[FF30] I can't disable this toolbar because I CAN'T FIND IT! even with about:config! :(

I am one of the 746,665 users of Chris Pederick's legendary WEB DEVELOPER addon:

I'm not quite certain why this happened but at some point I apparently also installed: __________Mark Bokil __________ID: 167804 __________web_developer_toolbar-1.0-fx.xpi

. . . which is truly bizarre given that I haven't (and never will) install an addon that is still in Beta (the icon appearing yellow instead of green). What is important is that Bokil's addon is interferring with a number of my other addons and effectively disabling my user settings.

I have: Looked for this man's addon in my FF Addon tab. Looked for this man's addon in my toolbar customizations. Looked for this man's addon in every single Options tab (including sub-menus). Searched in about:config to see if this man's toolbar shows up anywhere. Emptied my History and browsing cache.

Having rebooted with this man's addon clinging to me like a VIRUS, I: Binary-searched this man's identity hidden in an xpi extension I may have saved to my hard drive. Explored any Addon Suites within which this man's addon might be buried. And finally (and this is the living END) completely uninstalled Grease Monkey.

Friends, I am here to report to Mozilla that this man's code is so perfectly HIDDEN I may have to uninstall Firefox altogether. Please advise me.

This extension adds a button to toggle the built-in Developer toolbar (Firefox/Tools > Web Developer; Shift+F2)

Web Developer Toolbar adds a button to open the Web Developer Toolbar available on Firefox 16+.

 <toolbarpalette id="BrowserToolbarPalette">
  <toolbarbutton id="webdevtoolbar-24" label="Web Development Toolbar" tooltiptext="Web Developer Toolbar" type="button" oncommand="DeveloperToolbar.toggle();" class="toolbarbutton-1"></toolbarbutton>

Are you telling me that this toolbar/GCLI (whatever it is because I can't find it anywhere) thing is hard-coded into FF?

And I have no way of removing it? Oh wow. I'll have to uninstall Firefox because this is one of those threshhold issues relative to my continuing to use Firefox. It's a significant conflict so please let me know.

Thank you for helping me with this cor-el, you are always so helpful.

If the invisible extension does not appear on the Add-ons page in the Extensions section, where/how are you finding it to be installed?

You didn't install the forum's Troubleshooting extension, but you can view the list of extensions it captures on the Troubleshooting Information page. Either:

  • "3-bar" menu button > "?" button > Troubleshooting Information
  • (menu bar) Help > Troubleshooting Information
  • type or paste about:support in the address bar and press Enter

Scroll down a bit to the Extensions table. Is it there?

Forgot to mention: if you find the extension in the table on the Troubleshooting Information page, do a global search of your hard drive for the ID to discover where it is installed.

The Developer Toolbar that opens if you click the button that the extension adds is one of the built-in developer tools and thus can't be removed.

Observe these two graphics:

I CAN'T REMOVE EITHER, WHATEVER THEY ARE. I don't want the (whatever it is) with the blue icon/black background that was the issue for my commencing this thread in the first place. But wait, it's breeding . . .

In the already-crowded field of addons containing the words "Web" and "Developer" I now have not 1 but _2_ utilities that I cannot locate and cannot disable (thank you cor-el for a mercifully candid response).

I'm sure there is a loyal community of Firefox users who appreciate and use the Mozilla Developers toolbar; and as for this other man's annoying app, I cannot locate where it's hidden and cannot disable it. The both of them are interferring with my use of Chris Pederick's Addon by virtue of the ubiquitous and growing overuse of the word "Developer."

Mr. Pederick's addon has over 740,000 users at last count, so it seems to me that Mozilla needs to man up and admit that, short of introducing a long-overdue set of strict labeling conventions, at a minimum your developers should release a patch/utility to assist end users such as myself who repeatedly confuse the (now) 3 of you.

I don't want the Mozilla-engineered (whatever it is) feature that cor-el has just informed me is hard-coded into FF30 and will respectfully uninstall Firefox and check back from time to time to see if anything has changed. Good luck.

Hi merry widow,

The "console"-like icon that comes from the "Web Developer Toolbar" extension is associated with this ID:


Can you find that folder on your system and remove it?

Regarding the name Web Developer, it is a little confusing to see two entries on the Tools menu:

  • Web Developer, for the built-in tools, and other extensions that add themselves to this menu
  • Web Developer Extension, for Chris Pederick's toolbar

But you might not need to use the Tools menu if you usually display Chris's toolbar, and it has a distinctive icon you can add to your main toolbar to toggle it on and off.

If you find the built-in tools displaying unexpectedly, there may be conflicting keyboard shortcuts. You might be able to fix that by disabling the built-in features in about:config (the preferences start with devtools, e.g., devtools.debugger.enabled).

The first image shows the toolbar button that the web-developer-toolbar extension adds. The second image shows the built-in Developer Toolbar.

You can uninstall the extension in "Firefox/Tools > Add-ons > Extensions", but you can't remove the built-in toolbar. You can only hide this toolbar via its close X or via the (Web) Developer menu. If you do not want to use built-in features like the developer tools then don't use them. You can move the Developer con from the "3-bar" Firefox menu button drop-down list to the Customize palette.
