Firebug is not working with Firefox version 50.0

Question

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?

Answer 1

Its working. You need to install one more add-on "Firepicker" and restart the Firefox.

Answer 2

Solve The problem by Changing Mozilla Browser Configuration Settings.

1. Open A Blank Tab
2. type about:config in address bar then press enter (click on I accept the risk!)
3. find browser.tabs.remote.autostart
4. select the option then click the mouse right side
5. Turn The Option As False
6. Close the browser for restart browser
7. open browser again, inspect the element. I hope It Works Properly.

Answer 3

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:
