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

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

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.

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

Goto the URL opera://flags/#PasswordImport, enable the import flag and restart Opera. Then, goto the URL opera://settings/passwords, click the 3 vertical dots to the right of "saved passwords" and choose to import the csv file.

For the specific format of the CSV file, export passwords to a csv file from the same opera://settings/passwords 3-dot menu in any Chromium-based browser and look at the CSV file in a text editor.

@bbildman You probably just have to wait for a fix. Or, for now, you can goto the URLs opera://settings/adBlockerLists and opera://settings/trackerBlockerLists, when adblocking and tracking are enabled, disable a list that's enabled, restart Opera and see if the crashes stop. Maybe you'll find that it's a specific list (or lists) that's the culprit.

An alternative though would be to leave Opera's adblocking and tracking protection disabled and just use uBlock Origin.

@deathcat There's an "AI button in toolbar" option at the URL opera://settings/ai that can disable it if you don't want to disable the flag.

@karen-arzumanyan You can goto the URL opera://about, take note of the "profile" path, close Opera and look in the "Extensions" folder in the profile folder. If you see a "temp" folder, delete it to see if it helps.

Another thing you can try is to goto the URL opera://extensions, remove all extensions, close Opera and in the profile folder, delete the "Extensions", "Extension State", "Extension Scripts", "Extension Rules" and "Local Extension Settings" folder. Then, in the "IndexedDB" folder, you can delete any folders that start with ````chrome-extension```.

Another thing you can try is to delete any folders in the root of the profile folder that have "cache" somewhere in their names. You can then go up one folder level to the root of the user data folder (where you see the "Default" folder) and delete any folders there with "cache" somewhere in their names.

Another thing you can try is to goto the URL opera://about, take note of the "Cache" path, close Opera and delete the "Cache" and "System Cache" folders in that path.

Another thing you can do is to start Opera in safe mode and see if it still happens. If it doesn't, you can troubleshoot more by only using --disable-extensions for example to see if the issue goes away. If so and you don't have any extensions installed, it could be one of Opera's built-in extensions that's causing the issue.

Another thing you can do is completely disable adblocking and tracking protection at the URL opera://settings/privacyProtection and restart Opera to see if that helps.

@bidoux Nice. If you ever need the deb package to work, see https://www.reddit.com/r/operabrowser/wiki/opera/linux_libffmpeg_config/.

Regular Opera or Opera GX?

Deb or Flatpak or Snap package?

What specific Opera version as shown at the URL opera://about?

@Green-Gursewak Goto https://www.reddit.com/r/operabrowser/wiki/opera/custom_site_panels/.

@SpecterK1 The forums here run on NodeBB. NodeBB doesn't provide an option for users to hide their post history/activity.

They do have a feature request section at https://community.nodebb.org/category/5/feature-requests. You could search to see if anyone has asked for it and upvote the request or make your own post if not.

@rastanz The only catch with the standalone version is that you can’t set it as the default browser without extra work.

@Zayedmustapha Opera supports most extensions from the Chrome webs store. Does that one not work in Opera for you?

@Footytang Same thing happen in a test standalone installation?
