Is there a way to optionally run a 32-bit version of Firefox on my 64-bit Windows 8 platform to enable some functions on a specific website?

Posted

SVAR (The Swedish National Archive) demands a plugin, djVu, for viewing scanned documents. When it still refused to work after installing djVu it turns out that my webreader should work with 32-bit and my new pc is delivered with 64-bit Windows 8. Is there a way to shift between 32-bit and 64-bit Firefox?

And longer answer, Firefox 20 for Windows from Mozilla.org is only 32-bit.

The WOW64 part in your Firefox 20 useragent shows you have 32-bit Firefox on 64-bit Windows.

So, maybe, or probably, my problem with SVAR has nothing to do with Firefox after all. Thanks anyhow!
