# Firefox
|
||
|
|
|
||
|
|
Make using the web more safe by disabling commonly used techniques and mechanism _without_ sacrificing usability.
|
||
|
|
|
||
|
|
Why Firefox? It provides high configurability, is open source and thus better to be reviewed by external security advisories.

2. Fix white bar on YouTube when using uBlock Origin (_if applicable_). Add the following as a line in My Filters of the extension:

How to do it?
|
||
|
|
|
||
|
|
* Use the provided `user.js` file and copy it into your Firefox profile folder while application is _not_ running.
|
||
|
|
|
||
|
|
To find your profile folder, click on the menu top right, on `Help -> Troubleshooting Information`. You can directly open your **Profile Directory** from there or see it, typically it's something like `$HOME/.mozilla/firefox/...` or in Windows `%APPDATA%\Mozilla\Firefox\Profiles\...`
|
||
|
|
|
||
|
|
* Adjust values by browsing `about:config` in the address bar. `""` means empty, just delete the characters and press ENTER.
|
||
|
|
* Create your own profile and copy it into the application data folder while application is _not_ running. See [https://ffprofile.com](https://ffprofile.com).
|
||
|
|
|
||
|
|
Some settings _might_ break website behavior although this is not very likely. Be aware of that!
|
||
|
|
|
||
|
|
Use an external password manager like KeepassXC, at least AutoFill is advised to be disabled). See [https://www.privacy-handbuch.de/handbuch_21j2.htm#08_07_18](https://www.privacy-handbuch.de/handbuch_21j2.htm#08_07_18).

|
### Common User Preferences
|
||
|
|
Optional, but commonly used to ease browsing. Not security-related.
|
||
|
|
|
||
|
|
```
|
||
|
|
general.smoothScroll = false
|
||
|
|
general.smoothScroll.pages = false
|
||
|
|
mousewheel.min_line_scroll_amount = 40
|
||
|
|
browser.newtabpage.activity-stream.feeds.topsites = true
|
||
|
|
```
|
||
|
|
|
||
|
|
Optional and **potentially dangerous in terms of website behavior**, for _GNU/Linux only_.
|
||
|
|
|
||
|
|
```
|
||
|
|
image.mem.max_decoded_image_kb = 512000
|
||
|
|
media.getusermedia.aec_enabled = false
|
||
|
|
media.getusermedia.agc_enabled = false
|
||
|
|
media.getusermedia.noise_enabled = false
|
||
|
|
```
|
||
|
|
|
||
|
|
## Additional hints
|
||
|
|
|
||
|
|
Besides securing Firefox, you should consider not using the DNS servers of your Internet provider and instead install system-wide [DNS alternatives](https://www.kuketz-blog.de/empfehlungsecke/#dns) or a [local DNS server](https://wiki.archlinux.org/index.php/Unbound) which directly queries root DNS servers. There's really no downside of this.
