Firefox recently updated itself on my laptop. Now when I ask for R help

"When Firefox starts Show my homepage"

I would guess that browseURL() won't work for any URL. Is that right?
Yes. That is correct. E.g. if I do
browseURL("http://www.r-project.org/";)
I get taken to my home page, rather than to the R home page.
What does getOption("browser") give you in R?
"/usr/bin/firefox"
If it is just a character
string (e.g. "xdg-open" is what I get in Ubuntu), does it work from your
command line, outside of R, e.g. for me that test would be
xdg-open http://www.r-project.org
I tried
/usr/bin/firefox http://www.r-project.org/
from the Linux command line and was taken to the R home page,
seamlessly. I also tried
xdg-open http://www.r-project.org/
and that worked equally well.
Finally I tried
options(browser="xdg-open")
and then
?plot
and BINGO!!! the HTML help came up as requested.
So I have a working solution to my problem. But I *really* don't
understand why changing the browser from "/usr/bin/firefox" to
"xdg-open" made a difference. (Since there appears to be no difference
at the Linux command line.)
Anyway; thanks very much for solving my problem.
cheers,
Rolf
If that doesn't work, but you can figure out a command line way to open
a particular URL, change getOption("browser") to use that.

The Firefox that I am currently running is (according Firefox help
--> "About Firefox") is version 36.0.
Can anyone suggest to me how I can get my html R help back?
For what it's worth: I am using Linux, Fedora 17. (Yes, I know it's
elderly, but then so am I. :-) )
Also in case it has any relevance:
