Strangely, some programs appear to have internet connection and function as intended, others just don’t? For example: Firefox seems to be absolutely fine, but Librewolf searches time out? Some terminal commands requiring internet work, others seem not to? Not sure whats happening but would appreciate some advice (:
Is this a new install? Or is this on an existing install which used to work before?
What DE are you using?
Have you tried pinging to the IP addresses that don’t seem to work?
Are you using a VPN?
Have a custom firewall setup?
It sounds like deliberate experiements to DNS using random guides found on the internet.
Check the firefox settings → privacy → scroll to the bottom → the default is to use firefox dns - which explains why firefox works but librewolf do not.
Then again - DNS can cache lookups which make cached responses work but new requests will fail.
