Last version for a Pentium III processor

I have a very old Thinkpad 600x that has a Pentium III (coppermine) processor. The current system requirements for the latest versions of Firefox reference a Pentium 4.

I'm currently running 3.5.13. None of the current add ons work with this version. What is the last version of Firefox that will work with a PIII? Operating system is XP, SP3. I want to install some form of Ad Block, and none are compatible with 3.5.13.

Re: Last version for a Pentium III processor

hello, have you tried it with the latest version from getfirefox.com (firefox 19) - the requirements state "recommended hardware" (so this might leave a little bit of leeway)?

Re: Last version for a Pentium III processor

This is a 450 mhz processor. Computer was built in 2000 and still works like a charm. But so much today requires newer, faster hardware. The HD on this thing is only 25G, but it originally came with a 10G HD.

I should think that there might be vast numbers of people out there with functional, but outdated, hardware who still need to access the web and be safe and secure. It kind of upsets me that Mozilla would not continue to support the browsers that work for people in that situation.
