I'm looking into chrome frame and I'm wondering how it works.... http://scriptsrc.net shows that it's a javascript that can be embedded on the page....
http://code.google.com/chrome/chromeframe/ shows it as an install file... does the JS prompt for an installation or something?
Google chrome frame is a plugin (think Adobe Flash) for Internet Explorer, that replaces core modules of IE (unlike Flash), like layout/rendering and javascript. But the UI remains. Then there is some javascript that can detect if this is real IE or IE+Chrome, and also offer an install option to the user. Also there is a HTTP-header and a meta-tag that are required to switch IE to chrome mode, when available.
The JavaScript is to detect it and enable it if it's there. (scriptsrc is just giving you the link to the file, which is on the Google CDN.) The end user does have to do a one-time install of it, it's a plug-in (like Flash or Java). Quoting from this page in the Google documentation:
In Internet Explorer, check() determines if Chrome Frame is installed. If not, the user is prompted to install it.

I am using Firefox 50.0. After auto update of Firefox to version 50.0, Firebug has stopped working and attempting to use it is showing an inbuilt Firefox console while inspecting any DOM element.
Is there any patch to use Firebug on Firefox 50.0 version?
Solve The problem by Changing Mozilla Browser Configuration Settings.
Open A Blank Tab
type about:config in address bar then press enter (click on I accept the risk!)
find browser.tabs.remote.autostart
select the option then click the mouse right side
Turn The Option As False
Close the browser for restart browser
open browser again, inspect the element. I hope It Works Properly.
I manage to get Firebug work again, so here is what I done.
Everyone knows that Firebug isn't being developed or maintained any longer because it can't work with e10s, so here is my workaround:
Download Firefox Developer edition so you can allow XPI installation.
firefox-53.0a2.en-US.win64.installer.exe or
firefox-53.0a2.en-US.win32.installer.exe
Run Firefox developer edition after installing and go to the about:config (type in url bar)
Find xpinstall.signatures.required (set to false)
Find browser.tabs.remote.autostart (set all to false: browser.tabs.remote.autostart.1 and browser.tabs.remote.autostart.2)
NOTE: The Multi-process architecture improves the browser's stability, performance and security by separating tasks into processes, you disabling it at own responsibility.
After that you need to restart the browser.
Now you can go at the Firebug repository and install desired version
Here you can find all Firebug installations
I chose latest firebug-2.0b8.xpi and it forking fine.
P.S. You can disable updates for Firefox Developer edition.
Hope it helps.
Head over to Firebug website, you can see following message:
The Firebug extension isn't being developed or maintained any longer. We invite you to use the Firefox built-in DevTools instead.
Also Sebastianz told me,
Firebug is discontinued. The team has split up, the former team leader Jan "Honza" Odvarko is working on the Firefox DevTools now.
As #Makyen said in his answer, Firebug does not work with multiprocess Firefox, so remove Firebug right now and try Firefox DevTools instead, it's not optional (sadly), unless you don't update Firefox :)
Update 1
Take a look # Why got Firebug removed after updating Firefox to version 50?
Update 2
Take a look # my answer here: how to revert firebug to old version
Firebug does not work with multiprocess Firefox
The Firebug site claims that:
Firebug 2.0.18 is compatible with Firefox 30 – 52
However, it also explains that [emphasis mine]:
Firebug 2.0.18 fixes issue 8030. The extension is marked as multi-process (e10s) compatible so, it isn’t blacklisted and users can continue installing it. This way Firebug can help users to easily migrate into built-in Firefox developer tools – in case it’s running in multi-process enabled browser. When opened in a multi-process Firefox, Firebug’s tools cannot be used. Firebug will then only assist the user with migration to Firefox’s built-in tools.
They also direct you to read: Unifying Firebug & Firefox DevTools
That page says that [emphasis mine]:
Firebug 2 doesn’t work in multi-process browsers (i.e. e10s) and converting it is too complex, so it will stop working when e10s is activated in Firefox. You will be able to disable e10s for a while to keep using Firebug 2, but this won’t last forever.
The fact that Firebug does not actually work in multiprocess Firefox will account for different people having different experiences with Firebug working or not working in a particular version of Firefox. Firefox automatically enabling multiprocess mode will depend on multiple factors, including what other add-ons are installed in the profile.
Using Firebug in newer versions of Firefox
Thus, to use Firebug in newer versions of Firefox, you will need to disable Firefox from entering multiprocess mode. This can be done from the about:preferences page (also available from Tools➞Options). This an option which is under the "General" tab as "Enable multi-process Firefox ...". If multiprocess is not available, this option will not be shown. This option can also be changed by adjusting the preference browser.tabs.remote.autostart from about:config. [Note: browser.tabs.remote.autostart.2 and browser.tabs.remote.autostart.1 also appear to be used to indicate default states, thus I suggest using the about:preferences page to change this option.]
You can determine if your Firefox is currently running in multiprocess mode by looking in about:support. The line "Multiprocess Windows" under "Application Basics" will state if multiprocess is enabled or disabled.
Set up profiles explicitly for testing
Personally, I have different profiles set up for each of multiprocess explicitly disabled and multiprocess explicitly enabled (set browser.tabs.remote.force-enable to true), so I can perform testing under both conditions, with the state of multiprocess being enabled/disabled being known in advance.
I had the same problem when I updated Firefox. I was so addicted to firebug but I moved on to Firefox developer edition - https://www.mozilla.org/en-US/firefox/developer/
It also comes with the firebug theme which resembles firebug UI and its efficient.Just install FDE and activate the firebug theme as shown in the image below :
I had the same unexpected surprise when ubuntu updated FFX and suddenly things like the script panel stopped working. Since I was in the middle of working on something with a short deadline, I was not going to have the luxury of learning the firefox developer toolset and desperately needed to get firebug working. The fix that finally worked for me was to set Firefox preferences not to update. Then download v 49.0.2
https://support.mozilla.org/en-US/kb/install-older-version-of-firefox
I also had to tell Ubuntu not to include firefox in it's upgrades.
It looks like firebug will no longer be maintained as a seperate project, so you will want to get familiar w/ the built in dev tools, but hopefully this buys you some time. Worth mentioning (if I'm reading this right, it sounds like it will be integrated into the native tools:
https://blog.getfirebug.com/2016/06/07/unifying-firebug-firefox-devtools/
https://github.com/firebug/firebug.next
Its working. You need to install one more add-on "Firepicker" and restart the Firefox.

I managed to resolve this issue by simply downgrading to mozilla old version using this url:
open https://ftp.mozilla.org/pub/firefox/releases/50.0/win64/en-US/
download and run the .exe setup
Go to Settings - > Add Ons
Click on extensions and search for firebug and firepath and then add those extensions
Hope this should resolve the issue. For those using Windows 32 machine can use the url
https://ftp.mozilla.org/pub/firefox/releases/50.0/win32/en-US/
http://toolsqa.com/selenium-webdriver/xpath-helper/
Open a new tab and navigate to any webpage. I have used www.DemoQA.com for demo.
Hit Ctrl-Shift-X (or Command-Shift-X on OS X), or click the XPath Helper button in the toolbar, to open the XPath Helper console.
Hold down Shift as you mouse over elements on the page. The query box will continuously update to show the XPath query for the element below the mouse pointer, and the results box will show the results for the current query.
If desired, edit the XPath query directly in the console. The results box will immediately reflect your changes.
Repeat step (2) to close the console.
Using firefox, the toolbar appears as expected, not on chrome or internet explorer.
How do I fix this? Thanks
Clear your browser cache.
Check the console for any errors.
Check your website for conflicting CSS styles.
If you are using any third-party plugins, try one of the official presets (Basic, Standard, Full) and make sure you're using the latest version.

I'm trying to access articles through Wiley publishers website (onlinelibrary.wiley.com) and the PDF viewing function forces me to use ReadCube Webreader, which fails every time to load my article. I also cannot download the article. I have full permissions to view the article, but everything but the first page is blurred out. I just want to use Adobe PDF Reader like I used to, but I cannot figure out how to disable ReadCube. I have toggle this setting https://www.readcube.com/epdf_settings, cleared my cookies, turned off my addblocker, but nothing works! If I use Safari, which I really don't want to do, it works just brilliantly. Please help.
My add-on HTTPS Everywhere was interfering. It can be disabled by clicking the HTTPS Everywhere Icon in the browser window, and selecting the red-highlighted processes that are being encrypted by clicking on it. This is a bad answer to my question, because I'm not entirely sure how this has fixed the problem, but it has worked.
Our web browser plugin has worked in all IE versions and still works fine in IE9 and IE10 but in IE11 the plugin is not even recognized and listed as an add-on. It's as if IE11 no longer supports ActiveX.
NOTE: this questions is asked as the developer of the plugin and not the end-user who might need to correct IE settings. So suggestions for how to detect ActiveX or how to adjust a browser settings to allow ActiveX are useless here.
We assume that what we need to do is make adjustments to the ActiveX structure so that IE11 on Windows 8 approves the plugin so that it can be available to the user at their discretion, ie: list it in the Add-on Manager.
A sample project and test page can be downloaded from here - http://addmine.com/temp/EPM_project.zip
Surely there is a workaround but what do we need to change?
As of IE11, add-ons are supported only for IE on the desktop. If you're running the Windows Store experience of IE, then your statement about IE11 not recognizing the plug-in is absolutely correct. This article shows how you can have this experience prompt the user to open the page in the desktop experience of IE, which will support your plugin.
Having said that, it's entirely possible that you do change your plugin to support changes to the Windows 8 security model. Here are a couple of links to get you started:
Supporting enhanced protected mode (Note that this is part 1 of a four-part series)
IEInternals: Understanding Enhanced Protected Mode
IE Blog: Enhanced protected mode
Hope this helps...

I read that early builds of Chrome supported ActiveX, but was later restricted to certain MIME types (for support for say Windows Media Player). I then read Google was going to enable ActiveX strictly for the Korean market. How do I (re)enable this in Chrome?
Our web based product relies on ActiveX controls from 3rd parties to play custom video. This limits us to IE. We'd love to support Chrome also, but find it impossible w/o ActiveX support.
There is a proprietary plugin called "Neptune" which says that it will allow you to use IE Tab functionality in Chrome on Windows.
Meadroid do this because they have ActiveX controls which they have written and they want them to be able to work in any browser, and they explicitly mention Chrome in the list of supported browsers for enabling ActiveX with this.
There is also a modified version of Chrome, called ChromePlus, which includes IETab, among other extra features.
I've not used either of these personally, but they look like they'll do what you want. I'd be interested to hear if they work out for you, as I know of other people who want to be able to use IEtab in Chrome :)
anyone who says activex is less secure then NPAPI is crazy. They both allow the exact same access. Yes I've written both. The only reason people think activeX is insecure is because 10+ years ago IE had default settings that allowed a remote site to auto download the plugin.
maybe this new Chrome extension helps:
ActiveX for Chrome
https://chrome.google.com/extensions/detail/lgllffgicojgllpmdbemgglaponefajn/
This could be pretty ugly, but doesn't Chrome use the NPAPI for plugins like Safari? In that case, you could write a wrapper plugin with the NPAPI that made the appropriate ActiveX creation and calls to run the plugin. If you do a lot of scripting against those plugins, you might have to be a bit of work to proxy those calls through to the wrapped ActiveX control.
I'm not an expert but it sounds to me that this is something you could only do if you built the browser yourself - ie, not something done in a web page. I'm not sure that the sources for Chrome are publicly available (I think they are though), but the sources are what you'd probably need to change for this.
http://wiki.answers.com/Q/Does_Google_Chrome_support_ActiveX
Google Chrome comes with an ActiveX
shim, as part of its default plugin
array. So Google Chrome features at
least partial support for ActiveX
controls (as do many non-Internet
Explorer browsers). I can't find
information as to whether or not this
includes support for ActiveX security
certificates or the like, nor if/where
such plugins can be controlled, within
the browser.
..... Note that to enable the plug-in
you must run Chrome with the following
switch " --allow-all-activex" So in
shortcut that is used to start up
Chrome, add this after "Chrome.exe"
I downloaded this "IE Tab Multi" from Chrome. It works good! http://iblogbox.com/chrome/ietab/alert.php
