THIS ADD-ON NEARLY DROVE ME CRAZY!!! Rated 1 out of 5 stars
I have used this app for a number of years now and through a number of versions and updates. I really like the idea of an Opera style speed dial add-on set as your home page but sadly this app has always been full of bugs. Long standing problems are: creating/deleting tabs, moving/deleting dials and running scripts. It will eventually cause problems with Firefox, which will start running slow, will go into endless loops and then crash.
I would install this add-on and at first things seamed okay, no problems, but, once your tab/dial count goes above a certain count the problems seem to start. I would get script error messages and things would then get progressively worst. It took a lot of frustration and wasted hours trying to track down my 'computer problems' to this add-on. If you have problems with Firefox freezing or crashing and you use this add-on, try disabling it or as I have done, totally remove it and see if Firefox and your computer runs better.
I now keep things simple and use 'MyBookmarks' as my home page, no dial previews but I can live with that. I have also tweaked my Firefox HTTP browser settings and set them to 'optimized' using 'Fasterfox Lite' which seems to speed things up a little - at last I now have a stable and quick browser!
