things you can try:

Goto the URL opera://about and take note of the "profile" path. Then, close Opera and delete the WidevineCDM folder in the profile folder.

Then, start Opera, goto the URL opera://components, click "update" for Widevine, let it update, and restart Opera.

Then, start Opera and goto https://html5test.com/ and make sure it shows "yes" for h.264 support and "yes" for aac support.

Once that's good, goto https://bitmovin.com/demos/drm, make sure it says "Using Widevine" above the video and "Widevine" for EME below the video, and "video/mp4; codecs="avc1.42c00d" for MSE below the video. And, make sure the video plays and you can hear its audio.

Then, goto the URL opera://settings/siteData, type spotify.com in the search-cookies field and choose "remove all shown".

Then, goto https://open.spotify.com/ in a new tab, log in, and try to play some music.

If you still have problems, goto the URL opera://flags/#reduce-user-agent, enable the flag, restart Opera, and try again.

If you still have problems, goto the URL opera://settings/system, disable hardware acceleration, restart Opera, and try again.

If you still have problems, goto the URL opera://extensions, disable all your extensions, and restart Opera.

If you still ahve problems, make sure you're not using Opera's VPN, and try turning off Opera's Adblocking and tracking protection.

If you still have problems, try all of the above with a standalone installation.

You can also goto the URL opera://settings/content/protectedContent, and make sure "Sites can play protected content" and "Sites can use identifiers to play protected content" are set with no sites in the custom behaviors list.

In the Opera program files directory, right-click on launcher.exe to create a new shortcut and place it on your desktop. Then, on the desktop, rename it what you want. Then, right-click on the shortcut, goto properties and then the "shortcut" tab. On that tab, modify the target to add the --user-data-dir command-line switch.

For example:

"C:\Program Files (X86)\Opera\launcher.exe" "--user-data-dir=C:\Users\yourusername\Opera2"

(I personally have a "My Program Files" folder in "C:\Users\myusername", so I'd use "C:\Users\myusername\My Program Files\Opera2" for example.)

You can create as many shortcuts as you want with each using a different profile folder.

See http://peter.sh/experiments/chromium-command-line-switches/#user-data-dir for more info.

Log into https://gemini.google.com/app in a tab.

Then, enable the "Custom user sites for browser sidebar" flag at the URL opera://flags/#sidebar-site-panel, restart Opera, click the 3 dots at the bottom of the sidebar, scroll down to Custom Site Panels and add https://gemini.google.com/app.

As an alternative for now, note that you can enable the "Custom user sites for browser sidebar" flag at the URL opera://flags/#sidebar-site-panel, restart Opera, click the 3 dots at the bottom of the sidebar, scroll down to "Custom Site Panels" and add the URL for the web app you want (https://bsky.app/ for example).

You can't customize the icon for it in the sidebar and you can change its position, but it's something for now.

If you have any trouble logging in to the site in the sidebar, you can log in via a regular tab first and then reload the sidebar.

Goto the URL opera://about and take note of the "profile" path. Close down Opera and delete the WidevineCDM folder in the profile folder. Then, start Opera, goto opera://components and try updating Widevine again.

You might want to make sure opera://flags/#new-component-update-mechanism is disabled too. It should be by default, but check that URL just in case.

Are you talking about the start page button that's missing on the left side of the address bar in Opera One builds?

@Jerry12302 said in Can't stop Opera from starting on PC startup or login:

I usually only lock my PC

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.

See https://www.reddit.com/r/OperaGX/comments/1rmtbbn/comment/o9up6zv/ and https://www.reddit.com/r/OperaGX/comments/1s4gdc4/hard_limit_option_missing_on_ram_limiter_4gb/.

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?
