as an example In ancestry.com if I select DNA, and then DNA matches, I will get a list of hundreds of matches. If I go down through the list and select one match and click on it, I can investigate the detail. Then I want to tab back to the list. Most of the time it goes all the way back to the original DNA matches screen. Sometimes it doesn't but not often. If I have done a search on a surname, when it goes back, I will have to do the search all over again. Time and resource consuming. I tried it with Windows 10 and Edge and it works properly. Then I tried it with Google Chrome on both of my UBUNTU machines(desk and laptop) , and it works properly. Its like a back pointer is not being set properly or is being garbagged (used to be a pgmr.) I much prefer Firefox and do most of my work in it, but this little problem is annoying. Thank you for looking at this problem.
