question: discount bank web site - linux+firefox friendly?

[guy keren]

i'm considering switching to Discount bank (www.discountbank.co.il) -
and i want to make sure that their online banking works with firefox on
linux for these operations:

1. viewing the balance.
2. viewing the stock-market portfolio.
3. performing stock/bonds buy/sell operations (including setting limits).
4. viewing information about stocks and companies (both current data,
and past graphs), including searching by name/symbol/stock number,
viewing summary of monetary reports, yields, etc.

if anyone here is doing one or more of these operations successfully
with firefox *on linux* - could you share your experience?

i'm currently working with bank leumi, where all these things work now -
but not all of them worked 1-2 years ago e.g there was a time where i
could only read mail and see my balance and existing portfolio - but
couldn't perform stock/bonds buy/sell operations (the buy wizard would
fail on the last page).

thanks,
