<![CDATA[Opera doesn't recognise itself]]>Playing around with user agent switcher (for Chrome), reset it and removed from extensions as it did not seem to be what I needed. Since then, Opera is behaving oddly. I can't download addons ("You need the Opera browser") and if I check a site like whatismybrowser it tells me I am using an outdated version of Chrome. Tried uninstalling and reinstalling, no luck. Tried uninstalling, hunting down remnants and then reinstalling, still no luck. Even tried using other user agent switchers, still no.

I can't figure out how to fix this and it is driving me nuts. Any assistance greatly appreciated, thank you.

launcher.exe "--user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36 OPLR/57.0.3098.76"

Notice the "L" in OPR. If the OPLR doesn't get stripped, then whatever perhaps whatever is causing the issue is looking for opr specifically.

Of course, maybe we're still missing something obvious and simple.

Switch to the Network tab. Click "disable cache". Click the 3 dots at the upper right of the developer tools and undock to a separate window. Click the 3 dots again, goto "More tools" and then "Network Conditions". Then, at the bottom, uncheck "select automatically" for "User agent". In the drop-down for the User Agent, set the user agent to Opera for Windows for example. then, ctrl + r or F5 to reload. Then, switch back to the addons.opera.com tab in the main window. Does Opera get detected right then? If not, try Opera for Mac instead.

Again, maybe this will reveal how the user-agent is getting changed on you.

cd "C:\Program Files\Opera"

(or wherever you have Opera installed).

Then:

launcher.exe "--user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36 OPR/57.0.3098.76"

Then see what Opera gets detected as. Is the OPR part still stripped? If so, does everything else match or is a different version of Chrome and AppleWebkit detected?

Close Opera and try again with:

launcher.exe "--user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:63.0) Gecko/20100101 Firefox/63.0"

Does Opera get detected as that or does it still come up as Chrome?

Doing this may reveal something.

CCleaner can do some cleaning, but there's a better one that often fixes issues. I just can't remember the name of it. Maybe some others have some suggestions.

    • Delete Opera keys in "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall".

    • Delete "HKEY_USERS.DEFAULT\Software\Classes\OperaStable".

    Look for any "Opera Developer" and "Opera Beta" keys and remove those too.

    • Delete "HKEY_CLASSES_ROOT\Applications\Launcher.exe".

    Look for any of those keys/entries under any of the other users listed in the registry and remove those Opera ones too.

    In Explorer, delete "C:\Program Files\Opera", "C:\Program Files (x86)\Opera", "C:\Users\yourusername\AppData\Roaming\Opera Software", and "C:\Users\yourusername\AppData\Local\Opera Software". Delete any "Opera Developer" and "Opera Beta" folders too.

    • Delete any Opera files and folders in "C:\Windows\Temp".

    • Delete all the files that you can in "C:\Users\yourusername\Appdata\Local\temp".

    • Delete any Opera folders in "C:\Users\yourusername\Appdata\Local\programs".

    Opera should then be pretty clean from the system. Then, download the Opera installer, launch it, click "options", set "install path" to "C:\Program Files\Opera", set "install for" to "all users", uncheck "import data" and anything else you want to uncheck and then install. Then try Opera in its default state.

    Then, you'd reinstall Opera.

    Now, you could use a registry cleaner to do the registry stuff first and then check for leftovers. But, this way, you can manually check everything you're going to delete.

    I'm willing to give some registry editing shot, I have a feeling that is where the problem is.

    Never had a problem with the ISP before, and actually just swapped out the router the other day.

Since the opr part is there for the data URL, I'm guessing the issue only affects https and http URLs. This leads me to believe that it's something outside of Opera that's causing it and targeting Opera specifically or targeting Chromium user-agents specifically (and modifying them to remove anything extra like the opr part). If not malware (as you scanned for it for example), all I can think of at the moment is some Chrome/Opera policy in the registry or something to do with your router or something to do with your ISP.

    If you goto addons.opera.com, ctrl + shift + i to open the developer tools, type navigator.userAgent in the console and press enter, what does it say for the UA? Maybe it's fine and the site is just being goofy for you. Maybe restart your modem or something to see if you can get a different ip address and then go to addons.opera.com.

    I checked out the extension. I don't see anything weird about it. In Chrome though, its settings and probably the extension itself can be synced if you're using Google Sync. So, with Chrome, if you started with a fresh profile and turned on sync, the extension my be enabled again on you. But, that shouldn't affect Opera either way.
