I am something of a ‘power user’ when it comes to web browsing. I tend to have up to ten separate windows open, each one of which could have as many as 10-15 tabs open at any one time.
I used to use separate browsers depending on the content, Maxthon for certain things, Opera for others. I tried IE and Chrome and Safari, but finally ended up with Firefox. Opera had been my favorite due to its ability to explicitly save multi-windows sessions, but its memory usage wasn’t great (though when you have up to 150 tabs open at once, you are definitely going to have memory problems generally anyway), and Firefox would easily (enough) remember your past session so you didn’t have to worry about losing it (which last time I checked still plagued IE and Chrome). Memory usage still sucked, but the number of times I had to restart a session to clear it was less frequent than with Opera.
So, when Firefox finally released version 4.0, after 17 years in development, I was hopeful it would provide a better experience.
Perhaps, eventually, it will. But, once I upgraded to the latest and greatest, Firefox started crashing, about every 10-15 minutes. After 7 or 8 of these crashes in a row, I figured I’d roll back to the previous 3.6.whatever. First of all, it was really hard to find, but eventually I did.
And, great, now I got the same behavior, crashes every 10-15 minutes, or if I was actively browsing, 3-5 minutes.
So now I’m in the process of starting from scratch, killed off the 10 window session, and am trying to recreate them one by one. Very productive.
