So, you can uninstall the extensions, double-check the proxy connection and disable and re-enable the add-ons. You can transfer the data from your old profile to your new one if you fear that your data will be lost. 

Solution 3: Identical Information on Self-signed Certificates

Firefox can have trouble processing the certificates of SSL if you are accessing an internal website or a developer. Firefox can get choked by the possible paths when the new certificate contains similar information and it has been replaced numerous times. You can notice that when you have stored about 9 to 10 self-signed certificates, Firefox will slow down. 

So, you can resolve this problem by performing TLS Handshake Firefox with the help of the following steps:-

  • Open Firefox and in the address bar, you have to write “about: support”. 
  • Go to the field of “Profile Folder” and click on the “Open Folder” button. 
  • Now, locate the “cert8.db” file. Then, you have to rename this file. This will help Firefox to replace the file when it restarts. 
  • Next, open Firefox and go to the site that was affected previously.
