Looking good.

Finally, no more googling to find out what each setting does. Very handy when you want to get under the hood.

very convenient

Only 15% of config are covered (without extensions*). I don't think it's that hard to find all description and integrate them to addon.

(very late reply...)

True, but then this would be a different extension. I created this to get at the comments left in by the developers that were otherwise inaccessible not to enumerate every one. For the rest, use:
http://kb.mozillazine.org/About:config_entries

If I ever get around to tinkering with this again I'll probably add a context menu option to link to online documentation where available.

Very useful. Many tks to Dave G.
Suggestion: Could You make this brilliant addon work also for Thunderbird?

Very useful, should be integrated by default Rated 5 out of 5 stars

Very useful if you come across about about:config from time to time. Should definitely get integrated into firefox by default.

Brilliant addon! I don't see why mozilla didn't include these descriptions in the first place, afterall, they made a site ref. Thank you for the time saved!

Mozilla developers wrote the source comments this extension shows, but not the online reference. MozillaZine is an community supported site, not the official Mozilla support site. Though not Mozilla run, it is often recommended and is currently the best source of information on things of a technical level between what's on Mozilla Support (SUMO) and the Mozilla Developer Network (MDN).

Я джва года ждал этот аддон ;)

Good addon but description field is too long.
It will be good to have a separate base of about:config settings
clients can update the local copy from server
for example it can be stored as json (on user's machine)
{"pref.name":{short:'short description','detailed':"blah blah blah",
values:[
{val:0,descr:'disables superfeature'},
{val:1,descr:'enables superfeature'},
{val:2,descr:'enables superfeature but some subfeature is disabled'},
]},....}
if the pref supports only several correct values show a drop-down menu with them on editing (though there must be a way to set the pref directly).

Also the base should contain info not only about firefox prefs but also about addons ' prefs

not what this extension is for

The whole point of this extension is to simply and quickly access the information about the preferences that is already shipped with the Firefox releases. It is way outside the scope of this project to rewrite it to load up a massive, meticulously maintained, remotely updated, fully translated, database of every single preference for your browser and all extensions. This extension is not a complete substitute for looking up things online yourself. http://kb.mozillazine.org/About:config_entries

Brilliant Rated 5 out of 5 stars

Great idea. Thanks for your work.

It would be even better if you could use your own file, and describe ALL the entries.

A must-have for serious hackers who are not afraid of “voiding their warranty” by setting preferences yet still prefer to know what they are doing. :-)

Great!!! Rated 5 out of 5 stars

I'm always looking up about:config properties and what they do. This add-on saves me a lot of time!

Rated 5 out of 5 stars

Small and smart. Some people think when others dance! I mean, it's seem so obvious and yet no one wrote this add-on before :)
By the author of FlagFox, by the way.
Nice!

Extremely useful and enlightening! Works perfectly. A must-have for Firefox tweekers.
