Unfortunately it is not a replacement for the extension you are thinking of ;-)
As already mentioned in the description, it is replacement for "Rights to Close" legacy extension.

Can you provide any more details? Your OS, Firefox version and an example website where it didn't work for you?

Thanks for the clarification :-)

I updated my response for the comments where the users might have asked for left double click on the tab header itself.

Apparently that is not supported in the new WebExtensions architecture used by Firefox.

Even otherwise, the main difference between using double-click-on-tab-header (other extensions) vs double-right-click-anywhere-in-the-page (this extension) is that in this extension, the user doesn't need to move the mouse at all when closing the current page :-)

Thanks for your feedback :-)

In case you are asking about double left clicking on the tab header itself, I believe that is not supported in the new WebExtensions architecture used by Firefox.

:-)

Double click is a common gesture which is used for various other useful purposes, so that wouldn't be a part of this add-on.

EDIT:

Thanks for the feedback. Can you provide any more details about the problem you are facing so that it can be fixed ?

EDIT:
- The intention of this extension is to support the use-case of those users who open and eventually close a lot of tabs while working with mouse
- Double right click is a simple and unused gesture, hence it fits well with the target use-case of this extension
- The context menu shows up because that happens as soon as the first click is registered. Apart from that, it is not possible to control the native context menu
- You mentioned "Page contents often interfere with the functionality of the right-click". I do not see how that affects the purpose of this extension
- You mentioned "Something that works with Firefox tabs would be ideal". Assuming that you are talking about the tab header:
a). Apparently it is not supported in the new WebExtensions architecture used by Firefox
b). The user would still need to move the mouse up to the tab header. While the purpose of this extension is to avoid the need of moving mouse at all for closing the tab :-)

Thanks for the feedback :-)

EDIT:
Currently it leaves the context menu on the screen, due to a bug for Firefox-on-Windows with apparently no workarounds :-/
I'll file a bug report to Firefox.

You mentioned that it doesn't work on some pages like Facebook ... Can you try again after updating to the latest version of this extension which I have published just now.

If you are still facing the issue, kindly create an issue at https://github.com/webextensions/close-tab-by-double-right-click since it is easier to follow there :-)

EDIT 2:

EDIT 1:

Double left click (and also triple left click) is very often used for selecting text. Apart from that, various websites use double click for some common UI/UX operations. Hence, in my opinion, such conflicting shortcuts/gesture shouldn't be used.

But, in case you still want such a functionality, you can modify this extension to create a new one by following these steps:
- Go to https://github.com/webextensions/close-tab-by-double-right-click
- Download the code as a zip file by clicking on the "Clone or download" button
- Extract the downloaded zip file
- In the extracted file close-tab-by-double-right-click.js , modify the line which says:
if (e.which !== 3) {
MODIFY THIS LINE TO
if (e.which !== 1) {
- Reference: The above mentioned line can also be currently seen at: https://github.com/webextensions/close-tab-by-double-right-click/blob/master/extension/scripts/close-tab-by-double-right-click.js#L9
- After that, you may zip the files inside the extension folder and use that to create the add-on via https://addons.mozilla.org/ for your use. While publishing, if you wish to use the extension for personal use only, then there should be an option for self-distributed add-ons, you may want to select that.

Hope that helps :-)

Thanks for the feedback, I guess you might have double right clicked on the tab or tried to use it on a native page or the Mozilla add-ons site itself (it doesn't work for those cases due to security/architecture reasons). This extension closes the active tab when you double right click anywhere on the page.

Thanks for the feedback :-)

Edit:
I'm done with the analysis and it is a bug for Firefox-on-Windows with apparently no workarounds :-/
I'll file a bug report to Firefox.
Till then, I don't see any other alternative approach while sticking to double-right-click-on-page gesture for closing tab.

Thanks for the feedback. Are using Firefox on Linux ?
I have added a fix for Firefox on Linux, can you update to the latest version and test again?
