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.

Hi,

I found some discussion related (https://discourse.mozilla.org/t/disable-add-ons-on-specific-website/33693) but no solution yet.

This is imho a big flaw in the privacy of users.

There are trivial cases, for example if I use a YouTube downloader plugin, I obviously want it to monitor my browsing ONLY when I'm on youtube.com...

And there are some critical cases: when I browse my web banking, or when I go on some trading website, I don't want my financial operations to be at risk because of an add-on that is very useful everywhere but on those site.

However, I don't want to exclude all the add-ons for those website too, that would be just too much.

I think there's already a coding base in place, since you can disable each add-on when using private windows. This could be enhanced by having a system of whitelist/blacklist instead. And this feature would actually make more sense than using a private window.

Another way would be to have this feature on per container, instead of per website, than would work well too.

People have different activities, and some requires useful plugins, that are very specific. I mean Keepass's add-on (for example) is useful everywhere, but many add-ons are related to one activity at a time.

For example, if I'm a marketer and want to analyze website, I'll use add-ons for having stats on metadata or keywords or even real time reports from Alexa or from AliExpress, etc...

But when I'm reading my email, I'm not happy those add-ons can see my data.

That would be tedious to disable all those plugins every time I change activity, especially since we are productive humans so obviously we need to alternate those activities doing multitask all the time.

And the private window option is not flexible enough for that kind of multitasking, when containers are.

I hope this helps everyone understand clearly why I think my request is not only a real user need, but also currently a flaw in users privacy since most people will not trade the comfort of their add-ons for some privacy concern they don't always understand...

I know this is some kind of feature request more than ask for help, but https://qsurvey.mozilla.com/s3/FirefoxInput/ is out of service so I don't know where to address my concern here.

Thanks for helping me pushing this idea forward.

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.

In Firefox settings, Firefox new tab, and in these mozilla forums, my add-ons are disabled. Specifically Vimium, and I get this message when hovering over the Vimium icon: "Vimium is not running on this page.

Your browser does not run web extensions like Vimium on certain pages, usually for security reasons.

Unless your browser's developers change their policy, then unfortunately it is not possible to make Vimium (or any other web extension, for that matter) work on this page."

How can I enable this, and possibly all normally active add-ons in these pages?
