Add-on Armageddon
Installing Every* Firefox Extension
84k add-ons, one browser meltdown: cheers, nitpicks, and calls for a Chrome sequel
TLDR: A developer installed almost every Firefox add-on (~84k) from the official store and may have uncovered a performance bug. Commenters cheered the chaos, demanded a Chrome sequel, and argued that off-store add-ons mean it wasn’t literally “every” extension—showing stress tests can spark real fixes and big laughs.
A developer tried the most chaotic science experiment on the internet: install basically every Firefox add-on from the public store — around 84 thousand — and see what happens. The result? A hilarious browser meltdown reel that had commenters doubled over. One fan said they “can’t stop laughing,” and the top request was instant: do it again, but in Chrome. The vibe: equal parts applause and popcorn.
But the crowd wasn’t just giggles. The brainy corner spotted something serious: a potential performance bug lurking in Firefox’s internal “about:” pages, the kind of thing you only find when you unleash 84k gremlins at once. Meanwhile, the nitpick brigade pulled receipts: it’s not literally every extension because you can ship outside the official store, thank you very much. Still, the stunt was wild — using Mozilla’s public API to scrape the catalog, remixing sorts, and even a cheeky trick to peek past page limits — ending at an eyebrow-raising 99.94% installed. The author’s self-roast (“made everything before look really stupid”) became a mood, with readers relating to the chaotic triumph. Bottom line: the internet is obsessed, the engineers have a bug to chase, and the sequel demands are getting louder.
Key Points
- •The author targeted roughly 84,000 Firefox extensions on addons.mozilla.org for installation.
- •Using the Add-ons API search endpoint initially revealed only 600 pages (~30,000 extensions) with default sorting.
- •Combining multiple sorts (created, rating, hotness, updated) increased unique counts to 67,945 but with diminishing returns.
- •The exclude_addons parameter allowed fetching results beyond the 600-page limit, limited by URL length to ~20 extra pages.
- •Overall coverage reached about 99.94%, with a small number of extensions missing due to scraping gaps or deletions.
