New items in the Add-on Bar


Suddenly a series appeared in the add-on bar: JS, J, F,SL, C ,I, A, CS and I don't know where they came from. What's going on? My other computer doesn't have them.

I am using FF version 18.0.2

Its may be a malware.

uninstall unwanted addons

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

Further information can be found in the Troubleshoot Firefox issues caused by malware article.

I have tried several time to reply to your email with more info but it never gets to you. Here's what I sent: Subject: Re: iamjayakumars posted an answer to your question "New items in the Add-on Bar"

Well, I ran two Anti-virus programs (Super Anti-Spyware & NOD32) on all files on drive C: and found only one Trojan which was removed. Also ran your RootKit program - nothing found. No change to FireFox. Here's what my Add-On Bar looks like:

   (see uploaded image.)

Holding the cursor over each of the "newbies" I get: JS Enable/Disable JavaScript J Enable/Disable Java F Enable/Disable Flash SL Enable/Disable Silverlight C Enable/Disable Cookies I Autoload Images A Enable/Disable Animated Images CS Toggle Style These turn red when I click to disable. I haven't tested all but CS works and switches the screen to show the HTML of the screen. When I look in "Customize Toolbar" I see the same things except they are red. I can move these to the toolbar but cannot move the blue ones from the toolbar to the "Customize..".

Now that I think about it, I think these may have appeared about the time I installed ReminderFox, but I'm not sure.

I have looked at all the Extensions and Plugins but none look like they might relate to this.

One other thing I notice different about my FF - on my wife's and my other computer the tabs have a small box on the right to click for a new tab. But that has been missing on my computer for a long time. Not a problem - Ctrl+T works fine. Once I removed FF but did not kill all the user stuff so reinstalling did not correct the situation.

I am looking forward to your evaluation.

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

Interesting,I don't recall installing Quick Java. Did it arrive with Reminder Fox? Anyway, I have found it useful - particularly to block cookies when some site wants to dump a bunch on me.

Thanks for the help.
