After updating firefox to 3.6.4, fiddlerhook no longer allows you to disable firefox traffic. It will always show up in fiddler. Is this a known issue with the new way firefox is handling add ins?
Are you seeing this problem with Adobe Flash requests? FF3.6.4 has a new feature that runs add-ons out-of-process, and I think they have a bug where the proxy setting from the main process isn't properly propagated to the background add-on process. I don't know if that's been filed in Mozilla's DB.
Restarting Firefox should resolve the issue.

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 :)

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.
https://addons.mozilla.org/en-US/firefox/addon/firepicker/
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.
IE and Chrome offer window.performance.getEntries(); to get information about performance of entities in a webpage.
In both FireFox and Safari, this command is undefined when I try to use it from the console.
So, my question is: what is the alternative in FireFox and Safari for this functionality?
EDIT:
I'm using this command via Javascript. Hence I need an alternative also for other browsers.
CanIUse says something for resource timing (which is part of what youre asking): http://caniuse.com/#search=resource timing
Also it says
This feature can be enabled in about:config, search for dom.enable_resource_timing flag
By default it is turned off, you'll have to ask your users to switch it on manually, or to write a plugin for this purpose
Now window.performance.getEntries(); works fine in Firefox, but the problem remains for Safari.
Firefox runs my website significantly slower than IE or chrome. When I check the network tab, I see that 235ms is spent blocking. No blocking is reported for my site in chrome, and no blocking is reported in firefox for other sites, like google or amazon. It also has a much higher receiving time than chrome.
Its my understanding that blocking occurs because the browser has a limited number of connection that it can make:
What is meaning of 'Blocking' in Firebug Net Panel?
Here's an example of a website blocking before the document: http://thehill.com/ (sorry in advance for the politics). The blocking on this site doesn't always occur (it does on my site) and is about 1/10th the length of the blocking on my site.
Shouldn't the browser always have all its connections available when it tries to download the Document? Why would firefox be blocking on the document and not chrome, and how can I fix it?
Firefox has it's own http proxy settings. IE and chrome take proxy settings from windows settings. Please check if there is some difference between your FF and IE settings.
Next thing you can do is creating new, fresh profile in FF (make sure there is no addons installed) and trying again.
try making your javascript calls asynchronous. My wild guess (with no codes provided that is the only thing possible) is that you have some javascript call that is blocking. try optimizing and debugging javascript, maybe that will help you see where did the blocking appear.
I've got this weird bug. The progress bar in IE's bottom-window status bar keeps incrementing very slowly after an Ajax POST. At least that's where I think the problem is.
How can I tell what the hell IE is doing that's causing the progress bar to keep going? In FireFox, I would just look at the Console tab in FireBug and see what's up.
I turned Fiddler on but it doesn't pick up any HTTP requests or responses being sent.
What can I do in IE?
I'm not very experienced in Web debugging but you might try the Developer Tools that come in Internet Explorer 8. It's under the Tools menu, or just hit F12. I think the Profiler tab may be helpful. I had heard somewhere that the IE8 Tools were created to mimic Firebug's feature set as closely as possible.
An another tool for checking HTTP requests is the Debugbar
This might not help if Fiddler isn't picking anything up, but HttpWatch is a great http request debugging tool for IE.
I don't think there is a problem here, earnestly. IE has a bug where it shows that a request has not yet been completed when it has. This has been around for a while now, and I have tested my own applications against it. There is nothing happening and there are no connections waiting for a response, yet the browser still thinks there is an open connection.
i recently discovered this tool for earlier IE versions which can be used in combination with the IE debugger for network profiling and more behind the scenes debugging
http://www.ieinspector.com/httpanalyzer/
open IE ...thn press F12 ...here you will get many menus..to debug script choose "SCRIPT" option..and start debug...and if there is any error on page...thn u will get on Console option..also see on attach image...
Using Firebug v1.20b7 with Firefox v3.0.1 I use firebug a lot for web devlopment.
I have very often the problem that Firebug won't show its web console for seeing the POSTs and GETs. I can view all the other tabs, including the NET tab that gives me a lot of the same information that the CONSOLE tab does.
Curious if anyone else has had this problem, and maybe a solution, or maybe this is a bug of Firebug.
There is a limitation in firebug (or rather, in firefox iteself), which will be fixed in one of the newer Firefox releases.
The bug is caused by the fact that firebug needs to send data a second time to monitor what's going on in the connection.
There's now a special API hook in the firefox trunk that should prevent this workaround in the future, so that firebug can really spy on what's going on :)
Well, 1.20b7 is technically a beta version of Firebug. :)
I've had problems with certain features off and on, but a restart of Firefox seems to fix it more often than not.
