I think the following, quote below, from the help page is my problem. I have this one website I use that when I click on a link within the website it is opening a new window with the tab at the bottom. Also, when this happens, I am losing the orange FireFox rectangle, bookmarks and navigation options. How can I set FF31 so that the link opens in a new tab and I keep all my options? I am using Classic Theme Restorer 1.2.3. I also notice that in the new window I lose the ability to use some of the addons. I have two laptops and both are running FF31 and W7. One of them is working perfectly and the other is having this problem. As far as I can tell they are both set up the same. The only difference is that when I upgraded to FF31 they both had difference older versions of FireFox. I also read in the help forum that maybe I need to go back to FireFox 28 to accomplish what I am trying to accomplish. I noticed that when I go under about:config that the version of FF that is not working has fewer available options versus the version that is working. An example would be that the working version has "browser.tabs.onTop" where on the other laptop this is missing. >>>Open new windows in a new tab instead: This option controls whether links from other applications or from web pages which request to open them in new windows are opened in a new window or a new tab in the most recent window. Note: If you have chosen to open pages in new tabs, Firefox will ignore this option and will open a new window from a link if the page author specified that the new window should have a specific size, because some pages can only be displayed correctly at a specific size.<<< Thank you in advance for any help, yeto
