Let me be a bit more explicit: TenFourFox is based on Firefox
ESR, not on regular Firefox. The fact it works with 41.0.2 may
merely mean there was a bug in Firefox fixed between 38.3 and
If you're not willing to test it against Firefox ESR 38.3, then
this will need to wait until one of us can. I'm not planning to do
so immediately, since I have several other higher priority bugs to
deal with. If this is a priority for you, testing it (and including
the URL you tested with) against the build would be a great way to
start. I'm not going to look into this until I know one way or the
other because I'd rather use an existing bug fix instead of blow
cycles on a bug that's already fixed.
Thanks for that clarification. This is not a priority for me,
because I can always use 41.0.2 if I really need to save a Reader
View as PDF. I may install FireFox ESR at some stage just out of
Firefox 38 ESR on Win XP doesn't show this behavior when printing on paper. But printing errors should be tested against Firefox 38 for Mac. Since I don't have an Intel Mac, it won't be before the next weekend that I'm able to do this.
Slightly off topic but for future reference: I wonder how you found this bug at Bugzilla. Because I did a search before I posted my comment here and found nothing related. Even if I search for just "reader mode" in all bugs (open and closed) I get "10000 bugs found", but 1158322 is *not* in that list.
