Awesome ^^(This thread is a great reminder to look for an alternative for OneDrive!)
With the last updates, they optimized their PDF viewer, it should be faster to load PDF files now.Unfortunately PDFs were really bad in Firefox. So when I went to university and had to stand in line to print the course slides, it was simply too embarrassing to keep using Firefox. People in line would start sighing because I was so slow. I switched to Google Chrome basically immediately.
Indeed, however, it's mainly because Microsoft and Google intentionally slow them down on Firefox, in order to use either Microsoft Edge or Chrome. Which, are pretty much the same browser.However, the Microsoft websites don't work properly on Firefox, in particular Microsoft OneDrive is horrendous in Firefox.
That addon is a must whenever I browse the internet.I switched back to Firefox in 2024 because Google Chrome was giving me notifications that uBlock Origin would stop working soon and I just don't think the internet is safe enough without it.
