Yesterday something strange happened. First opera in my computer started crashing without any new extension installed or setting changed (although I remember changing the speed dial background). Eventually I uninstalled and deleted all the opera folders in my computer (appdata too) and used CCleaner to delete old files and registry. Rebooted.
Reinstalled again but the beta version and after sync my account it started crashing too. Didn't know what happened but did a reset again(deleted only appdata/roaming folder) and its fine now.
Today it's happening in my phone too.
What is this?
