How to stop my firefox extension which interferes other extension?

Question

Hi,

I have tried very hard to make my extension as simple as possible, it now do not contain any skin/css, it just have 'statusbar' in one single 'overlay'.

The issue is that when installed, it hides the top three icon of 'all-in-one toolbar' extension of my firefox 3.6.3.

On other two machine which do not have 'all-in-one toolbar', it hide all the icons of the web-development toolbar!

chrome.manifest

content     stackoverflow    content/
content     stackoverflow    content/ contentaccessible=yes

overlay chrome://browser/content/browser.xul chrome://stackoverflow/content/browser.xul

locale  stackoverflow   en-US   locale/en-US/

browser.xul

<overlay id="dch-browser-overlay" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"&gt;
        <script type="application/x-javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"/&gt;
        <script src="stackoverflow.js" />

        <statusbar id="status-bar">
            <statusbarpanel id="stackoverflow-status-bar-icon" class="statusbarpanel-iconic" src="chrome://stackoverflow/content/icon_small.png" tooltiptext="&runstackoverflow;" onclick="stackoverflow.run()" />
        </statusbar>
</overlay>

I have tried very hard to simplify the extension to find the reason, but failed, any suggestion/ideas would be welcome.

thx.

Without seeing the code for the web developer toolbar, I'd say that it's the id on your overlay ("dch-browser-overlay") that is non-unique.

Side note: you really really shouldn't be loading jQuery from the web in the browser. Package it in your extension (in your case, it's going to slow startup down a bunch and present a security hole if you are MITMd).
