Can’t Cut/Copy and Paste From Firefox

This week I’ve experienced a problem with Firefox after the updated they have been pushing. I was unable to cut, copy and paste from Firefox. I couldn’t copy URL’s, text from web pages or anything. I started Firefox in Safe Mode and the problem was gone. It appears that my StumbleUpon Add-on was causing the issue. Once I disabled it, the problem went away when I started Firefox in normal mode.

I have been regularly running into these problems with Firefox lately. I would blame the add-on developers, but other plug-ins have stopped working with each Firefox update. It’s starting to influence me to switch back to IE.

    Re-enabling Java fixed the problem for me. On the Firefox menu, select Tools, then select Add-Ons. Click on Plugins and make sure Java is enabled.

  2. Fran says

    Go to firefox preferences, select applications tab and scroll down to word document under the content type heading. If the action is “save file” change to “always ask” by clicking the action and selecting that. Should work then.

    for me, it was my Java Console addon, I disabled it then restarted FFox, and wow, back to normal.

    Every time there is an update for FF I have tons of problems. Now I can’t copy or paste in FF 4.01. I’d like to be able to. Any suggestions?

    If you have Windows Defender then get rid of that and you should be working good again. Won’t allow you to uninstall from safe mode though. And then go to your registry (only for people that know how to do this. Please do not attempt if you know nothing about registries as you could delete very important stuff), find Windows Defender and delete.

    I also had this problem, but after disabling framework assistant problem was resolved. Thanks so much.

    I also had the firefox Copy/paste problem; read about disabling the yahoo add on within firefox. on my laptop it worked fine afterwards, thanks to “Cody’s” advice. Thanks again.

  9. Constance Gravestock says

    For me to fix it, I hit “tools”, “add-ons”, and disabled Google’s toolbar for Firefox and that fixed it. Thanks for the direction I found here!

    well, well, well, It is definitely an add-on problem, mine was a $tupid “shockwave flash” add-on. So, what I would do guys is: I would go trough every add-on and disable them one by one and see which is the one causing the problem, by the way, FIREFOX STILL KICKS A$$

    I had the same bug, I checked my add on’s and found “ask toolbar” I uninstalled it and now it’s working fine. So yeah just uninstall your add on’s one by one and see which add on is causing it.

  12. Ryzor says

    I got sick to death of this problem so went searching for an answer and found it on this very page.
    All I had to do was go to TOOLS, click on Add-ons and disable the yahoo toolbar.
    Easy as.
    Been cutting & pasting to my hearts content ever since.

  13. DanGraphic says

    I disables the “ASK” toolbar add-on and was able to copy & past text in firefox (Facebook in particular) again.

  14. Dave says

    Framework 1.1 was doing it for me. I disabled it and the menu is now fine. You can still do ctrl+c and ctrl+v though regardless if menu is working or not.

    Firefox used to be a kick a$$ browser now is a stink a$$ one! It’s slower and less stable than safari.

    Sure in firefox you can customize features through extensions, but what’s the use if it makes you waste your time trying to look-up fixes to problems that should not be there? You just end up with a customized garbage.

  16. Chad says

    I have the SAME problem. Never figured it out so I’ve been spending hours retyping stuff. Firefix has really gone DOWNhill in the last 12 months.

  17. Bill says

    I disabled SEO For Firefox(v3.1.0) and the problem with not being able to paste in Firefox went away.

  18. Jackson says

    Disable all your add-on’s and restart ff then one by one re-able them and restart ff find out which one is causing the problem
