Anyone know a way to set up Google Chrome so we can open development servers on? Instead of setting it as the general default browser?
In other words, I don't want my development servers to open up on Safari (that's what I have at the moment) each time I run my local development server, but I don't know how not to do that unless I switch Chrome to be my default browser (which I don't want it to be my default). Is there a way I can write in my .bash_profile to do this (automate the process of only opening Chrome for development purposes)?
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.

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/

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.
I have implemented the google analytics tracking code for a website.
I need to check if its working fine or not in safari 10.0. I cannot buy MAC now to get safari 10.0, instead finding ways to simulate safaro 10.0 with any addons?
I heard about the User agent switcher extension available in chrome/firefox from which we can simulate the browsers and its versions.
I am unable to find safari 10.0 in available user-agent switcher extensions.
Can anyone suggest me how to simulate safari 10.0 with any better extensions please?
If you are looking to change the user-agent string, that can be done using Developer Tools for most modern browsers. Check out this full guide from HowToGeek.com
Excerpt (For Safari)
This option is available in Safari’s normally hidden Develop menu. To enable it, click Safari > Preferences. Select the “Advanced” tab and enable the “Show Develop menu in menu bar” option at the bottom of the window.
Click Develop > User Agent and select the user agent you want to use in the list. If the user agent you want to use isn’t shown here, select “Other” and you can provide a custom user agent. You can find extensive lists of user agents on various websites.
This option only applies to the current tab. Other open tabs and tabs you open in the future will use the “Default” user agent.
I love firebug for helping debug my web apps, as well as seeing how others have implemented there sites. However firebug hinders memory leak testing.
I've just found that FireFox can be launched in safemode which disables all addons, which is great for memory usage testing however once firefix is launched (either samemode or not) all subsequent firefox launches (they all appear in task manager as 1 firefox instance) will use the mode of the first one.
I'd like to leave one in same mode testing some apps for leaks and use another with firebug to develop.
I've tried making a copy of the FireFix.exe and even copying the whole firefox directory but it still launches as one application.
I could always use VirtualBox to create a full virtual PC for this testing but that seams like a large overhead.
Edit
I have just tried the -no-remote switch but it just comes up with "firefox is already running .... you must first close the existing Firefox process.... "
First close all your Firefox instances. With all instances closed, run firefox via the "Run..." dialog on windows, typing "firefox -p". It will open with the profile manager, where you can create multiple profiles with different configurations.
After creating your profiles, just run you "main" browser using "firefox -p" and select your "main" profile. To open another instance using a different profile, run Firefox using "firefox -no-remote -p" and it will prompt the profile manager again, so you can choose a different profile.
I would like develop on add-on for Firefox , which combine with other available add-on's and make new add-on which providing new features + existing add on feature tooo.
The question is unclear, but here is some information from Mozilla.
How to develop a Firefox extension
and
Developing Mozilla addons
You will find the code of all installed extensions in the firefox profile folder. In my vista machine, it is located at C:\Users\<ur name>\appdata\Roaming\Mozilla\Firefox\Profiles\<randomstring>.default\extensions\
Unzip the jars and learn the code, edit as per your needs and restart firefox. Remember that when firefox automatically updates the extension, ur changes will be overriden. If something goes wrong, start firefox from cmd with -P switch to create a new profile or goto safe mode using firefox -safe-mode and uninstall and reinstall the extension from its website.
