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.

Understanding The Linux Kernel's BPF In-Kernel Virtual Machine

BPF continues marching forward as a universal, in-kernel virtual machine for the Linux kernel. The Berkeley Packet Filter was originally designed for network packet filtering but has since been extended as eBPF to support other non-network subsystems via the bpf syscall. Here's some more details on this in-kernel virtual machine. Alexei Starovoitov presented at last month's Linux Foundation Collaboration Summit in Santa Rosa about BPF as an in-kernel virtual machine. The slides have been published for those wishing to learn more about its state and capabilities. Read more
