Very good idea Rated 5 out of 5 stars

Good concept and well executed. It's much easier than switching back and forth between the mouse and keyboard.

Amazing and one of its kind Rated 5 out of 5 stars

On FIrefox 50.1.0, all basic functionality is still working flawlessly!!! Allowing you to seamlessly surf without using the keyboard.
---------
Please don't suspend the development (or at least the maintenance of basic functionality) of this app, it's really one of its kind, and I'd much rather not go back to Google Chrome just to be able to use the corresponding extension (called Keyboard Control). I wish the Mozilla community would do sth to support the development of this add-on.
PS: I'd have gladly helped if I were fluent in Javascript (I'm thinking of learning it just for this purpose)
------
my story: I have carpal tunnel syndrome AND a severe chronic elbow injury on my dominant hand, which makes switching between the keyboard and the trackpad/mouse either very slow or painful, depending on my choice.

Doesn't work in Firefox 48.0 Rated 5 out of 5 stars

Anyone know what the problem might be?

Best getting-things-done extension ever! Rated 5 out of 5 stars

This is the extension you need if you are an excessive Firefox user. It saves you tons of wasted mouse-grabbing, mouse-moving and clicking time and it will also make browsing less exhausting. Great idea and great piece of software, many thanks to the developer!

Please fix for Firefox v47 Rated 5 out of 5 stars

This is such a great add-on. Makes life miserable when it doesn't work, like now with v47.

Unfortunately, I see here https://blog.mozilla.org/addons/2016/04/07/compatibility-for-firefox-47/ that FUEL is now deprecated, and also see that MLB's code has some references to `fuel`. I suspect that's what broke.

It looks like MLB hasn't been updated in a few years, and its source
is frozen in Google Code. So I won't be too optimistic that this will
be fixed any time soon.

**UPDATE 2016-07-11:** This was just fixed for FF 47! Thank you, Rudolf!!

A Great Extension! Rated 5 out of 5 stars

The availability of extensions like this is why people choose Firefox!

Eliminates one of the most undernoticed factor that disrupts focus when browsing: mouse. Great addon! Rated 5 out of 5 stars

An unexpected way to make Firefox ~30% faster, and most importantly, to keep myself focused! No more small muscle movements, visual search tasks, and switching modalities that are caused by using/switching to mouse. It's strange, how I now noticed the small pain hidden in each movement I was making, and how nice that it is now disappeared!

It's also much more fun to browse this way. Thank you for making me a happier person :)

Great Extension Rated 3 out of 5 stars

As a programmer i wanted to ditch the mouse, but the browser had always been a problem. This lets me do most of the work I do in a browser without needing a mouse! yay :)

Wonderful Extension Rated 5 out of 5 stars

I'm a moderate keyboard enthusiast and hate having to switch a hand over to operate a mouse. You've helped me almost completely remove the mouse aspect of browsing, sir, and I thank you for that. I'm sorry to hear that development has been suspended, but I hope to hear otherwise in the future. Outstanding extension. I have found no alternative yet that functions as well as this does. I use it in combination with firemacs and these two extensions have made my migration from chromium (chrome) to iceweasel (firefox) incredibly pleasant.

Best add-on I've ever used. Rated 5 out of 5 stars

This has saved me from more pain than I can explain. I just came to this page again looking for a "Donate" button. So sorry to hear development is disabled.

I hope you change your mind Rudolf and stick with it.

Rated 5 out of 5 stars

GRRREAT add-on! Click on anything on page without using mouse.
This finally adds functionality similar to the much loved "access keys" feature in KDE's Konqueror.
And it's so highly customizable to act exactly the way you want. I set it to turn on only when I press ' charachter, and use letters instead of numbers for shortcuts, to and even changed the stylesheel to look eye-candy.
Thanks so much for creating this add-on.
Here's my custom stylesheet if you want to try:

font-family:arial, sans-serif; font-size:xx-small; line-height:130%;
border-radius:4px;
vertical-align:center;
margin-left:2px;
max-width:20px; max-height:10px;
overflow:visible;float:none;
color: #FFFFFF !important;
background-image: none;
padding: 4px 6px;
z-index: 991;
color: #FFFFFF;
font-weight: bold;
display: block;
background-color: #2D2D2D;
position:absolute;

i use css styles from LoL (HaH) addon.
these styles do not spoil the page.
(я использовал css стили от расширения LoL (HaH).
эти стили не портят страницу)

style for id span:
z-index:500;font:normal normal normal x-small helvetica;color:ButtonText;background-color:ButtonFace;border-color:ButtonShadow;border-width:1px;-moz-border-radius:0.3em;border-style:solid;padding:0px 3px 0px 3px;position:absolute;

style for frame id span:
z-index:500;font:normal normal normal x-small helvetica;color:ButtonText;background-color:ButtonShadow;border-color:ButtonShadow;border-width:1px;-moz-border-radius:0.3em;border-style:solid;padding:0px 3px 0px 3px;position:absolute;

я убрал отображение номеров ссылок по умолчанию и отображаю когда нужно (нет мыши под рукой) кнопкой (.) Decimal на цифровом блоке.
ctrl + decimal - делает отображение номеров постоянным.
а ctrl + набор номера - даёт возможность не торопиться при наборе номера активного участка

It's very inconvenient to press numbers as shortcut. I wish it was just Shift+arrow keys like spatial navigation in Opera.

I wish the development wasn't suspended! This extension made me switch back from Chrome.

Only problem is that it misses clickables on GMail.

Wonderful Rated 5 out of 5 stars

If you like keyboard browsing, or don't like mouse browsing, this add-on does a great job.

Only minus I found is that numbering is a bit slow and can mess up layout of pages such as gmail. But gmail is one of the most complex sites out there.

The add-on works out of the box but has loads of options if you want to tweak it.
