[Solved]Opera 32 Extension Issue
I updated Opera to ver.32 on Mac OS X Yosemite (10.10.5). Extensions issues happen! The location of official "Pocket" Extension's (ver.1.9.6) button on Twitter Web was moved.
Pocket (formerly Read It Later) - Opera addon
In the case of Opera 31, This extension's button and other Twitter button (reply, Retweet, Fav, and so on) is in a straight line.
And Evernote official extension "Clearly" (ver.10.6.1.8) happen issue. If I used "Reading Mode" of this extension on the webpage, Sometimes Other tab's pages change to "Reading Mode", too.
Clearly - Opera addon
I don't think the reasons of these extension's issues are these extension's problem. Because these issues doesn't happen on Opera 31 and I think Twitter web's detail don't change.
I found the condition of "Clearly" issue! It is "Pocket" website! If I opened the webpage by a new tab on Pocket website and used Clearly extension on this webpage, Pocket website changed Reading Mode of Clearly extension, too. I made the screencast.
I updated Opera to latest version (32.0.1948.69), these issues were fixed! Thank you!
I think maybe the reason Pocket Extension's issue fixed was the updating of this extension. Because this extension was updating in 2015/9/25.
