Has Ver 4 started checking ending HTML tags?

I left the > off a
tag and in Ver 3.6.x it is no problem. In Ver 4, 5 and 6, it is. In this case, it was the tag just before a <form> tab and the Submit button does not work.

Yes, if the HTML5 parser is enabled (pref html5.parser.enable) then a lot of such mistakes that didn't cause problems in Firefox 3 can now be causing problems.

You can usually see such minor mistakes if you inspect the page source code.

  • Firefox > Web Developer > Page Source
  • Tools > Web Developer > Page Source
  • Right-click on a web page to open the right-click context menu and select Page Source

Thanks cor-el. These are two things I didn't know about. I mean I knew about viewing the page source, but didn't know it shows bad tag construct. Too bad it doesn't alert for missing ending tags, eh?
