Firefox Support Forum

A few days ago I got the new Firefox version 103.0.1. And now áll websites I visit are larger than they were before, I didn't change anything and zoomlevel in e.g. about:preferences is still 100%

Now, with all the websites I visit I have to manually change the zoomlevel to 90%, to have them at the same level as before the update.

What do I have to change to have the zoomlevel set permanently at 90% ?

I've tried numerous times the "solution" Mozilla gives me: "Change zoomlevel in about:preferences to 90% but that doesn't work: no matter how many times I close Firefox, and restart, or restart the entire computer, it still defaults to 100%, and I still have to change the zoomlevel to 90% for each website I visit.

I have searched for "How to share tabs between profiles" in firefox.

I was offered this option:

Share multiple tabs

   Visit the tabs tray by tapping the number next to the address bar, this number shows how many open tabs you have:
   Tap the three-dot menu button in the tabs tray.
   Select Share all tabs.
   The list of tabs to be shared will appear.

Visit the tabs tray - not very clear. by tapping the number next to the address bar - which number? I have more tabs that can fit across the screen and am not seeing any number/s.

Could someone help me with this please? I have a lot of migration to do.
