Firefox memory and processor consumption in Mac OSX

Firefox, one of my favorite browsers just fell under the category of fat memory and processor consuming beast on the Mac OSX. It is a sad fact, not using it much it can consume easily around 500 MB of memory, and pushing it just a bit makes the processor consumes anything from 10% to 90%.

I use Firefox and Chrome a lot for testing the applications that I”m building and I have always liked Firefox best since Firebug (one of Firefox best extensions) help’s considerably for troubleshooting anything from JS errors to HTML malformed and simple CSS changes.

It is truly sad, but between having my machine overheating and not using Firefox, not using it seems more of a logical decision.


Firefox Skin – Personas

I was pretty bored yesterday night so I decide to mess up with the Firefox Personas (or themes, skins, etc). Following the instructions, with a little effort, I could manage to create one and using the Personas Plus it as easy to test.

Choose an image, created the theme, submitted to Mozilla and after an excruciating 24 hours period, it got approved (yeay).

Check it out and, hey, why not, activate it on your Firefox 😀

Context menu disable with JQuery

I have found a ton of tutorials teaching how to disable the context menu on browsers and in all of them I have found one flaw:

Does not work with Opera

It’s an anoying situation that got me thinking and searching for a solution through most part of the day and with no luck.

The function is simple:

$(document).bind(“contextmenu”, function(e)
return false;

and it works with (tested):

and it does not work with (tested)

After a lot of research I have found why it does not work with Opera:

Opera (9.5) has an option to allow scripts to detect right-clicks, but it is disabled by default. Furthermore, Opera still doesn’t allow JavaScript to disable the browser’s default context menu which causes a usability conflict.

You can try to disable by disabling the mousedown event filtering only for Opera, but I do suggest a lot testing on this.

To complete just an extra note: this function does not bind the documents inside an iframe, so in this case you should complete the function by disabling the context menu in the iframe document as well.

Fine tune your Firefox

This video from show some great tips and tricks to fine tune your Firefox. It’s already not fair for the other browsers to know that Firefox is already the faster browser, and with some fine tunning, it feels like a jet.

Javascript LIbrary Detector

I was scooping out a blog from a friend of mine today, Smooka Blog, and I found this interesting post from a Firefox plugin for detecting Javascript libraries. It’s useful in many ways since you can learn if your project have correctly loaded the library or what library does the site that you are visiting have.

Anyway, cool post, check it out: http://www.smooka.com/blog/2009/03/26/javascript-library-detector/#more-52

Microsoft Releases IE 8 Today

According to the Wall Street Journal, Microsoft will release today, at noon, EDT the new IE 8 (link to IE8 beta page – will update when the new one comes).

This will give Microsoft a slightly advantage over it’s principal competitor Firefox 3.5.

As any web developer I’m not as much excited as any user should be, since this will be one more IE to test web applications (IE 6 and 7 still up  :[ ).

Let’s now wait for the new IE and see how it will handle on Vista and XP.
