Thank you aaFn and good people at Mozilla for all you effort!

I loved Alice0775, for making available "Go Parent Folder" and "Show Parent Folder" for all the people with more than 10 pages bookmarked.
When you search something in bookmarks, being able to actually go(not just open it, in a tab), where the found bookmark is located, is a MUST have in every default FF.
When I search for something in bookmarks, sometimes I just want to find(because I do not(want to) remember all the hierarchy) the subfolder in which it is, so I can add a new bookmark there. Same logic goes for deleting something and tidying up.
Another missing, but important thing in bookmarks, is to search for FOLDER NAMES too. Same logic as above...say I want to add a website link to bookmarks, but cannot remember the exact name of the folder where I put the similar links. To my knowledge, FF does not search in the names of the folders, it just searches in links. Has this folder name search in bookmarks, been done in those WE? As a workaround for this drawback, I have created a lot of false bookmarks which I named exactly like the folders.
About the translation...I would be happy to translate in my native language(which is not English). Use github translation system(page).
I did not see an email address, where we can talk to you about this extension...maybe you do not want to get bombarded by spam..I get it, although talking through reviews is more difficult and not efficient, and for us non developers, having to use github is not the most convenient way to exchange messages.
Cheers!
