I cannot type a | in Firefox. I had to cut and paste it in for this question.
On a Swiss Macintosh pressing the keys labeled <alt> <shift> and <7> producess a |, the 'vertical dash', sometimes called 'pipe' .. but not in FireFox.
The "keyboard viewer" agrees...
Entering [ or ] using <alt-5> and <alt-6> also doesn't work, but <alt-shift-5> and <alt-shift-6> do.
{ and } are also "broken" (=not what I expected) in FireFox.
Is this a known issue? and is there a solution?
I did google, but don't seem to find search terms google understands ... {, }, | and [ or ] are all ignored ...
