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.

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.

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.

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.

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.

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?

This issue is being tracked as DNA-125850 now.

@diazeta Does the shortcut work in 136.0.6008.80?

@urimus I don't think Opera has done any specific fixes for this issue. Seems it's just partially fixed due to Chromium updates or some other fix.

@NatureWithGreenWorld If you search for session in https://blogs.opera.com/desktop/changelog-for-136/, https://blogs.opera.com/desktop/changelog-for-137/ and https://blogs.opera.com/desktop/changelog-for-138/, Opera has been working on some session fixes. In Opera stable, you can turn on Early Bird at the URL opera://settings/early_bird and enable "Emergency session restore" to see if it helps prevent your tabs getting reset next time.

You can goto the URL opera://settings/userInterface and disable "Show tabs from the same domain in tab tooltip". It'll disable that feature in the tab tooltip. It won't disable the tab tooltip itself though.

You can fake it for now. See https://www.reddit.com/r/operabrowser/wiki/opera/custom_site_panels/ and then use opera://easy-setup or opera://settings or a specific section of settings like opera://settings/appearance.

For some of those, you'll want to make the panel wider so you can see enough of the page.

For now you can fake it. See https://www.reddit.com/r/operabrowser/wiki/opera/custom_site_panels/ and then use opera://password-manager/passwords or opera://password-manager/settings depending on which you want to load.

Note that you'll want to increase the width of the panel until both the left and right panes on the page show.

After you goto the URL opera://settings/importData, choose "Bookmarks HTML file" and point it to the HTML file with your bookmarks, you need to goto the URL opera://bookmarks in a tab.

On the opera://bookmarks page, find your imported bookmarks. They might be in the root of the "Bookmarks Bar" folder or in an "Imported Bookmarks" folder in the "Bookmarks bar" folder. Wherever they're at, just like in Windows Explorer (File explorer), you can select (one, many or all), cut or copy, and paste from one folder to another to move or copy items. Shortcuts like ctrl + a, ctrl + x, ctrl + c and ctrl + v work too.

As for the imported speed dials, they should be somewhere on the opera://bookmarks page (in an "other speed dials" folder or something) where you can select and move them to the main "Speed Dial" folder. Then they should show up on the start page.

@ss9227 OK. Definitely strange.

@nefloppa117 and chose a different language in the installer?
