...but I can't completely.

The features are terrific.

Otherwise, FF 1.5 still has the habbit of consuming 6-10% of my CPU with only a couple of very static pages loaded. (macfan2004: I noticed the 100% usage problem when I first upgraded to 1.5, but that disappeared in less than 10 min). Disabling plugins does not help.

Safari normally uses <1% of the CPU under the same conditions, and its a bit quicker in general than FF.

Also, there are a couple new problems: On certain large pages, drop-down boxes will cease to drop when they are clicked; Instead they just highlight (although you can still change the selection with the cursor keys). Context menus accessed via holding down the right mouse button on an HTML link don't behave quite right; The menu is 'sticky' and when I release the button over the desired menu entry, it just sits there (the menu stays up and the menu entry isn't selected). Actually this occurs with more than just links (the background of this comment-posting page, for instance) but the behavior isn't consistent. Sometimes it behaves correctly.

FF 1.0.x had a memory leak problem (as does Safari), but I've only used FF 1.5 for 3 days at present, while the memory leak would only become pronounced after 5-8 days of usage without restarting the browser. So I can't tell yet if FF has fixed the memory issue and the (slight but noticable) stability problems. Overall, FF seems to use rather less memory than Safari.

IMO the Linux version is of somewhat higher quality and consistency than FF for Mac. My feeling is that Mozilla doesn't *quite* know what they are doing on this platform, and/or they have trouble taking the Mac seriously (which would be a huge mistake for them to make with the largest Unix userbase and growth trend, by far). As the saga with KHTML and Webkit has shown, the Mac arena has a great deal (if not more) creativity, muscle and user-focus to offer FOSS projects like Firefox than the priestly server-room culture permeating that, um, 'L' operating system. It is time for Mozilla to wake up and finally get their browser 'done right' on Mac OS after all these years.

Pages render very well in FF. And some of the extensions are great fun and indispensible. I use Scrapbook extension to archive interesting web pages (and websites) that I come across; Flashblock is another extension that only runs embedded Flash animations when you click on them (a great nuisance-avoider).
