I'm running PopOS and, after a recent clean install, I'm having some problems with a secondary HDD I use for data storage.

My Partitions

One disk /dev/*sda1 "data" is a 1Tb hdd NTFS logical partition for Basic Data. It is mounted as /mnt/data

One disk /dev/sdb1 is a 500Gb ssd with multiple partitions:

- 1Gb FAT32 /boot/efi /dev/sdb1

- 17Mb Microsoft reserved thing /dev/sdb2

- 150Gb NTFS win10 system

- 4Gb swap /dev/sdb4

- 105Gb ext4 /home /dev/sdb5

- 251Gb ext4 / (my popOS root) /dev/sdb7

- 523Mb Microsoft recovery thing /dev/sdb6

This way my system and apps are in /.
My /home is separate and independent.
And I dump pretty much all my files and downloads in the external drive "data".

Data is mounted like so:


It seems to work ok, except...

First, I can't trash files. I only have the option to permanently delete them (which on my Nautilus is set to NOT be available, btw).

Second, my browser saves downloads wrong.
Edge/Opera/Chrome always ask me where to download files even though I set a default directory and toggled off the option to always prompt me for action.
Looking into it, I noticed that while I set the download directory as /mnt/data/myName/Downloads the browsers interpret it instead as this weird thing /run/user/1000/doc/a0207089/Downloads

Interestingly, Firefox doesn't show this behavior and does everything as expected.
I assume the two problems might be related.
How can I fix them?

This is my fstab:
