I'm laughing so hard at the video, I imagine this is what browsing the web is like for the elderly that barely know how to use a computer. Can someone do this in Chrome?

This article is wonderful crazy. The icing on the cake is the discovery of a potential performance bug in one or more of the about: pages, that's definitely worthy of following up.

"I got basically all the extensions with this, making everything I did before this look really stupid." I geel this on a deep personal level.

> It turns out there’s only 84 thousand Firefox extensions. On addons.mozilla.org, but you can distribute Firefox extensions without posting on addons.mozilla.org. I do.

> I did some research to find why this took so long. 13 years ago, extensions.json used to be extensions.sqlite. Nowadays, extensions.json is serialized and rewritten in full on every write debounced to 20 ms, which works fine for 15 extensions but not 84,194. Occasionally, databases are useful. ;)

"In terms of implementation, the most interesting one is “Іron Wаllеt” (the I, a, and e are Cyrillic). Three seconds after install, it fetches the phishing page’s URL from the first record of a NocoDB spreadsheet and opens it [...] The API key had write access, so I wiped the spreadsheet."

In general concept this reminds me a bit of adding every possible installer .EXE based Internet Explorer browser toolbar to Windows 98 https://www.reddit.com/media?url=https%3A%2F%2Fi.redd.it%2Fz... https://fergido.wordpress.com/wp-content/uploads/2011/06/too...

Sad that no real pages can load successfully, but I thoroughly enjoyed the writing. > We turned on crash reporting on the way. I haven't burst out laughing like this in a while! You'll probably make for some horror stories to a poor Mozilla team.

Turns out even browser extensions can be comedy.

Is this the digital version of Supersize Me?

I love the small few who take the time to do crazy stuff like this. Very entertaining.
