Firefox doesn't let me install a dictionary toolbar from Collins. It says the toolbar "doesn't have a safe update system". But I want this toolbar so much! How can I install it?

I downloaded the toolbar from the Collins language site. I just searches and translates words based on the online content from Collins language website. Why is Firefox forbiding me from installing my toolbar?

You should contact Collins and ask them to update that Toolbar extension. It has been a few years now since Mozilla coded Firefox to reject extensions that have an updateURL that isn't on a secure HTTPS connection, for security purposes.


If you have that extension saved to your disk and it is in the XPI format, you could open that package with a "zip utility" program (like WinZip) and edit the install.rdf by removing the updateURL line of code. Also, look at the maxVersion line of code to see if it says 3.6.* - if not you need to edit that line too. When you're done with the edits, repack the XPI file without using compression. You can then try to install that XPI package using File > Open File in Firefox and see if it works in Firefox. Chances are that it won't, as there were other changes to Firefox at the time the "update only from HTTPS" was introduced.
