If you enable an extension then try to view it's options before restarting,
nothing displays and the extension manager becomes unusable.

Reproducible: Always

Steps to Reproduce:
1. Enable a disabled extension.
2. Right click and select options.

Actual Results:  
Nothing displays and you hear a beep when you click anywhere on the extension

Expected Results:  
The options entry on the menu should not be available until after firefox has
I agree that would make it unusable if it was possible click Options. For me
however, Options is disabled until I restart.

I believe this is due to the checkin for bug 278534 in that the enable disable
functionality in was changed / removed. Also, bug
285544 though different is similarly affected by the checkin.
Ever confirmed: true
This just happened to me in Thunderbird 3/9/05 also.
Robert, would you be willing to take a look at this? I certainly didn't mean to
regress this functionality. If you can't, reassign it back to me.

Not a problem Benjamin, I'll see if I can figure it out.
It seems that the changes that will be introduced by bug 286034 are going to
change the flow and probably process for this to the point that any patch for
this would require a rewrite after bug 286034 is checked in if Ben doesn't take
this bug into account with that patch.
Attached patch patch (obsolete) — Splinter Review
This is a simple one liner. I've tested it with trunk and with the latest patch
from bug 286034.

Though I think the behavior with this patch applied is acceptable I believe it
is different that the previous behavior. With this patch if toBeEnabled ==
"true" the  options for the extension are not available and if an extension is
set to be disabled, then re-enabled the options for the extension will not be
available until after restart. Previously, I believe that if an extension was
enabled, then set to be disabled, then re-enabled the options would be available
without a restart. I don't believe it would be worth the additional code to
provide the previous functionality considering that the scenario is rather rare
and can be easily resolved by restarting.

Clearing review and obsoleting. The patch for bug 286034 appears to have
removed the code that set toBeEnabled along with the other toBe's though they
still exist in extensions.xul (probably a cleanup oversight). Another approach
will have to be taken.

In addition to the options issue this patch also does the following:
* displays the generic about when an item is disabled.
* updates the minVersion and maxVersion of an install.rdf during
_applyVersionUpdates. The case during install still needs to be addressed.
* adds ability to cancel an uninstall by selecting enable on an extension that
is to be uninstalled.
* when enabling then disabling an extension or vice versa an operation will
always be performed even if the extension is already in that state.
* extensions only show as disabled in the EM when they are disabled.
* a couple of JavaScript strict warnings in extensions.js

I don't understand this block:
+      // apply changes to the install manifest if it is already installed and
+      // we can write to the location
+      var installLocation = this._em.getInstallLocation(;
+      var installManifestFile = installLocation.getItemFile(,
+      if (installManifestFile.exists() && installLocation.canAccess) {
+	 this._emDS.setTargetApplicationInfo(,
+					     aRemoteItem.minAppVersion,
+					     aRemoteItem.maxAppVersion,
+      }

Could you explain this?
When an extension has its minVersion and maxVersion changed during an update
check only the extensions.rdf is updated. If for whatever reason the
extensions.rdf no longer exists then the install.rdf is read to populate it and
last I checked it will also uninstall the extension without any user
interaction. This will update the minVersion and maxVersion in the extension's
install.rdf with the updated info to prevent this in one of the cases.

This only handles the situation when the extension is already installed and not
during the install which I have been working on as well. I can remove this if
you'd prefer and add it to the other patch I am working on.

I removed it from the patch and will try to come up with a patch for the other
cases in another bug.

This is a little late in the game for Firefox 1.1a1: let's hold off until after
that release and land this for 1.1a2.

Attached patch Updated patchSplinter Review
This adds a fix one ui glitch when cancelling an uninstall in that the buttons
along the bottom were not updated to reflect that it could then be uninstalled
or updated. It also adds EM_ITEM_CANCEL to nsIExtensionManager.idl which I
overlooked since they aren't used anywhere as of yet.
