Using firefox but concerned now

Read about some alternatives:

• ARC not OSS and VC funded, NO.
• Waterfox, FOSS
• Librewolf, FOSS
• Zen, FOSS but is just a skin??
• Ladybird, FOSS
• Orion?
• Arctic Fox
• Mullvad

Edit 2/28: It seems there is no general consensus if we should switch and/or to what.
