Actually, there's a brainstorm currently on how to implement a more elegant solution, but no ETA as of yet.

The startup sequence has been seriously redesigned for Opera 41 as described here: https://www.opera.com/blogs/desktop/2016/10/86-percent-faster-opera-41-for-computers/

Can you please confirm that the setting "Delay loading of background tabs" is not taken into account and loading is the same regardless of the setting state? Thanks.

Hi all - the issue was investigated for some time and it seems that the solution has been found. As described here, the newest beta should contain the fix. Would you please care to check out if it works for you? Thanks!

Thanks. This should be fixed in the next release of Opera developer.

You should have Opera 41 by now; the current version is 41.0.2353.46. Can you try with this version?

Also, if it still does not work, you can temporarily turn off the extension or any other extension you might have installed, reload the page and retry. Did it help, hopefully?

Thanks for the report. Investigating.

Edit: Seems it's the issue of an overzealous blocking list in the ad blocking solution. So the list itself would need an update if you want to use the page; or, you can turn off ad-blocking on this page.

Nevertheless the proper fix for this issue is on its way too.

If it's NPAPI it won't work. You would have to install the PPAPI version of Flash Player.

Hm… Can you please install in a separate location as an USB installation ans see if the problem still exists?
It could be some profile issue.

Ok, thanks. Actually, it is a very good idea.

Are you using synchronization?

Please clarify: they used to work in Turbo but suddenly stopped, or you started using Turbo and they don't work there? Also, can you please provide page examples? Thanks.
