719321 - Update list of migrated IE prefs

Status: NEW

(Firefox :: Migration, defect)

Description

[Justin Dolske [:Dolske]]

Just reinstalled Win7+IE9+FF on my desktop. I chose to migrate IE settings, even though I've only used it to download Firefox. ;-)

Noticed in about:config that a few preferences were set from the migrator. These seem to no longer be relevant, and we should probably look at the other stuff too.

Specifically:

  browser.display.background_color == #c0c0c0
  browser.display.use_system_colors == true

The net effect of these (though I didn't look closely) seems to be to change the background color of new tabs from white to a 1990-era gray. Might make sent to entirely jettison the support for these prefs from the browser code too?

Comment 1

[Justin Dolske [:Dolske]]

browser.visited_color and browser.anchor_color seem odd to migrate now too. In general, I don't think we want to attempt to replicate appearance-related stuff from IE.

network.proxy.type is set to 0 ("direct connection"), the default is 5 ("use system proxy"). [Apparently we changed the default in 3.6, wonder if this was noticed/discussed?]

These (and and the ones in comment 0) seem to be the only prefs actually changed for me.

fwiw, the ie migrator has not yet been rewritten/fixed. Cc-ing Felipe that is working on it.

Comment 3

[:Felipe Gomes (needinfo for replies!)]

The current list of prefs migrated are 95% at http://mxr.mozilla.org/mozilla-central/source/browser/components/migration/src/nsIEProfileMigrator.cpp . There are a few prefs with special handling that do not appear on that list.
But this is all moving to JS very soon. I think on the migrator rewrite patch I'd like to have most of the current prefs ported, and then we can file bugs for dropping some of them afterwards.
I'll add more details here soon

Yeah, doing the C++-to-JS port and then fixing bugs like this seems reasonable to me.

Comment 5

[Marco Bonardo [:mak] (Away Apr 25 - May 5)]

the js port is done and the 3 settings in comment 0 and comment 1 are not imported anymore. The new migrator contains some url reference to msdn reporting some known registry keys.
The scope of this bug is actually to figure out which other settings we may be interested into, to add those to the ones we already import.
