FAQs

Should I use Incognito for everything?

No. Incognito only hides local history – websites/ISPs still track you. Use proper privacy settings instead.

Are browser extensions safe?

Many aren’t. Install from trusted sources only. Check reviews, permissions, and update regularly.

Fastest browser for low-end PCs?

Brave or Firefox (tuned) offer best speed/security balance on older hardware.
