Go to the forum you want to be in where you see the double column layout... double click on the comments section and the screen will zoom into just the single column of the comment. Scroll down and up only in that section. Done.
Clicking on a link will take you to a new tab window and retain that size and orientation. You can return to your previous tab window by clicking the tab window selector at the lower right and selecting the window you want.
I hope this helps.
Thanks. I haven’t tried it your way. I never thought of going to a certain forum — I tend to just read latest posts. I did find that the other browser works very nicely, so I am using it. Going on vacation soon and needed to make sure I could browse FR perfectly!
