Webkit and safari running in 64 bit mode should have a different user agent string (or some other property) so that the running mode can easily be detected by javascript. Maybe do something like IE does by adding an x64 in the user agent string.

This is not identifying the underlying OS architecture, but rather the browsers own running mode if it is applicable to the platform, ie if the browser has a 32 bit version and 64 bit version and a user can choose which to use.

Why would this be useful?

Now I understand that this above bug was fixed, but Apple is taking it's own time to release official Safari patches. In the mean time it would have been nice to detect browser running mode and filter out the 32 bit safari and let people use 64 bit safari for apps that are experiencing the math bug.

Why not just try the calculation once, and compare the result to expected one?

(In reply to comment #5) > Why not just try the calculation once, and compare the result to expected one? Doing that already. But having a user agent suggesting the running mode makes life easier, just incase the kind of calculations needed change if future issues are different. Thats why was requesting this as an enhancement. Both IE and FF do this on windows (and linux) platform. FF doesn't do it on the Mac because they decided to stick with what Safari does. https://bugzilla.mozilla.org/show_bug.cgi?id=489586

Is it something needed now that macOS is just 64-bit and we don't have Windows Release? Or it is something needed for GTK or other builds? Appreciate if someone comment and tag / mark this bug accordingly. Thanks!

We do not want to leak details like CPU bit or other architecture details.
