Same problem since the very 1st build of O72. Everything was fine on O71.

@andrew84

According to the changelog youre fixing your own bugs, not the user ones.

https://ftp.opera.com/pub/opera/desktop/65.0.3467.42/win/
There's another build.

@burnout426: the issue is pretty compilcated. You have to install AdGuard for Windows and AdGuard browser extension. In this case AdGuard browser extension should work in Integrate mode (blue icon). But when we open ANY page from Speed Dial the icon is green and the integrate mode doesn't work. That's not only one windows program that doesn't work correctly with recent Opera versions. It's broken since Opera introduced that new "fast opening" Speed Dial. I reported the issue to AdGuard and they told me that it was broken in Opera and their new Speed Dial implementation...
I also have another windows program that uses browser extension (Internet Download Manager) and it also doesn't work correctly in case of Speed Dial.

DNA-83177 Page content is scrolled up when switching tabs

Thank you for fast fixing this bug and another build of Opera this week!

The bookmark bar’s folder dropdown no longer overlaps the bookmark bar.

Thanks, but the long bookmark folder dropdown still overlaps the tab bar. Please fix it.

@burnout426: I can corfirm that.

Finally. Thanks.

Thanks for the new build!

Please fix it.

You better update Chromium asap...

Please fix the blog post link on the changelog page. It goes to an old version.
It would be nice also if you could update Chromium engine to *.190 soon.
Thanks!

CHR-8308 Update chromium on master to `

This line should be fixed on the changelog page.

I hope that Opera will update Chromium engine to 88.0.4324.150 soon as there are some 0-day vulnerabilities...

@ralf-brinkmann: no problem with the video here, too. Everything is fine.

@leocg: yeah, that's correct. We have to check the bug on the next dev update (the one after 75.0.3953.0).
