Opera doesn't recognise itself

If after doing all that and reinstalling Opera, if it still doesn't work, you might try a registry cleaner. 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.

Maybe it was https://www.auslogics.com/en/software/registry-cleaner/.

going through registry now. Noticed this on the way:

{
"name": "com.microsoft.browsercore",
"description": "BrowserCore",
"path": "BrowserCore.exe",
"type": "stdio",
"allowed_origins": [
"chrome-extension://ppnbnpeolgkicgegkbkbjmhlideopiji/",
"chrome-extension://ndjpnladcallmjemlbaebfadecfhkepb/"
]
}

C:\Program Files\Windows Security\BrowserCore\manifest.json

not sure if related (Chrome not installed currently)

@aspiring-squirrel I have that too and I think it's legit. See https://forum.adlice.com/index.php?topic=3340.msg7567#msg7567 for example.

No worries, just thought I'd check

OK, went through registry and disk directories, also used Auslogics Registry Cleaner ... No change.

@aspiring-squirrel Okay. Will think of some other things to try later.

In your normal Opera and in standalone installations you try, goto opera://extensions and click "all" if you haven't. Perhaps some extension is getting auto-installed somehow.

While Opera is closed, in a commmand prompt:

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.

Just for addons.opera.com, ctrl + shift + i to open developer tools. 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.

You said you checked for malware. But, any anti-virus software or security software or firewall software that might be interfering?

Another thing you can try:

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.
