I tbh would say, just go with Kubuntu. You can always switch afterwards when you end up not liking it, especially the fact that family members use it can be helpful.

Backups, always do backups of your important stuff, this is not a thing exclusive to Linux, but something many people forget about.

@[email protected] Do you still require help?

Just go through the settings and you will probably be able to judge urself what to change.

You can also choose to install an Content Blocker, like uBlock Origin + other extensions which might be beneficial depending on ur threat model.

You can optionally check out following:

• ClearURLs (probably unecessary if use uBO with appropriate filters + ETP, but you can still used it in addition)
• CanvasBlocker (slightly advanced), JShelter (advanced)
• LocalCDN (fork of decentralised eyes)
• Auto Referer
• LibRedirect
• NoScript

SimpleLogin, Addy.io, Adguard Tempmail

You’re welcome :)
