Bug 1043612 has been landed. However, the following in-content subdialogs do not remember its size. * content > Fonts & Colors > Advanced... * content > Languages > Choose... Persistence of the size of the Fonts subdialog is useful for ja locale. See Bug 1148923 [ja] Subdialog default width of in-content preferences is too narrow in ja locale

Those dialogs don't have the persist attribute specified on the <window>, therefore they don't get persisted. We could look in to changing that though. http://mxr.mozilla.org/mozilla-central/source/browser/components/preferences/fonts.xul http://mxr.mozilla.org/mozilla-central/source/browser/components/preferences/languages.xul

Looking at this more, these dialogs don't resize well and weren't designed to be resizable.

Did we want to uplift this?

Comment on attachment 8592210 [details] [diff] [review] Patch Yeah, we should uplift this. Approval Request Comment [Feature/regressing bug #]: in-content preferences, shipping in v38 [User impact if declined]: some dialogs are resizable that weren't resizable before and they don't scale with the resizing [Describe test coverage new/current, TreeHerder]: manual testing, been on m-c for over a week [Risks and why]: very low risk, just disables the resizing of only three dialogs [String/UUID change made/needed]: none

Comment on attachment 8592210 [details] [diff] [review] Patch I think this UI polish bug is safe and simple enough to take late in Beta. Beta+ Aurora+ ni Florin to add in-content pref UI resizing to his team's list for exploratory testing if time permits.

Comment on attachment 8592210 [details] [diff] [review] Patch [Triage Comment] Should be in 38 beta 8

Verified on Windows 7 64bit, Ubuntu 13.10 32bit and Mac OSX 10.9.5 using Firefox 38 Beta 8 (buildID: 20150426174329) and the following in-content subdialogs aren't resizable: - Content tab -> "Advanced" (Fonts) - Content tab -> "Colors" - Privacy tab -> History -> Use custom settings for history -> "Settings for Clearing History" - Security tab -> Passwords -> "Change Master Password" Additional exploratory testing related to in-content pref UI resizing is done under general testing for "In-Content Preferences" feature.
