Opera automatically fetches a page when it starts

As mentioned earlier, the fetched page wasn't the typical Hearty
Journal page but rather the Cloudflare challenge page, implemented to
deter automated bot access. Typically, users encounter these pages in
unusual situations, such as error 403, 404, 500 and 503. If possible,
could you provide the exact URL that Opera fetched?

If you continue to face difficulties resolving the misconfiguration,
please consider resetting or reinstalling the browser. Once again, I
apologize for any inconvenience caused. Thank you for your
consideration.

@chennien Thank you for the help.

I can't get the URL because the message that shows up doesn't give me any clue about the URL Opera follows.

All I do to get this message is typing opera & in Linux command prompt.

Somehow, Opera used to repeatedly fetch this content.
This time it seems to have fetched the content only once, immediatly after Opera is launched from command line.

If Opera doesn't repeatedly fetch this big content, I consider to leave it as it is.

@masaoliu
Ah! Opera, and only Opera, repeatedly and automatically fetches this content, when only one this web page and Opera tab is opened.

Hi @masaoliu,

In the last line of the image you posted: "source: chrome-extension://obhaigpnhcioanniiaepcgkdilopflbb/background_worker.html (0) ", the code doesn't belong to any of our pages. It seemed to be appended by the browser. Could you please check the info of the extension?

masaoliu

masaoliu @chennien

@chennien I have only two extensions, both are disabled.

I will be removing all of them after I have made this comment. I will come back to comment if the auto fetches completely stops.

==Edit==
I can't find a way to remove these extensions. They seem to be mandatory.

@masaoliu I visited hearty.me and the issue began on my device. To resolve it, I went to
opera://serviceworker-internals/ opera://serviceworker-internals/. Then, I pressed CTRL + F and searched for “hearty” and related terms (“.me”, etc.). I found this:

So I unregistered the process, restarted Opera, and the issue was gone.

Let me know if that works for you. It did for me. Best of luck!

It seems that the outdated service worker (https://hearty.me/sw.js) handling installed PWAs was causing unexpected fetching behaviors. I've now updated the code and unregistered the worker. Please let me know whether the issue is resolved. I apologize once more for any inconvenience.

@bestcodes Nice!

masaoliu @BestCodes

@bestcodes Thank you very much!
I can't find the entry *hearty" in opera://serviceworker-internals/.

I renamed directory /home/john/.config/opera/ to /home/john/.config/opera-bak again, and this issue is gone.

I suspect some files in /home/john/.config/opera/ are broken.

I will try to manually migrate bookmarks and saved passwords, etc. from /home/john/.config/opera-bak/ to /home/john/.config/opera/.

Strange that didn't work before, but glad it's gone doing it this time.

Solved with ~/.config/opera removed.

Thank you all for the helps!
