Hello recently I uninstalled adblock plus on my mac PPC which I use for browsing with Firefox version 3.6.28.

I also, tried installing other addons that are still capable of running on my old system.

Every time I do the following error occurs:

Firefox could not install the file at

https://addons.mozilla.org/firefox/downloads/file/140737/adblock_plus-2.0.3-sm+tb+fn+fx.xpi?src=version-history

because: Signing could not be verified. -260


Please help

Thank you.

hello, on such an old hardware please try to use the firefox build by the tenfourproject instead: http://www.floodgap.com/software/tenfourfox/ since firefox 3.6.28 has been unsupported for years, mozilla and addon authors won't pay much compatibility consideration to it if any...
