hidden saboteur: why a dark mode extension keeps wrecking my online store's checkout

Any red console errors pointing at a chrome-extension:// or moz-extension:// address?? ?

sorry forgot to say interesting detail: teh Network tab shows a script named like an analytics file being blocked on my online stroes checkout.

😭

WOWWW finally got it working, thanks everyone cant believe it was that simple lol

If youre teh site owner: wrap third-party and optinoal scripts so a failure doesnt stop your main code, avoid relying on globals an extension might overwrite, and add a small note in your help pages suggesting customers disable a password manager extension for the site if they see problems. worked for me anyway 🤷

ok so try turning off the BIOS first, fixed it for me. told my boss it would take 10 minutes. its been half teh night

Firefox has Troubleshoot Mode (Help > Troubleshoot Mode) which starts with all add-ons disabled. Chromium browsers can be started with a fresh profile instead. If teh site works there, uve proven its local, not teh website. lmk how it goes

lol same thing happened to me make a backup before u touch teh extension, learned that the hard way

been there man dark mode and grammar extensions modify teh DOM and inject styles into every page. editors, canvases and custom inputs often break because the extension rewrites colors or wraps text nodes. most of these extensions let u disable them per site; thats usually better than uninstalling.

ad blockers match on file and element names 🤦 scripts called something like ads.js, tracking.js or analytics-bundle.js get blocked even if theyre essential, and checkout or video players die. check the Network tab for requests marked blocked by client; if u own the site, rename essential files and dont make core features depend on tracking scripts.

open DevTools > Console and look for errors whose source starts with chrome-extension:// or moz-extension://... that ID matches one of your installed extensions, and you can see it on teh extensions page with Developer mode turned on.

Disabling per site is fine, but some of these extensions update constantly. Id report teh issue to the extension developers too, otherwise itll happen again on teh next site.
