Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options) key, and then starting Firefox. Is the problem still there?

While still in Safe Mode,

Type about:support in the address bar and press Enter. Under the main banner, press the button; Copy Text To Clipboard.. Then in the reply box at the bottom of this page, do a right click in the box and select Paste. This will show us your system details. No Personal Information Is Collected.

What stupid nonsense is this?

I want a browser that will work without my having to jump through hoops. If a browser---Firefox in this case---will not simply open, and copy, and paste, without my having to figure out "modes," then it is GARBAGE.

If there is a simple preference adjustment that can be made so that Firefox can work without my having to press a million buttons and go through some rat maze, great. If not, thanks for nothing.

I will add that this babble about "right clicks" is COMPLETELY USELESS if one is dealing with a laptop and a trackpad.

To repeat: Firefox does not copy/paste. It either can, or it can't. Safari can copy/paste using the pulldown menu, but it is not as stable as Firefox.

I would PREFER to use Firefox, if the damn thing can function as a browser should, without a bunch of side-trips for a simple copy/paste function. How do I get that

Before we can fix the problem, we first must find the cause. That means running checks on the program.

Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes). If the problem goes away, that tells us one thing. If it does not, that tells us something else.

Please follow the instructions I already posted.

I hope this answers your question; there is NO "reply box" at the bottom of the email I was sent.

You are running a very old version of Firefox. Please update. https://support.mozilla.org/en-US/kb/update-firefox-latest-version 42.*

Version 44, the latest I presume is not working with the select > copy, with or without the right click/context menu. Critical in my opinion! Besides that, Firefox is getting painfully slower with every upgrade, much too slow. It's a real shame.

How about checking out v43? Install an older version of Firefox {web link}

Come on, Fred! I came from 43, you're joking, right? The update just get installed so I will have to "update" to the older version to make it work? Is this even a solution? I can't believe how unprofessional this is!!!!!!!!!!! Man!

Does the clipboard only fail when you try to paste content that was placed on the clipboard by other applications?

Did you try to use the keyboard to paste?

It is possible that Firefox isn't recognizing the content that other application place on the clipboard.

When (in what Firefox version) did this stop working? Did it work in previous Firefox versions?

On copy there is no data in the clipboard whatsoever, with the keyboard or right-click > context-menu select "Copy". The problem is not from other application to Firefox, but from Firefox to any application. It doesn't work from Firefox to Firefox either. The funny thing is that it kills the last clipboard data from other applications, like I copied a big zero. I have this since version 44 (two days ago), obviously it worked before, otherwise I wouldn't be so bothered by this. It's a common practice, I noticed it right away.

Copy As Plain Text {web link} Removes formatting from copied text.

Problem solved with 44.0.2. Everything is fine, thank you.

New release hasn't solved it for me.

Any copy taken while in FF won't paste to my very old Word 97. (I'll be updating word when I get my new computer and this will remain a backup computer.)

It will paste to Wordpad and to anywhere else. But in Word it shows nothing to paste under the edit menu. It worked fine until the more recent FF releases where I see lots of people with troubles copying and pasting.

This is true for me too. I can copy and paste to Wordpad but not to Word. The edit...paste is faded off in Word, so it's showing nothing in the clipboard. It worked until a recent update.

Hi curls, Firefox 44 to Word 97 is your problem.

Firefox 44 reduced the number of formats it puts on the clipboard, dropping certain legacy formats. After release, several Word 97 users reported that Word 97 could not see any of the formats now available on the clipboard, and they had to use the workaround of pasting into a more modern application first, then cutting and pasting from there into Word 97.

This change will be rolled back in Firefox 45 (next month).

I've been seeing same issue. Usually happens when I restart Firefox or it crashes. Version: 46.0.1 OSX: 10.10

Rebooting the Mac fixes it though.

That next release did fix it for me. Meanwhile I'd kept wordpad open, pasted there, then copied again from there and pasted into Word. Your post helped immensely since I could then not worry about it.

Next step for me, buying a new computer and software!

Udheeraj - I would post this as a new question too in the help area. Since the problem here was fixed with FF 44 so your problem with FF46 may be something different.
