<![CDATA[Opera injecting unwanted code]]>Opera is injecting this piece of code while navigating:

<style type="text/css" id="operaUserStyle"></style>

I would like to know why, and how can I make it stop.

Started recently, probably around the version 94.0.4606.65, but it's still happening in the current version 94.0.4606.76.

Steps to reproduce: you can browse any webpage and Inspect it using Developer Tools... this piece of code will be there. Examples:

It's used mainly to fix problematic pages

So, I appreciate your input, but I think you should let someone who knows the answer to the problem to help me, thank you.

It's not uncommon for browsers to add code to pages. They do it to fix problematic pages, to block ads, etc.

And it's happening even with Lucid Mode deactivated (but in this case, it's putting a blank <style> tag and nothing else, but enough to be blocked by an integrity check).

And if you expand it, you will see that it's just the Lucid Mode script.

It's good to know, but would be nice to know if there is some way to solve the problem in the current stable version because this injection of code, even being harmless, is causing Opera to not function at all in some web systems who perform an integrity check in the html code before being able to operate.
