ViewMyCurrency 0.38 released

Friday, 13th January at 4:58 pm 23 comments

New version of the Firefox currency converter ViewMyCurrency in now available.
(Update: it’s now on Mozilla Upate)
Major fix:

  • Pages were getting scrambled or not converting. Fixed: (XPCNativeWrappers in FF1.5 prevented me from storing the original text inside the JS node objects)

Minor Fixes:

  • Increased delay between Firefox startup and exchange rate update to 5 minutes. Made ‘failed update’ error message into a warning. Should be better on a dailup connection now. Thanks Keith!
  • Quote symbol is allowed as thousands separator, for example 1’000. This Swiss site should work now. Thanks Theo!

Update: I’ve summarised all the bugs and suggestions
(I’d love to get more feedback, you can leave comments on that page)

    I just posted and rated your extension on Mozilla Update site. It is good. But since my country is not (yet) part of EU, we are still using our own currency: Convertible Serbian Dinar (CSD). That’s what I am missing and that’s why you are missing fifth star 😦
    So how about an option to add more currencies? Maybe if it is difficult because of live exchange rates, you should add option to create custom exchange rate? That is exchange rate that user should have manually to edit.

    Hi Igor,
    Thanks for your suggestions. I do intend to make it possible for people to add their own currencies but writing the GUI code will take some time. However I’ll manually add CSD in the next few days just for you. I’ll expect the 5th star then 😉

    Anonymous said on my old blog (before I closed it down)
    Swedish Krona should be “kr” and not “ur”

    Thanks! That will be fixed for the next version.

    Another issue with this extension is that it assumes that anything with the $ sign is US dollars (e.g. “$5.50” seems to be assumed to be “US$5.50” by this extension). This means it turns out an incorrect result when the price is in dollars but is actually in another currency that uses the $ sign such as Australian Dollars, Canadian Dollars, New Zealand Dollars etc.

    Maybe you could add a feature so it assumes that $ means US$ except when the website ends with a country domain (e.g. .au, .ca, .nz), so it then assumes that $ means A$, NZ$ and C$.

    Thanks for the great extension!

    John, you raise an excellent point. I intend to add a “locale setter” which will switch between different symbol tables depending on the domain. I’m guessing it will take about a week to write. Thanks for the feedback.

    “Swedish Krona should be “kr” and not “ur””
    Same for Danish kroner. 🙂

  • 7. Anonymous  |  Saturday, 14th January at 5:32 pm

    Great extension, but just one problem- can you make an option for showing your currency in your status bar or not? That would be awesome.

  • 8. Will  |  Saturday, 14th January at 5:51 pm

    Jalf: Danish kroner will be fixed in next release. Thanks!
    Anonymous: Good idea. I’ll add an option to remove ViewMyCurrency from the status bar. I’m a little concerned though, that people might forget that it’s running.

  • 9. Kokojumbo  |  Saturday, 14th January at 6:46 pm

    Among the best extension for FF but I have ONE suggestion. I am from MAURITIUS and our currency is ‘Rs’ and not ‘Rp’. May you please correcnt that mistake and keep up with the good work.

  • 10. Jair Andres Moreno  |  Saturday, 14th January at 7:00 pm

    Its one of my 5 star extensions…. but it have a problem. Im from Colombia and here we use $ to denote COP… in some pages like prices are assumed in dollars so the conversion fail.

    I suggest you to create a list of userpages that doesn’t need the conversion to make this extension perfect.

    A small bug: 0.01 is rounded to 0, if it is converted to 0.00x, instead to be 0.01

  • 13. Rufus  |  Saturday, 14th January at 7:21 pm

    Ah, and I like to have the hide option: my statusbar is already full 🙂

  • 14. Will  |  Saturday, 14th January at 7:56 pm

    Thanks for the great feedback!

    Kokojumbo: I think I’m using the correct unicode character (20A8) for MUR but it seems that it appears as Rp in some fonts. I’ll look into it.

    Jair: I’ll try and add domain detection soon. That should help.

    Rufus: Thanks for the bug report!

    I like the idea of hiding it or removing it from the status bar. Also, another option I would like to have is disable it temporarily, The extensions seems to run a little slow when dealing with very large pages.

  • 16. Jair Andres Moreno  |  Sunday, 15th January at 12:02 am

    If you make click on the status bar (where your currency is display) you disable it.

  • 17. Will  |  Sunday, 15th January at 12:11 am

    I was thinking about making a popup tooltip that highlights my new item in the statusbar and explains that you can left and right click it. Do you think this would help? (it would only appear once)

    Ryan: I think Jair answered your question? (Thanks Jair!)

  • 18. Kim Ludvigsen  |  Sunday, 15th January at 1:50 am

    Very nice extension. But I would actually prefer it the other way round. When I read an english text, I’m thinking in english, so an amount in danish currency is not expected. It would be nicer if the original amount was mentioned first, and the local amount in the brackets.

    And a little correction regarding danish currency. The short form should be kr. and a space. Like:
    the amount of $81 (kr. 500).

  • 19. Ryan  |  Sunday, 15th January at 2:31 am

    Ah, thank you Jair.

  • 20. Erroneus  |  Sunday, 15th January at 4:51 am

    Great extension and looking forward to the next version (danish user :D)

    One thing though, norway seems to be missing from the currency list.

  • 21. Dave  |  Sunday, 15th January at 5:02 am

    Nice plugin! Thanks for the great work.
    I also second Kim Ludvigsen’s suggestion that there should be an option for the local amount to be displayed in brackets after the original amount.

    great extension!

    Unfortunately, the symbol you use for Japanese Yen is different from what is commonly used – the commonly used symbol is the fullwidth Yen sign U+FFE5, while I *think* ViewMyCurrency parses the halfwidth one. Perhaps you may want to add the fullwidth one too. To see an example, try visiting

    Thanks for the extension!

  • 23. Rufus  |  Sunday, 15th January at 4:02 pm

    Also, instead the currency now in use, why not use a coin icon (colored/grey) on statusbar?
