OK Rated 4 out of 5 stars

Pretty good idea, but it needs to be fiddled with to have a decent behavior. It is very hard to use when reading an article, for example, where it randomly jumps between an English text and local text. Solved by switch off and use button. I would have much preferred something like select text and right click - a menu bar could display the converted sum; much like Converter does and Google Translate addons - they are less intrusive.

But, that is not the reason it has 4/5 stars, it's because the parser goes bananas at some points. It has translated $3 as "$3-$300" which then converted to 995 RON (10 RON ($3)00) which is unusable. I checked the HTML, it is plainly stated " $300 ", no magic.

When it is stable, it will deserve a 5 star status, objectively and a 4 star status for being intrusive, subjectively.

Also, Firefox complains it was slow to start when a tab has ~10 prices or more on a page.

Great addon, but is it possible to add Japanese yen (JPY) and Chinese yuan (CNY) as a source currency? There are hundreds of asian online shops nowadays.

Maybe in the future releases I'll add them... need to think about that

This is one reason, I will never switch to Chrome. The add-on ecosystem which Firefox has can never be replaced by chrome. Kudos to the developer for this simple yet extremely useful addon. 5 stars without an iota of doubt !

Good tool. Just needs more markup options Rated 5 out of 5 stars

This works really well for me after some tweeks. (It took a while before I located and right-clicked the Options button at the lower right of the FF window instead of the similar on/off button at the top.) Now the only thing missing is the option to set markup at any percentage (or at least include 1%).

just added more values to the markup, please install 2.0.9
You can also open options from the add-on manager

bug Rated 1 out of 5 stars

Adoro este add-on, ele é meu preferido. Mas a última atualização (2.0.6). Está fazendo desaparecer o ícone da barra de add-on superior diretia. Isso acontece toda vez que reinicio o firefox (21.0a2). Firz a remoção completa do simple currency utilizando também (eCleaner mais recente) e fiz uma nova instalação limpa da versão recente 2.0.6 mas mesmo assim ainda faz desaparecer o seu ícone quando reinicio o navegador. Por favor adoraria que conseguisse consertar isso, por favor, por favor, por favor, obrigado! e um abraço! - (Brasil)

This review is for a previous version of the add-on (2.0.6.1-signed). 

If the toolbar icon disappears the right click on the toolbar and customize the toolbar by dragging the 'simple currency converter' icon to the toolbar.

If the button is disabled (blurred) on every Firefox restart then go to the options and check 'Enable conversion on Firefox start'

Please update your review if this helps, thanks

[Very] Effective with a Bug [2] Rated 3 out of 5 stars

Since FF 19.0.2, I noticed Firefox would randomly hang completely if there's Amazon/Ebay sites opened along with gmail (not sure if it's the only way that hang FF). Disabling the extension prevents the problem. Too bad, it's currently my favorite currency converter addon ...

Instant results, easy to use Rated 5 out of 5 stars

So cool to see actual figures on the page you're looking at without having to click or go anywhere. The icing on the cake is a toolbar toggle button allowing for instant enable/disable. Great add-on, would so love to find a similar tool for detecting & converting timezones, so if anyone knows of one please let me know!

Problem solved.Thank you Dev

My earlier post:
It has a bug. I used to love and use currency converter version 1.0.13 for FireFox, and it does what it is supposed to do, but it really slows the browser down, especially when trying to load Google Images or vids. With this add-on enabled, Firefox sometimes stops altogether and says (not responding). This problem goes away as soon as I disable the converter. It must be scanning for prices continuously, (even when disabled) and I informed the dev, but I guess there is no way to turn it off completely. What a shame! :(

Effective but with a bug Rated 4 out of 5 stars

Edit: after contacting the dev, within a day he fixed the problem for me. It still isn't perfect when activated, but when deactivated, it won't run the background process that caused the problem. And that's good enough for me. Great support!

Scc is a great extension that has helped me with converting prizes on sites as eBay and Amazon.One bug keeps persisting though. When visiting the google image search site, firefox begins to run very slow and hangs intermittently. This only happens with scc installed. Whether the extension is enabled or disabled doesn't matter; the problem keeps persisting until the extension is removed. After that the problem is over.

Really helpful addon Rated 5 out of 5 stars

I didn't even expect it will turn out THIS useful and convenient to use this addon. So tiny and so helpful. Literally changed the way I see online stores or just texts with sums. The toggle shortcut is also a great idea. My must have addon from now on )

Rated 3 out of 5 stars

Certainement un bon add-on, très discret, convertit instantanément les prix affichés sur une page dans la monnaie désirée. Cependant pour mon premier test sur une page tous les prix en $ présents sur les cotés (publicités, promos etc), ont bien été convertis, mais pas le prix du produit de la page "produit". désinstallé.

Very cool add-on! Really. Simple and does exactly what it's supposed to do (well, almost).

The only small issue i found is the text "selling for less than $.70/GB" in a page, which was not converted to Euros as i expected. I'm guessing it's due to the missing 0 before the dot.

Other than that, excellent (so far).

PS: Updated rating to 5 stars for the immediate bug correction. Excellent work!

Не знаю где отвечать ( Rated 5 out of 5 stars

Поставлю хорошую оценку, потому что когда нормально работал - то это супер плагин. Вы у меня спрашивали на каком сайте тормозит. Отвечаю - только что проверил на версии ФФ 11.0, и тоже самое тормоз на версии ФФ 14.0.1. Даже при выключенной конвертации тормозит при перелистывании в google reader. То есть при нажатии на кнопку "следующая непрочтенная новость" - зависает секунды на 2-3. Когда новостей пару сотен - то убивает наповал. Долго я вычислял плагин, который тормозит. У меня их штук 50. И нашел таки ( Почему-то Ваш плагин не дружит с гугл ридером.

Да, вы правы что тормозит, надо там переделать немного, посмотрю или возможно что то сделать

Does What It Says On The Tin, Developer On Hand Too Rated 5 out of 5 stars

Installed this a while ago, used it from time to time and find it does what it should. Very useful app.

Recently found a bug, reported it and had a fix released within the hour. Full credit to the developer.

doesn't quite work Rated 3 out of 5 stars

Nice when it works, but it could not convert Australian dollars (or Fiji dollars, or New Zealand dollars) to US Dollars. How to convert from other "dollars" to US?

This review is for a previous version of the add-on (1.0.9.1-signed). 

Yes you are right, I need to update the extensions description.
It only converts from US $, Euro, pound and rubles.
It is not possible to convert from other currencies
