Firefox Support Forum

Hello! We distribute Firefox add-ons on PC and macOS outside of Mozilla store.

Until Firefox 100.0 our users were able to install the add-on by clicking a button on the product side which was opening a link to XPI file hosted on our company's download server. That was triggering a usual install dialog from Firefox where it asks user to confirm the installation.

Starting from Firefox 100.0 this stopped happening and we started receiving numerous support calls from our customers about not being able to install the add-on. The issue now is that when the XPI link is opened in Firefox, the install dialog does not appear which brings a lot of confusion to the user. Firefox shows the link to the XPI in the address bar but does not start the usual install process (attaching screenshot of how it looks like on my Mac). The issue applies to both macOS and Windows platforms. I've opened a bug case on bugzilla. The link for reference: https://bugzilla.mozilla.org/show_bug.cgi?id=1766965

Could someone please clarify how we should proceed with this issue? We are now getting reports of this issue from many of our customers. Thank you.

Dear Supportteam,

Today I browsed true the add-on list of Mozilla Firefox I was searching for Safepal wallet extension to use my cryptocurrency wallet also in the webbrowser. So my searching ended on the following page: https://addons.mozilla.org/nl/firefox/addon/safepal-wallet/ After I installed this extension and logged in with my credentials it was not working. 8 hours later I checked if my funds were still save on my phone software wallet also from Safepal I saw nothing $0,- balance I was deep in shock I saw my last transactions and saw that my funs ($4000,-) were transferred to another wallet. I could not believe it an add-on that is deployed in the add-on list of Mozilla Firefox. Is there no any audit department that is checking every add-on and test it before it get listed on the official add-on store of Mozilla Firefox. Can you please have a look into this add-on before there will be a massive amount of people getting scammed. And also have a look into the developer identity I have found the IP-address of the developer by tracing the mail address. Please have a look into it and maybe their is a solution to help me out.
