I have used avant browser for more than 3 years and became a fan ever since. However, more bugs appear in later version (maybe to my computer) and causing irregular problems, so I sometimes have to switch to firefox. Anyway, I upgraded the avant browser version to 123 from 46SR and found the function of hold right click+middle mouse button to close the window stopped and can't activate. I tried to change the avant preference of mouse back and fore and got no result. Please help me fix me as it is such an important function to me.
