Few days before i tried to download a movie from some website i googled in, after which firefox behaved weird. It was not opening. As soon as i open the app within a sec it disappears from the screen. I tried reinstalling the app but it didn’t worked. Now i am not using it. Unsuccessful (Attempt 1): Movie file size 1.98 GB ( it didn’t stopped there i saw browser was kept on downloading more MB of data, So I have cancelled the download) Sucessful (Attempt 2): Movie File Size 800 MB ( it stopped at 800 MB) I googled “ index of movie” as advise by one quora website user & from their, i had clicked on one link to download the movie. Pls look into it developers.
