From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461) BuildID: 2002053012 In order to prevent refreshing of a HTML page the following value was used to indicate not refresh was required, <meta http-equiv="refresh" content="-1" > IE, Netscape and Opera all take this to mean - don't refresh. Mozilla I believe takes this as refresh every second. It may be that a value of -1 is fairly illegal in terms of standards, and what should happen is that there should be no refresh meta tag if you don't want a refresh. A fairly reasonable point of view. Reproducible: Always Steps to Reproduce: 1. Create HTML page with meta tag, <meta http-equiv="refresh" content="-1" > 2. Load it - watch it refresh 3. Load it in IE, Netscape, Opera - watch it not refresh Actual Results: Page refreshes in Mozilla. Expected Results: Mozilla shouldn't have refreshed the page

-1 means "refresh one second ago", which is what we try to do in this case... jag, should we just treat a value smaller than 0 as meaning "no refresh header"? That's what IE and NS4 seem to do.... And yes, just not having a refresh header if you don't want a refresh would make sense, no? ;)

*** Bug 187672 has been marked as a duplicate of this bug. ***

given that meta refresh with a negative value isn't well defined by the standards, i'd vote for conforming to existing browsers.

If it makes Mozilla conformant, then I say we just ignore it. I'll submit a sample patch. Of course, the way to disable meta refresh is not to include it in the first place, or turn the tag into a comment. Stepping off into undocumented land of negative numbers isn't a good idea.

Simple patch ignores negative values.

Looks good to me.
