It would be great if the browser automatically enables/disables the data saving feature depending on the type of the network that is being used at that moment (mobile data vs WiFi). For WiFi often people don't want the data saving feature and prefer to have a higher speed, but for Mobile data they would want to sacrifice some speed for less data usage. Is there a way we can convey this message to the developers such that they see how many people support this and like it?

Hi all. It has been a few days now since I have this problem. When I try to open any page with *.google.com address (e.i. google search, gmail, drive.google.com, etc.) I get the following error:
"You attempted to reach www.google.ca, but the server presented an invalid certificate.
You cannot proceed because the website operator has requested heightened security for this domain."
with a back to safety button. This is happening with google chrome as well. I use Opera 36.0.2130.65 stable 64 bit on Windows 10. Anybody has the same problem?

It is Windows 8.1 64 bit.

Ok, thanks. Now I did another test. Looks like the problem is the "click to play" setting. I have this setting active in Chrome as well. The difference is, in Chrome, I get a kind of warning in the right of the address bar with a plugin icon and a cross on it. And I can tell Chrome to run Java plugin on this page. But in opera there is no such sign.

An update. I disabled all the plugins and the "click to play" setting. Then refreshed the page and it worked. Now, I enabled all the plugins again and the "click to play" (to find the one that is causing the problem) and after all that, it is still working! However, it does not work on another page.

Thanks for the quick reply. I checked Opera menu, Developer Tools, Plugins, and I have Java, and the button bellow it says "Disable" so I assume it is enabled.

Hi everybody. I have been trying to make opera run java plugin, but I could not succeed. Does anybody know how to do that? Almost all the browsers run java on my computer (Google Chrome, SRWare Iron, Firefox, ...). For example, I try this page:

http://java.com/en/download/installed8.jsp

and it does not run on opera. Any idea?

Opera has had this image on/off button since long long time ago, and it is gone in the new interface. I used to use it frequently when I had a slow connection or limited traffic. Now that it is gone, is there any way I can bring it back?
NOTE: What I need is per tab image on/off and the ability to load individual images from context menu. Also, the ability to load only cached images will be very helpful. These features are now available in the "ImgLikeOpera" addon for Mozilla's Firefox.

Many thanks everybody.
