The "What's Related" sidebar has a capability I'd like to build into a new sidebar. I want to automatically update the content of my sidebar when the URL of the main window changes. The best solution would be to use javascript and XPConnect, but I can see how that could be a security Pandora's box. If not, what would you suggest? Thanks, Robert Cook ------------------------ I'm copying a post from last year that asks a similar question which received no responses: From: Matt Martel <[EMAIL PROTECTED]> Subject: Sidebars and XPConnect Date: 2000/05/12 Message-ID: <[EMAIL PROTECTED]>#1/1 Content-Transfer-Encoding: 7bit Organization: Another Netscape Collabra Server User X-Accept-Language: en Content-Type: text/plain; charset=us-ascii; format=flowed User-Agent: Mozilla/5.0 (Windows; N; WinNT4.0; en-US; m14) Netscape6/6.0b1 Mime-Version: 1.0 Newsgroups: netscape.public.dev.mysidebar,netscape.public.mozilla.xpcom I am trying to use the observer service in my sidebar page code. This mimics the "What's Related" functionality, in that it wants to be notified when the browser navigates to a new location. I've even borrowed some of the related-panel.js code, with some success. Until recently I could bypass the XPConnect security issue by setting security.checkxpconnect to false in prefs.js. Now this no longer works, and I cannot successfully enable the UniversalXPConnect privelege within my sidebar javascript code. I guess the real question is, how does this work for the "What's Related" code? I don't see anything special to allow related-panel.js to access the observer service. Any info would be appreciated. -- Matt Martel [EMAIL PROTECTED]
