Can't open URLs (have checked add-ons), troubleshooting doesn't work
Links in emails simply don't work anymore. Click on it, nothing happens. I tried restarting in safe mode with add-ons disabled; I also found some instructions for going into Troubleshooting and looking for anything called network.protocol-handler.external-default -- this did not exist in the Troubleshooting in my Thunderbird. Actually, there was nothing with "protocol" in it at all. I believe this started happening with the most recent Firefox update. This is likely why "Help Contents" and "Release Information" no longer do anything.
Additionally, there's no way to customize the search engine. I have my choice of Bing, Yahoo, Wikipedia, Twitter, AOL Web Search and Amazon.

The handlers are in the config editor, troubleshooting does not give you any chance to edit the few modified setting it lists.
Basically I suggest you reinstall your browser. almost all of the complaints in these forums about browsers have nothing to do with Thunderbird and everything to do with the operating system and the browser of choice.
I just reinstalled Firefox 57.0.4 a couple of days ago. I can do it again, but will have to go to the Firefox support desk if it doesn't help. (Also I should have said this before but I'm using Windows 10.) Thank you.
You have to set up Firefox as the default browser. Do this via computer Control Panel.
Just in case your computer is not acknowledging that the updated Firefox is the same as previous Firefox.....
Exit Firefox Exit Thunderbird
Suggest unchecking - or choosing another browser temporarilly eg: chrome Then resetting everything as default again.
The problem is rarely Thunderbird and most often lies with your computer not knowing what to do when it is asked to open a link. Perhaps it does not recognise the new Firefox is the same as the old Firefox.
