LibRedirect is a great way to access a wealth of sites like youtube, twitter, reddit, wikipedia, etc. via alternative privacy friendly frontends instead of directly.
While not an inherent guarantee of privacy, nothing really is, it makes the process of rotating randomly between these frontend instances for each visit a breeze, and easy to hop to a random new instance if the current one is down/not working as expected.
But firefox containers isn't now redundant with the isolation of cookies? I know that it has other uses but that was the main use for a lot of people before Mozilla push that update into the browser.
I used to use containers but yeah Firefox's total cookie isolation which is now on by default does a similar job and it's basically idiot proof, whereas containers required a fair bit of setup and ongoing adjustments.
Ublock Origin - hands down by far the best extension ever
LocalCDNs - substituting previous DecentralEyes
Cookie AutoDelete
ClearURLs
CanvasBlocker
Temporary Containers - leverages firefox containers in an automated way (if you enable it),in my setup, to open every page in a new domain into a separate container
Used to use:
. PrivacyBadger - redundant with ublock on expert mode and 3rd party requests blocked
. DecentralEyes - same as LocalCDNs but supposely with less content to substitute
. HTTPS Everywhere - redundant with new settings in firefox
. NoSricpt - with uBlock in expert block and blocking javascript by default i have all the granularity i need
. uMatrix - same as above
also, use the best (for privacy/digital hygiene) firefox forks: Librewolf on desktop, Mull on android
I would suggest to add here the DuckDuckGo Privacy Essentials extension, just for the automatic private duck email addresses when filling in web forms, since the 3rd party tracking blocking feature is a bit redundant in conjunction with uBlock Origin etc.
private emails/aliases are a very good measure indeed. but for that i use a separate service, with SimpleLogin - needs sign up, but for Android the client app is also available on F-Droid
Privacy Badger, uBlock origin, LocalCDN. Containers are pretty good for Firefox too, keeps things segregated to stop cross-site tracking. Also I auto-clear cookies and cache on exit and just whitelist what I want to keep.
Use Tor Browser if you need anonymity, which isn't offered by private browsing mode or most other extensions. In case you don't want to route through the Tor network, Mullvad Browser offers the same fingerprinting resistance techniques as Tor Browser.
