switching between tabs always having to reload
The page has been loaded before and switching back and forward without anything changing - it gets the loading wheel on it and Mozilla has never done this before unless the page actually does need to reload but never just to switch between tabs. it is aggravating that the tab switch cannot be fast and needs it done even if it is just seconds between each. the image is the constant loading icon i get
Even to load it into this question took forever and I am on a really good broadband connection

Hello lollywhelan, try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
- Click the menu button
, click Help 
and select Restart with Add-ons Disabled.
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.
To exit 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 others with the same problem.
thank you
Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) to see if that helps.
