Among the financial institutions I deal with and whose online facilities I use regularly, Citibank India, HDFC Bank and ICICI Bank have had great support for Firefox. The only exception was Standard Chartered India who did not seem to want to support anything other than IE or Netscape Communicator 4. I had pointed this out to their Customer Service several times and even pointed out where in their JavaScript code they were making the mistake, but I was always presented with a verbose, albeit nicely written, message asking me to just use the supported browsers and stop ranting. Needless to say, I was irritated and frustrated.
To my pleasant surprise, I discovered last week that they had silently started supporting Firefox as well. Perhaps it came about because a lot of their developers themselves use Firefox; perhaps a lot of customers actually complained; perhaps they saw that by most accounts, Firefox has around 8-10% of the "browser marketshare". Whatever be the reason, I am happy. It is also heartening to note that a lot of sites these days increasingly seem to just work with Firefox instead of requiring IE.
