Master Firefox's Hidden Configuration Tools

Filed under
Moz/FF

I often write that the Mozilla Foundation's Firefox browser does thus and such, or doesn't do this or that other thing. What I mean is that the program has no menu command or preferences dialog box to give users control over its cache, performance, and other settings. In truth, there are other handy but hard-to-discover ways of configuring Firefox to behave according to your wishes.

Firefox inherits a number of hidden configuration interfaces from its Netscape ancestors, namely its 'about:' URIs (Uniform Resource Identifiers). For instance, in last April's Internet Tips column (under "Clear the Cache"), I wrote that unlike Internet Explorer, Firefox doesn't allow you to view the contents of its cached Web pages and related files. While it is true that you won't find a menu command or setting in the program's interface for that task, reader Fran Snyder, who contacted me via e-mail, notes that all you have to do is type about:cache into Firefox's address field and press to view links to the contents of the browser's memory and disk caches.

So why would you ever want to peruse your Web browser's cache?

Full Story.

Hands on with Caine Linux: Pentesting and UEFI compatible

Caine 6.0 is derived from Ubuntu 14.04.1 (64 bit). That is a Long Term Support release, so that is a good thing. It uses the MATE desktop, rather than Unity, which is another really good thing. The ISO image can be obtained from their Downloads page (duh), and is relatively large (2.68GB). Read more

Linux Mint 17.1 finally makes MATE's fancy Compiz graphics easy to use

Linux Mint isn’t chasing touch interfaces, rethinking the way we use the desktop, or enacting any other grand experiment. It’s just a polished, modern Linux desktop system—and that’s why people love it. Linux Mint 17.1 (codenamed “Rebecca”) is on the brink of being released, and it continues the Linux Mint mission of refining the interface we use every day. Read more

Imp mini PC is a tiny, ARM-based Ubuntu computer

Want a small, low-power desktop computer that runs Ubuntu Linux, but don’t want to go through the hassle of installing and configuring the operating system yourself? Read more

Ubuntu MATE is a heavyweight among the lightweight distributions

What kind of operating system would you run on your PC? One that hogs resources leaving you with just enough to do your work or one that ‘glides’ over the resources leaving almost everything for you to use? I would certainly choose the latter. And if I ran a business, where a penny saved is a penny earned, I would be even more conservative about it. I use Arch Linux with KDE Plasma on my main machine. This combination gives me a fully optimized base OS with a desktop environment (DE) that is known for being the most feature-rich. However, I am always on the lookout for a DE that can run efficiently on less-powerful (aka less expensive) hardware, with an easy to manage OS. Read more
