Hello,

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:

1. Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
2. Under "Time range to clear", select "Everything".
3. Now, click the arrow next to Details to toggle the Details list active.
4. From the details list, check Cache and Cookies and uncheck everything else.
5. Now click the Clear now button.

Further information can be found in the Clear your cache, history and other personal information in Firefox article.

Did this fix your problems? Please report back to us!

Thank you.

Please clear your History and also cookies. sometimes addons may also create problems.check out which addon effects you. Thank you.

I cleared cache few times, still same. One of my friend said he has same problem with Firefox.

I get the same issue on Twitter using FF v24 in Safe Mode.

I think the issue is on Twitter's side not Firefox's.

I suggest reporting the issue to Twitter's Support team here:
