Where are my add-ons in Firefox 42??
Since I updated to Firefox 42 in my Mac, I can't find my add-ons, just a bunch of ads for more add-ons.

Do you still see any extensions in the extensions folder in the Firefox profile folder?
You can use this button to go to the current Firefox profile folder:
- Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
- http://kb.mozillazine.org/Profile_folder_-_Firefox
Do you have an "Old Firefox Data" folder on the desktop in case you have refreshed Firefox and created a new profile?
You can recover data from such a saved profile, but be cautious to recover possibly corrupted files.
It is possible that there is a problem with the file(s) that store the extensions registry.
Delete the extensions.* files (e.g. extensions.json, extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry.
New files will be created when required.
See "Corrupt extension files":

If you see disabled or not compatible extensions in "Firefox menu button/Tools > Add-ons > Extensions" then click the Tools button at the left end of the Search bar to check if there is a compatibility update available.
If this hasn't helped then also delete the addons.json file.
