I've been doing some research on this and I'm still not sure if it's possible.
Is there any way to retrieve a user's bookmarks and display them on the page without violating their privacy? I saw these two threads talking about using JS to do this:
How to get Bookmarks toolbar information in JavaScript code?
Show all bookmarks using javascript
I'm not thinking about doing this automatically, users would have to opt-in with a button that said "Display Bookmarks from My Browser" or something similar.
Is it possible?
Not without browser extensions. You could write a browser extension for the major browsers which retrieves the information and feeds it back to your page.

I'm writing an app which involves letting users to share comments on a website, which has a comment form with Google's reCAPTCHA embeded. I would like to load this page via HTTP and display CAPTCHA within my app, so that user can post comments from my app. Is it easy to implement or should I rather try other solution?
EDIT:
I've red reCAPTCHA developer guide. If I would like to embed captcha inside my form, I'd need to insert div element with a proper class, and make a ajax request in order to render captcha. This call would insert an iframe into a given div. What I need is to know how to access that iframe's content without using AJAX.
Turns out we are not supposed to do that kind of tricks with reCAPTCHA.
There is no support for that in API. It seems that it was part of Google's design to prevent that kind of usage.
The only walkaround I could come up with is to implement a WebView widget with JavaScript support, get website via http, and load it into this webview, centering this view around the form we want to post.
It seems like a lot of work though, thus I'm going to simply skip this, if someone successfuly manages to figure it out I'd appreciate a hint :)
This works in other browsers but not in chrome. I am trying to allow users to upload large files and have an ajax call to update them on the progress of the file upload.
So a unique ID is generated on the client side and added to the action of the form before sending. Then the form is submitted (form only contains a file upload input) and an ajax call is made to get the progress of the upload.
The ajax call goes to another page and uses the ID to lookup the upload.
I am using JQuery 1.5.1. Debugging this and putting something on the error function give me nothing other than "error". Not very helpful. I used Chrome's debugger and it just says failed to load resource xxxx.aspx. xxx.aspx is the URL i needed. Turns out that there seems to be some sort of conflict between the form and the ajax call.
Is there some way to get around this?
you should really look at SWFupload, a great flash based uploader, with concurrent upload and progressbar support. Also it makes it really easy to use server-side, you dont need to implement upload percentage view as it client-side based.
not exactly an answer to your question, but a link to a tool that can really help you drill down and find good error messages, step through javascript code and such would be firebug for Chrome, I got the IE and Chrome versions working and use it very regularly, it has been a life saver and greatly has decreased debugging time:

I would suggest making firebug a common tool in your debugging arsenal.
Use SlickUpload
It is a server control and module that does exactly what you are looking for and takes less than 10 minutes to setup.

Is there any option for getting Bookmarks toolabr information from javascript code, i.e.
Can we get information what are bookmarkleted in the Bookmarks toolbar [url, text etc.]?
It depends on the toolbar you are talking about (a browser bookmarks bar? which browser?) and the environment the JavaScript executes in.
Assuming the latter is "a webpage loaded in a browser", then the answer is 'no, that would be a horrific invasion of privacy and security risk'.
Other environments (e.g. a browser plugin) have different restrictions and may allow access.
I think you can't. This would be privacy violation.
Ex: your js read bookmarks information and send by ajax to your server.
I am working on a Flex AS3 application and wanted to add the Facebook Like button inside the app. I am unable to find any API or anything apart from the http://developers.facebook.com/docs/reference/plugins/like code generator.
Any ideas on how this might be accomplished? I am quite new to the recent changes in the Facebook Platform, so any info would be appreciated.
A direct "like" button should not be possible, since Facebook needs to sandbox the whole thing. Both like button formats (iframe and xfbml) use a sandboxed iframe, so nobody but facebook can set "likes" or know anything about the user.
For that to work with Flash, I think facebook would have to provide the button itself as a SWF file so you can load it in Flash. Then it can create a sandbox within itself and thus load the user information safely. Very much like the Chromeless Youtube Player, where it's almost impossible for Flash to access the actual FLV URL (even through introspection).
But even so, I don't think this would provide enough security... realize that you are dealing with very private user information and credentials here.
The only way I know you can "like" stuff through Flash is first doing the whole Facebook Connect thing (several popup windows asking the user for permissions) and then using the API of your choice to do the actual "liking", for instance, with the Graph API:
http://developers.facebook.com/docs/api#publishing
The closest information I could find are these 2 items so far. Hope it helps you in your journey.

Facebook like button in flash
I hate answering "no" to a question because what I really mean is "I don't know and I can't find a way". I'm sure your Google-fu is as good as mine. All I can see are Facebook forum posts like this where people are asking the same question and no one is answering.
The examples they give of the like button are either embedded in iFrames or using XFBML <fb:like ../> tag. There are no examples of how to like something using their new graph api or either of their old APIs (FQL and REST API).
I had to get a Facebook like button in a html page (looked like a header on the top) and get the swf embedded below. As its a complete flex app in my case, this work around was possible and plausible
I have an ASP.Net application which as desired feature, users would like to be able to take a screenshot. While I know this can be simulated, it would be really great to have a way to take a URL (or the current rendered page), and turn it into an image which can be stored on the server.
Is this crazy? Is there a way to do it? If so, any references?
I can tell you right now that there is no way to do it from inside the browser, nor should there be. Imagine that your page embeds GMail in an iframe. You could then steal a screenshot of the person's GMail inbox!
This could be made safe by having the browser "black out" all iframes and embeds that would violate cross-domain restrictions.
You could certainly write an extension to do this, but be aware of the security considerations outlined above.
Update: You can use a canvas utility function to get a screenshot of a page on the same origin as your code. There's even a lib to allow you to do this: http://experiments.hertzen.com/jsfeedback/
You can find other possible answers here: Using HTML5/Canvas/JavaScript to take screenshots
Browsershots has an XML-RPC interface and available source code (in Python).
I used the free assembly UrlScreenshot.dll which you can download here.
Works nicely!
There is also WebSiteScreenShot but it's not free.
You could try a browser plugin like IE7 Pro for Internet Explorer which allows you to save a screenshot of the current site to a file on disk. I'm sure there is a comparable plugin for FireFox out there as well.
If you want to do something like you described. You need to call an external process that prints the IE output as described here.
Why don't you take another approach?
If you have the need that users can view the same content over again, then it sounds like that is a business requirement for your application, and so you should be building it into your application.
Structure the URL so that when the same user (assuming you have sessions and the application shows different things to different users) visits the same URL, they always see same thing. They can then bookmark the URL locally, or you can even have an application feature that saves it in a user profile.
Part of this would mean making "clean urls", eg, site.com/view/whatever-information-needed-here.
If you are doing time-based data, where it changes as it gets older, there are probably a couple possible approaches.
If your data is not changing on a regular basis, then you could make the "current" page always, eg, site.com/view/2008-10-20 (add hour/minute/second as appropriate).
If it is refreshing, and/or updating more regularly, have the "current" page as site.com/view .. but allow specifying the exact time afterwards. In this case, you'd have to have a "link to this page" type function, which would link to the permanent URL with the full date/time. Look to google maps for inspiration here-- if you scroll across a map, you can always click "link to here" and it will provide a link that includes the GPS coordinates, objects on the map, etc. In that case it's not a very friendly url but it does work quite well. :)
