Using JavaScript, is it possible to add a bookmark in Firefox directly, without opening any dialog box? That is, I want the user clic on a link and that the bookmark is automatically created, without the need to any further step.
Fortunately, no. It would be a horrible breach of security.
Could be a different story in the context of a Firefox Extension, but I assume you are asking for a normal web page.
If it was possible, any possible website would be able to create any kind bookmark, without the user even noticing.
As a user, I certainly hope this is not possible ^^
(And, as a developper, I don't think it is)

I have a web extension that lets any website access the clipboard. On request I will ask the user if it is okay to give access to the clipboard.
I do this in two ways
I create a notification
The problem: firefox doesn't allow buttons, so in the message I say "Click here to allow website x access". I added an eventlistener to the notification that sends a message back to the content script and it proceeds from there. It's okay but not really the best solution (I want buttons)
As a fallback I have a simple confirm box.
The problem: it doesn't really look good.
Now my other idea is to create a custom confirm box. That means create some html, css and javascript and append it to the DOM. This although is potentionally dangerous as websites can just trigger a "click" on the "allow access"-button then.
So I am basically looking for a nice and safe way to get confirmation from the user.
So what next? iframes? Is it possible to include an html page from the addon with access to a content script in an iframe?
Or is there some other way I can implement this maybe web extensions already offer something like this?
Completely overlooked the click event argument. There is a event.isTrusted property which is false when the event was triggered. (maybe not available in all browsers). But this pretty much solves the issue.
I use a lot of JavaScript on my site (currently under construction). My worry is if some of the client side's system has JavaScript disabled then my site will "miserably fail".
I know that we cannot programatically override to enable JavaScript as it would be a security issue. But what I want is if the client side system has JavaScript disabled then a popup should appear with a button so that when the user clicks the button automatically JS will be enabled no matter in what browser he is viewing the site.
I am asking this because I saw the same thing myself when I viewed some other site.
That is not possible. You can however display instructions on the page on how to enable JavaScript, but considering that people who disable JavaScript usually know what they are doing they'll know how to enable it themselves.
I'd say there are very few people who accidentally disable JavaScript, so your worries are probably unnecessary.
Well if you want a popup to appear then you need to make it happen using javascript, so I guess the answer is that you can just ignore the very small percentage of people who have javascript disabled for their browsers.
What you are probably looking for is Progressive enhancement.
Instead of showing a message through JavaScript that tells the user to enable JavaScript you do it the other way around.
By default you show a message, in a div for example, and when JavaScript is enabled you hide the div. You only use JavaScript to enhance the user experience but offer a 'reasonable' experience when the user doesn't have JavaScript enabled. Reasonable could mean in your case an empty page with some text that explains why you really need JavaScript.
I would like to identify browser tabs (on my domain) using JavaScript.
I mean that if user open several tabs with my website and submit web form only on one page I want to notify only this page, even if user moves from this page.
It should be max cross browsers solution.
P.S. One of the possible solutions is using "window.name" property, but I do not want to use it because somebody else can use it.
P.S-2: I found one more possible solution: using sessionStorage. It supported by FF3.5+, Chrome4+, Safari4+, Opera10.5+, and IE8+. Oooohhh, I need IE7!!!!
Thank you in advance!
I don't think this can be done. Each browser tab that is opened is basically like a new browser instance. Just like if the user opened another browser. One tab knows nothing about the other tab by design. This is how it should be. Can you imagine the implications if a web site developer could add code to their page to "see" what other sites you have opened in your browser?
window.name is the only persistent data element you can use for this purpose, as described your requirements.
I want to notify only this page, even if user moves from this page.
This is impossible. Once a user navigates away from a page, you lose control over that tab. You can't push to a page, it needs to make a server request FROM that page, even if it's ajax.
Using sessionStorage. It supported by FF3.5+, Chrome4+, Safari4+, Opera10.5+, and IE8+.
For IE7 using "window.name" property.
I have a requirement where I need to print a specific word document when I click on a button in IE8/IE9. I tried to find a way using ExecWB and other methods but could not achieve my goal. Couple of constraints I have are as follows.
The word document is availble through URL and this URL is from a different site than the page where I am clicking the button to print (XSS considerations ?)
I need to directly print using default printer without popping up the print dialog.
Is this possible in anyway?
Impossible from within the context of HTML page, without a custom browser extension. Word document must open before it's printed (maybe not visually presented to the user upon opening, but MS Word or some other application that is capable of opening word docs must be installed on the client system. There is Office extension for IE, which can be used to open the document, but the user has to click on the print button to invoke the dialog. There's nothing that you can do from within javascript to accomplish that. I'm sure you could, if you wrote your own IE extension/plugin, but unless your users are corporate that must install it, nobody else will.
I hope I'm not lying to you.
I want to have a link or something which could be inserted in an email/forum etc. It's a typical url. But I would like that link to be opened in a custom sized new browser window ( say 800 x 600 ) . It sounds weird, but that is the requirement. Can it be achieved somehow?
Thanks
In an email?
You can't. Email clients insane enough to execute JavaScript are all by unheard of.
In a forum?
Assuming you aren't the administrator of it, you can't. Forums insane enough to encourage XSS attacks are, again, all but unheard of.
Ok. This is how we could kinda achieve this. Let that link be a normal link. It would contain the custom code to create a desired popup on invocation. But the issue is popup blocker in browser. But they somehow liked it.So basically a page opens up which launches the popup without user interference.
