My experience with this add-on is horrible. When I first started the add-on, it went to settings. For some strange reason, the developer makes it incredibly difficult to GET BACK TO THE SETTINGS. My new tab goes to either a blank page or the firefox homepage. In firefox settings, the new tab area says that it is controlled by this add-on (new tab override). (I have everything else correct, "custom url" and "new tab override" in the appropriate places.) Unfortunately, the only way to change the new tab page is to get back to settings. THEY SAY all you have to do is press Shift + F12 to get to settings. That couldn't be less true, at least for me. It goes to the standard F12 html debug window. Then they say that, "it is also possible to open the settings interface by entering newtab settings in the address bar or from the menu entry in the tools menu). I was able to do that once, then it disappeared! You'd think that he would have a link to get to settings or there would be an easy way to change this SINCE IT'S THE ENTIRE PURPOSE OF THE ADD-ON. Very frustrating. I see why only 78,000 people could stick with it. When it works, it's great. Problem is: it only works when you first set it up. There isn't any new tab icon anymore, I have no idea why it disappeared. It's probably Norton or something, I have no idea. It's quite frustrating. Avoid the frustration--that's my advice. Oh yeah, the icon on the taskbar USED TO ALLOW ACCESS. It disappeared, too. It's glitchy as heck and not worth the trouble. Avoid.
