tried installing ublock, oldest version, got an error message: could not install the file at https://addons.cdn.mozilla.net/user-media/addons/576580/block-0.
All attempts to install any add-ons from the Mozilla add-on page resulted in the same message: Firefox could not install the file at
because: Signing could not be verified. -260 What's this signing thing and why can't I download any add-ons???

You've got (out-of-the-Ark) Fx 3.6.28; I've got Firefox 44.0.2. I think this will explain nearly all of your problems. Someone else will give you the best advice on how to start again with Firefox for your Mac.
Hello hattiejean, alan_r

Confirm, alan_r is correct, the problem is definitely the 3.6.28 firefox, but hattiejean you can't install latest firefox, the one you use is the latest for your 10.4 Mac.
thank you
You can use the third-party TenFourFox to be much more up to date and secure. http://www.floodgap.com/software/tenfourfox/
It is based on the Firefox 38.6.1 ESR release.
The OP has an Intel Mac according to the user agent, so using TenFourFox isn't possible.

I don't know if you can update your Mac to OS X 10.6 to be able to install the current release.
