@korochigrilob: It's just that it might not be a virus, however, if Opera blocks it, it's because this site doesn't meet the minimum requirements to be approved as a reliable site. We don't care if it's because it's a pimply teenager, (French expression=>a nice guy, but who is limited) who practices and doesn't know what he's doing, or if it's a virus. The fact that the question arises is enough for me to delete the application concerned. I've had too many problems with the "we'll install it, then we'll see" mindset...

we are on November 17, 2022, I have the version 92.0.4561.61, and after the update of opera, lost a part of my bookmarks, but not all... No doubt, losses related to the update of opera, related to the update of chrom... (it was just for information to say that opera, is still not repaired)

ne fonctionne pas sur tous les sites

13 August 2022: he works very well

2021 oct - il fonctionne - he works

It works very well now. You have to remove the check mark from the 1st proposal (Do not change video quality if an HD quality is selected and the preferred quality is also HD) which is set automatically, because if you want 1080p (which you have chosen at the top), but there is 1440p , you will get 1440p

Finally. Opera will accept your addon, thanks for putting the link and info and sending emails to everyone

@talionranger117 la version beta d'Opera (il met le lien sur d'autres réponses)

@bobcat22 I don't think we should make these reproaches, it's his interest to the developer, to be able to have more and more people on his application. it was his case. He left a note saying, that he was going to try to do something. Then another one, where he said he couldn't do anything... I notice that extensions that work well, conveniently get blocked pretty quickly. Google (as you say is disturbed by these applications) must certainly attack these applications, because they are good, and they allow to download videos with a good quality.

It works very well. Well done ! One small idea, could you install a translation which would be displayed automatically once the selection of the sentence is completed with the mouse, without having to click on the icon, which pops up next to the text ..? Personally, I don't need to make this click, since I select on purpose to have the translation.
