The reason why this has never been removed or an option for removing it has been added is because Opera doesn't care or really want developers using their browser.
We are not their main target and we're the furthest from their mind so using the extension linked above is the best solution we'll get.

This update broke Discord for me. Is anyone else affected?

@burnout426 Thank you! That's exactly what I was looking for

@leocg
DNA-98390 DevTools’s console warning about copying scripts

@leocg There is a big difference between one site having it and every single site having it.
I have to see that warning in sites that I work on and it's not only distracting but it also removes space from logs.
For me that's an indication that Opera shouldn't be used for Web development.

@andrew84 The issue wasn't with the browser itself, it was with a built-in extension. Opera is able to update built-in extensions without updating the browser like with regular extensions

Thanks for fixing the out of memory crash when using devtools and refreshing the page

@ralf-brinkmann Go to opera://system/, Expand all details and check the extension list. What version do you have for Aria?

This is my machine:

igpdmclhhlcpoindmhkhillbfhdgoegm : Aria : version 4_5_0_2

@ralf-brinkmann How do you get updates to extensions at the moment?

Every Chromium browser is able to remotely update extensions, this is a completely separate process from the regular browser update.

If you didn't get an Aria extension update then the issue is with your setup

@hsikorski: Thanks for the quick fix! I can confirm that this is no longer happening

@spike666 Cause seems to be the Aria Writing Mode Assistant extension (chrome-extension://igpdmclhhlcpoindmhkhillbfhdgoegm/). Does anyone know how to remove this?

@spike666: I'm having the same issue. Seems to be a result of writing text in a textarea

Ever since I updated to this version writing into a textarea (including this one) causes Opera to use a large amount of memory and CPU. To the point where my entire PC freezes. Is this related to Aria?

@koimark They should just let us name the tab islands.

Other browsers with the tab island concept as well as extensions allow you to give it a name. That's more than enough to turn tab islands into a true organisation tool

@andrew84: I have this as well but it does have hover styling for me
