There should be a way to allow extensions to execute only on specific websites like the Site access option in Edge does, this improves extensions usability and may also enhance privacy.
3 years with significant community ask and? Seems like some ball dropping going on.
Come on this is serious issue. And I disagree with others who say it's simple, believe me extensions likely have tendrils all over the code and possibly this is quite a PITA to implement. But for firefox to have some semblence of privacy/security minded browser that it always tries to portray this is a complete must!
Alan here, product manager for Firefox extensions 👋. Thank you all for your feedback and for letting us know that this is a priority and what value it would bring.
Whilst it may be relatively simple to develop an access control list for where extensions can and can't run, creating an interface that guides users through how to use it is a very difficult problem to solve.
That said, in 2026 we will be providing a way for users to have more control over where and when extensions run based on the asks in this thread. We'll be delivering this in stages, creating the back end infrastructure first to support this capability, and gradually rolling out user interface improvements to make it easier for people to use.
I'll be posting updates on this thread as we make progress, so stay tuned!
@jcosta Yep, this is the feature I made my account for originally as well. I switched to Vivaldi for a while because of how poorly the apple password manager was working on one specific website when I use Firefox. The problem with profiles is that it feels really counterintuitive and tedious to have to switch profiles to just use one website because an extension you rely on is buggy on the one site. Its honestly easier for me to just switch browsers to use that website, and at that point I just end up using the other browser once
I can't wait to be able to turn off my password manager extension for just the one site that causes it to bug out. It would be useful for privacy reasons as well
Adding another comment for a much needed and welcomed feature!
It's kind of silly it took this long for something like this to be put into development. It's not like every extension we install is being used or even needed for every single website we visit. Yet for some reason they get permission to run on every single website most of the time. Restricting extensions in "private windows" and "sites with restrictions" was already a half-step towards this complete feature from many years ago.
I would like this too. I want to run my ad blockers on specific websites only.
Websites that I support could display ads. Websites swarming with ads will be blocked by my ad blocker. Now I have no choice but to run ad blocking on all websites even to those websites that have reasonable ads.
I would love this feature to be finally included! I have an adblocker installed, but I only really want it to be enabled on certain sites. It blows to have to manually disable it every **bleep** time.
Four years have passed since the community was informed about this idea, and it has gone through the stages of "Popular Idea", "Under Review" and "In Development" before finally landing on "In the backlog as a potential candidate in 2025" And despite Firefox already supporting MV3, we, as a loyal Firefox community, continue to wait with the (stressful) feeling that there is no progress in this area.
I, and I imagine many other users, would use many more extensions if it were possible to define their scope.
@alanmbyrne's words were encouraging, but let's be realistic, the situation remains the same. We see no progress, and it's disheartening to find ourselves lagging behind other browsers.
Is there any progress on this? Any realistic date?
