It did warn me about closing with several tabs open.
I'm thinking about totally wiping-out (uninstall, remove registry entries) Firefox and starting over with a clean install to see if that makes any difference. Did you do a clean install or just an upgrade?
Chrome came preloaded
My suggestion would be to get rid of it completely and then do a clean install.
Loaded Opera, didn't much car for that after a fairly quick look.
I know a few people here, including Brett, love Opera, but I've never been able to wrap my brain around it—it's just too confusing.
Initially it was a clean install on a new machine.
But I was so frustrated I uninstalled and installed 16.0.1 thinking that might be better. Unfortunately, that came with an "instant Upgrade" to 17.0.1 and i couldn't find a way to get the old version without the instant upgrade.
So I uninstalled the whole mess again and reinstalled 17.0.1.
[added] I may have been too optimistic, I just now open FF again only to find that it had somehow installed the Yahoo! Toolbar without asking.
I deleted it and restarted the machine and reopened FF, no Y! Toolbar. We'll see how long that lasts.
I hope you won't need it , but in one of these Firefox upgrade threads I posted a link to Mozilla's FTP server where you can download any previous version of FF. I'm sticking with 16.0.2 for now and have turned-off the automatic upgrade stuff. If you can't find it SM me and I'll give it to you.
Not sure why people are having such a bad time with FF. My Mint (linux) system offers updates as soon as they become available (a very short while after mozilla releases them) and the only bad point, apart from the stupid version numbers, was that 16 killed tabmix, which I rely on quite heavily. A visit to the tabmix web site and I found a dev version that loaded and works fine.
Out of interest, which OS is being used by those complaining here of faulty FF installations?
