Usefull add-on for better User experience Rated 5 out of 5 stars

Looking for improvement on following use-case:

Suppose my Firefox browser opens with multiple tabs (previously opened). Those tabs are not loaded yet but if I want to close that I need to select each and every tab. While selecting page it starts loading and adding extra delay in closing tab. With feature of this add-on things are much better but still I see unloaded page starts loading and immediately getting closed. The problem I am observing is Firefox is opening next unloaded tab instead of returning to my current tab.

Please note that by default after closing a tab (whichever way you close it), Firefox would focus on the next tab. That's just how Firefox does things, and DCCT does not interfere with Firefox's default.

Therefore what you're asking for is a customized tab-closing behavior for Firefox. DCCT is coded to close tabs faster, but not designed to change post-closing behavior of FF. I'm not convinced that this is the way the majority of people wanted, or that it's worth it to create an option for it. After all, the reason why I made DCCT was that TabMixPlus was too unwieldy with that many options. DCCT does one thing, and it does it well. That's the purpose. Sorry.

Causes pages to not load correctly Rated 2 out of 5 stars

LOVED the app when I first downloaded it but now with Firefox 50.1.0 I've been noticing pages do not load correctly - broken pages, improperly sized images, etc.

This was particularly noticeable on any of the Gawker family sites like Kotaku, etc.

Two questions:
1. Did you disable multi-process in Firefox? DCCT is not multi-process compatible, as noted.
2. How do you know the loading issue was due to DCCT? DCCT itself doesn't do ANYTHING to browser/pages until you use mouse click to activate it. Any loading issue is either multi-process incompatibility problem or other addons.

Add default Firefox animation when tabs are closed Rated 3 out of 5 stars


1) Can you add the default animation when you close a tab? When I have this addon installed, it is not using default Firefox closing animation.

2) Triple click inside page is not working here with Firefox 48.0.2 Windows 10. When I set up 2 clicks, it does work correctly. Why is triple click on a page not working, what is wrong?


1) Sorry I'm not sure how to animate it same way FF does and do not plan to implement that.
2) I'm using 50.1.0 and triple click inside page works fine (it's always worked). Do note that events only work when page is fully loaded, AND other addons might interfere. The issue you faced is one of these two, not DCCT's fault.

Please remove the feature request/bug report review afterward. Thank you.

need extra option Rated 5 out of 5 stars

Great addon! I use it for closing tabs with middle mouse click. But sometimes when mouse pointer accidentally is over link, clicking middle mouse button opens link in a new tab instead of closing tab. Is there a way to disable middle button to open a link in a new tab?

Thanks for the review! While what you want is possible, I must say that given the vast changes in FF, I simply have way too many things to do with my other much more complex addons. So I can't promise anything about adding an option to disable middle click opening links.

However, personally I tried many combinations, and I really like double right click to close inside page. It's also the best way to do it in my DCCT in Chrome. I suggest that you give it a try. I understand that it means that you'd close tab differently inside page and on tabs, but that never bothered me at all and you likely will get used to it.

Works and even better Rated 5 out of 5 stars

Lots of extensions do this job but this one does even better. It allows to double-click-close the last tab to show the enhanced tile page. Excellent.

Thanks! Not sure that's DCCT's feature though. I do think DCCT is the best tab-closing addon - as closing tab can be done both on tab and in page - but I may be biased. :)

Justo lo que buscaba Rated 5 out of 5 stars

4 out of 5
simple to install, easy to set up, quick to use

With high monitor resolution, if you do not like small X buttons for tabs, this is ABSOLUTELY for you!

The only missing thing is removing/moving/minimizing current close buttons.

It's much easier to close the tabs.

A Hidden Gem! Rated 5 out of 5 stars

This is an essential extension that should be built into Firefox.

Many thanks to the developer for creating it.

The only issue is that sometimes Firefox stalls when closing a tab. It's unclear whether or not that has anything to do with this extension, or is just a bug in Firefox.

Since it might just be a Firefox bug, got to give this one 5 Stars!

Not click in page. only trigger the func when I click on tab. Rated 5 out of 5 stars

"BTW if single click on page is implemented, ......"
What if just trigger the func when user single click on tab.

Thank you anyway ! I can implement same stuff just by Script...(muh...the most stupid way...)

and I thought I should learn some about how coding a extension.
Thanks again.

Sorry I forgot all the methods I implemented myself - in fact you already can choose to use single middle click on page to close tab. FF also by default lets you single middle click on tab to close tab. That's also one click. It'd be tricky to change my code to deal with just a single left click.

Essential Rated 5 out of 5 stars

Pretty much an essential addon for me. The only problem I have is that lately using "double right click" to close tab sometimes causes some weird lag. Using double left click or single/double middle click is not so good because you can accidentally close a tab when you're trying to select text or accidentally open links in a new tab, respectively. Maybe the best option is triple left click, I have yet to try that one.

Edit: Raising score to 5 stars after developer response made me realize it's probably just some websites that are at fault. I will investigate which websites lag when using double right click to close tab.

To clarify, the problem is that some websites cause Firefox to stop responding for a good 4-5 seconds when using double right click to close tab. I suspect it's probably the right click menu which makes FF lock up for a few seconds. Sometimes I'm not sure if the problem was my timing or that FF stopped responding and I end up closing two tabs (I have another addon that gives me quick access to "Undo Close Tab" so it's not much of a problem).

Edit2: I confirm it seems to be an issue with FF itself, sometimes a tab takes ages to close even without using DCCT as the closing method. Furthermore I don't remember this issue happening with old versions of FF.

Thanks for the update & upgrade! I did notice that the most recent FF (FF33 and FF34) seems to have some memory management issues - it crashes often on a 32bit machine with 20 tabs or more. And it crashes often when using the new Google Maps, which sucks BTW compared to the old one - seems to me the only purpose of the new Google Maps is to mess up FF as Chrome doesn't crash dealing with it.
With that said, another phenomenon I noticed was that when I close a tab (whichever way I close it, either DC on tab or DRC on page or TLC on page or Ctrl-W), occasionally half of the old closed tab's content shows on top of the newly-in-focus tab. It's a very weird phenomenon that happens on my Win8.1 64-bit machine(s). This is confirmed not due to DCCT because simply switching tabs by SLC (single left click) on a tab could lead to the same super-imposition problem. This happens when memory usage is high. So I suspect what you saw is a variant of this issue, and it might be due to FF rather than the websites. But this is just a hunch, I can't reliably reproduce the issue to file a bugzilla report.

Previous reply:
Hmm, I've never seen this issue though. So if you double click on tab to close, it doesn't lag, but double right on page it lags? Did you notice if the lag is consistently on some web pages but not others? I suspect some pages might be doing something with mouse events, although that's still hard to explain how a page eventually end up being closed, just that the closing gets delayed.
If you can find a way to reproduce it - like it always happens on a certain page - send me URL. Also let me know which OS, FF versions are you using. I suspect it's OS related as FF behavior for right click/context menu on Linux and Mac was different than Windows before.

Thanks ! Rated 5 out of 5 stars

I was searching for floating close button, didn't find, but this one can replace it, so useful, thanks a lot ;)

Works fine on FF 29.0.1 !!

Great! Rated 5 out of 5 stars

Excellent add-on! It would be more perfect if it can avoid closing app tabs.

Keep up your superb work. Thanks a million times.

Finally Found It Rated 5 out of 5 stars

Bin looking for this for quite some time. Total time saver and frustration saver for a shaky mouse hand trying to click a little "x".
Even close the browser on single tab. Again, no little "x"
Thank you Mingyi Liu!

希望能做些别的事情, 只用来关闭, 好像不合适, 可以定义成刷新页面

Yes, but on the other hand, I used to use TabMixPlus, for 2 reasons only. 1: double click to close tab. 2. adjust tab width. The issue is, why would I install such a big addon that slows FF down for these two trivial reasons? That's why I made this small DCCT addon to replace it (for myself at least). If I add more and more functionality, DCCT will become more like TMP. You can try check if TMP is actually more useful for you, or find another small footprint addon that does what you want alongside DCCT.

Weird to be excited by such a little thing Rated 5 out of 5 stars

Oops, must have hit the wrong button and submitted an empty review.

I downloaded this little gem and restarted Firefox about 15 minutes ago, and have been gleefully opening tabs just experience the joy of zapping them closed. And I haven't even played with the settings yet!
