Will installing the 64-bit version of Firefox slow down your PC?

I got a new laptop, Toshiba 64-bit, 8gb memory, 1tb hard drive, running Windows 10. The Firefox version is 43.0.4.

I think I installed Firefox 64-bit, at least I intended to. I can't find anywhere that tells me if it's 64 or 32 bit. I looked under Help but that was a misnomer in this case.  :-)

The access using Firefox seems extremely slow compared to the 32 bit version on my old Windows 7 laptop. It is also a Toshiba, 64 bit, 8gb memory, and 500gb hard drive.

I don't know if the problem is the Firefox 64-bit or the Windows 10. Whichever, it is makes snail mail look fast. By being slow I mean I can click on URLs to open maybe 10 webpages and it frequently takes 10 to 15 minutes, yep, minutes, to open them and sometimes I have to refresh them because they haven't opened in that length of time. I have both laptops sitting side by side accessing the same wireless router, and the speed difference is extremely noticeable. Looking for suggestions.

The browser that you used to post this question reports that you are using the 32-bit version of Firefox.

The useragent of browser you used to post this thread: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0

The WOW64 means it is a 32-bit application running on 64-bit Windows.

See www.mozilla.org/firefox/all for the Win64 Firefox.


Note if you do use Win64 Firefox, only the 64-bit Flash Player and Silverlight plugins are white listed to run. If you want to use other Plugins in Firefox on Windows, you need 32-bit Firefox and 32-bit Plugins.

Well, that answers that question. Some time ago I installed the 64-bit version but when I was having so much fun (NOT) with Windows 10, I think I must have uninstalled it and went back to the 32-bit version since I'd used it before and knew it worked well.

And I'm assuming that the 32-bit version works the same (just as fast) in Windows 10 as it does in Windows 7. Am I assuming correctly?

It looks like Windows 10 is the culprit when it comes to the slowness problem. And that's what I expected. But I had to ask about Firefox to rule it out.

Thanks for all your help. I'll go back to fighting the Windows 10 demons.  :-)
