phpMyAdmin displays a Javascript error at startup (Firefox)

Question

After a change of computer, from MacOS 10.14 to 10.15, PMA displays an error at startup, and the side navigation panel is unusable (all its links and buttons have no effect). With the same configuration, Safari works perfectly. Below is the error report. All versions used (macOS, phpMyAdmin, MySQL, Firefox) are the latest versions. Which file causes this NS_ERROR_FILE_CORRUPTED error?

Resolved.

The problem came from the corrupted Firefox database. I removed /Users/[session]]/Library/Application Support/Firefox/Profiles/[random].default/webappsstore.sqlite
