Форум поддержки Thunderbird

I have been using Thunderbird for many years, and really like it - until two recent updates (sorry!). I am running Ubuntu 22.04, and Thunderbird 115.4.1. One now has a column taken on the left which is unnecessary, and a section at the top which is above the menus with e.g. File... but I would like my File menu at the top, as it used to be. The second issue is more frustrating - the search facility, where one can find the emails being sought, allows me to search by many options, and I was able to display the results sorted by subject, size or my normal was by date, but I never use the message threads as that is rarely of interest, and I can sort on that using the message subject if needed. Now, when I search the results are ONLY in the message threads, and if I try to sort by date, I lose all information, and the ONLY option is to see the messages by thread which is no use to me! How can I restore good old Thunderbird - the version I enjoy using (or have the functionality I had restored)?! Many thanks,
