SCIM starting whenever I start Chrome and Firefox

I swear I don’t remember installing anything of this sort, but now, whenever I start up Firefox or Chrome, this weird “SCIM” toolbar pops up, and interferes with everything I type. Typing spaces and tabbing to the next field is a hassle and pain, it weirdly underlines text I just typed (but then doesn’t underline it if I backspace or whatever), and it takes up screen space (albeit not much).

Even if I kill EVERYTHING to do with SCIM (using the command ‘lsof | grep scim’, then ‘killing’ every process to do with it), it ALWAYS comes back when I use Firefox or Chrome.

I’ve no idea WHAT is happening, but I don’t like it. I can hide the panel, but then there’s an ugly icon in my system tray still, and all the other annoyances while typing are STILL THERE.

So far, I’m just right-click, quitting it every time it pops up. But I’m getting sick of it, and I just want it to STAY down.

What do I do?

I don’t know any simple way to disable SCIM for a given user,
but if you don’t need it just uninstall packages beginning with scim* and skim*.

If you wonder what this thing is:
SCIM is used for text input in many languages - Japanese, Chinese, Greek etc.
I use Chinese pinyin input method from time to time.

If that doesn’t interest you, I think, it’s safe to remove these packages.

If I remember correctly, Skim is the KDE front-end. But I’m getting the GTK frontend. I do not have Gnome installed.

It’s one of those things that intruiges me, and that I might use in the future, but I just don’t want to use right NOW. There a way to get rid of it without removing it?

Well, most of the threads I find via Google look something like:
“cannot disable scim” or “scim starts automatically” with no solution.
If I knew how to do this, I would disable it for one of the users in my system too,
but I use it sometimes myself. And I am just to lazy to actively search for solution.

So uninstall seems to be the easiest answer.
That doesn’t mean that you cannot reinstall it later.
It is quite trivial task with package management.
