Does not work on FF50 with Electrolysis Rated 5 out of 5 stars

Great add-on!

Unforunately it does not work anymore with Firefox 50 if Electrolysis is manually enabled. Could you please fix this?

I am sorry to say that I have decided to retire 4or6 (see the 'About this Add-on' section above). I recommend that you migrate to SixOrNot.

Excellent! Just for my needs - go to my ISP sites through IPv4, since it does not support IPv6, and will not allow for IPv6 through the tunnel broker, thinks that I'm not one of its network.
Thank you so much!

Отлично! Как раз для моих нужд - заходить на сайты моего провайдера через IPv4, так как он не поддерживает IPv6, и не пускает по IPv6 через туннельного брокера, думает, что я не из его сети.
Огромное спасибо!

Great! Rated 5 out of 5 stars

It does all things as expected! Shows protocol and that's it! Allows to switch from 4 to 6 and vise versa.

Nice and simple add-on, provides the much needed information I needed in a clear and concise way.

Two minor gripes though (on Firefox 35): I cannot seem to be able to remove the toolbar button (either through Firefox' Customize, or by right clicking on the toolbar and clicking Remove -- every time I restart Firefox the button is back). Secondly, the context menu of this add-on clashes with the toolbar button's default context menu, both pop up when I right click the menu.

On older versions of Firefox (I think it was before FF 29) you could select where to show the multi color 4or6 icon: in the address bar, in the toolbar or in both. In newer versions the icon can only be in the address bar, but the blue 4|6 icon suddenly appeared in the toolbar. I have had no problems removing it permanently through the Customize... dialog though. The current 4or6 version is 3 years old (which is ancient by any IT measure of time). I am working on a small update that should fix a few things.

Simple and efficient, works very well on my aurora from yesterday.

Broken now Rated 3 out of 5 stars

So, I just updated my firefox to version 29.0.1. And now the little icon which this addon is supposed to display, keeps dissapearing. The only way I can get it back each time, is to reinstall the addon. It's to bad, because this addon was incredibly useful to me when it worked.

On a side note... I'm REALLY starting to get fed up with the way that firefox breaks half my addons every damned time there is an update.

The toolbar element where 4or6 installs the toolbar icon no longer exists. As a result that icon can no longer be shown. The address bar icon still works fine though. You can make that icon show manually by setting 'extensions.4or6@hunen_net.addressicon' to 'true' in 'about:config'.

I intend to update 4or6 if I can find the time to do so. A very demanding office life has prevented this so far. And, by the way, I fully agree with your side note.

Simple, informative, has nice little features - just what I needed. Seems to have some problems with IDN names though (i.e. http://www.sö - not showing remote system IP-s).

Does what it says on the tin and works fine even on latest nightly. Exactly the functionality I needed.

The only worked addons Rated 5 out of 5 stars

show web IP on FF19. Nice!

Very useful Rated 5 out of 5 stars

I need to have the dynamic ipv4 address of my PC in order to access its files from my Android tablet, & this add-on provides that. Works perfectly for what I need.

Addon ONLY displays if the site has an AAAA record. It does NOT accurately detect if IPv6 is actually being used to connect.

To see this for yourself, go to a website that you control (not posting mine for obvious reasons), insert a PHP script displaying the visitor's IP address in the footer, and visit the site. Even if your IPv4 address is shown, the addon will still think you are connected vis v6, which you obviously aren't.

This review is for a previous version of the add-on ( 

Your observation is basically correct. There will normally not be a problem though: a discrepancy between the protocol used to load the page and the icon displayed should only happen in case of a network connectivity problem or a DNS misconfiguration.

Edit: version 1.2.0 shows the actual protocol used to load a page.
