I can verify that a bookmarks.html file shows folder levels "tabbed" over to the right in Firefox 3.6.x and doesn't do the same in Firefox 4.0.

!DOCTYPE NETSCAPE-Bookmark-file-1> is not a valid HTML file and was never meant to be displayed as a webpage, it is displayed in the Quirks Mode by web browsers. This file format was used by Netscape, Mozilla, and few other browser maker's as a storage file for bookmarks and is the interchange format for importing and exporting bookmarks / favorites between most all brands of browsers for the last 15 or 16 years.

The "tags" used in the Netscape bookmarks.html file for "folder" structure - DT, DD, & DL aren't valid HTML code used on webpages and I guess Gecko 2.0 doesn't "guess" the same as Gecko 1.9.2 and earlier did. There's a whole bunch of other data in the Netscape bookmarks.html file that Firefox has always ignored when displayed as a web page because it wasn't "valid code". Firefox 4.0 seems to be ignoring the folder structure tags now.

Sorry, I can't think of a way to overcome this change, short of writing a script to change all those "tags" to proper HTML tags and running that script after you export the bookmarks.html file from Firefox. Cor-el might have some script ideas, if he sees this thread.

I see in the DOM Inspector that Firefox 4 places the content if the DT container. Firefox 3 acts differently and can use DL > DL to get the indent.

This bookmarklet seems to work to get the indent again:

javascript:(function(){var d=document,sS=('dl > dt > dl { margin-left: 40px; }'),nS=d.createElement('STYLE');nS.setAttribute('type','text/css');nS.innerHTML=unescape(sS);d.getElementsByTagName('head')[0].appendChild(nS);})();

Cor-el - is there a way that can be added to the bookmarks.html file, instead of having to click on a bookmarklet each time the page is opened?

edmeister, cor-el: Thanks for your input.

cor-el's bookmarklet script works, though, as edmeister points out, it is a bit inconvenient.

I am thinking that a wrapper for the bookmarks.html file might work. The wrapper (say, wrapper.html or wrapper.js) could load the bookmarks.html file and then run the equivalent of cor-el's bookmarklet. The wrapper file would then become my "home page".

Unfortunately, I am not an expert with HTML of JS, although I have done some very simple stuff with them. (Over the years, I have done a lot of programming in other languages.)

Any advice on how to create such a wrapper would be much appreciated. An example would be even better.

My own attempts to do this have not been successful. I suspect that the wrapper execution stops as soon as bookmarks.html is told to start. That would actually make sense. Otherwise, generally, this approach could open some serious security concerns.

Thanks.

Okay, I found a simple way to make this happen.

1) I created a file called bookmarksAddendum.html and filled it with a re-formatted version of cor-el's bookmarklet script:

<script type="text/javascript">

 var d=document;
 var sS=('dl > dt > dl { margin-left: 40px; }');
 var nS=d.createElement('STYLE');
 nS.setAttribute('type','text/css');
 nS.innerHTML=unescape(sS);
 d.getElementsByTagName('head')[0].appendChild(nS);

</script>

2) I created a Windows command script called bookmarksAddendum.cmd and filled it with the following to append the bookmarksAddendum.html file to the bookmarks.html file:

COPY bookmarks.html + bookmarksAddendum.html bookmarks.html

EXIT

3) After running the bookmarksAddendum.cmd file, the bookmarks.html file is rendered with subfolder indentations in Firefox 4.

This works even if the .cmd file is run more than once.

It would be nice if there were a simpler way to get the same result. Ideally, the Gecko engine would handle this natively.

You can add this CSS code to the HTML file below the line with the meta tag or use the copy method posted above by stormseye

<style type="text/css" >
dl > dt > dl {
 margin-left: 40px;
}
</style>

Thanks cor-el. That is a simpler, more concise solution and I am now using it in my bookmarksAddendum.html file.

I have also changed my bookmarksAddendum.cmd file to use the following instead of the COPY command:

TYPE bookmarksAddendum.html >> bookmarks.html
