WhatsApp Web does not work with
Firefox 47.0.1 on Windows 7 64-bit OS. I have tried making it work after disabling the add-ons and restarting Firefox in safe mode, yet this did not resolve the issue either. I am not even presented the QR code as you can see in the following screenshot this is what I get when I go to WhatsApp Web. However, on my office desktop PC which also runs the same Windows OS and the same Firefox version, this page loads correctly. What might be the problem?
Solved here. type about:config in the address bar. Locate the option dom.storage.enabled and set it to True
Okay I got the problem resolved without messing with add-ons, plug-ins, history, bookmarks and sync features by just displaying
Troubleshooting Information from the menu to the right of the Firefox. Then I opened the profile folder from there and deleted the
prefs.js file to have it refreshed. When I launched the browser again all my settings were gone, but I was able to log into WhatsApp Web.
I'm using Waterfox 184.108.40.206 (64-bit) and all of the sudden, one morning, I started to receive the message below when I tried to access web.whatsapp.com:
WhatsApp works with Mozilla Firefox 30+ To use WhatsApp, update Firefox or use Google Chrome, Safari, Microsoft Edge or Opera.
privacy.resistFingerprinting was false. I change it to true and now I can access web.whatsapp.com, after pressing LEFT CTRL+F5.
I use Waterfox, a fork of FIrefox. Current version is 56.2.10. I followed
Anderson_'s answer, Just pressing
CTRL + F5 (regardless of which
CTRL key) works for me every time I do it,
According to this site¹,
CTRL + F5 makes a browser reload the page from network rather than from cache.
If Waterfox simply goes to WhatsApp Web or a "normal" reload command is issued,
Whatsapp works with Mozilla FIrefix 30+ page pops back up. It also obviously happpens when Waterfox just launches and loads WhatsApp Web. In general, browsers load/reload pages from cache, so forcing a network reload with
CTRL + F5 seems to reliably bypasse cache, therefore, bypassing the issue.
For me, switching
privacy.resistFingerprinting back to
about:config solved the issue.
Try go Help>Troubleshooting information and click on the safe mode restart firefox without add-on. After login whatsapp on safe mode just restart your firefox back with add-on and it should be logged in.
