Well, this is a fascinating murder mystery that establishes 3 compelling suspects - Grammarly, Chrome, and a gif - and then just ... ends, right before the big reveal.

I have a friend who worked at Gusto, and my wife tried using Gusto for her small business (they handle payroll for small business, got a big boost from the pandemic). The lack of technical resolution here is so Gusto, it hurts.

I mean, this story is a hell of a rundown of debugging. The fact they don't have insight into the ways Chrome or Grammarly work isn't something to apologize for.

The weirdest one I saw was this: User claims that the wording of the info they enter into a certain form changes when they save. At first I suspected someone else editing the same form at the same time unbeknownst to each other but it wasn't the case according to the logs. And I saw the correct wording on my own computer.

Then I noticed in their screenshots that some of the menus had weird wording too. Turns out they had Chrome's "Translate this page" option on. Problem went away when we showed them how to properly switch languages in the app.

Did they open a bug against Chrome with the image file? I feel like any crash on user-provided data is a big deal, always a correctness problem, but potentially a security problem. "We deleted the image so the problem is fixed for us" is OK (I wouldn't waste time writing a blog post about it personally), but I think that Chrome needs to fix this bug.

Reminds me of the story I read where the guy's car wouldn't start depending on what flavor of ice cream he picked and when investigated he was right. Some kind of evaporation/vacuum leak or something that was dependent on time and some flavors were farther away in the store and took more time to buy.

Was it actually a Chrome bug though? It only happened when the Grammerly desktop app was installed. My guess is grammerly is doing something sketchy.

What an interesting conflux of tech to create this bug. That's the web in 2023. I would love to know if it was a Chromium bug that got resolved, but navigating this is tough: https://bugs.chromium.org/p/chromium/issues/list?can=1&q=gif... Also, I am fully here for Gusto posting this to say "wasn't our fault" and to throw some shade at Grammarly in the process

Seems like they're posting it because it was a fun story, and it's free advertising - this wasn't externally visible so I don't see where fault comes into it.

Such a tease. At least upload the gif so people can poke at it!

Agreed! I have absolutely no idea how a combination of grammarly and a specific gif would cause a browser crash though… Anyone here use the grammarly desktop app? Any additional clues?

I‘d guess it’s because Grammarly enables full accessibility support in Chrome to be able to access the browser elements similar to e.g. a screen reader. This is off by default and has caused me various issues in the past when enabled (e.g. https://bugs.chromium.org/p/chromium/issues/detail?id=136448... ). However it’s probably good that the Accessibility functions get more exposure due to this.

Maybe adding Grammarly created enough of a lag causing the GIF file to be shown?
