Firefox extension error “… does not provide secure updates”

When trying to install the newest version of the ProxyButton extension for Firefox, I received this error:

Screen capture: Firefox "secure updates" extension error

Incompatible Extension

“ProxyButton” will not be installed because it does not provide secure updates

Luckily a solution exists over at Idea Shower. Add a new boolean key using about:config and restart. Easy-peasy. More at Idea Shower.

Using a Mac .dfont on Windows

Update 2011-09-03: There appears to be a free GUI app available, DfontSplitter. And hey, it’s even cross-platform (Win & Mac)! I have no personal experience with it, so downloader beware. Thanks to Matt T. in the comments.

I was able to use a Mac OS X “.dfont” font file on windows by using a simple FOSS software to convert it into standard TrueType format (.ttf). The app is called Fondu. It’s actually a set of many command line programs rolled into one, but I only used the main fondu app. Couldn’t have been easier:

Update 2009-10-14: To clarify, these instructions are for Mac OS X. I do not have any info on running fondu from windows (if that is even possible. I suspect it isn’t). Perhaps windows users could run fondu on a linux virtual machine/box they have lying around? Maybe a linux live CD?

  1. Download & Install .pkg file
  2. From Terminal, cd into the directory where the .dfont file lives
  3. Run fondu MyFont.dfont
  4. Marvel as a .ttf font is spit out next to your .dfont file

Thanks Fondu!

Update 2009-05-22: Please note that the fondu binary lives in “/usr/local/bin/” by default. Either add this path to your environment, or prepend the path to the fondu command like this: /usr/local/bin/fondu MyFont.dfont

Subscriptions in NetNewsWire change color

I had no idea why some of my subscriptions in NNW were a light tan/brown color. See here how “RateMyTeachers.com” and “sportsbbq” are brown:

Turns out that the subscriptions change to that color for feeds that have not updated (added a new post) in 60 days. Perhaps I’m just dense, but this was not obvious to me.

Anyway, if you care to change that color, go to: Preferences -> Fonts -> General -> Show Color Options...
