First, one question per thread. This is so people can use the forum search tools to find problems that they may have where the question is already been asked.
We can see that you have Wheezy (Debian 7) installed and so can assume that you are using Gnome. This raises the question as to why you are using some 3rd party torrent client.
As a reformed Windows user I can understand the bad habit of using 3rd party applications. It is a bad habit. There are times, for specific, specialized applications where this is needed. You are not getting the bennifit of a signed package and a gpg protected repository for your packages.
They will always, also, cause problems with version upgrades and should be removed before trying to, say, upgrade to Debian 8 (Jessie) when it is released. They can then be reinstalled of coarse.
This is needless risk and work to take upon yourself. Use one of the many torrent clients available in the Debian repo. You are running Gnome so you should have Synaptic package manager installed. This is a fine gui tool with a search function. Try it, always, before getting 3rd party applications.
You can also use;
Code:
tom@victim:~$ apt-cache search "torrent client"

unworkable - efficient, simple and secure bittorrent client
There are plenty as you can see. I don't know if you checked your menu but you may, under Gnome, have Transmission installed and it works fine.
If not, as root;
Code:
apt-get install transmission-gtk
I will be shocked if you have a problem with that and it doesn't drag in a lot of qt dependencies to your gtk built system.
Also if you look at that list you will see;
qbittorrent - bittorrent client based on libtorrent-rasterbar with a Qt4 GUI
Which is probably the same thing except packaged for Debian, signed by Debian, gpg key protected when installing and with a proper Debian .deb with a functional install script for correct installation. I will admit this may not be in your repo. That list is what is available in my Sid repos.
Whatever you do, I would remove the one you installed. Have no idea how you installed it. If installed with dpkg or with the gui gdebi you should be able to use the command;
Code:
apt-get remove --purge <package name>
and get most of it anyway.
A client working through a web browser is not very efficient and probably not as secure. I wouldn't know about the security personally because I never used such a beast - that is just what passes for common sense for me tells me. I would not bet on how common or sensible that may be.
The important point here is that you should always, if at all possible, use only packages from your distributions repositories no matter what the distro is.
