Hi, There are many programs and websites you can not use the mouse for. Have you tried using keyboard commands ?

Copy = CTRL+C Paste = CTRL+P https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly

Please let us know if this solved your issue or if need further assistance.

Have you tried using keyboard commands ?

Yes, I have. It doesn't work for me. The "copy" menu item is greyed out everywhere and that includes the edit menu and it's relative keyboard shortcut ⌘C

Not sure if it's specific to OS X but for what it's worth I am on 10.11.6 and Firefox 58.0.2

Copy in the right-click context menu is still enabled and works for me if I select multiple items in "Tools -> Page Info -> Media".

I see "Select All" and "Copy" in the context menu on Linux and both are enabled and not grayed.

Unfortunately not for me... see screenshots.

What operating system and firefox version are you using?

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
• do NOT click the "Refresh Firefox" button on the Safe Mode start window

Thanks cor-el. I switched theme to default and restarted in safe mode but unfortunately it had no affect.

Hi - unless anyone has a definitive answer or workaround I'm going to assume this is a bug and file a bug report. So far nothing suggested here works.

Call me stubborn, but have you actually tried what Pkshadow suggested :

Press Ctrl + C to copy and Ctrl + V to paste (and ignore that greyed out tooltip)  ?

Ok you're stubborn. And apparently didn't read my earlier response... here it is in a screenshot if that helps.

Also, please note the question details specify I am using OS X which does not use CTRL-C but instead uses CMD-C. A minor detail I know but the fact that this is the second response suggesting I use key commands that don't work in my operating system coupled with the fact that I am being asked to repeat things I have already posted leaves me wondering about the effectiveness of this support forum.

Bug has been reported: https://bugzilla.mozilla.org/show_bug.cgi?id=1452537

Not only am I stubborn - I am ignorant as well, cause I had no idea that on Mac 'Ctrl + C' = 'Cmd + C' ......

Please accept my apologies.

Good for you to file a bug report though.

Lol, well sorry if that sounded unappreciative. Thanks for making an effort - May I ask - can you confirm that it actually does still work in your setup? I just went and tried another machine running Firefox 48 on a much older version of OS X and it didn't work there either. Wondering if it's only broken on a Mac but works fine on WIndows.

I totally deserved it - I always get mad at others when the don't read everything that has been posted earlier in the thread. Pot => Kettle .....

Just went to the Media tab (only took a quick peek under that tab before) and get no option to copy and paste, only to 'Save as', which I did (saved the entries to my Downloads folder).

Ok thanks. Yeah, in most scenarios when I visit that window it's so I can quickly audit which assets are not being served over SSL when an https page is showing the dreaded broken lock. Occasionally there are hundreds of things in this tab and it would be great to be able to peruse the list in a regular text editor - hence my desire to copy and paste. There are other ways to get this data but in this tab is presented so concisely that it's really the ideal tool for the job. Just falls a bit short since I can't copy it.

Update - and again I owe you an apology :

I just went back to the Media tab - thought that the fact that I don't see that option to copy doesn't mean that it can't be done. So, I highlighted an entry, pressed Ctrl + C (Cmd + C for you) - opened a Word document, pressed Ctrl + V ........ et voilà  !
