I clean installed windows 8.1.. then installed all latest drivers for my devices... installed latest Firefox.. Then i needed some images ..so opened Google image search and searched images..opened one image in a New Tab.. clicked "View Image" and tried saving it by right clicking and selecting "Save Image".. First it took a lot of time for the "Save Image" window to appear.. and then it hanged... I tried doing it again by force closing and re-opening firefox..but same thing happened even if the Image is small like 100X100 pixels.. Then I opened the mozilla support questions and tried the following solutions some other users have suggested; 1: Opened FIrefox in safe mode (Same thing happens) 2: Disabled addons (Only addons i had was flash downloader and downthemall! - Same thing happens) 3: Reset Firefox (No use) 4: Disabled Hardware Acceleration (No Use - In fact firefox hangs as soon as I "View Image") 4: reinstalled Firefox (No Use) 5: Uninstalled my ATI Radeon display drivers (No Use) 6: Disabled JAVA and Flash (No Use) So this problem still persists....and its quite annoying Another thing I have noticed is when i try to save/download other files like mp3 or email attachment or pdf .. The window where it shows whether to Open or Save the file opens immediately..but takes around 15 seconds before I can actually Select and option and click Ok.
