Firefox is really slow compare to chrome

Hi,

The web UI is really slow in Firefox compare to Chrome. This is on 7.1.5 pro seafile on standalone server. Standalone server is Centos 8 with 4 GB of memory (nginx proxy with let’s encrypt SSL, Mariadb 10.15.4-1 and memcached). The Firefox version is 78.0.2 (64 bit) while Chrome is 83.0.4103.116 (64bit). It is really snappy in Chrome. The wait in Firefox is like 30 to 45 seconds. The android seadroid is pretty snappy too.

Any ideas with this slow Firefox performance? Thank you.

Jacky
