Hello,

I'm not sure I understand your question correctly, but if you don't want to see advertisements, you could consider an ad blocker, like :

uBlock Origin https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/

Or AdBlock Plus https://addons.mozilla.org/en-US/firefox/addon/adblock-plus/

'Hope this is what you are looking for ......

Firefox from Mazolla.org does not have any ads. But you may have picked up something.

You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.
