Firebug toolbar button is always shown deactivated since Firefox 51.0.1


Recently my Firefox got updated to version 51.0.1. Initially it was showing some reminder check (I'm not clear with that) related to Firebug, but I ignored it. Now, the Firebug toolbar button is always shown deactivated.

Inactive Firebug button

I've reinstalled Firebug several times, but the result is always the same.

Is there any compatibility issue? How do I activate Firebug?


Solution

  • There is a solution to use Firebug version 2.0.18 in the latest version of Firefox (this time 51.0.1).

    To enable the old Firebug:

    In the address bar, enter about:config and find browser.tabs.remote.autostart. Set it to false.

    Also set browser.tabs.remote.autostart.1 and browser.tabs.remote.autostart.2 to false.
