480260 - disable Clear Recent History when in Private Browsing mode

Status: VERIFIED FIXED

(Firefox :: Private Browsing, defect, P2)

Description

[Mike Connor [:mconnor]]

spun off from bug 463607

We don't have a good safe/compatibility-friendly way of fixing this for 3.1, so we're going to just disable the feature in PB mode for now.

Attachment: disable CRH in onEnterPrivateBrowsing, enable in onExitPrivateBrowsing

This patch disables the CRH command when we enter PB mode and disables it when we exit, just as we disable/enable the Import... command.

Funny thing was that users can also call CRH from their Preferences menu. I couldn't figure out an easy way to disable/enable that button (especially since you can invoke PB mode with the PrefPane open) without attaching an observer, and I didn't want to attach an observer, so instead I did the logical thing and questioned why the heck we still have a "Clear Now..." button there when we also have it in the menu. Gavin, Mossop, Johnath and I couldn't think of a solid reason, so I just removed it (and the associated command from privacy.js).

Let's see how mconnor feels about that!

This is the same patch as attachment 364466 [details] [diff] [review], only with a simple test added.

BTW, Beltzner, do you want the Clear Now button in the preferences window to be removed on trunk as well?

Thanks, Ehsan! I was trying to teach myself how to write tests, so this is helpful and informative.

I think so. Perhaps we should just remove the "branch only" from the comments and land this fix on both trunk and branch, and then fix bug 463607 on trunk only at some other time.

The decision to remove the "Clear Now..." button has also been approved by faaborg and mconnor, so I think it's valid on both trunk and branch.

No, thank *you* for picking up my slack here.  :-)

Yes, I think that would be the correct thing to do.  This way we could land this on trunk first and let it bake a little before landing it on 1.9.1, in order to stick with branch tree rules.

OK.  We need a Litmus test for that then, setting in-litmus?.

Patch + test

we don't need to null check every single item, only things that aren't part of the hidden window on Mac.  I think the previous patch is probably okay, will review that.  (We actually discussed the null checks when beltzner was writing the patch yesterday)
