Recently, I noticed that I had a tab opening in Firefox with the URL https://r.twimg.com/jot in a new tab. Apparently, when visiting RSS feeds in Thunderbird, this tracker is opened in another tab, which is quite annoying.
I've read a lot of solutions to this issue, most of them being changes in the settings of either Thunderbird or Firefox. Probably the best solution was to deny ||r.twimg.com/jot through ad block plus.
My solution was a quick hack: I fixed it by adding a patch to /usr/bin/firefox
if [ "`echo $@|grep r.twimg.com/jot`" != "" ]; then
echo jot stopped | logger
exit 0
fi
if [ "`echo $@|grep twitter.com/i/jot`" != "" ]; then
echo jot stopped | logger
exit 0
fi
