Diễn đàn hỗ trợ Firefox

Hello,

I need help i'm using polish language always on many websites.

When i typing letter "ó" which using key combination Right ALT+O always my brower opening "Open file" dialog window. this is annoying always.

Many sites write that it can not be changed?

Why does the browser open this dialog with this shortcut when there is another shortcut for it? Ctrl+O. Why two another shortcut doing te same job?

I have downloaded Firefox 117. I am currently on Firefox 102.15. So I want to transfer my bookmarks to the new version, as well as some recent history. I am unable to find these files to import when using Firefox 117. Also I says that version 102.15 is the most up to date version of Firefox. So this is confusing.
