Removing data created by GM_setvalue

[Rob]

Afternoon all,

When I use the GM_setvalue function I can see the additional entries
in about:config .

Is there a way to completely remove them? Are there any problems with
allowing them to build up in a users browser?

You can't remove them through your script, but you can:
* set them to null
* check "also uninstall associated preferences" when uninstalling a script
* in about:config, right click the preference and select "reset"
* Remove prefs in bulk by editing prefs.js
<http://kb.mozillazine.org/Prefs.js_file>. Exit Firefox, back up that
file, then run it through grep -v or similar.

As for problems, I've heard accounts of scripts that read a lot of
preferences getting sluggish. Otherwise, they take up space but
shouldn't affect performance unless you're running out of memory.

It is not clear whether this is what you want to achieve, or if you
just do not want to have them displayed in about:config. It should be
clear that carrying out the steps suggested by Lenny effectively
amounts to same as definitively deleting those preference values.

I think there are plans for switching to the new storage schema
mozStorage [1] supported by Firefox 2, based on sqlite. If this
becomes true some day, it will be possible to keep about:config and
GM_Set/GetValue apart from each other.

First, there are two different new storage APIs. Yes, one of them is
sqlite-backed.

I submitted a patch to the dev list as a proposed GM_ api for sqlite
access. The GM devs must be busy, because not a lot has been happening
over on the dev list recently. I haven't heard yea or nay for anything
I submitted.

I'm alive, but not doing much contributing to GM lately. I have a
new job and recently launched a new site. Anyway, um, probably still
a few weeks before I can get around to GM stuff. :-/ Sorry.
