Is Fennec nonfunctional for anyone else?

I woke up one day and Fennec wouldn't browse any web page. Like, if I do a search, which goes to DuckDuckGo, I get a loading bar that never goes anywhere. (See screenshot).

If I disable all of my extensions, it'll work again. Then, if I enable them one by one to try to find the culprit that was making Fennec not work, it doesn't break! Until it does, randomly. I basically can't easily reproduce it working or not working.

I switched to IronFox, and installed all the same extensions, and have had no problems for two days.

Extensions:

• JShelter
• UBlock Origin
• Decentraleyes
• Cookie AutoDelete
• Absolute Enable Right Click & Copy
