By not using Firefox, you remove the funds from the WebKit development. And it costs millions. If LibreWolf doesn't present itself as Firefox, it also decreases the visible Firefox usage, helping the duopoly.
I used Firefox until they lost site of their core target, and killed their mobile app's quality and extensions.
It doesn't on my phone.
Last I checked, Mozilla did everything in their power to prevent you from running desktop extensions.
If I may ask:
1. Which version are you using?
2. Where did you get that version?
3. What settings/process did you change/follow to make firefox accept all desktop extensions?
Please be as specific as you can. A link to a Mozilla resources. if you can provide it, would be even better.
