A Google AdWords Help thread has one Opera browser user complaining that he can't sufficiently manage his Google AdWords account using that browser.
The Opera user said:
The AdWords interface does not work with Opera. Are there plans for this to be made possible some day?
Google actually replied to him. Paddy from the Google AdWords team said:
We value your feedback. I can put this forward to the relevant team as an ask to consider in future. Thanks very much.
This reminds me of the frustrated iPad users not being able to manage their accounts using an iPad. I am not sure on the status of that but I believe it still is not a 100% functional. There are some iPhone apps people can use to manage their accounts. There was also some speculation of a mobile AdWords management site but I have yet to see that come about.
Using Opera? Switch to Chrome. Okay, switch to something else besides Opera for now.

I noticed that Adwords doesn't support Opera about 2 months ago - Politely told me that I needed to use another browser...

Yes, I have the same problem, I've had it for quite some time. I have to switch to Firefox for that (I'd use Firefox all the time but it slows my computer too much). But I don't understand why everybody pushes Chrome on people, Chrome is horribly designed. And what do you mean, does Opera still exist? Of course it exists and it's a great browser! It's not as friendly looking as the older version but it's still way better than Chrome.

Opera is the best browser out there (it's my personal opinion, and I've used them pretty much all). It's a shame the AdWords interface still doesn't work with Opera, which, by the way, is a flaw in the design of the AdWords interface, not a flaw in the execution of code in Opera. It's still highly annoying to open up another browser just to manage you AdWords account, since that uses up additional resources (RAM). I'd prefer to do it all in one browser and use tabs.
