Description of problem:
I am using hardened_malloc on Fedora 39. It works perfectly fine for everything apart Firefox. Firefox uses its own allocator "jemalloc" and somehow these interfere.

I built firefox with this:

ac_add_options --enable-optimize --disable-jemalloc --enable-project=browser

the result works perfectly fine, I verified it uses hardened_malloc and ran the Web Basemark with it, without a single issue.

Now it should also be possible to still use the regular build, and still use hardened_malloc if the OS preloads it.

ac_add_options --enable-optimize --enable-replace-malloc --enable-project=browser

this way a LD_PRELOAD=/usr/lib64/libhardened_malloc.so firefox will use it instead. In the current situation it does not launch and I get memory issues.


Version-Release number of selected component (if applicable):
latest F39

How reproducible:
always when LD_PRELOAD ing hardened_malloc. I use the Secureblue kinoite-laptop-userns-hardened image.

Steps to Reproduce:
1. use secureblue or manually apply these changes to use hardened_malloc
2. run firefox in a terminal
3. now compile it yourself with that argument and run it again

Actual results:
Firefox does not work when using hardened_malloc, because it doesnt seem to be built with allowing to replace the malloc

Expected results:
If the OS does LD_PRELOAD then Firefox should also use that. The easiest solution would be to apply this build argument.
