I really hate it when software updates break things, particularly when that update is to Firefox and the thing it breaks is the one extension that makes me love Firefox. I've just installed Firefox 2.0, which means I've just discovered that 'extensions' have now become 'add-ons' and that the one extension I loved is not compatible with 2.0.

I love Tab Mix Plus, and I'm glad to see that there's going to be a new version soon, but surely Firefox is sophisticated enough to scan through our extensions and tell us if there are any that are not going to be compatible? I would have waited a week to install Firefox had I realised that it would break my favourite extension.

So I'm going to try Flock for that week. Annoyingly, you can't import your bookmarks from Firefox into Flock, which means I had to port them from Firefox to Safari and thence into Flock, but I seem to have mislaid some along the way.

Kevin's been raving about how great Flock is - seems it is finally fulfilling some of the potential I saw at BlogOn last year. I'm not sure if I'll move my blogging from Ecto to Flock, but I might give it a shot. Certainly Flock's Flickr uploader is better than either 1001 or Uploadr, so I'm already converted there. Still, I'll spend a little time setting things up, and I've set Flock to be my default browser, and we'll see what we see.

Meantime, shame on you, Firefox. For the next release, how about you work on notifying us when we update if you're going to break things?
