Hope that the fix comes soon. Totaly unexpected for Tumbleweed having an unsolved problem for so long.
Please do not top post.
You need to ask yourself what is unique to your system. I have 3 TW systems that run Firefox perfectly with the latest updates. They are an AMD FX-8320E Eight-Core Processor, an Intel 4th generation mobile i7 *i7-4700M), and an 8th generation Intel i7-8700T. None of them are particularly new.
In particular, you should check if you have an Intel CPU from generation 11 or higher. These have the IBT feature that is not properly handled for all applications. It seems unlikely that this is the problem for Firefox, but if your CPU fits the criterion, then try booting the system with "ibt=off" added to the GRUB startup line. There may be some other "feature" of these CPUs that is not handled in the "lockdown" kernels.

et al: From reading the bug report posts it seems like "they" might be closer to getting it fixed . . . haven't messed with it in my Gecko rolling edition . . . but it does seem like an issue with older cpu's that aren't supporting "AVX"??? I think my machine is Nehalem and that has the problem, "Alder Lake" and newer?? are OK . . . ?? Or download directly from Firefox tar and install it, but then something is needed for the user profile?? A tad bit "messy" F
