Hi boldeagle, Firefox can't disable your Kaspersky security software, only the add-ons that Kaspersky adds to Firefox. And if you have one of the more recent updates for the 2016 version, they got rid of several of their older extensions and are installing a new one that definitely should be signed and verified.

Could you share with us your current list of enabled and disabled extensions? The simplest way is to view the full list 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/Return

Then scroll down to Extensions and just below that heading, select the table with your mouse and copy it (either Ctrl+c or right-click > Copy), then paste it into a reply (either Ctrl+v or right-click > Paste). It will look a bit messy, but we're used to it. Thanks.

Good e.

Here are the results (unfortunately in Italian.........)
