not working anymore please update it
i love opera but i'll have to migrate to chrome

@jeremynwest: I hope you try it and tell me what you think .

@jeremynwest: I found my own way and it works just fine with most of chrome extensions
in extensions manager enable developer mode from the top right corner
download .crx files using crx extractor using any chrome based browser -that would be the only time to use it- using 7-zip extract it to a folder
back to opera extension manager choose load unpacked then chose the folder you have just extracted and voala it is there and working .
you can use the very same method to instal crx extractor on opera so you don't need the chrome based browser any more .
you can drag and drop crx file to extension manager too but most of the times it didn't go very well with me

@jeremynwest:
The problem is I like opera much more and with this extension I had no problem at all until now

not working anymore please update it
