  • document.getElementById() returns null when using mozrepl (but not in firebug)

    - by teamonkey
    I'm trying to use the mozrepl Firefox extension to give me a Javascript REPL from within emacs. I think I've got it set up correctly. I can interact with the REPL from emacs and can explore the document pretty much as described in the tutorial pages. The problem comes when I try to do something really simple, like get a context to a canvas element: repl> document.getElementById("mycanvas").getContext("2d") !!! TypeError: document.getElementById("mycanvas") is null Details: message: document.getElementById("mycanvas") is null fileName: chrome://mozrepl/content/repl.js -> file:///C:/Users/teamonkey/AppData/Roaming/Mozilla/Firefox/Profiles/chfdenuz.default/mozrepl.tmp.js lineNumber: 1 stack: @chrome://mozrepl/content/repl.js -> file:///C:/Users/teamonkey/AppData/Roaming/Mozilla/Firefox/Profiles/chfdenuz.default/mozrepl.tmp.js:1 name: TypeError It's not just that particular instance: any call to getElementById will just return null. If I start up firebug I can enter the same thing and it will return a valid context, but I'd really like to get the REPL working in emacs. I don't think this is a bug but I've probably not configured mozrepl correctly. Can anyone help? Mozrepl 1.0, Firefox 3.6

  • How does browser know when to prompt user to save password?

    - by Eric
    This is related to the question I asked here: http://stackoverflow.com/questions/2382329/how-can-i-get-browser-to-prompt-to-save-password This is the problem: I CAN'T get my browser to prompt me to save the password for the site I'm developing. (I'm talking about the bar that appears sometimes when you submit a form on Firefox, that says "Remember the password for yoursite.com? Yes / Not now / Never") This is super frustrating because this feature of Firefox (and most other modern browsers, which I hope work in a similar fashion) seems to be a mystery. It's like a magic trick the browser does, where it looks at your code, or what you submit, or something, and if it "looks" like a login form with a username (or email address) field and a password field, it offers to save. Except in this case, where it's not offering my users that option after they use my login form, and it's making me nuts. :-) (I checked my Firefox settings-- I have NOT told the browser "never" for this site. It should be prompting.) My question: exactly what the heuristics are that Firefox (or any other modern browser) uses to know when it should prompt the user to save? This shouldn't be too difficult to answer, since it's right there in the Mozilla source (I don't know where to look or else I'd try to dig it out myself). You'd think there would be a blog post or some other similar developer note from the Mozilla developers about this but I can't find that either. (* Note that if your answer to me has anything to do with cookies, encryption or anything else that is about how I'm storing the user's passwords in the database, you've probably misread my question. :-)

  • CloseHandler<Window> and Window.ClosingHandler() working differently in IE

    - by stuff22
    It seems that CloseHandler and Window.ClosingHandler() are not working or are not triggering the events in the same way under IE as opposed to Firefox. Window.addWindowClosingHandler(new Window.ClosingHandler() { @Override public void onWindowClosing(ClosingEvent event) { event.setMessage(message); } Window.addCloseHandler(new CloseHandler<Window>() { @Override public void onClose(CloseEvent<Window> event) { //Window.alert("debug1"); if(recordId!=null){ DatabaseQueryServiceAsync dbQueryService = DatabaseQueryService.Util.getInstance(); dbQueryService.releaseRecordLock(recordId, new AsyncCallback<String>() { @Override public void onFailure(Throwable arg0) { } @Override public void onSuccess(String arg0) { } }); } } }); }); For example, the ClosingHandler under IE displays the message when I swap a panel within within my widget. This does not occur in Firefox. The CloseHandler doesn't seem to trigger at all when the window closes in IE, but does so in firefox. The interesting thing to point out there, is that when I put a Window.alert("debug1") message in the addCloseHandler() method it DOES run the callback below, but as soon as I remove it, the callback doesn't happen. In firefox it works and runs the callback in both situations. So, I'm basically pulling my hair out not really understanding what's going on. Any help would be greatly appreciated. Thanks.

  • Why would certain browsers request all pages on my ASP.Net Web site twice?

    - by Deane
    Firefox is issuing duplicate requests to my ASP.Net web site. It will request a page, get the response, then immediately issue the same request again (well, almost the same -- see below). This happens on every page of this particular Web site (but not any others). IE does not do this, but Chrome also does this. I have confirmed that there is no Location header in the response, and no Javascript or meta tag in the page which would cause the page to be re-requested (if any of these were true, IE would be re-requesting pages as well). I have confirmed this behavior on multiple Firefox installs on multiple machines. Versions vary, but all are 3.x. The only difference between the two requests is the Accepts header. For the first request, it looks like this: Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 For the second request, it looks like this: Accept: */* The Content-Type response header in all cases is: Content-Type: text/html; charset=utf-8 Something else odd -- even though Firefox requests the page twice, it uses the first response and discards the second. I put a counter on a page that increments with every request. I can watch the responses come back (via the Charles proxy). Firefox will get a "1" the first time, and a "2" the second time. Yet it will display the "1," for some reason. Chrome exhibits this exact same behavior. I suspect it's a protocol-level issue, given the difference in Accepts header, but I've never seen this before.

  • Automatically clear cache of all major browsers installed

    - by MorganTiley
    I would like a way to clear cache from all my locally installed browsers - quickly and easily. A simple utility that would ask "Clear all browser caches?" with Yes/No. Just the major browsers -IE, Firefox, Safari, Chrome and optionally Opera I understand CCleaner can do this but it is not as simple as I would like (as it has other functions as well). I tried googling/stacking and couldn't find anything.

    So far all sites have played nice but recently i ran into a site which aggressively tries to get users to sign up and pretty much puts the site on lockdown after 10 pageviews without signing up. What firefox extension can i use to either freeze or disable cookies for this one specific site? I dont want to whitelist every site i visit because one site is giving me trouble.

  • How to tunnel all traffic through Tor?

    - by HappyDeveloper
    All I want is be able to use flash and javascript while using Tor (I don't intend to use it for torrents) Normally, using flash with Tor is not recommended because firefox plugins run outside of the sandbox, so the browser's proxy settings don't apply to them, and can reveal your real IP. But I think it should be possible to also redirect flash to the same socket as the browser, and block the other outgoing ports just in case. Any ideas on how to do this?

  • Looking for a AutoZoom browser plugin

    - by AngryHacker
    I have a pretty large 24" wide screen with a pretty high resolution. When I browse, some sites have a fixed layout and there is basically a narrow column. So I typically zoom in to the point just before the level where I have to scroll horizontally. Is there a browser plugin that auto-zooms in (or via a button or gesture or whatever) to the max available real estate? I'd prefer a plugin for Chrome, but Firefox will do too.

  • Reduce Mac OS X's Flash CPU usage

    - by elhombre
    I have been experiencing high CPU usage (138%) on my MacBook, while looking at flash videos on the internet with the Firefox browser. Mostly this usage makes itself noticeable by the loud noise of the fans and a hot MacBook which is very annoying for me. Does anyone know how to solve this problem or a workaround in of any kind?

  • Ubuntu cannot play all the videos on yahoo

    - by Draco Ater
    Hello, I have latest Ubuntu installed, with firefox 3.6.3. I have flashplugin-installer and ubuntu-restricted-extras installed. No other package concerning flash (gnash, swf) is installed. I can play videos on youtube or some other sites, some even some videos on yahoo, but I cannot play this video (and some others) - the blue circle in the center (like loading...) keeps flashing forever. Why can't I play it, and how to make it play?

  • WebGL Not working in FF4b7 (with enabled_for_all_sites=true)

    - by tj111
    I was trying to load the cool Kataspace WebGL demo (more info) and I get the error message "Your browser doesn't support WebGL. Currently we recommend the latest Firefox 4 Beta for all platforms." I checked around and every piece of advice I can find on the internet says to set webgl.enabled_for_all_sites to true in the about:config page. Mine is set to true yet I still receive the same message. Does anyone know of any other items that may be conflicting with WebGL running properly?

  • Browser resizing when the monitor turns on/off?

    - by Jason
    The last week or so I have noticed an odd thing. When I turn on my monitor, my browser windows are all half the size they were when I turned it off. Sometimes when I turn it on the taskbar is even half way up the screen for a few moments, as if turning the monitor on and off was forcing it to change the resolution. I use firefox, running windows 7.

  • How do I securely delete cookies and saved passwords?

    - by Matt Solnit
    Is there a way, from inside the browser, to delete cookies and saved passwords in such a way that the data is unrecoverable (similar to Secure Empty Trash)? I know I can probably track down all the files involved and then manually do this, but I'm curious if there's an easier way. Or maybe browsers already do it out of the box? I'm specifically looking for solutions for Firefox and Safari, on Mac OS X.

  • Saving blog items as pdf's

    - by ldigas
    I know of FireShot, a firefox extension, for saving up whole pages of images. And I love it. Great idea, and a very good implementation. But unfortunatelly, often on this kind of sites, you have links which get lost that way. So I'm wondering, is there a way to save in the same manner whole blog posts, wiki posts, StackOverflow posts :), as PDF files, so the links get saved as well ?

  • Tool to highlight and annotate text on websites?

    - by doug
    When I read something I need to underscore what I like, or what I think is important, and to take notices about that read, near on that current paragraph. So, does anyone know a Firefox add-on or something else (another browser, any other application) which can provide me such a functionality? ps: I've tried some research tools as Zotero, but it is not what I'm looking for.

  • How print multiple independent pages in one print job?

    - by C.W.Holeman II
    How can I combine multiple single page prints into a single print job? For example, using Firefox on Linux one can print a web page such that each sheet of paper has four pages printed upon it. I would like to combine several separate web pages so that for example, web-page-a, web-page-b and web-page-c (each less than one print page long) are printed on a single sheet of paper. I would like to do this without having to use some for of image editor to combine them.
