Hey there cycha. Is there an error message being displayed? If you have a print screen could you upload it for reference? Thanks Brad

Why uninstall, it may have been better to post from the problem Firefox browser but use Internet Explorer or Edge for the problem sites. If you are able to re install please let us have details of your Firefox troubleshooting page and the error message you see. Please also see * [[How to download and install Firefox on Windows]] * You obviously will '''not''' want Firefox as your default browser while you have problems: [[How to change your default browser in Windows 10]] * [[How to troubleshoot the error code "SEC_ERROR_UNKNOWN_ISSUER" on secure websites]] * [[How do I create a screenshot of my problem?]] * [[Use the Troubleshooting Information page to help fix Firefox issues]] ---------- Once Firefox is reinstalled then to find the correct solution to your problem, we need some more non-personal information from you. Please do the following: # Use ONE of these methods to open the Firefox Troubleshooting Information page: #* Click the menu button [[Image:New Fx Menu]], click on help [[Image:Help-29]] and select ''Troubleshooting Information''. #* Type '''about:support''' into the Firefox address bar and press the enter key. # At the top of the Troubleshooting Information page that comes up, you should see a button that says "Copy text to clipboard". Click it. #Now, go back to your forum post, right-click in the reply box and select '''Paste''' from the context menu (or else click inside the reply box and press the Ctrl+V keys) to paste all the information you copied into the forum post.
