Strip tracking tokens from URL query strings
The Tracking Token Stripper add-on will remove tracking tokens from web sites such as Google Analytics, Google and Facebook. You can create your own custom rules with uBlock Origin, to remove for example marketing_token: https://github.com/gorhill/uBlock/wiki/Static-filter-syntax#removeparam
From documentation:
removeparam must be assigned a value, which value will determine which exact parameter from a query string will be removed:
*$removeparam=utm_source
The above filter tells uBO to remove the query parameter utm_source when present in a URL. The value assigned to removeparam can be a literal regular expression, in which case uBO will remove query parameters matching the regular expression:
*$removeparam=/^utm_/
Show special characters in domain names in address bar
To improve security and better be able to spot fake domain names with special characters in them, enable showing of special characters in the Firefox address bar: Open about:config and set the network.IDN_show_punycode to True.
Now, if you enter https://сіѕсо.tld/ it will be shown as https://xn--n1afa3fe.tld/ and not https://сіѕсо.tld/ helping you spot the difference.

Make text bigger per web site
Firefox can remember the zoom level (press Ctrl and + or -) for each website: Open about:config and set the browser.zoom.siteSpecific to True.
Set zoom increments by adjusting toolkit.zoomManager.zoom, for example adding more steps:
.3, .5, .67, .8, .9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.65, 1.7, 1.75, 1.8, 2, 2.4, 3, 4, 5
Test by opening a Private Window with Shift+Ctrl+P.
