pressing ctrl makes every page zoom in
Every time i press ctrl firefox zooms in (without touching my scroll button or anything else) I have checked with addons disabled and it does the same thing.
Just to clarify i am only pressing CTRL nothing else at all and it zooms in (NOT mouse related, nor addons)
If this is not a "mouse issue" then would you please try to press all the status keys (Shift, Ctrl, Alt) a few times to see if that helps ?
It could be that some of the status keys have the wrong state and that Firefox sees them as still pressed.
If it doesn't make a difference, then maybe reboot the computer.
Any luck ?
In addition to the above - probably a rhetorical question :
Have you made sure that the plus key is not stuck ?
Neither of those things worked, i also have a new issue on top since the restart again which is that now websites scroll back to the top of the page if i scroll down.
I have also replaced batteries in mouse and keyboard as well as checked the usb dongles and made sure it works ok.
Hello I recommend uninstalling and reinstalling FireFox. If this does not work, please contact me.

If you hadn't made it abundantly clear that this is not a "mouse issue", I would have suggested to toggle a preference on the "about:config" page. Now I'm just puzzled .....

I know that you ran Firefox with add-ons disabled when you were only dealing with the "Ctrl => zoom " issue, but as this a new problem, let's try Firefox in Safe Mode, to see if maybe one of your extensions could be causing this behavior :
If Firefox is not running : Hold down the Shift key when starting Firefox.
If Firefox is running : 3-bar menu => ' ? ' (at the bottom of the dropdown) => 'Restart with Add-ons disabled'. Then OK the restart. A small dialog should appear. Click 'Start in Safe Mode' ( not 'Refresh' !)
