You are using an incompatible web browser, Facebook said

facebook-browsers

I almost have no problems accessing Facebook site using many different browsers. But, I sometime I found problems when using Opera 10 browser. It says that I’m using incompatible web browser. But, it only happens randomly, even when I do the same actions like reloading pages, clicking on the links. And so far, it only happens on Facebook-related pages.

The error page suggests me to use these browsers: Mozilla Firefox, Opera, Safari, Microsoft Internet Explorer, and Flock. I do using Opera, but not the latest stable release. So, is it Facebook? Or, Opera 10 doesn’t play nice with Facebook yet? I’m using Opera Version 10.00 1 Build 1355 on Windows XP when I experience this problem.

Zeldman on IE 6

IE6 is the new Netscape 4. The hacks needed to support IE6 are increasingly viewed as excess freight. Like Netscape 4 in 2000, IE6 is perceived to be holding back the web.

Pushup: Encourage others to upgrade their browsers

I just added some Javascript file and CSS in this blog. You probably will notice them, or not. You will not see something different in this page if you’re using an updated internet browser. But, if you’re still using old browsers, you should see a notification — it’s on the upper right of the browser window — telling you about your browser status (updated or outdated).
Pushup : Pushing up the web
Anyway, I got this from Pushup campaign.

Pushup is an effort to push the web forward by helping users upgrade their outdated browsers. Give your users a better web experience today by installing Pushup on your domain! A subtle upgrade link is shown when people visit your website using an outdated browser. They can click this link to visit the upgrade website for that browser, or choose to be reminded after a time you specify.

The installation (adding Javascript and CSS) is easy. Go to Pushup website, and you will get everything you need to get it installed in your website/blog. Demo is also available there. Anyway, remember Browse Happy?
