Hello I have just updated firefox 103.0 64bits on my pc windows 10. And bigs bugs : all web pages became huge zoomed at around 150 - 160% ! I managed to fix the huge zoom problem by installing this firefox extension : https://addons.mozilla.org/fr/firefox/addon/zoom-page-we/?utm_content=addons-manager-reviews-link&utm_medium=firefox-browser&utm_source=firefox-browser and setting all web pages to 90% zoom with it. But this is not a solution because firefox has to fix this bug since this update! :( And the toolbar has become much higher, which decreases my screen height, it was better before! :( See my screenshot where i circled in red the height of the toolbar which has become higher! :( even the tab bar has become higher! :( i managed to reduce it a little in height thanks to a code that i inserted in the file userChrome.css ,but the result is not beautiful : the texts are too flush with the line ( see my screenshot where i circled in blue the tab bar that i reduced with code in userChrome.css )
