I received a Mozilla Firefox Seems Slow error message when I opened the browser, and instead of clicking on Show Me What To Do, I accidentally clicked on Don't Show Again. How can I undo this (meaning, if I were to get the error next time, I want to be able to click on Show Me What To Do)? Thank you

If you are referring to the "Firefox seems slow… to… start" message, try this:

  1. Open about:config in your address bar, press Enter and accept the risk.
  2. In the Search field, type browser.slowStartup.notificationDisabled or a part of it.
  3. Look at the value of the preference - it’s likely set to true. Highlight the entry, right-click and select Toggle or Reset to set it to false.

The warning should be displayed again next time the browser starts to slow down under similar circumstances.

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

If you use Adblock Plus then you can consider uBlock Origin as a replacement to see if that works better (lower memory footprint).
