Issue parsing XML

When retrieving an XML over HTTPS (like a WSDL for my case), it appends the CSS of the extension. (.ui-widget-overlay{ z-index:0!important; })
I believe an option should be there to exclude or not different content/type such as text/xml in my case.
BTW, thanks for this extension.

The extension's own css rules are getting overridden by website css rules

Let's take ".ucss-opacity input[type="range"]" for example. Now, if I have some css rule in my website, like -

input[type="range"] {
min-height: 40px;

This rule is also getting applied to ".ucss-opacity input[type="range"]", affecting how the extension looks. Maybe it would be better to just add !important to all the extension's css rules.

The plugin no longer works. Throws error: Uncaught ReferenceError: jQuery is not defined

I'm guessing that my company has locked down my browser further and is the root cause for this, but just in case i thought I'd float this past you.

When I click the icon to get the tray to slide out I get this message in console:
VM362 scripts.js:315 Uncaught ReferenceError: jQuery is not defined
at VM362 scripts.js:315:4

If there is anything I can do please let me know. I really depended on this plugin to fix some CMS things that irritated me and made it much more user friendly.

Works on Chrome, but not on Edge (Chromium)

Hi seems the "flyout' doesn't appear in Edge (Chrome version) when i click "CSS". Are there any plans to make this work on Edge?

Plugin not working - jQuery not loaded!

Seems the Plugin doesn't work anymore. Sidebar not opening on icon-click. Adding a CSS-rule in the Plugin settings also does nothing anymore. And in the Inspector i get the error message, that jQuery is not loaded. I guess that's the cause of all the problems.

Won't load

Clicking on the icon no longer works for me - just nothing happens.
It does still work on any sites where I added CSS - the inserted CSS is working.
But the config window doesn't open so I can't add/change any of my CSS.

how does it work???

There's zero documentation, which means it should be intuitive, but it's not. Am I missing something - where are the instructions on how to use this extension? I've gone to a website and it says User CSS can change the site's data. OK, now what? There's nowhere to add CSS. Clicking the icon does nothing. There's nothing under Options > Styles when I enter the site's url.
