My site, http://www.staratlas.com , makes heavy use of CSS. If you browse this page, choose "News Archive" from the list of links at the left, then choose "March" from the center list of links, then use the back button and forward buttons to move backwards and forward through the site hierarchy, sometimes pages have CSS applied, sometimes not. It is most easily visible by observing fonts as Mozilla's default is to apply serif fonts, but the CSS calls for sans-serif. Which page fails to parse CSS is completely random from one reload to another. This is build #2000022414. The Bug Entry page seems to think this browser is M13, but it's a nightly build of M14.

Changing to Style System. Pierre, I remember seeing a checkin (yesterday maybe) that looked like it was related to this. Do you think that change may have fixed this?

Note that the bug is still present in Build 2000030813.

This bug was fixed yesterday, the fix will appear in today's build. If you are using a previous build, the workaround is to turn off the Memory Cache in the Debug prefs. Closed as dup of 29370. *** This bug has been marked as a duplicate of 29370 ***

Marking as verified duplicate.
