Saving webcam images from a website?!

Saving webcam images from a website to do kiln logging, using a bash script on your Mac (or other UNIX based systems).

Firefox zoom not working on Mac OSX

By default the “pinch open” and “close zoom” options are not working in Firefox on OSX. But it’s not that hard to enable the Firefox zoom settings, if you know how to do it…

Open Firefox
Go to a new tab, type in “about:config” and hit <Enter>.
Click the “I’ll be careful, I promise!” button.

You can now modify the related browser.gesture preferences by changing the values as stated below:

  • -> cmd_fullZoomReduce
  • -> cmd_fullZoomReset
  • browser.gesture.pinch.out -> cmd_fullZoomEnlarge
  • browser.gesture.pinch.out.shift -> cmd_fullZoomReset
  • browser.gesture.pinch.latched -> false

Once you have changed the preferences, close the tab and the new settings should work. You might want to restart Firefox!?
