I downloaded Firefox 4 Beta 10 yesterday on my Mac.
It was released just days after Beta 9 and I’m not sure what all the differences are between Beta 9 and Beta 10 are but I had been using Firefox 4 Beta 9 since it was released and I really liked it, so I downloaded Beta 10 to stay up-to-date.
Firefox 4 Beta 9 was the first version of Firefox 4 I tried out. Previous to that I had been running on 3.6.13 and I found it quite buggy. It would quite often freeze up completely, requiring me to force-quit it and it is not like I have a huge number of Add-ons installed.
Anyway, Firefox four is a huge improvement. It runs extremely quickly, is very stable and from an aesthetic point of view it is a really gorgeous browser (not often you hear me say that!).
Even things as mundane as adding a link in WordPress look fabulous compared to the same dialog in Safari (v 5.0.3).
There are other cool features associated with Firefox 4 as well (like the ability to sync tabs etc. across machines, new Add-on management, tab organisation – I really needed this one! and more) and they are all outlined on the Firefox 4 Beta 10 features page.
Many of them you’ll probably never use but for me, the beauty of this browser and its stability are enough for me – I’m not going back to Firefox 3 again.
