Which Opera version are you using? We're still supporting Opera versions 39+ so if you're experiencing any problems with a supported Opera version please let us know so that we can look into those to get them fixed.
Anyway, you can find a list of all versions of the various extensions we have released on this page.

Makes sense then because we dropped support for the final Chrome/Opera versions that supported Windows XP with the release of Adblock Plus 3.7.
However, Opera wasn't supposed to download that update and I'm not sure why it did so thanks for letting us know about this issue. I'll look further into it to see whether this also occurred to other Opera users on Windows XP.
