Diễn đàn hỗ trợ Firefox

For a few weeks now, FIrefox will not play DRM content video on this computer. I have tried all the suggested solutions and none have worked. Also, I uninstalled and reinstalled Firefox, but the problem remains. I am very frustrated with this problem and am ready to get rid of Firefox permanently on ALL our computers unless this can be fixed.

Thank you in advance for your assistance.

This seems to be caused by Firefox. I don't have this problem with Edge, Chrome or Opera

Hotmail (Outlook) search function has not been working for months. I signed in using Chrome and no problem.

I realized search in my hotmail account was not working maybe 6 months ago and I've been finding ways to work around it, but today, i got upset and tried to figure out what was wrong. I signed out and signed in. I googled what to do, updated Firefox, to no avail. Then I read to try another browser. Chrome worked fine for outlook/hotmail search function.

I need this search function. I prefer Firefox. let me know if it can be fixed?

When I open the application it loads as a small window that I have to maximize to make it full screen. It never used to do this so I need some help to fix this. I've taken a quick look through settings etc and can't see anything wrong...
