Greetings. I have Windows 10 and Firefox for my browser. Has worked very well for many years but now I have a problem with Google search. Normally when I do search on Google and get the results I can click on a link and it will open in a new window(tab). 3 days ago I noticed that when I clicked on the link after search the site would open in the existing window. I checked my settings in Firefox and they appear to the untrained eye to be normal. I did go to the settings in Google and noticed that the "open results in a new window" was disabled. I enabled the option (no save function was available) and did a search again. This time it worked as I had hoped opening in a new window. This worked for a few hours and then once again noticed the problem. I went back to the Google settings and once again it was disabled. I enabled it and then worked fine. It continues to disable this function to open results in a new window after a few searches. Not sure if this problem is with Google or Firefox. I apologize for the length of this question but am trying to provide as much info as possible. I very much would appreciate any assistance regarding this .. Thank you
