Web Development Browser Extensions

Now a days browser vendors are competing with each other on who has the most and fastest version update. With CSS now a standard technique, the competition is also on on who supports the most selectors and uses the best syntax. Have you seen the gradient syntax? Safari 4 really made an art of it, luckily they came to their senses in Safari 5.1:

/* Firefox 3.6+ */
background-image: -moz-linear-gradient(#2F2727, #1a82f7);

/* Safari 4+, Chrome 1+ */
background-image: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#1a82f7), to(#2F2727));

/* Safari 5.1+, Chrome 10+ */
background-image: -webkit-linear-gradient(#2F2727, #1a82f7);

/* Opera 11.10+ */
background-image: -o-linear-gradient(#2F2727, #1a82f7);

Code by CSS Tricks

Now that CSS has become so extensive and fully implemented, web browsers extensions are unmissable if you regularly work with HTML and CSS. Extensions have become a standard in most developers their browsers, that there are even more niche ones like for JSON, jQuery and SQLite.

I collected the most used web developer extensions for all 5 main browsers. I’m not an Opera or Internet Explorer user, so I might have missed a good one. Firefox is my main browser and Chrome secondary. I don’t use Safari either, only for testing. I would love to make Chrome my main browser, but I can’t find a nice theme for it, like GrApple which I use with Firefox.

Whether you work with code everyday or not, these extensions are a must in your browser, they’ll save you some headache along the way.

    Nice post. I actually don’t use any extensions at all, don’t really know why! Guess I just can’t be bothered keeping them up to date and I have a constant fear of unneccessarily slowing down my browsing.

    I get by ok though! :)
