Do you have the .1 update to 54.0.1? You can check using the Troubleshooting Information page. Either:

• "3-bar" menu button > "?" button > Troubleshooting Information
• (menu bar) Help > Troubleshooting Information
• type or paste about:support in the address bar and press Enter

In the first table on the page, you should find the full version number.

SearchAssist Incognito

Run most or all of the listed malware scanners.
They all work differently   -   what one program doesn't pick up, the others might.
