Firefox hangs whenever I open a new tab
Recently whenever I open a new tab Firefox hangs / freezes for a second. It never did this until just this day, the only thing I can think is if updating my Bitdefender client did it, but I turned off every portion of it related to browsing safety and still get the hangup issue.
I've already down a firefox refresh as a bunch of other things tell you to do, I did go through the trouble of making a Gecko report and I'll link it though.

You can check for problems with the places.sqlite database (bookmarks and history) in the Firefox profile folder.
- use "Verify Integrity" on the "Help -> Troubleshooting Information" (about:support) page
in case errors are reported close and restart Firefox and retry
If "Verify Integrity" on the "Help -> Troubleshooting Information" (about:support) page cannot repair places.sqlite then remove all places.sqlite files in the Firefox profile folder. Firefox will rebuild places.sqlite and restore the bookmarks from a recent JSON backup in the bookmarkbackups folder.
- keep a backup copy of places.sqlite in case a new places.sqlite database has to be created

You can check for problems with the sessionstore.jsonlz4 file in the Firefox profile folder that stores session data.
- delete sessionstore.jsonlz4 and sessionstore.js
When sessionstore.jsonlz4 is deleted you lose pinned tabs and open tabs and you will have to recreate them, so if necessary make a note or bookmark them.
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
