An example of my problem. In Firefox I have 2 tabs open to a search engine, DuckDuckGo or Google for example In Tab 1 I type "hello" in the search box but do not hit <ENTER>, the text box has focus. I then switch to Tab 2 and type "hello" in the search box but do not hit <ENTER>, the text box has focus. I switch back to Tab 1, the text box has lost focus. I type characters and they go into space. I have to click on the box before entering text. Under IE, switching tabs back and forth does not lose focus on the text boxes. I can switch into a tab and resume typing where I left off. This is the behavior I expect and want. Firefox 68.0 and Win 7 64 bit. This is a problem for me since I often leave a tab open to a search engine, while working in another tab. If I want to check something I go to another tab and have to click on the text box again to get focus and be able to type. A coworker tried it on Chrome and it worked like Firefox. Is there some reason for this? Please don't say it's a bug in IE. Thanks, Ed
