forward, return, links in Yahoo email client not working

In ATT/Uverse/Yahoo email client, Opera is not allowing Some clicks to happen. Can't download, Can't open or close emails, can't reply, etc. I am having to use Chrome or the Windows mail client. In both, the Yahoo email client works as it should. This is problem only with Opera.

@randymartin And isn't reasonable for one to be able to FIND Opera's policy on these matters? I like Opera but their inter-personal support is non-existent.

@leocg Sounds right except that one computer works and one does not. Same Opera, Same extensions. BTW, I do NOT use Chrome at all.

@leocg Good thought. Consider this. On my laptop, I have only 2 extensions: Stick Password and TinEye. SP has a supported browser choice dropdown and Opera is an option. Opera does not list SP. TE does not have supported browser drop down but it does have an add-on extension. My laptop ALWAYS (for the last several weeks) needs to have those extensions enabled. I get the message that a new extension has been added and is unknown and all the extensions are shut down.

My Desktop has the same 2 extension plus 5 others. It NEVER gets that warning and I NEVER have to enable my extensions.

Your thoughts?

@oglena I have 51.0.2830.40 and it STILL disables them. I only have two extensions and one is Sticky Password and I can't auto log in to Opera to do this complaint, I have enable the extensions, log in, and then refind where this forum is. It doesn't automatically go back after the log in. But what gives with the disabling? I wonder if it's because I have FireFox also open? Or is it connected to the synchronization? Seems that it's a common enough problem they should be working on it. I may try Vivaldi. Firefox won't recognize ameritech.net emails sometimes and it sends me to AT&T log in which I have for home system but that's NOT my email and it wants me to change to AT&T.
