Firefox 16 disponível

A Fundação Mozilla anunciou a disponibilidade do Firefox 16.0, trazendo diversas correções de bugs e algumas novas funcionalidades, como o suporte a web apps.  Todas as novidades estão disponíveis nas notas de lançamento.



No entanto, devido a uma falha crítica de segurança, a havia Mozilla suspendido temporariamente a distribuição da nova versão, que voltou a ser disponibilizada, horas mais tarde, já com a correção efetuada, agora já através do Firefox 16.0.1., disponível -- como sempre -- para Linux, Mac e Windows.

Mac OSX: alternando entre abas do Chrome/Firefox/Safari

Outro dia expliquei como alternar entre janelas de um mesmo programa no Mac OS X.

Hoje vou explicar como alternar entre abas de um navegador de Internet, seja ele o Chrome, o Firefox ou o bom e velho Safari.




É muito simples.  O Chrome e o Firefox compartilham as mesmas combinações de teclas para esse atalho, qual seja:

command (⌘)+ option (alt) + seta direita (▶) ou esquerda (◀)


Ou seja, basta segurar as teclas command e option pressionadas e com as setas navegar entre as abas (tabs) adjacentes.


No Safari, para obter o mesmo efeito, basta acrescentar uma 3ª tecla:  shift.


Mas vamos supor que haja 7 abas abertas e você queria alternar entre a 3ª e a 7ª sem passar pelas demais. Neste caso, você pode utilizar o atalho que leva diretamente a uma aba específica, qual seja:


command (⌘)+ o número da aba correspondente


Desta forma, no exemplo acima, bastaria pressionar command e o número 3 e/ou 7 para ir diretamente à 3ª e 7ª aba, respectivamente. (não há correspondência no Safari).


Simples, não?

Firefox/Chrome - Security add-ons/extension - The essentials

So you just installed your preferred web browser, Mozilla's Firefox or Google Chrome -- it doesn't really matter --, what to do next?

Before you start surfing, you better get prepared, 'cause "it's a wild world out there!".  And with few add-ons/extensions that's pretty simple.

Nowadays, the Internet "is a criminals' preferred pathway for spreading malware", so why not use some easy tools increase your protection and help decide who's trustable?

WOT 
WOT is a award winning add-on, completely free, available to firefox and chorme, and downloaded more than 23 millions times, that "shows you which websites you can trust based on millions of users' experiences."  It adds a small circle next to the web address bar that like a traffic-light indicates if the site is trusted:

the greener the safer

reddish meaning the opposite

and yellowish the spectrum in between


Additionally, if the website you're about to enter has a really bad reputation, WOT will show a big warning and block the site.



And, of course, WOT is also a community you can make part of if you feel like sharing your opinion to help others and collaborate building the largest community driven World Wide Web reputation data-base.

Adblock for Chrome
Adblock Plus for Firefox

These two add-ons/extensions are originally intended to block the annoying publicity one finds all over the Wild Web.  But it can also be used to block links that distributes malwares -- just a matter of using the appropriate filter-list.

I've picked two different softwares on purpose, although Adblock Plus is actually available to either Chrome of Firefox indistinctly, while Adblock is available to both Chrome and Safari, but not to Firefox. Coincidently I happen to prefer Adblock Plus on Firefox and Adblock for Chrome, not only for this reason, but also because it was under this combination that the malware filter intended was easily installed.

So first thing's first: install Adblock/Adblock Plus into your webrowser (which won't be covered here, but is quite easy or at least easily findable). In Firefox will need to relaunch the browser (at least as of the time being this post is written under version 9.0.1) and on Chrome the installation of extensions doesn't require the relaunch of the application.

Once this is done, you might need to choose a publicity filter for your country/region or based on your language, but you can also skip this is you really enjoys publicity.

The installation process is also very easy and involves clicking on one link relative to the List of Malware Domains on this page or simply click directly on this subscription link and wait for the installation to begin.

A window should come up to let you know the subscription when throughout with no problem.
Additionally, you can check what lists you've subscribed to under the options of Adblock/Adblock Plus.

No further actions is required.  Adblock/Plus will automatically block your connections to the links that appears on the list you've subscribed to for their known relation with malware distribution.

There you are. Now you can surf the World Wild Web with security.

Adobe Flash server's garbage

By now, everyone should probably know Steve Job was right: Adobe Flash Player is garbage, not only because is has plenty of security holes, but also because is an inefficient way of making the CPU display videos.

And, yes, supposedly, they are trying to close the security holes, as every two weeks or so a new version is released.

But then, that leads us to realize that Adobe's servers entrust to provide the installers are also just a piece of garbage.

Yes, I'm upset, because I'm charged to keep the computers where I work safe, which means updated.  But if I don't use alternative download methods it is impossible to download the 14Mb installer via the on-line Flash installer, because it is damm slow and because the Flash installer will most certainly give a "download error" when progress is between 13%-26%.

The solution (#1 - if you want to keep Firefox with Flash enable) is to find alternative off-line installers and download it using download managers (such as DownThemAll) that could pause and resume the download process.

The other solution (#2 - Chorme) is to just uninstall any Flash from Firefox an rely solely on Chrome's auto update to brings you the last version of the Flash Player.  Which, of course, is not 100% sure, because that leaves on the user's hand the ability to install whatever version (and sourced) version of the Flash Player.
