Rated 1 out of 5 stars
after trying this add-on and finding it wasn't suitable, I removed it, only to find a Thunderbrowse splash screen littering my folders. No surprise that it isn't documented anywhere, and obviously no mention of how to get rid of it.
Mozilla should clamp down on add-ons that do this - what other undocumented and unwanted things has it done to my system? As far as I am concerned this is MALWARE.
That's the start page for the browser (for clarity, ThunderBrowse adds a startpage because it's a browser). It says in the FAQ how to change the page if you would like and in the wizard there is a checkbox that says "Use ThunderBrowse startpage?" and proceeds to explain what it does.
