Enabling copy and paste
We recently received the FireFox ESR 24 that now prevents us from being able to copy/paste within a web-based application using Ctrl+C / Ctrl+V or right-click copy/paste menus. Is there a fix for this? We have tried installing RightToClick, but this does not work either.
There's nothing in Firefox that prevents you from copying and pasting things with the context menu or keyboard shortcuts.
If you're having problems with a online editor website, make sure dom.event.clipboardevents.enabled is set to true in about:config.
RightToClick is only useful if you've encountered a website that prevents the context menu from showing, or replaces it with a custom menu that isn't useful. Even without that add-on, you can always hold down the Shift key when you right-click to show Firefox's context menu instead of the website's.
If the problems persist, first check if the issue goes away when starting Firefox with Add-ons Disabled. If that doesn't help, post an example link that's giving you trouble.
We have checked the setting referenced in your reply (dom.event.clipboardevents.enabled) to no avail. We get the following message when trying to copy/paste within this particular web-based application (Oracle's RPAS tool); however have verified the recommended setting and it still does not work. That message was: You need set signed.applets.codebase_principal_support=true in about:config.
I'm starting to think it's a compatibility issue between Oracle's copy/paste functionality and FireFox.
Use keyboard shortcuts if the buttons on the web page or other methods aren't working.
- Copy: Ctrl+C or Ctrl+Insert (Mac: Command + C)
- Paste: Ctrl+V or Shift+Insert (Mac: Command + V)
- Cut: Ctrl+X or Shift+Delete (Mac: Command + X)
Already tried short cut keys...no method works. Even created a user.js file to attempt to modify settings to no avail. Perhaps it's more of a compatibility issue with the new version of Oracle's software and not so much FireFox.
I can't say what's going on the page without a link to it, but I'd guess the site is requesting privileges that are no longer being granted. You can probably get more information if you press Ctrl+Shift+K to open the web console, click the Clear button, then attempt to perform the actions that fail to work.
Websites no longer can enable this privilege, but doing this manually by setting prefs via the user.js files should still work.
So now we are able to copy/paste if we're copying data from within the browser into the browser...but if I wanted to copy values from an excel datasheet and then paste them into the browser, this appears to still be prevented. Our application does provide a "Paste from External" option; however it is more cumbersome than simply doing a Ctrl+V. I think we may have to live with it though.
Glad to hear that it's working!

I had the same problem. Ctrl-C did not work in my Firefox because I had the add-on Translator installed, the one with the large red T. In the options box of T-translator I had a mark in the "Hotkey for the action chosen above" part in the box left of "Ctrl". I disabled that mark and after restart I was able to use Ctrl-C again within Firefox.
