It's gotten a lot more annoying the last several years with 5mb webpages. Backing up the whitelist saves a lot of time.
For perspective, I use 4 separate profiles (--user-data-dir) listed in descending order of how annoying they are for me to use.
1). School browser: Chrome + uBlock origin
2). Shopping/low security (when the payment processor is an iFrame and I don't want to refresh...): Firefox + uBlock origin + CanvasBlocker
3). General browsing like browsing Google or YouTube: Chrome + uBlock Origin + uMatrix
4). VPN browser: Chrome + uBlock origin + uMatrix + CookieAutoDelete + VPN extension
I've gone from 2 browsers (Firefox + IE6) to 4 browsers (Firefox, Chrome1, Chrome2, Chrome3). By 2030 I'll be running 16 browsers in a virtual machine on a remote server that I connect to with my browser browser.

No updates is not necessarily a bad thing. Sometimes things work well enough to leave alone.
