My Favorite Firefox Extensions

The Firefox web browser supports hundreds of extensions in its latest version. There are extensions that tweak its behavior in small but useful ways, addons that add completely new and very innovative features, even entire applications like FTP clients and e-mail posting programs that run inside the browser.

It would be silly to list all the extensions supported by Firefox here. There are some extensions, however, which I consider vastly more useful than all the others. These are usually the first things I add to every new Firefox installation before using it for browsing web pages. Continue reading

Stalking Keramida

Quick tip for finding if keramida’s been active in a machine the last few days.

Mercurial command demo: hg verify

One of the wonderful commands that Mercurial support is the “verify” command. Running this command in a Mercurial workspace goes through the backing store of the repository and makes sure that the history and contents of the versioned files are not corrupt, missing or otherwise in a “bad” state.

An example of how you can use this Mercurial command is described here. Continue reading
