How do I use this addon? Rated 1 out of 5 stars

Unfortunately I have no idea how to use this addon. There are no instructions.

Can someone advise how I use the CSS Viewer?

One of my must-have Firefox add-ons! Over the years I've had to do several workarounds to get it to install properly with the latest Firefox version, but it's totally worth it. The simple overlay quickly displaying the final rendered CSS properties is a handy time-saver. Only on occasion does the z-index of the overlay compete with other elements on the page making it unusable. For the most part, it works awesome!

It's working... However it has some problems.
1. the main problem is when I want it use can't see. No toolbar button or a Context menu item. First I need to open the browser menubar and find the CSS viewer. I don't use menubar and in the new versions of Mozilla the menubar is hidden by default.
The only way is the following: hit on Windows ALT key to unhide menubar > hit on Tools > and then hit on CSS viewer
Afterwards if I don't want use it more times I must to do this way again
hit on Windows ALT key to unhide menubar > hit on Tools > and then hit on CSS viewer
2. on long text code the the running outside the box
3. the box sticking out of the browser window. So it is not adapted to the window frame.
Overall is it a good and 'fast' way to view the CSS property of a website.

Spent about 3 hours trying to find the HEX for a colour on my website, and found this little Add-on, and tried it , I found the colour hex in about 5 seconds after enabling it. This is an amazing tool! :)

The version of Firefox 21 on Ubuntu works just fine. However, the existing problem of displaying long text codes.

Getting the showed text Rated 5 out of 5 stars

Great!. Please add a way to get the text from the viewer (a copy button or hotkey). I use FF3.6.8 and FF19.
