I just got my Mac back from repair, and I also put in a new 1 TB hard drive.

I used Migration Assistant to get my data across.

After starting Firefox I was inundated with "accept font" messages.

I agreed to all, but now I can no longer use Firefox. The letters I press on my keyboard no longer match what's on the screen. Online banking: instead of 511 I get ":jj".

How can I get Firefox to input what I type, not some crazy rubbish (which probably comes from a font problem).

I shut down Firefox twice, and the problem persisted.

Then, a few hours later, the problem is gone.
