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.

That is a change in current Firefox version that you can see as a regression and unfortunately you can't restore the previous behavior.

You would need an HTML capable editor to get the source code including the <LI> tags and see bullets.

Your system details list:

From Firefox 19:

    Next Generation Java Plug-in 10.17.2 for Mozilla browsers

Yeah I Know. I understand that the change was intended. But sometime you want text copied from a web page to have numbering or '*' attached to it so that it is easier to view it as a list and can be used accordingly.

I just wanted that there should be config option wherein the user can tweak whether the text/lists copied from a firefox page are reproduced accurately (without leading numbers or marks) or are pasted with formatting (with * for unordered lists and numbers for ordered lists) when I unicode paste it in MS Word document.
