The Bugbug bot thinks this bug should belong to the 'Firefox::Preferences' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Hi iBenny,
What sorts of things are you dragging from FF to MSWord? What custom settings in about:config were reset by the upgrade?
To D&D text/links/images
I've put this setting to "false" and the upgrade reverted it back to "true"
browser.launcherProcess.enabled = true
It has to be "False" in order for D&D to work...

Hey mhowell, does this sound familiar, where the launcher process on Windows can cause issues with inter-application drag and drop?
There is a Mozilla ticket over this issue here : https://support.mozilla.org/en-US/kb/windows-administrator-launcher-process-error-fix
but it talks about playing with Windows UAC setting that I don't want to play with. Not that I'm afraid to do so, just because it is a longer process than adjusting the about:config appropriate setting as stated above.

This pref is intentionally reset during updates, because it was never intended to provide the user with a toggle switch for the launcher process, and using it that way is not supported; it was introduced when the launcher was still experimental and was only ever meant to be used to facilitate those experiments.
The support article you've linked to is correct about what's going on, and I would echo its recommendation to reenable UAC, as that is probably the only fix available for the drag and drop issue that does not also compromise your security (disabling the launcher process makes it easier for malware and other apps to inject code into the browser). If that is absolutely not possible for some reason, the article provides another alternative, but note that it is less secure (it makes it easier for web-based malware to infect your system). Those are the only supported fixes for this issue.
