A few days ago, we had published that the new version of Mozilla Firefox had been released, the brand new version 43 which brought numerous novelties.
The big problem with this new version is that Mozilla has decided to disable all unsigned extensions in Mozilla Firefox. This has of course been done by security reasons, which is always good and noble. The problem is that there are some useful extensions that are not signed and therefore will not work.
Luckily, a workaround has been released, allowing you to skip this measure no matter what operating system you have, be it Windows, Linux operating systems and Mac OS X.
Minitutorial of how to enable any extension in Firefox
- First you must write in the url address bar the words "about: config", this will open the browser configurator.
- Now look for a line where it says «xpinstall.signatures.required»Followed by true
- Delete the word true and write the word false.
- Restart the Firefox browser to apply the changes.
In this way, you will get Firefox to re-enable all extensions, whether they are signed or not. Also keep in mind that if you use Windows, you will no longer be protected against typical extensions that hijack the browser and that are installed along with other programs when you click next without looking.
The truth is that this Mozilla measure seems excessive to me, since although there are many malicious extensions that can hijack the browser or install malware, there are also others that are not, but are unsigned. What should be done is allow the user to do some kind of exception list and I hope they put it in the next versions.
There are rumors that in the next version of the browser, they will remove this option from "about: config" from it. Therefore this solution is for now just something temporary(I hope Mozilla will enable the list of extensions I mentioned above though).
