Besides the ad blocker, consider if there are other active extensions that might be consuming excessive resources. Try disabling them one by one to identify if any other extension might be causing the issue. Since clearing the cache and resetting to default settings didn't permanently solve the issue, look into other settings that might affect performance, such as hardware acceleration. Sometimes, enabling or disabling this feature can have a significant impact on how video content is processed.

Extensions like "Session Box" for Google Chrome and Firefox can facilitate managing multiple Gmail accounts by allowing you to open each account in a separate tab as if it were in its own session. Have you tried any of them?

When you click on "Edit Workspace," try to find the places where you can change the name of the workspace and its picture. Even if there isn't a button that says "edit," you should be able to change these by clicking on them. Also, sometimes, the extra features you add to your browser or specific settings might mess up how things look on websites. You could try turning off these extra features for a bit or use Opera's private mode to browse without them. This can help you figure out if one of these extras or a saved setting is causing the trouble.

Today's popular web browsers, including Google Chrome, Mozilla Firefox, and Microsoft Edge, allow users to log in to multiple Gmail accounts at the same time. Additionally, there are extensions or plugins tailored for managing multiple accounts, like Multi-Account Containers for Firefox or Chrome profiles in Google Chrome.

After you've uninstalled the program, there might still be some files hanging around. On a Windows computer, you'd want to dive into folders like C:\Program Files, C:\ProgramData, and the AppData folder under your user account. If you're using a Mac, you're going to look in the Library under Application Support and Preferences in your home directory. Any VPN PRO files you stumble upon in these spots should be deleted.
Now, if you're on Windows, there's this thing about the registry where old settings can linger and mess things up. You might need to clean it out with a registry cleaner, or if you know your way around, you can use the Registry Editor. Just be super careful, as deleting the wrong thing can cause more headaches.
After you've cleaned up, give your computer a quick restart to shake off any of the old settings or temporary files that might still be clinging on.
When you're all set to install the new version of VPN PRO, on Windows, make sure to right-click the installer and select "Run as administrator." This step makes sure the installer has all the permissions it needs. On a Mac, double-check that you have admin rights, or you might need to pull up Terminal and use some commands for the installation.

@henname OMG! It looks like your computer is possessed or something. That's really weird. What about other browsers? For one of my laptops, the Safari browser acted strangely. It opened many different tabs and only updated the entire system, and the help of VPN helped me to solve that issue. But nothing like that I had with other browsers.

I had the same issue in another browser (Mozilla, to be more precise), but I noticed that this issue does not work with all videos. And as you've said, they disappear when I go full screen. But I dunno what causes it.

First, remove the old VPN PRO program. On a Windows computer, you can do this by going to the Control Panel and looking under "Programs and Features." If you're on a Mac, open the Finder, find VPN PRO in the Applications folder, and drag it to the Trash.Then, turn off your computer and turn it back on. This helps get rid of any leftover files or settings that could cause problems when you set up the new version of VPN PRO.

@henname Okay, in this case, it might be a stupid question to ask, but are you sure that your browser is updated to the latest version?

Even though the problem didn't occur in a different browser, an extension exclusive to Opera could still be the culprit. Disabling extensions one by one helped me pinpoint if an extension was responsible.

Well, if Opera's temperature display is powered by an extension or a built-in widget, try accessing its settings. There might be an option to refresh the data source or to re-enter your location.
