Rated 4 out of 5 stars
Have been using QuickJava for a while. Great extension. Would be nice if we are allowed to move the icons around or select the colour easily.
For my own purpose, I move the Proxy button to the left most position, changed the colour to brighter Green and Red, and reducing the spacing by 1 px.
Use the "Customize" and put them in whatever order you want (even on the Add-on bar, just use the options to hide all of the existing icons). Most people don't use the Proxy so by default it went to the furthest location. Green was not used because for colorblind people (including myself) they are too hard to differentiate. If you want to code for custom colors please feel free to do so and send me the code and I'll include it. See the support website for more info on that. Thanks for your input.
