Question

Keep in mind that I’m not looking for a list of current browsers to support, I’m looking for logical ways to make that list, backed by some kind of hard statistics.

Since it’s been a while since my last web job, I decided to do this latest site up from scratch. Now I have to decide again what to support in terms of browsers. Certainly I have a list of what I’d like to support, but the decisions that went into that list seem to be a little arbitrary to me. Where can I go to get a reliable picture of browser usage and what seems to be a good point at which to cut off an old version of a browser from support?

Answer 1

Browsers don’t die out completely for about a decade. The first thing you must realise is that you will have some visitors that are using a browser you don’t support. The question is not which browsers are not dead, but which browsers are worth supporting (the benefit) relative to the work it takes to do so (the cost).

I’ve never seen browser statistics I’m comfortable recommending, they all seem to be snake oil. A rule of thumb I feel is appropriate is that a browser isn’t worth supporting if somebody using that browser is going to regularly run into problems on other websites as well. In other words ‘stick with what everybody else is supporting’. To that end, Yahoo’s graded browser support is useful.

Ultimately, the best choice depends on your individual circumstances and will change over time. For instance, 37signals have recently dropped support for Internet Explorer 6 and Facebook are slowly heading in the same direction. This isn’t a decision that most organisations can make yet, but give it a year or two and you’ll see a lot more organisations follow suit. Right now, it’s a bold step that you probably can’t justify, but give it time.

Don’t fall into the trap of thinking that supporting as many browsers as possible is automatically the best choice – it may be that you are doing your visitors a disservice by wasting time working on compatibility with a browser used by five people when you could be improving the experience for the other million users you have.

Also, it’s worth considering that you can ‘officially’ not support a browser. For example, one thing I’ve done in the past is use JavaScript served only to Internet Explorer 5.5 and below (via a conditional comment), to automatically remove stylesheets, JavaScript and replace images with their alt text. Without those measures, the site would be unreadable due to Internet Explorer’s many layout bugs, but with it, the site at least works, even if it’s too much work to ‘support’ it.
