Can not copy-paste tweets on Twitter
It is a weird problem. I am unable to copy from or paste into a tweet in Firefox. e.g.
- I can copy some content from a web-page but can not paste it into tweets at Twitter (works in Chrome) - If I copy some content from a tweet, then it does not appear when I paste it, just empty (works in Chrome)
I can do all of copy-paste without any problem in other web-pages in Firefox (gmail or forums registrations e.g.). I have cleared all the cache, even deleted ~/.mozilla and ~/.cache directories by hand too but nothing helps.
