Windchill 11 and Firefox 59

[JonathanHodgson]

Has anyone else had problems with the recent Firefox 59 update?

I've been using Windchill 11 (11.0 M030 CPS07) via Firefox without problems up to the end of last week.  Yesterday morning (after my initial log-in), Firefox updated to 59 and some time after that Windchill stopped accepting my credentials (across multiple platforms), and I and our IT team have been chasing the problem for about the past working day.  Through multiple trials this morning, it seems that once my account is unlocked (again!) I can access it through IE, and through the embedded IE in Creo, but not in Firefox any more.

Known issue, or should I flag it more formally (if others can corroborate)?

I just tried Firefox 59 with Windchill 11.0 M030 CPS04.  No issues.

I've got Firefox 54 and going to do my best to hold off on updates until there's more discussion.  We did just update to CPS08 and that seemed to fix some Java problems.  I wonder if it could help you?

The latest Firefox build (59) introduced a series of issues.  Note that it is not formally supported - only the Firefox ESR releases are supported.  The current ESR is 52 with the Firefox ESR 60 coming out this may.

I know the Quantum releases are faster so I can imagine people are anxious to use them.

Thanks Jeff.  I've switched back to using IE just for Windchill (with Firefox as my default browser) but our Windchill guys weren't aware that current releases of FF aren't supported, so that's useful to know.

Jeff,

I wonder what is the best way to keep up with the changing Platform support matrix?
