Every time I update Firefox all my settings and preferences are changed. I have considered all the ways that Firefox can be setup and the way I work most efficiently is described below. I would like to be able to update without having to tinker with my settings every time. - When clicking a link in a page that I am viewing, I like the new page to appear in the same tab in the same browser. I usually don't want it to appear in a new tab, or new browser. When I do want it to appear in a new tab or browser I like to hold Alt or Ctrl to do that when I need it. When I update Firefox goes back to opening new tabs or browsers. Also, it seems inconsistent with this tabs vs. browsers. - There are certain search engines that I have deleted because I don't like the results and they can interfere with other search engines like DuckDuckGo, but on update these reappear. - When opening a new tab by clicking the "+" I want my home page to appear in the new tab. I have made that setting several times but updates keep undoing it. I forget what it is called, but it is the feature where favorites appear in boxes spread out over a whole page that keeps coming back. I don't find this or equivalents from others such as MS tiles very useful. When I open a new tab almost every time I want to perform a new search and my home page is set to the landing page for my favorite search engine. There is more but this I hope give you an idea of what is happening. If you can please refrain from telling me that I have to like new tabs and browsers when clicking links or that it is faster or more efficient I would greatly appreciate it. It may be true that a lot of people like what I don't, but I have given it careful consideration. Everyone works differently and does different kinds of work. What suits one doesn't necessarily suit another. I wold very much appreciate any insight on this. Thank you. Current Firefox version 41.0.1 Windows 7
