Firefox Install Problem
It (appears to at any rate) uncompressed the Install files, writes a log file in the temporary directory (normally C:\WINDOWS\TEMP\FF_TEMP), then simply quits without an error message. As far as I can tell, no one has actually tracked this down to a specific error condition, but it is known that installing a bunch of Windows 98 libraries will allow the install to complete.
ADDITIONAL PROBLEMS
Late 2005 versions of the Mozilla browser (Version 1.7.11) do not require the IE versions of DLLs.
NOTES
Q: Will Mozilla Firefox or Mozilla Thunderbird run on Windows 95? Are there issues involving running Mozilla products on older versions of Windows?
A: Yes, Firefox and Thunderbird will run on Windows 95, under the condition that you have appropriate system files installed. All Mozilla products (including Mozilla application suite, Firefox, and Thunderbird) since Mozilla 1.4 require version 2.30.4265 or greater of the system file OLEAUT32.DLL to run. When I ran Mozilla Firefox 0.9 on a system with the very first version of Windows 95 installed, I also had to upgrade or add other files as well such as OLE32.DLL, OLEAUT32.DLL, SHLWAPI.DLL, and URLMON.DLL. If you heed this information and apply the Windows Library Update (that contains an updated OLEAUT32.DLL) and all other applicable library updates beforehand, you should hopefully have a minimum of problems in installing and running Mozilla, Mozilla Firefox, or Mozilla Thunderbird on Windows 95 or other older Windows versions (specifically 98 original release, NT 3.51, and NT 4.0).

060110 Copied basic software to second partition 060110 downloaded Off by One Ranish Partition Manager PKZIP Firefox 1.5 Mozilla1.7.12 exe installer 060110 Firefox install A required file MSVCRT is missing -- C Run Time Library. The problem here is that Firefox assumes that the Visual C++ libraries are installed, but they do not come with Windows 95. There appear to be several (different) binaries of the version that is required 6.00.8337.0. Since we are trying to identify minimums, I went with a download from www.aggsoft.com/download/win95updates.htm. But the full Windows 98 libraries Update linked to from Q197298 might be a better bet. Note that MSVCRT needs to be installed to WINDOWS\SYSTEM, not to the default PROGRAM FILES\GHOSTS_12... Once finished.

Sees no problem with Mozilla. after unpacking \temp\ns.temp exists, but no xpcom.ns. Went thru dialog and actually appeared to install. Mozilla is installed, but now quits with no error message after splash screen. 060113 Located and downloaded 50COMUPD.EXE -- COMCTL32 update for Windows 95 -98. Now Firefox installs, but when run generates Errors "Link to export OLEAUT32.DLL.411 missing", and "A device attached to the system is not functioning" Depends agrees -- OLEAUT32 is missing stuff. 060113 Mozilla still quits with no msg after splash screen. 060113 Copied original install to third partition 060114 Copied OLEAUT32.DLL from P166. Firefox now starts. 060114 Default install includes Exchange and MSnetwork might be interesting to delete and observe affect.
