From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.0rc1) Gecko/20020421 BuildID: 2002042108 Suggestion to display the ALT text for IMG as tooltip. There is also a minor problem that I don't know whether it is a feature or a bug. Say some tooltip text that has two lines or more, mozilla will display them in one line and truncate if it is too long. To Reproduce: <a href="any.html" title="Line 1 Line 2">Link</a> IE will display it as a multi-line tooltip while mozilla will display it as one line only.
The ALT-tag-as-tooltip part is bug 25537, marking DUPLICATE. Regarding multiline tooltips: the title attribute is of type CDATA. The HTML4 standard says about CDATA <http://www.w3.org/TR/REC-html40/types.html#type-cdata>: "User agents should interpret attribute values as follows: [...] * Ignore line feeds" Hence, this part of the bug is INVALID. Reporter, for future reference: only report one bug per report. *** This bug has been marked as a duplicate of 25537 ***
