Since Firefox 50.0 Beta 1, I can no longer download from mega.nz without all open tabs crashing and showing the message: 'Bad news first; This tab has crashed'. Is reverting back to Firefox 49.0 possible and will it solve the problem? Or will perhaps using an earlier restore point resolve the issue? Thank you!

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

Is the problem still there?

While still in Safe Mode,

In the address bar, type about:crashes<enter>. Note: If any reports do not have BP in front of the numbers/letters, click it to submit them.

The crash report is several pages of data. We need the report numbers to see the whole report.

Using your mouse, mark the most resent 7 - 10 crash reports, and copy them. Now go to the reply box below and paste them in.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)
