Tuesday the 19th, a new Firestorm Viewer version was released, 5.0.7.52912.
You can download and install this new version. There is no need to remove the previous version you are using. Some of us (yes, me) have noticed it crashes shortly after its first launch. On the second and subsequent launches, it seems fine.

I suggest you restart your computer before installing. Inara in her review of this release (here), recommends backing up your viewer settings before starting the install. I didn’t have to restore any settings. BUT… if you are changing from 32 to 64-bit version, a settings backup is a good idea.
The Firestorm team has a goal to release an update every 3 months. It has been 6 months since the last release. So, there is a lot of work in this new release. Plus, they say it is very well tested.
