@Mlipka Sorry for the late reply.
I don't know why, but I feel like Opera is against the use of extensions. Firstly, Opera Air has trouble supporting extensions. Then there is Opera Neon, the AI browser, which has high potential of making extensions meaningless due to its AI capabilities. The employees are not updating the Opera addons page which of course looks very outdated and has barely any good extensions. I have also seen you people often share links from the Chrome web store instead.
And now you are asking if there is any specific extension I need to install, as if you and your team would like to implement it in the browser itself. I mean, there are infinite possibilities with extensions.
I might be wrong or have misunderstood this, but this is what I get from a bird's eye view.
