1) There is no sensible way to import my Speed Dial from another install. The suggestions in the Support forum were all FAIL.
2) Without any sense to it and despite plug-ins being disabled just for it, YahooMail has begun crashing after hitting Send again.
3) To prevent the crashes, I installed an Ad Blocker.
4) Now Opera crashes about four times an hour.
I am fast getting sick of this shit.
