# 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.
|
|
|
|
Based on [https://www.privacy-handbuch.de/handbuch_21.htm](https://www.privacy-handbuch.de/handbuch_21.htm).
|
|
|
|
## Recommended extensions
|
|
|
|
|
|
```
|
|
uBlock Origin (ads)
|
|
|
|
HTTPZ or HTTPS Everywhere (automatically redirect to the Secure version of a website)
|
|
|
|
Neat url // removes common parameters from pages (e.g. to identify you with something like ?os=windows&....)
|
|
|
|
Skip Redirect // skips not needed redirects of pages
|
|
|
|
CanvasBlocker // for some JavaScript (web) API
|
|
|
|
Cookie AutoDelete // automatically delete cookies
|
|
|
|
(an extension for a passwordmanager like KeePassXC if needed)
|
|
|
|
(Use Invidious instances for a liberated YouTube experience)
|
|
|
|
(Greasemonkey to get rid of some annoying popups, see below)
|
|
```
|
|
|
|
All extensions, especially extensions interferring in redirects like `Skip Redirect` _might_ lead to malfunctioning of some websites. Disable it per page.
|
|
|
|
You can **hide extension icons** in the overflow menu if you like. Just right click the icon in the top right in the menu bar and "pin to overflow".
|
|
|
|
### uBlock settings
|
|
|
|
For the uBlock plugin import the `ublock-config-1.txt` in the "My Filter" menu for proper settings.
|
|
|
|
### Remove Google and YouTube popups
|
|
|
|
Recently, Google added popups on YT and search so you need to login. In the Greasemonkey extension, import the `greasemonkey.zip` in this git repository and they should be gone.
|
|
|
|
## Recommended search engines
|
|
|
|
If not possible in another way, you can add them via [Add custom search engine](https://addons.mozilla.org/en-US/firefox/addon/add-custom-search-engine/). Just follow instructions after installing and opening 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.
