Last year my laptop was running a little slower than I wanted, so I backed up everything onto an external hard drive, uninstalled & removed all my software, and wiped my computer. Started over, fresh.
It was a lot of work, but that made things so much better. I reinstalled the operating system, put most of my files and software back onto my computer, and I was ready to move on.
I opened my internet browser and realized I had never backed up my bookmarks!! Who would remember to do that? I hope you would, but for whatever reason, I didn't even think about it, even though I tediously went through the entire contents of my laptop to make sure I had everything else, including old emails.
I had a few years worth of bookmarks saved, before I wiped my computer. I frantically logged into my Firefox account, and then Chrome... but they weren't there. I hadn't turned on the native backup so they'd be stored in my account. CRAP.
Months later, after building up important bookmarks again (and this time they are backed up) that major loss of info from before led me to also put my bookmarks in a new location. One that I can access anywhere, any time, from any device.
That's why I chose to use Trello to save my browser bookmarks.
