Opera has been updated to v29.0.1773.0. And now everithing is OK with GHOSTERY. Thanks to developers

I found that this situation caused by GHOSTERY extention.

The only way is delete "Preferences" file by path:
C:\Users%USERNAME%\AppData\Roaming\Opera Software\Opera Developer

This way you lost all your Extensions installed before and have to reinstall it again, exept GHOSTERY.
Or complete Opera reinstall...

GHOSTERY works with Opera Developer 29.0.1770.1 until next history clear ONLY...

All previous versions of Opera Dev. with GHOSTERY was Ok.

1. Opera developer 29.0.1770.1 have a serious bug.

After clear all history option (all from beginning), Opera crashes and don't start again.
The option "--no-experiments" doesn't help.
The only way is complete Opera reinstall... until next history clear. It's terrible.

Any suggestions?

Please, do something with my DISQUS account: "ingviowarr". Seems it was blocked by mistake.
It was handy to report about Opera bugs through DISQUS and some time ago you answered to me on some questions too.
