Love this product. Google maps is useless without it. HOWEVER, recently trying to put some charts on a website and Fusion Charts is not working well with this addon. Causes Firefox to totally lock up. I've got to 'end task' and restart Firefox. I disabled all addons and Dark Reader is not compatible with Fusion Charts on Firefox. I'll keep using Dark Reader though and find another charting library. If the developer would like to see the issue, just load Fusion Charts. The home page has some samples which will freeze Firefox.
