The title of this thread says it all. The previous version of Opera Developer before Opera Developer 42.0.2392.0 worked fine with respect to the Web Panel (sidebar) extension for viewing Twitter and Facebook in the sidebar. I use https://m.facebook.com and https://mobile.twitter.com for this extension.
