This has been a real sticking point for people wanting to use Opera as their main browser. The extensions offered on other browsers simply make a lot of tasks easier. A lot is built into Opera already, but this addition could be a real turning point.
Good news, everybody! Today, at Up North Web, Opera Extensions was confirmed to be a feature of Opera 11. What are Opera Extensions?
Extensions will be based on the W3C Widget specifications and this is being considered for an Open Standard effort.
Will Opera Extensions be similar to extensions in other browsers?
Yes, Opera Extensions will be similar in some ways and we have tried to make it easy to port extensions from certain browsers.
