Since a recent Firefox update all aspects of both of my computers run slow, not just browsing. Microsoft Word is slow and sometimes stops working. My photo editor is slow ...everything is slow and it all started about a week ago when I noticed that Firefox looked a bit different. What happened and how do I get back to the way it was? It was 5 years with no problems and now its awful. I tried a Firefox reset and it crashed my computer.

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test.

It is possible that your firewall or other security software blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to install for Firefox and the plugin-container process and the updater process.

Do a malware check with several malware scanning programs on the Windows computer. Please scan with all programs because each program detects different malware. All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.
