checking box within a Tab on yahoo mail will immediately open that entry and then freeze further operation until the screen is shut down. This happens on my wife's HP lap top i5 Pavilion 4.00 ram. ie: inbox tab will show a number of email - a dozen or so - followed by grey empty areas. The tab indicates 100+ total in inbox. Selecting one box opens the email but locks up any activity on that email & must be shut down to exit. The identical situation happens when I access my email on her machine. She is using Firefox 105.0.1 HOWEVER, on my machine, HP desktop AMD A8 8.00 Ram, both email addresses do not lock up, multiple boxes can be checked and work as expected. My desk top uses Firefox 104.4 This began happening within the past couple of weeks and I can not debug the situation. Any pointers ??
