JS: Create new unique instance of my plugin

I have created a JavaScript plugin, I'd like to have the potential to use this multiple times, however, having it called one the page twice like follows doesn't seem to make a new instance:
var lightbox = new MarvLightbox({
imagesContainer: 'detail-hdr__detail-images',
limit: 11
});
var lightbox2 = new MarvLightbox({
imagesContainer: 'image-grid-2',
galleryFolder: 2,
mobileFolder: 0
});
The following code seems to be returning the same values, so for example, if I click an image to set the c value within the state object then it's changed for instance lightbox2 AND lightbox.
MarvLightbox.prototype.current = function() {
console.log(state);
};
I have tried to remove any none required code from my plugin. But what I'm basically doing is:
1. Compile a list of the images within a container.
2. Generate HTML from a JSON string.
3. Assigning click events to the images, and then when clicked they open the lightbox and change the image etc.
(function() {
var instance = null,
container;
// Constructor
this.MarvLightbox = function() {
instance = this;
// Create global variables
this.images_count = -1;
this.active = false;
this.error = false;
this.debug = false;
// Define option defaults
var defaults = {
activeClass: 'marvLightbox',
appendTo: '#wrapper',
imagesContainer: null,
thumbClass: null,
lightboxId: 'marvLightbox',
galleryFolder: null,
mobileFolder: null,
showAlt: true,
showMax: true,
limit: null,
html: '{ "div": { "id": "{lightboxId}", "0": { "div": { "class": "{lightboxId}__container", "data-click": "EventClose", "0": { "div": { "class": "{lightboxId}__controls {lightboxId}__controls--top", "0": { "div": { "class": "{lightboxId}__eschint", "content": "Press <span>ESC</span> to close" } }, "1": { "div": { "class": "{lightboxId}__close", "data-click": "EventClose" } } } }, "1": { "div": { "class": "{lightboxId}__image", "0": { "img": { "src": "", "class": "responsive-img image", "data-click": "EventRight" } } } }, "2": { "div": { "class": "{lightboxId}__controls {lightboxId}__controls--bottom", "3": { "div": { "class": "{lightboxId}__left", "data-click": "EventLeft", "data-hover": "EventClass(#{lightboxId}, toggle: left)" } }, "4": { "div": { "class": "{lightboxId}__right", "data-click": "EventRight", "data-hover": "EventClass(#{lightboxId}, toggle: right)" } }, "5": { "div": { "class": "{lightboxId}__alt" } }, "6": { "div": { "class": "{lightboxId}__num" } } } } } } } }'

As I said above though the state object appears to be shared between both instances, it should be unique.

The problem lies at instance i think:
var instance = null;
MarvLightbox = function() {
instance = this;
So whenever a new Lightbox is created, instance points to it. This also applies to asynchronous callback functions which will all point to the last instead of the current instance. You may scope instance locally:
var instance=this;
Same applies to state:
MarvLightbox.prototype.current = function() {
console.log(this.state); //make it an objects property, not global
};

.JS not working on Chrome Extension

I'm working on my first Chrome extension to help me on my job.
Well, I have a HTML file as the extension pop-up and a .JS file to do all the magic. When I run the HTML in the browser, it works fine (it has to autocomplete the keywords are being typed) but when I run it as a Chrome extension it does not work at all.
Any idea?

Not working (as a Chrome Extension)

Change select list to ul list.

I have a filterscript that is displayed as select dropdown. I would transform this to regular clickable text in a ul list. Is it possible to replace the select selector in the script somehow and keep the script intact?
<select id="ram" name="ram" class="select single" onchange="location.href=this.options[this.selectedIndex].value">
<option value="" selected="selected">Select / Reset</option>
<option value="2GB">2 GB</option>
<option value="4GB">4 GB</option>
<option value="8GB">8 GB</option>
</select>

The script doesn't support chrome. Read through it in most of the functions like checkForUrlChange() it looks at the name of the browser to decide what to do.
Because chrome and safari are both based on webkit, you can try to change the line useragent.indexOf("safari") != -1 to useragent.indexOf("safari") != -1 || useragent.indexOf("chrome") != -1 to see if that works.
If not, try using unfocus history keeper. It supports Chrome.
