The first part is make sure your browser.display.show_image_placeholders variable is set to true in your config file. To do this type about:config in the address bar of the browser, hit enter, and then do a search for this variable. A double click will change the value of the variable.

If you still can’t see the icon despite the fact that browser.display.show_image_placeholders is set to true then you need to follow this steps:

• Go to the Firefox profile folder.
• Go into the user folder found there.
• Go into the chrome. folder
• Duplicate the file userContent-example.css and save it as userContent.css
• Open a text editor and paste the following code:

  /*
   * Show image placeholders
   */
  @-moz-document url-prefix(http), url-prefix(file) {
    img:-moz-broken{
      -moz-force-broken-image-icon:1;
      width:24px;
      height:24px;
    }
  }
  

• Save the file and restart Firefox

On Mac Os X the path to the css file would look something like this:
/Users//Library/Application\ Support/Firefox/Profiles/ /chrome/userContent-example.css

I hope this had solved your problem.

Everything that make our life easier is always welcome, that’s why I have created this page. I pretend to collect some of all those “Tips, Tricks, and Applications” that I used to make my work journey

Applications

• Coda is more than a text editor and is the second most used application in my computer (is difficult to beat browser’s first position)
• Dockables: With a simple click of your mouse you can lock your screen, backup your time machine, go to sleep mode, and more…

Tips & Tricks

• Here is a nice collectios of Tips & Tricks for Coda.
• A very handy jQuery Plugins list.

We all know that when you want to add multiple files to the SVN repository you need to specified each one of those files, something like this:

svn add file1 file2 dir3/file3

But what happen when what you need is to add all those files that are not under revision yet?

Well, in that case we have this solutions:

svn add $( svn st | grep "^?" | awk '{print $2}' )

I hope this make a little bit easier your working days.

Update: I have found this other option that is shorter and easier to remember.

svn add * --force
