more options's firewall-lite for instance appears for me to install instead of what I selected - Flashblock. Another of it's products appears instead of AdBlock Lite.

This is via the Install button in the list of add-ons after searching. IF expand the Details of the add-on the Install button at the bottom works fine, I have my add-ons now.

Running OS X 10.6.8 - Snow Leopard with Sophos 9 installed.

Is that happening when you attempt to install Flashblock from here?

I was unable to reproduce the issue just now, uninstalling Flashblock required first. The normal way - via the Search results Flashblock - Install The Install button at the bottom of the Details. The suggested link - I didn't see any difference.

That means I see no problem at all now.

It is BACK - the mybrowseraddon - com's firewall-lite webpage appears on SYNCED computer's Firefox after logging into Sync.

Firewall Lite is not installed in the source Firefox - the others are new installs. What is going on? The only obvious remnant of this junk is a bookmark, in case Mozilla asked for the link.

First, shut down sync to prevent spreading.

Clean out the other computers.

mybrowseraddon - com's addons permeat the Firefox List. "Posted by" name differs. icloud-notifier, Facebook Disconnect etc.

Sometimes the Developer website is mybrowseraddon - com or it could be http://add0n - com ---- yes a zero used, or other sites. It is an open source developer site.

If I select Flashblock in the LIST of Addons, FlashBlock should be installed and NOT Firewall Lite.

I have no evidence the addons are malicious or even just lousy.

I go to SYNC to a new install of Firefox on a Clean Install of Windows 10 and what do I get but that Firewall Lite phishing crap as an open tab, not actually installed.

Includes a form to submit bugs, - EMAIL required.

At least I cannot locate this JUNK in Add-ons Manager.
