InformAction Forums

I have the same issue, below are extensions. I am on Windows 7 64 bit, FF 56.0, Dell Optiplex 3040 with 8GB memory

NoScripts
Cookiekeeper
Fireftp
Flagfox
Tab Mix Plus
Web Root Filtering Extension

Also gone is status line across bottom that shows number of scripts blocked, maybe nothing is getting blocked?

I have restarted FF and disabled and enabled NoScripts and that didn't change anything.

UPDATE: Started FF in safe mode and the restarted in normal standard mode, did brings icons back and status line across bottom of screen showing blocked scripts. It was almost acting like NoScripts really wasn't even running prior to starting in safe mode and the restarting??? Did not have NoScripts options when I right click + Customize on the toolbar.


Similar to the problem I had with 5.1.1 a couple weeks ago, but then I was blocking scripts then and had the status line on bottom of screen, just no icons on top. Then for what ever reason one day the icons were back, no updates or safe modes.

Hope this helps in some way...

Current Extensions:
NoScript 5.1.2 (of course)
mHeaderControl 1.0.4 (webex)
uBlock Origin 1.14.14 (webex)

8-bit

Also been getting this, on win 7 64 bit.

Worth noting:

Only other add-on I have installed is ABP.
When it started happening, it was triggered by an update. On the upgrade page noscript mentioned that I wasn't running the latest version, which I thought was odd - then I checked the url and the update path pointed to this -> https://noscript.net/?ver=5.1.1&prev=5.1.2 i.e 'updating' to 5.1.1 from 5.1.2. I checked noscript in my add-on settings and it claimed I was using 5.1.2, so I realized something was wrong then came to check the forums, saw this thread and realized that my icon was also missing.

The safe-mode suggestion appears to have fixed it for me as well.

Safe mode trick worked, thank you. But extensions list as requested:

Tamper Data 11.0.1.1-signed.1-signed true {9c51bd27-6ed8-4000-a2bf-36cb95c0c947}

Just experienced this myself and found out it was because the latest FF update had not applied like usual.
That's probably why the safe mode trick worked,because it triggered the FF update.
So,not a bug with NS

Safe mode restart is working so far.

Firefox Version: 56.0

Extensions:

• AdBlock Plus
• Safe Browsing, Version 4 (temporary add-on)
• Ubuntu Modifications

Same problem here with 56.0 (64bit) on GNU/Linux (Gentoo ~AMD64)

Starting in Safe mode once fixed the issue. Interesting note - I was shown "after upgrade info page" when starting FF after Safe mode (it was shown twice - first time when symptoms started, and a second time after start/exit cycle in Safe mode). Some timing issue leading to incomplete addon installation?

No, it is not a problem of FF update mechanism (as suggested by Verteron » Sat Oct 14, 2017 4:58 am) as I do not have automatic updates and I haven't had time to compile new FF for a while.

Icon reappeared after bouncing Mozilla browser- no Safe Mode needed.

Safe mode trick worked.

Hi,

I am running Firefox 56.0.1 (64-bit) on Arch Linux and was affected by this bug.
The following fix worked for me:

join2 wrote:

1. Firefox menu > Help (?) > Restart with Add-ons disabled
2. Click the [Continue in Safe Mode] button
3. Restart the browser again normally: NoScript UI should be back now

Here is my addon list, as shown in about:support: Thanks for this easy fix, and thanks for developing NoScript

Neither safe mode nor running FF as admin brings the icon back here.

Add-ons:
* NoScript
* Priv3+
* VideoDownloadHelper

The first method worked, hope the fix is permanent.

The list of my extensions from about:support as you asked:
