Evernote is available for free today. This is a pretty good note taker program that has been around for ages. If you are familiar with OneNote, then you will be fairly familiar with how this application works. If not, then go take a look at the main Evernote homepage
I can now upload images in firefox again. (see this post for when it failed).
I ran firefox in safe mode using firefox -safe-mode and I was able to upload an image to flickr ok. This meant that the problem was a conflicting/corrupt/flakey extension. I went through my list of extensions and deleted some that were duplicate in other extensions and tidied up the ones I no longer needed. I removed informeter, livelines,tab clicking options, undoclosetab, sitebar and evernote extensions and the problem went away. I reinstalled sitebar and evernote (as I use these) and the browser doesn’t crash.
