Such a shame really good software sources followed laceware maker MS when it pulled the plug on perfectly adequate Win98 SE. Not everyone can afford (I'm 72 and a LOW income pensioner) Mb hungry products with unnecessarily flashy bells and whistles.
Sorry, Mozilla doesn't have the manpower to continue supporting older operating systems. Mozilla still supports Win2000, which is older than SE & ME, but that OS is the base of WinXP & Vista. The Win95, 98, SE, ME OS line was buried when ME went EOL.
Firefox 220.127.116.11 works fine, but is lacking hundreds of security fixes that were done for later versions of Firefox. I still use 18.104.22.168 for few hours each day and have no problems with it on WinXP, but Anti-Virus applications are still readily available for WinXP, where your selection of AV programs is quite limited for Win 98SE.
Great job by all involved with Firefox/Thunderbird/Sunbird etc. It's understandable that you are unable to continue support for Win98, especially as the user base has all but vanished. There are various reasons one may choose to continue to use Win98. Perhaps they have a machine that is still functional for
browsing the web and other assorted things but will not support WinXP. For some reason my Compaq PIII won't load XP. Not to worry brothers and sisters, try a Linux distro, like Lubuntu or PClinuxOS LXDE. There is a bit of a
learning curve, but they are FREE. Yes, its true, a free OS, and they have versions for older, less powerful machines. They aren't perfect, but, then again nether is the big W. Not all distros will work on all machines. You may have to try a few to see which works best on your hardware, but all of
them I have tried have repositories that have gobs of FREE software for
office stuff (writing documents and such), playing music, viewing pictures,
printing, and your favorite e-mail and browser that you are already familiar with, that would be Firefox and Thunderbird. They, the Linux folks, have other browsers and e-mail clients that you can use, but when you are comfortable with one you may not want to change. Oh yeah, most all to the
Linux distros have what is known as a LiveCD. This means you can boot from the CD and try the OS without having to install to your hard drive. Further, if your trial works to your satisfaction, you can, usually, install a Linux distro and keep your beloved Win98. This little bit of magic can be done several ways, but it is mostly a gift from the GRUB works. Check these
If all of this seems a bit complicated, try to find someone locally who is conversant in Linux and or BSD. You may be able to find someone at a repair shop.
Best regards to all
