I definitely was having stability issues with FF4 on OSX. I solved it by disabling the Java plugin.

Apparently this has been an issue since early beta releases of FF4, and Mozilla has yet to correct it.

If you don't anywhere that that requires Java (we're talking full Java for applets here, not javascript)... then disable the "Java plugin for NAPI Browsers" and get a "poor man's" security benefit... and get the improved speed of FF4.

But yeah... I agree... Mozilla needs to get their shitte together... fast.

does it merely refer to the widespread practice of collaborative development of software with a new complete test edition created every 24 hours incorporating the latest programming work, completed or not? That is, nightly?

By the rate they are going now with upping the version number with each tab move, you will get your FF9 this summer at the latest...

We all know Mozilla couldn't meet a deadline if it was to save their life. Let me be the first to call BS, nice try but you're not fooling anyone. Given FF has been nothing but crap since 3.0 and continues that legacy well into FF 4 I have Internet Explorer style expectations from anything coming out of the Mozilla camp from here on out. FF 4 is just a pathetic attempt at stealing the Chrome interface and not really fixing a damn thing else.

I haven't been able to print since Firefox 2!

Its great that FF developers move tabs around and have hardware acceleration that sometimes works - but printing would be nice.

Maybe by FF8 or FF9 they will finally get the generic text driver working again.

After all - ASCII printing is so very, very complicated... I guess all peons should be grateful since Chrome printing is even worse...

FF4 is garbage. I had to downgrade to 3.6 because it wouldn't do some simple task and crashed. All for a cosmetic change?

I've only just upgraded to FF4 and it doesn't really do a lot more than FF3, it still surfs the internets and does lolcats and pr0n. What more do I need from a browser?

As far as I can tell the tabs are closer to the top of the screen now. Worth the upgrade? Hardly.

Firefox 4 'final' is pretty unstable for me already, I get at least daily crashes, with no hint as to the cause, even with all extensions disabled!

They'd do better getting Firefox 4 properly stable.
Sheesh!
