I started using Midori and Claws-mail, until then. These programs are pretty good, though they lack convenience and features. I supposed any graphical Internet browser that has SpiderMonkey as a dependency may work for sites that need Javascript.
I'm wondering if the fixed packages have been made available. When I test installing Firefox and Thunderbird, before the confirm prompt, the amount of dependencies don't show up, including the ones that require uninstalling and reinstalling everything else. It's like dependencies associated with that messed up my graphics display. LLVM association with Mesa, gl or another dependency. libdrm needed to be reinstalled, and it took down my drm-kmod installation for FreeBSD. Another time, it seemed to bring down my drm-kmod install from packages.

The process will require 640 MiB more space.
Proceed with this action? [y/N]:
In short, the latest packages from Latest are: Firefox 100.0_1,2 and Thunderbird 91.9.0_2. I wasn't paying attention to the version number that failed, but these could be different default option and patched builds. It didn't ask for the latest LLVM and Rust, and the seemingly perpetual uninstalls and installs that come with that. Also, the defaults for port building of Firefox and Thunderbird didn't have the LTO option set mentioned earlier.
Late edit: comparing to the comments before, they seem to be the same version numbers. Perhaps they changed their default options, made patches and made repository packages from them since then.
