From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461) BuildID: 20011112009 In Composer select the HTML source tab which displays the source of the web page. Place the cursor at any point in the document and press the TAB key any number of times. The source is not indented nor is there any change in the document source at all. Earlier builds (0.9.5) would generate non-breaking space characters in the source which only became visible in the source view after switching to one of the other 3 views and then switching back to the source view. This does not appear to be the case in 0.9.6 but perhaps it will help in tracking down the source of this problem. Reproducible: Always Steps to Reproduce: 1. Open an instance of the mozilla composer 2. Select the HTML source view 3. Place your cursor at any point inside the HTML source 4. Press the TAB key a few times Actual Results: No change to source formatting Expected Results: Source is indented at the location of the cursor each time the tab key is pressed.
