I was doing some maintenance on my network devices and I could not get the password to work on my AP’s web interface in Firefox. To get the job done I simply used Internet Explorer and it worked OK. The solution is to change the Firefox Do Not Track setting. Here’s the whole chain needed to get there: Firefox menu -> Options -> Options select the Privacy tab and change the Tracking radio button to Do not tell sites anything about my tracking preferences.
I’ve had a problem with the LibreOffice Calc print preview function for a while. The problem is not showing the selected sheet(s) and I’ve always assumed it was more a problem with me than with the software. I finally got annoyed enough with my work around for the problem that I decided to search for an answer. The answer I found was 2½ years old making me feel even dumber for not looking sooner. So if you can’t get some sheets to show in print preview simply go to the sheets that do show and delete the defined print ranges (Format -> Print Ranges -> Remove). When you think about it this is the proper behavior, setting a print range tells Calc to not print anything else in the spreadsheet.
