My experiences - Linux redhat 7.1. - On the whole, it works great. No crashes etc. - Finally "click to open the application" works. I had to do some tweaking of ~/.mime.types, and within mozilla profile, mimeTypes.rdf. - Drag and drop of URLs into a folder defined within the visible bookmarks toolbar doesn't work anymore. It used to work in 0.9.4. However, first using Copy, and then using Paste while the cursor is on the specific folder item within the toolbar, will work. - 0.9.4 wouldn't allow me to reply to newsgroup articles. (It would hang.) No problem with this version.
