Web Development through Browser extension

[brian]

Currently, I am using Firefox and Firesizer. In order to check the responsive design of my site as the development is in progress. But firefox is creating many problems after the recent upgrade. And good browser extension other than Chrome is more preferred.

Any suggestions?!!

Why aren't you considering Chrome? It provides almost every resources.!!

Okay, another query. Can I make my site which is wordpress scripted manually responsive?

I mean editing the code myself. Are there any good tutorials for that?

Ofcourse you can. Although it has to be okayed by your theme owner.

Try learning bootstrap. Its the simplest way to make your site responsive.
