Like many designers my browser of choice is Firefox – it’s customising options surpass any other browser I’ve tried so I thought I’d share my top add-ins.  I was going to do one of those ‘top 10′ lists, but I changed my mind and limited this to just the four main add-ins that I really find useful.

Colorzilla

This is one of my very top add-ins.  A fantastic tool that allows you to point and click anywhere on the screen and select a colour.  You are then shown the colour as RGB and HEX, you can also save colours into favourites which is useful when compiling a colour palette or matching a colour for a logo to a colour on a company site.  Definitely one I couldn’t do without.

ScreenGrab!

I find the task of taking a screen print rather a painful process, particularly on a mac.  I was delighted when I came across this very helpful tool.  With ScreenGrab you can elect to save or copy the entire page, visible portion, user defined selection or the window.  I personally find this fantastic for copying a page selection to the clipboard ready to paste into my chosen programme.  Mainly, I tend to use this for displaying a new logo onto a pre-existing web site.

Measureit

Selecting this tool brings up a small cross-hair cursor that when dragged across an area of the screen, displays the dimensions of that area.  Useful when asked to make a header fit into the gap above the site content without being given precise details.

ReminderFox

Not really a graphic design tool, but a useful one nonetheless.  Easily add reminders to your browser and set alarms and alerts.
