I have trouble installing the Yahoo toolbar and roboform in firefox. I keep getting a message saying the software is corrupt.
I am unable to install the yahoo toolbar and roboform. I used to have those before no problem. I have since got a message telling me that they are not supported on Firefox. I tried to uninstall and reinstall firefox but when I try to install either roboform or the Yahoo toolbar I get a message telling me that the software is corrupt and will not install.

Where are you trying to install that software?
Enter about:config into your Firefox address bar Click the I'll be careful button Find xpinstall.signatures.required in the list Right click the preference Select Toggle until the value is false

Update: The Yahoo toolbar add-on was updated on December 29, 2015. The latest version resolves the problem. If you followed instructions to change the xpinstall.signatures.required preference to false in the Firefox Configuration Editor (about:config page) as a workaround, you should reset the preference back to true, which is the default value.
