MercadoLivre error message when clicking button.

[coltson]

Hi. When I click the "comprar agora" button on any MercadoLivre webpage, a blank page with the following message shows up

Code: Select all

Please try troubleshooting in the latest version (34.1.0). Your Pale Moon at 33.2.0 is almost two years old at this point

[moonbat]

Also get rid of Palefill, since Pale Moon now supports whatever compatibility fixes it was compensating for before and it is now redundant.

[coltson]

Latest Palemoon doesn't work on my system

[adoxa]

You want the SSE2 build.

You want the SSE2 build.

It doesn't work either.
