What is it you are trying to copy? text, images? What is the web address you are having problems with? What about other web pages?

i'm trying to copy text websites are some blogs and aliexpress.com other pages like facebook and google works great

aliexpress.com is mostly pictures. What are you trying to copy?

sellers send me updated tracking information i can't copy them to track them

I called for more help.

any more help any one can help

I don't have an account and haven't placed any orders, but other pages on the site seem normal for me. For example:

I have not received my order. What can I do?

Can you select/copy on that page and successfully paste elsewhere?

Maybe a blog would be an easier example (no login required).

no i can't

Might be few websites are restricted to copy information from there site ( I mean to say Ctrl+C function will be disabled).

these sites are working in other browsers and in firefox in another laptop

Could you test in Firefox's Safe Mode? In its Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Hold down the Shift key when starting Firefox.

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" button > Restart with Add-ons Disabled
• Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?

Do other selection methods work, such as Select All? You can either

• right-click > Select All
• Ctrl+a

Hi, could you give this quick fix a try : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :
