Saving in Firefox

Suddenly, trying to save a file or a page in Firefox (v 1.7.12, SUSE 10.0) I'm getting an error. It only began happening in the last three or four days. The error I get is "XML Parsing Error: syntax error". The location of the error is different depending up which type of file I'm trying to save. Additonally, sometimes the file gets saved (even while outputing the error) and sometimes it doesn't. Is anyone else encountering this? -- Marshall Lake -- mlake@mlake.net -- http://mlake.net
