No matter how much the orange man pretends to distance himself from it, one detail will always be true: Democrats and liberals will never support Project 25. So the only way Project 25 has any viability is with a conservative in the White House.
So, Comb-over Donnie, tell me again how you have nothing to do with it? It won’t happen without you!
Do you have any Amazon add-ons (extensions) installed in Firefox? Did you, or someone who uses your computer, install any software recently?
If it is a Firefox add-on causing the issue and you have more than one that could be the culprit, start by disabling all of them. If that fixes the issue, then it is just a matter of enabling each add-on (one at a time) to discover which one is causing the issue. When you figure out which one it is, uninstall it.
