I want to open popup when closing the tab or browser first time and get the user review. I used onbeforeunload(), but I need to handle page refresh and tab close deferent different event.
Short answer: You can't.
Longer answer: For rather obvious "security" reasons it is very limited what you can do when a user tries to navigate away from a page / close a tab or in any other way leave the site.
The reason is that browsers want to make absolutely sure that you cannot prevent the user from closing a tab or window that he / she wants to close.
Therefore the onbeforeunload javascript event - and by extension the beforeunload jQuery event - are extremely limited in what they can do. One of the things they definitely cannot do is prevent the page from closing - except using one very standardized and rather boring method the browser (usually) allows.

I am trying to bypass chromes "Continue from where you left off" session cookie issue, where cookies are not destroyed after closing browser window / tab.
To do this I have added an beforeunload listener to the window, that fires a function to remove a cookie:
window.addEventListener('beforeunload', destroySession)
However this also destroys a cookie when I refresh the page or click on "go back" buttons in the browser, so I need sub sequential checks in my destroySession function to see what caused beforeunload to happen.
The short answer is - You can't.
The long answer is - You can setup a convoluted way of "detecting" a refresh vs being opened in a clean tab or window BUT (there is always a but) note that is is not perfect and each method comes with it's own set of issues (I HIGHLY DO NOT recommend using them): Check if page gets reloaded or refreshed in Javascript
I created a simple JavaScript function to display my pop-up window once it loads. But it keeps on being blocked by Firefox and Google Chrome and I have to somehow enable it on the Firefox and Chrome to display the pop-up.
Are there any alternatives for this?
I have a player on the pop-up window so I have to use a pop-up to let the player play automatically. The problem is that if I put it on the page itself, once the user clicks another page the entire page reloads and the player automatically stops for a few seconds until the whole page reloads and I have to prevent this from happening.
The general rule is that popup blockers will engage if window.open or similar is invoked from javascript that is not invoked by direct user action. That is, you can call window.open in response to a button click without getting hit by the popup blocker, but if you put the same code in a timer event it will be blocked. Depth of call chain is also a factor - some older browsers only look at the immediate caller, newer browsers can backtrack a little to see if the caller's caller was a mouse click etc. Keep it as shallow as you can to avoid the popup blockers.
Please take a look at dthorpe's answer here. It covers your question.
You could try putting the player on the original page, and using something like History.js to control page changes (you could have the main page body in one wrapper div that changes, and leave the player outside of it).
Otherwise, you could try (assuming you meant a HTML5 <video> or <audio> player) downloading the data to localStorage/cookie/[other persistent storage mechanism] and have it seek everytime you change a page.
It will be hard to stop browsers from blocking your pop up window, because any way to do so is inherently exploitable; however, if you call the function to open another window from an onclick event, you may be able to circumvent some popup blockers. Also, some popup blockers allow popups when using the https protocol, although not many have this feature, and https can be hard to implement for the average website, if you don't have physical access to the server.
One other option is to open the other page in another tab (like this w3c example; you can 'click' the link with javascript).
You might also want to look at this post, as it is somewhat similar.
I only just discovered you asked this question.
Here's the answer in full.
Basically, you can simply create the popup immediately as the user event is fired, then fill it with content (your player, for instance) as you have it available.
Hi I have set up a task in my task scheduler to login to my UTM by opening a firefox window at regular intervals. When the relevant URL is loaded a auto-login GM script works on it and logs me in to UTM.
I would like to close that tab after the login is done. If I use
window.close();
It works fine but if no other tab is opened at the time, it simply closes the window.
Without going into details of UTM I would like the following -
A GM hack which closes the tab only if other tabs are already open. If it is the last tab of the window, then it should just replace it with a blank tab (so that window is not closed).
Probably GM cannot obtain any info about the other tabs, but is there any hack ?
As far as I'm aware this isn't possible, if nothing else then for security reasons: you don't spam javascript from your video streaming tab collecting all your data and submitting forms on your behalf.
Here's a thread with a solution that worked for IE7 that you may be able to manipulate but as I said it's not likely.
If you decide to have ago, don't think about identifying the number of tabs, it won't happen, instead focus on determining whether or not there are multiple tabs.
The linked example uses if(clientY == 0) to determine whether or not the browser is closing. This would be a good starting point.
Again, for security reasons, you won't be able to find out information about open tabs.
We'd like to have a message popup when a visitor to specific webpages leave those webpages. So we could tie some Javascript to the links on those webpages, but then we can't control if the user exited the webpage by typing in a URL, using a bookmark or just closing the window...
I assume we have limited options if the user tries closing the browser window... but I do know it's possible because Google Docs' Documents offers the chance to cancel closing the window if you have unsaved work while closing the browser.
What are my options? Can I have Javascript called upon going to another webpage? Can I control the text in the popup when trying to close the window?
I'm using jQuery, so if there are good solutions implemented with jQuery that's perfectly fine.
Yes.

jQuery UI Dialog OnBeforeUnload
There is onunload event you can bind to, first example:

Google toolbar is creating a serious problem for me in IE 6 when i try to open a window using window.open or if i set target="_blank" for anchor tag. It treats the window as pop up and dispaly pop up is blocked which i really don't want to dsiplay to my user. This problem only occurs if there is a extra code getting executed before window.open, e.g. calling another method at onclick then using window.open. Can somebody tell me how to solve this issue?
The toolbar and other devices like that are intended to protect users from unwanted popup windows. The only way for them to determine whether a window is "wanted" is to determine whether window.open is being called in an event handler for a user-initiated event, like a button click. Thus if you try to do something like call window.open on document load, or in an AJAX success handler, the toolbar (and other blockers) will assume that the popup is suspect.
There's nothing you can do about this other than, as noted by Mr. Buchan, tell your users what to expect. Wherever possible, have your popups launched directly from click handlers.
A more radical change would be to shift away from window.open and use simulated popup windows made from floating elements that cover up part of the page. Something, that is, like what jQuery UI dialogs give you.
Adding the site to your Trusted Sites will work.
Setting target="_blank" shouldn't be triggering a pop-up blocker.
