I’ve been using Firefox on my MAC as my default system browser for years until I got really irritated with the need to kill it once in a while after it became non-responsive. Switched to Google Chrome, but was still running Firefox for testing of my HTML/JavaScript code with the great add-on Firebug.
It looks like its time to say good bye to Google Chrome. Periodically, it just start rendering Web pages blank. I found a cure that works sometimes – grab the corner of the window and start slowly resizing it. You might get lucky and find the size that Chrome likes and start rendering the content again. Being an enterprise developer I can’t imagine releasing an application into production that once in a while shows a blank screen to the users. I have no idea how Google can get away with it.
You may suggest that I should file a bug. But what do I write in there? It doesn’t render the content once in a while? Steps to reproduce: just freaking run Chrome for a couple of days with a dozen of opened tabs.
What’s next? Safari. Let’s see what the future holds. Keeping my fingers crossed. If you know of any Safari surprises, please let me know. I’ll still be using great Developers Tools of Chrome though – it’s a great tool.

I recommend use Opera for “web surfing” + Firefox and FireBug for testing.
Why do you like Opera?
Fastest, tabs grouping, speed dial, good mail client, synchronization (like in Chome), pin downloads tab and many many other advantages.
I like Opera as well, seems to be the fastest one so far, although the Mac implementation tends to hang sometimes. I think the most stable is Safari, yet it is by far less fast and responsive.
But the greatest pain in the ass is the flash player of course; it plagues all browsers under Mac 🙂
