Does Not "Duplicate"

[LRand]

Today is Thurs, Feb 11, 2016.
I've had Duplicate Window 2 installed on my Firefox for perhaps a year or so and it's been working flawlessly (used to use "Clone Window", but after a system clean-up due to ID-theft and then-current Firefox download/install, "Clone Window" appeared to be no longer available. Found "Duplicate Window 2" and installed).

For 5 or so days now, {ctrl-N} generated a new FF window but brings up my Home page rather than a clone of the FF URL in focus.

Yesterday afternoon:
Removed Duplicate Window 2, Ran Norton360 full scan, a CCleaner Registry scan, Windows disk cleanup, and Windows disk defragmenter. Restarted Windows. Launched FF, cleared cache, and tried to remove any Duplicate Window 2 cookies but found none. At that point reinstalled Duplicate Window 2.

{ctrl-N} still producing new Home Page FF window.

BTW - I'm still running Windows XP - SP3

Does anyone have any suggestions?

Thank you,

Hi!

What is your Firefox version?

[xabolcs]

@LRand, it seems newer Firefoxes broke it.

While the fix arrives please use Firefox ESR as a workaround!

Downloaded FF ESR, installed, and tried. Works like a charm!

Meanwhile, I have my FF set for automatic updates. Will that overwrite the ESR components?

Thanks,
LRand

Hi!

Thanks for feedback!

Firefox 44 has breaking changes. The next major version of ESR will be based on 45, so it would also break the extension.
That means this workaround will last to 2016-06-07.
The minor versions like 38.7 and 38.8 of Firefox ESR will work.

I was also sad about Duplicate2Window not working anymore with new Firefox. Meanwhile I use "Clone It". It's not as nice as Duplicate2Window is, but it fulfills it's purpose by right clicking on a tab and choosing the appropriate action.
