1Password Chrome extension is incorrectly manipulating <code> blocks
The latest 1Password Chrome extension is incorrectly manipulating the DOM within <code> blocks on static pages. It looks it's using prism.js to try to add syntax highlighting to <code> blocks on the ...

Hey everyone! I want to thank everyone who called our attention to this and explain what happened and what we’re doing about it.
What happened: Prism.js is a syntax-highlighting library we use for our Labs Snippets feature. While optimizing our build to reduce bundle size, we unintentionally bundled Prism.js into the extension in a way that caused it to run on pages where it shouldn’t, which interfered with code formatting on certain sites. We apologize for the inconvenience this caused.What we’re doing about it: We’ve completed the fix and submitted it to the Chrome Web Store, along with Firefox, Edge, and our other supported extension storefronts. Rollout timing depends on each store’s review process, but we expect it to land over the next few days.
We want to emphasize that vault security was not impacted. At 1Password, protecting our customers’ privacy, passwords, and credentials is our highest priority.
We’ll be publishing a postmortem covering what went wrong, the timeline, and the concrete changes we’re making to how we build and release future browser extension updates.

Seeing this also in a number of other sites (including my own). One example (not my own):
https://mac.install.guide/terminal/path
EDIT: Am also seeing the same occur with the 1Password extension in Safari on both macOS and iOS. Doesn't seem to affect Firefox (macOS, at least), interestingly.
EDIT #2: The lack of the problem is Firefox is likely because of differing versions in the extensions themselves. While I have each browser's 1Password extension set to allow automatic updates, the one for Firefox is at only v.8.11.16.35 (October 28, 2025), while the one for Chrome is at v.8.11.22.27 (December 15, 2025); these versions appear to be the latest available for each browser. As for the Safari extension, it would seem to be v.8.11.22 from approximately one week ago (Apple's App Store shows only relative dates, such as "1w ago").
