Firefox 4.0b8 worked on CentOS 5.5, but 4.0b9 has a problem with the revision of the C++ library and won’t run out of the box. All is not lost though, because you can use Fedora 9′s C++ library instead as follows (some of this may need sudo/root access):
1. Unpack the Firefox 4.0b9.tar.bz2 somewhere (e.g. /usr/local/firefox). With the “en_GB” release, I throw in a “dictionaries” sub-dir under there with en-GB.aff and en-GB.dic in there (and en-US.aff/.dic soft-linked to the en-GB ones) otherwise, sadly, Firefox 4 uses US spellings on what’s supposed to be an en_GB release
2. Download this 32-bit Fedora 9 libstdc++ RPM and unpack it with this command:
rpm2cpio libstdc++-4.3.0-8.i386.rpm | cpio -i –make-directories
3. Move the unpacked shared library into /usr/local/firefox thus:
mv usr/lib/libstdc++.so.6.0.10 /usr/local/firefox/libstdc++.so.6
Note: It’s “usr/lib/libstdc++.so.6.0.10″ above (i.e. the unpacked tree from the RPM, not the system /usr/lib tree) – do NOT put a leading slash there!
4. Run Firefox 4.0b9 with:
Or you can install last stable release of firefox from Here and compile with installations instructions on readme file.
