I like the integration of the Dragonfly IDE in the Opera Browser. Especially, the link between the visual and the code perspective allow easy editing of the corresponding HTML code. However, I have not found a way to save my changes to the local file.
I have a simple static website that is stored on my local harddisk.
I open the file in Opera Developer (Version 28.0)
I use the 'inspect element ctrl+shift+i' menu option to open dragonfly
I make the changes and check them in the browser
I save the html file from dragonfly
Observation: changes are not saved.
Is there way to save the interactive changes permanently?
It's not really possible, It's just a developer tool.
You can change it on Dragonfly but it won't modify the file.
2 solutions :
you change manually the HTML file with an editor like Notepad after each change on dragonfly
You use some software like Dreamweaver that allow you to see what you're editing in real time and save these changes.

How can I make dynamically changed user script using Tampermonkey in Safari without actually open Tampermonkey and edit some code manually? I want to change the contents of a script on the fly. I used to do this in Chrome with #require attribute pointing to a javascript file in my file system. Then I programatically changed that javascript file accordingly. Worked like a charm. This doesn't work with Safari, due to it's security.
I tried manually changing the /Users/mainuser/Library/Preferences/com.apple.Safari.Extensions.plist file, but that results in corruption of Tampermonkey, since Safari doesn't like to see users changing it's preferences manually. It does some checks to see if someone tempered with it. Don't know which file should also be edited to avoid this. So the question remains, how can I dynamically change content of user script in Safari?
Is it possible to spoof Chrome plugins?
I noticed that their names are stored in Preferences and Local State file in /Users/mainuser/Library/Application\ Support/Google/Chrome/Default/Preferences and /Users/mainuser/Library/Application\ Support/Google/Chrome/Local\ State respectively (on Mac), but manually changing the contents of these files gets treated as file corruption. Any idea how to spoof it?
Plugin information are publicly available and are easily inspected with something like this:
var x=navigator.plugins.length; // store the total no of plugin stored
console.log(x);
var txt="";
for(var i=0;i<x;i++)
{
txt=navigator.plugins[i].name;
console.log(txt);
}
I assume you want to modify an extension that you have installed on your machine in order to improve it.
You can use the Developer Mode and load the modified extension:
Extensions that you download from the Chrome Web Store are packaged up
as .crx files, which is great for distribution, but not so great for
development. Recognizing this, Chrome gives you a quick way of loading
up your working directory for testing. Let's do that now.
Visit chrome://extensions in your browser (or open up the Chrome menu
by clicking the icon to the far right of the Omnibox: The menu's icon
is three horizontal bars. and select Extensions under the Tools menu
to get to the same place).
Ensure that the Developer mode checkbox in the top right-hand corner
is checked.
Click Load unpacked extension… to pop up a file-selection dialog.
Navigate to the directory in which your extension files live, and
select it.
Alternatively, you can drag and drop the directory where your
extension files live onto chrome://extensions in your browser to load
it.
If the extension is valid, it'll be loaded up and active right away!
If it's invalid, an error message will be displayed at the top of the
page. Correct the error, and try again.
Paranoid about browser fingerprinting I guess.
If you want hide navigator.plugins list, see this plugin :
https://github.com/bcaller/plugin-privacy-chrome
See content.js#L27 :
properties.plugins = vecw({}, true);
The "real" fix is to stop the enumeration of plugins for everybody, so there is no fingerprint information (after everyone upgrades):
https://bugs.chromium.org/p/chromium/issues/detail?id=271772
If you hide navigator.plugins, that is also an identifying (single bit) feature that will make you stand out since there will be very few users who hide navigator.plugins. Which is why you'd want to spoof.
From another answer, from #Hors Sujet, https://github.com/bcaller/plugin-privacy-chrome is a great place to start how to program a spoof. You'll want to look like the vast majority of Chrome users (I'm not sure that actually exists, though.)
But what you likely really want is EFF's Privacy Badger.
Start here to see the number of bits you can be fingerprinted by:
https://panopticlick.eff.org/
And then install Privacy Badger from here:
https://chrome.google.com/webstore/detail/privacy-badger/pkehgijcmpdhfbdbbnkijodmdjhbjlgp
asking again the question Using Google Chrome to debug and edit javascript embedded in HTML page
if there is a Javascript embedded in html page can i edit it .in this question he accepted an answer.In this answer's second comment by antyrat "Well you're right, but you can edit this at Elements tab instead." but when i edit javascript in script tag changes doesn't affect code flow.Please guideline is it possible to change embedded js in html page in chrome dev tools or not ??
You can make changes to the javascript in a page using chrome developer tools but those changes do not get saved. You will need to manually go and change it in the respective .js file for the changes to take effect. Only if you want to preview the change temporarily, you can try those with the chrome developer tools
I'm working on a file upload utility based on Valum's Ajax-Uploader. The idea is similar to the Gmail attachment process. The user should be able to drag a file from the desktop into the browser window and onto the file upload area to get it to upload. This works fine in the browsers that support this functionality (Firefox 3.6+, Chrome 7+).
The problem I'm running into are the styles that should be re-drawn when the user:
Drags the file anywhere in the browser
Drags the file into the upload area
I have tested in the exact same browser versions on WinXP, Vista, and Win7. The appropriate styles are redrawn. However, in Windows Server 2003, they do not.
In Win2003, when I inspect the div that should be redrawn via Firebug, the "drop-area" and "drop-area-active" classes are applied correctly. Firebug even shows the correct style declarations, but the changes are never visible.
The only difference between FF and Chrome that I'm able to spot is that in Chrome, the "drop-area-active" style is displayed for a split second when the user drops the file.
I'm not positive that it is a Windows2003 issue, but that's the only OS in which I'm able to recreate the bug.
Edit:
If you're running Win2k3, try the Gmail drag'n'drop functionality. I can see the alternate styles in other OS's, but not Win2k3.
Edit #2:
Still seeing this issue in many different places. Anyone have any suggestions? I have submitted this as a bug to the Chromium Project. Issue 68632.

How to get effective HTML after executing all scripts?
Actually scripts are adding and modifying control and css in the page. I would like to see html of resultant display as a static page. Is there any way to get this?
Edit: Suppose if background image is added using javascript, How can i see in Html OR css?
Please try to get this before giving answer.
One way would be to use Firefox with the Firebug extension.
Firebug is an extension for web developers. Among other things, it offers an "HTML panel":
The HTML panel displays the generated
HTML/XML of the currently opened page.
It differs from the normal source code
view, because it also displays all
manipulations on the DOM tree.
[...]
A similar solution for MS Internet Explorer would be the Internet Explorer Developer Toolbar.
Note that both solution are browser-specific. There is no way to get the resultant HTML independent of the browser used, because this HTML only exists in the working memory of the browser (so you cannot, say, sniff it on the network).
Use the firebug plugin for firefox, with it you can 'view generated source'.
This is a javascript approach. Unfortunately, it doesn't work perfect. For example, it doesn't include the contents of textarea's.
document.documentElement.innerHTML
Another way is selecting everyting (Ctrl + A) and choose 'View selection source' from a context menu.
The Web Developer Toolbar addon for Firefox has a 'View Generated Source' button that let's you do that. It's under the 'View Source' Menu of the toolbar.
It presents manipulated document as a static source, like what the "View Source" option does, but with modification by the Javascript.
