I am using Firefox 110.0.1 on my Mac running High Sierra 10.13.6. I did an Onyx clean up and an now when I go to use the search bar on the toolbar none of my search choices will display. Once I key in whatever I am searching for the search choices will sort flicker quickly on and off, but not display long enough for me to select one. Only when I hold down the Command Key will the choices appear for me to select one.

Also, if I type an long entry into search bar and then go to edit or modify the entry, I cannot scroll forward to the end or beginning of the entry. Using the < or > will take the cursor only to the beginning or end of the visible text and no to the true beginning or end of what is in the box
