Since version 57 Firefox has been failing in fundamental ways and is worse with 57.0.3. Been using Firefox successfully for MANY years; this is the first time to be concerned. Now no drag/drop. No click to tab. Needs Google to open links, e.g. IMdb--won't respond to my bookmarks.

Is Mozilla no longer supporting my mid-2012 Macbook Pro?

Note: Any customization will revert back to default, you will also need to reinstall Extensions.

Refreshing Firefox helped. Thanks. Still miss the click to tab function that was available via Tab Mix Plus. Please consider making this a native function.
