On any website I go to, when I highlight and try to copy text from the body of the page with my mouse, nothing happens.
I'm trying to copy by highlighting text and and right clicking with my mouse. As far as text, for example, if I try to copy the text in your message, I can't.
Also ,I play evony and they use flash to display messages and copy don't work with that. I use a image capture for that.
Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
Is this a recent problem...after the last update on Oct. 27, 2010? Were you able to copy and paste before the 27th? My optical marble mouse has had a breakdown from the update. No longer can I do a smooth scroll in Mozilla. However, I can in I.E. and Outlook Express. I posted on the 28th.
