this happens also with the latest nightlies but only when svg.enabled=true

Works for me... Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050601 Firefox/1.0+

I could be doing something wrong, but this doesn't work for me: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b2) Gecko/20050621 I've tried this with and without ./configure --disable-svg ... and then with and without svg.enabled Under no combinations have I witnessed designMode or svg working. I need designMode for work, so I fire up an old build for that... but I have to admit this bug is making me nervous. I'm picturing millions of firefoxes without a working designMode. :\

(In reply to comment #3) > I could be doing something wrong, but this doesn't work for me: I was doing something wrong - I'm not sure exactly what combination of ~/.mozconfig options I had that was spoiling things for me, but I've found a better config, based on the nightly builds. So, now, I have SVG /and/ designMode, and I feel like a giddy little futuristic cyborg that just got a semifirmware updage. Thanks to the Team

This is affecting Linux nightly snapshots (downloaded - 4 Aug 2005).

With Deer Park Alpha 2, no designmode (Rich-Text-Editor) is possible. see: http://www.kevinroth.com/rte/demo.htm even when svg is turned off or on, by using svg.enable (true/false) no effect.

Here's a test case, a simple HTML file with a designMode-enabled iframe that works fine in Firefox 1.0.x but fails with the following JS console error on today's nightly: Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMNSHTMLDocument.designMode]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: file:///home/myk/testcase-288747.html :: onload :: line 1" data: no]

I should note that I tested the testcase using a fresh profile. designMode is important functionality, and we shouldn't ship the beta with it broken.

Possibly related to bug 263392, bug 302885, and bug 256562.

Tor, Can you help us figure out who the right assignee is for this? Mike

just checked with last Firefox build 20050816 (Dear park), and it works fine again. SVG is also still working....

Confirmed. It now works for me again. This is probably a duplicate of bug 302885. Marking as such, but if anyone disagrees, then feel free to reopen and resolve worksforme instead. *** This bug has been marked as a duplicate of 302885 ***
