You do not have a thing ticked to send info to us so I have no idea what other Extensions you are running or what else could cause this issue. Is this the Speed Dial your talking about ? https://addons.mozilla.org/en-US/firefox/addon/fvd-speed-dial/ Is 23.3.1 the current version you are running ? Think you need to take a look at their page (at bottom) as says something about rolling back a version or something while they work to make it Firefox 57 Compatible. As to when they did that. So it maybe they did this prior to version 56 that you are running. Note that we are not affiliated to Speed Dial, just host their page only. Fyi: Current version of Firefox is 56.0.1 and update will get to you or can try from Help-->About to force a upgrade if it will. Fyi: Your Flash is out of date, new version released 4 days ago. https://get.adobe.com/flashplayer/ Direct link scans current system and browser Note: Other software is offered in the download. <Windows Only> https://get.adobe.com/flashplayer/otherversions/ Step 1: Select Operating System Step 2: Select A Version (Firefox, Win IE . . . .)
