Thank you all for your answers.<br>

I suppose the conclusion is that using 32 bits for application is a nice workaround for applications that cause trouble as 64 bits, unless it's really computation intensive (simulations etc.). Maintaining the necessary 32 bit libraries is a not fun, but nothing compared to waiting for this and that binary plugin to work correctly.<br>
<br>
Since the performance issue was mentioned more than once, I'll say that my hunch is that except for real number crunchers (finite elements simulations, video encoding and stuff Orna plays around with) most applications are limited by data starvation (cache misses), so the extra registers allowed for in x86_64 aren't necessary making any real difference. In particular when it comes to browsers, word processors, maybe even video rendering and compilation. But this is really just a hunch.<br>

So 32 bit for Firefox it is. As for the rest, well, who cares, as long as it works.<br>
