Why is Trello very slow and resource-hungry after updating to Firefox Quantum?

Since the update to Firefox 57, boards in Trello have been unbearably slow - actions such as clicking and dragging a card to move it to another list or opening a card take tens of seconds, and my laptop fan spins up immediately upon opening the board.

Other websites work fine in Quantum, so it seems to be something specific to Trello or a technology that Trello uses.

Trello works fine in other browsers, e.g. the latest version of Opera. The Android Trello app on my phone is also working fine.

Maybe it's using some sort of unsupported scripts

You can try these steps in case of issues with web pages:

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

  • hold down the Shift key and left-click the Reload button
  • press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
  • press "Command + Shift + R" (Mac)

Clear the cache and remove the cookies from websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Clear the cache:

  • Options/Preferences -> Privacy & Security -> Cached Web Content: "Clear Now"

"Remove the cookies" from websites that cause problems.

  • Options/Preferences -> Privacy & Security -> "Use custom settings for history" -> Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
