I think Mozilla are so concerned in upping their bloody version numbers that they've forgotten about product quality lately. Why am I so pissed off? Because in FF8, I had something like 20 tabs open that I would keep there for days and even weeks. I upgraded to FF9 the other day and everything was good. Started it up this morning and it crashed on startup, showing a blank window with a bit of display corruption at the top. I waited for a bit, but it didn't sort itself out, so I had to kill it with Task Manager. When I started it again, all the bloody tabs were gone, apart from one showing my homepage. WTF? To compound the problem, the options are still set to show windows and tabs from last time. However, if I open up more tabs, it still only starts up with that hometab only. Changing this configuration option, saving it and then setting it back again doesn't f* help! I saw this just before I went to work this morning, so I've not had time to troubleshoot it any further. My advice to people is to stick with FF8 for the time being until Mozilla patch this, if they do. I might well try downgrading it tonight. EDIT: Note that the tabs had survived multiple browser restarts and system reboots before this happened, so it's not a "compatibility issue". It's just a serious bug.
