After going through a thread based on Opera 12 upgrade I installed. I have a 1mbps internet network. The upgrade was fine and there were no issue. I really like the customization features this browser showed me. It was cool to have those new themes. On https://addons.opera.com/en/extensions when I click on multiple add-ons under Speed Dial or other, I am getting 502 bad gateway error. This happens very frequently. But when I open and add one plugin at a time this does not appear. Does this means opera is quiet slow in adding multiple add-ons. I am using Google Chrome also. Where on Chrome Web store you have to click on a app and a message appear to install. This was similar on Opera. You get a popup box to add. Sometime when I click on Add to Opera button, it does not respond. My internet connection is good so I can conclude that issue lies with Opera 12. Does any faces that. Is there any fix for it.
