Can we use firebug extension to fix User Interface of web pages on new Mozilla firefox 3?
How to install firebug on Mozilla firefox 3 beta 5?
And etc.

Answers are,

Yes, you can use firebug extension even though it has not yet come up with its version for Mozilla Firefox 3.
Steps to install firebug for Mozilla Firefox:

1) Type the following link on your IE browser address bar https://addons.mozilla.org/en-US/firefox/search?q=firebug&cat=all
Note: If you use mozilla firefox 3 latest version to download the extension you will see a text saying "This add-on is for older versions of Firefox" because its made for this latest version.

2) So use ie browser click download button from the above linked page to download firebug-1.05-fx+fl.xpi and save it to your local hard disc.

3) Change firebug-1.05-fx+fl.xpi to firebug-1.05-fx+fl.zip to open the zip file.

4) Open install.rdf file by double clicking on it (notepad may open) and now you can change the browser version 2.0.0 to 3.0.0 after from the rdf file code as mentioned below,
Replace the code and save
from "<em:maxVersion>2.0.0.*</em:maxVersion>" to "<em:maxVersion>3.0.0.*</em:maxVersion>"

- Codes depict the maximum support by firebug extension for Mozilla Firfox browser.

5) Change firebug-1.05-fx+fl.zip file extension to firebug-1.05-fx+fl.xpi and copy it to your local hard disc. Example path: C:\Program Files\Mozilla Firefox\extensions.

That's it you are done with it. You have got that working extension for your new Mozill Firefox 3 browser.
Now just close your firefox 3 browser and reopen the browser. You will get Add on browser pop-up window to install that firebug xpi file as add-on to your browser.

I hope your font end development will deserve super success. All best.
Any comments? Please do reply to the post.

The novel approach is about get a additional CPU Box which will have Firefox 3 and IE 8 installed and could be connected by RDP (Remote Desktop) from your main CPU Box. The Main CPU box could have some older version of firefox and ie browsers. By sharing /hosting developing web pages, we could test and develop pages with RDP connection.
I hope this approach could be more useful than my first post about an approach to develop and test pages for multiple IE and Firefox browser version.

All new coming posts will be related to UI fixes and workarounds for IE 8 and Firefox 3 till every one gets hands on with these latest browsers behaviors.

<Reply to Rafi Ali Khan’s Comments: I will have posts detailed with snapshots when it’s required to make the context clear as per your advice. Thanks.>

To work on all the browsers like IE6, IE7, IE8 Beta1, Firefox 1.5, Firefox 2.0.1, Firefox 3 beta 4 you will need one more CPU box along with your existing. Using a controller you can switch two CPUs on your single monitor to develop pages for your entire browsers by installing IE6, IE7, IE8 Beta1 and Firefox 1.5 to a CPU and Firefox 3 beta 4 with the other one.

This is my approach...If you have any other approach do reply to this post, that would be appreciated. Thanks.

1. Default Themes - Firefox has never been known for having a particularly appealing default theme. While it has gotten the job done, it certainly hasn't been anything to brag about. However, this hasn't really been an issue, since there are hundreds of third-party themes that can be installed for the browser. However, for Firefox 3, Mozilla has decided to take a change of pace and offer users something a little more appealing. What this means is that Windows users will get a theme that has a Vista-like user interface, Mac users will get a Mac-like user interface and Linux users will get a Linux-like user interface. I am currently using the Mac version of Firefox 3 and actually find the user interface to be much more appealing than Safari's. Firefox 3 utilizes common grey scheme of Mac applications to great effect, creating a very elegant user experience.
2. Bookmarking - Thanks to Firefox 3, bookmarking is easier than ever. Now, all you have to do to bookmark a site is click on a small star outline located on the right side of the address bar. Clicking this will cause the star to fill in, which indicates that the site is now bookmarked. By double-clicking the star, you can specify the name of the bookmark, the location of the bookmark and, new to Firefox 3, tags you would like the bookmark to be associated with.
3. Add-ons - Firefox 3 has revamped its Add-on menu, allowing you to easily manage all of your extensions and themes, and even download recommended add-ons right from the menu itself.
4. Downloads - Firefox's download manager has also been greatly improved, with perhaps the best new feature being the ability to pause and resume downloads, even between multiple Firefox sessions. Another neat feature is the ability to see your download progress in the status bar.
5. One-click site info - In terms of security, Firefox 3 is leaps and bounds above Firefox 2. One useful new feature is the ability to get detailed information about the site you are on, such as who owns it, if it is encrypted and if the site is storing cookies on your computer.

Overall, I must say that my experiences with Firefox 3 Beta 4 have been very positive. From its elegant new look to its increased usability, Firefox 3 definitely seems as though it will be a winner when the final version is released later this year. Nevertheless, although I have been very pleased with Firefox 3 Beta 4, I have still encountered my fair share of kinks, as is to be expected with beta software. Although the new add-ons menu is supposed to make managing and installing add-ons easier, I have found that sometimes Firefox will not allow me to install updates for various components, such as the the Proto Firefox theme. There have also been several instances where Firefox randomly crashes. Although these crashes may be a nuisance, they are usually not particularly harmful thanks to Firefox's handy Session Restore feature.

Due to the recency of Firefox 3 Beta 4's release, most of my favorite extensions are not yet compatible, although, this is of course no fault of Firefox itself. The extensions that do work, such as Google Notebook, work very well and I have encountered no problems with them. While it is hard to go without my favorite extensions, such as Sage, the new features of Firefox 3 more than make up for the loss.

Despite a few blemishes (and there really are just a few), Firefox 3 excels in almost every way and I am greatly looking forward to reviewing the final version come this summer.

What I found the difference between the previous version and this one (though most of the features are much the same) is the smart bookmarks folder which stores our bookmarks according to our preferences and a star is provided with in the address bar for easily bookmark.

All the sites that I've opened have well worked fine and there ain't a case of broken website and guess there won't be one.

You can just get your hand on to this new version here....

Tristan Nitot, presidente europeo de Mozilla escribe un interesante post sobre la drástica reducción de memoria en la última Beta de Firefox 3.

Nitot hace referencia al blog de un ingeniero de Mozilla, Stuart Parmenter, donde explica con detalle el trabajo realizado para minimizar el consumo de memoria.

El siguiente gráfico muestra una de las pruebas que han realizado cargado en Firefox 2, IE 7 y Firefox Beta 4 hasta 319 paginas web automáticamente, una vez cargadas, se cerraron todas y tan sólo se dejo una abierta. La conclusión del experimento se puede observar en el gráfico.

900 περίπου είναι οι διορθώσεις στην τέταρτη δοκιμαστική έκδοση (beta 4) του Firefox 3, ο οποίος κυκλοφόρησε λίγες μέρες μετά την beta του ΙΕ8.

Ο "πόλεμος" των browsers έχει μεταφερθεί σε "δοκιμαστικό" επίπεδο, μιας και οι beta εκδόσεις ανακοινώνονται και κυκλοφορούν η μία μετά την άλλη. Προχτές κυκλοφόρησε o Firefox 3 beta 4, που περιλαμβάνει 900 βελτιώσεις από την προηγούμενη δοκιμαστική έκδοση, σε τομείς όπως η διαχείριση μνήμης, οι επιδόσεις, η σταθερότητα και άλλα.

Στον ευαίσθητο τομέα της ασφάλειας, ο Firefox 3 έχει προσθέσει προστασία απέναντι σε κακόβουλο λογισμικό, spyware, Trojan και ιούς. Επιπλέον, αποτρέπει την πρόσβαση σε γνωστά παράνομα και κυρίως επικίνδυνα sites, ενώ συνεργάζεται άψογα με τα εργαλεία γονικών ελέγχων που είναι ενσωματωμένα στα Windows Vista.

Όσον αφορά στις επιδόσεις, ο Firefox 3 έχει βελτιωμένη μηχανή Javascript η οποία επιτρέπει στις web-based εφαρμογές να εκτελούνται ταχύτερα, καλύτερη διαχείριση μνήμης ώστε να καταναλώνει λιγότερη από τον υπολογιστή μας, ενώ έχει γίνει πολύ πιο ασφαλής η βάση δεδομένων στην οποία διατηρούνται οι ρυθμίσεις του browser, τα bookmarks, το ιστορικό επισκέψεων σε ιστοσελίδες (history), τα cookies και οι γενικότερες προτιμήσεις μας για την λειτουργία του Firefox.

FireFox 3 Beta 4 

Días atras les contaba como se venia el beta 4 de Firefox con respecto a las velocidades de acceso.

Por lo mismo, para todos aquellos que les gusta ir a la última o tan solo saber como va evolucionando el zorro panda de fuego, les traigo listo para descargar la última beta conocida de Firefox 3, el beta 4.

Está disponible en español desde el FTP de Mozilla.

Disponibles en versiones para Windows y Linux.

Todas estas betas son las que han mostrado en las Nightly Party o cuando se juntan todos los desarrolladores a tomar unos tragos y pasarlo bien con unas cuantas mujeres hablar del navegador.

Recuerden que la versión de Firefox 3 aún no ve la luz y seguiremos testeando estos betas mientras eso no pase.

Si intrusean un poco más en el FTP entenderán por qué digo la última beta conocida...
