Thunderbird, Unresponsive Script due to McAfee Anti-Spam Add-On.

This started yesterday for me.

If I disable it

Thunderbird operation returns to normal.

The problem occurs (with it enabled) every time TB is opened or mail is fetched. Disable the add-on, no problems.

It seems all of my LS was updated on the 20th, not just this:

Surprised I can't see another report here. Searching the web I did see many old ones from even years ago referencing the same error but with a different JS: number at the end. The solution to those provided me with the fix of disabling the add-on, all pointed to McAfee as the cause.

I don't use the Anti-Spam module nor Thunderbird so can't be a judge, but in this issue I would recommend opening a case with Technical Support, link below.

If at first they can't help, ask for escalation.

Meanwhile of course there may be others who know an answer who will spot this.

I might call support, but they usually will do a re-install first. Many times they do not install the Dell version even if I ask them.

Right now, I'm leaving it disabled, Anti-Spam in TB (we've had long threads on this) is not reliable for me so I don't even use it.

Yes I recall.  You can always tell Support to stop if you see them trying to download the wrong version.  Understood 😉

I use Thunderbird and Anti Spam It has an issue that is to be fixed soon in that emails go into the AS folder but are not shown as being there one has to open the folder to see the list and the total unread emails then shown up. OK not your issue but only current issue I see.

Yes call support but get the Dell version installed  You could uninstall it yourself and reinstall from your account.

Dell's content is way old on AS

I moved this to the actual Anti-Spam community as that's a better spot for it.

Re: Thunderbird, Unresponsive Script due to McAfee Anti-Spam Add-On.

​, from what I can tell I do have the latest Dell release. I know I can uninstall/reinstall the Dell version from my account, but that shouldn't make a difference I would think? Problem started on the 20th of July, the same date most of LS's components were update, so it to me means the update was the problem and that was the latest.

I've NOT been using AS in TB due to the problem you have located. I 'missed' too many emails as they went into the AS folder with no notice of messages being put there.

I'll think about calling in or trying the uninstall/reinstall, but for now I'm OK with the Add-On disabled. Not sure I was to mess with this as I am not using AS anyway?

I might do it anyway to rule out a bad update. If this one component was broken maybe others could be as well and I just have not noticed that.

It must be with the Dell version as mine is fine. Of course 1 way to fix this would be uninstall Mcafee fully and use the beta version you get a few days behind in the engine sometimes but free to use.

OK, I bit the bullet and uninstalled and reinstalled the Dell LS version from my account. As expected, no difference, problem persists.

Slightly different script error though?

Might be because I was on a different tab when I enable the add-on?

As for the Beta, it shows as for a different product, Total Protection, not Live Safe, and not a Dell version? When Support installed the non-Dell version of LS on my PC I had BSOD's. Those stopped once I installed the Dell LS version. Are there beta's for Dell releases?

I'm on TB 45.2.0, and that says it is up to date. I had first reported this to Mozilla and they helped me figure out the add-on that was causing the problem, so I don't think it is TB related?

Just found this, https://productforums.google.com/forum/#!msg/chrome/YKMtrcx7XrM/KVtARPdLCwAJ, I am NOT alone.

Found this too, http://www.solvusoft.com/en/files/error-missing-download/js/windows/mcafee-inc/mcafee-total-protecti..., although old, it points to a specific file, mail-msktbird_3.js, but I can't find it?

Re: Thunderbird, Unresponsive Script due to McAfee Anti-Spam Add-On.

There has to be something going on with the UPDATE process?

I've got a friend with almost the same Dell system and Dell's McAfee. Also using TB. So I used TEAMVIEWER to connect and 'test' their TB. It worked fine? Yes, the Add-On was enabled? Very odd. So I looked at their ABOUT for McAfee and specifically the Anti-Spam. Then compared it to mine:

Why are there TWO different CONTENT VERSIONS? Mine is on the left, the other PC's on the right.

I re-installed McAfee's LS (Dell version) before 8AM today, and it was updated at 10AM... why didn't I get the same Content version?
