Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

• You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
• Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

Just read my issue one more time and realize wut I'm using FF for android. P.S. I haven't got any plugins or addons.

Sorry for that.

Hold on text and you can cut, copy and paste using clipboard

Try firefox Beta

Yep, i can hold and copy/paste, but it is not comfortable. And other browsers are support key combinations, but ff is not.

Try with FF BETA/AURORA

I'm using the latest beta build of FF

Firefox for Android does not have keyboard shortcuts yet. We are working on getting basic editor shortcuts soon in nightly.
