Trying to add an extension my mypoints.com, I have the site allowed for downloads but when I try, I receive a message that it is blocked from being downloaded.

For the last few days after an hour (or so) of use, browser windows try to load but don't finish. I checked the Mac activity monitor and see that FirefoxCP webextensions is hogging memory--8GB! MacOS 26.6.2, Firefox for mac 154.0.1. Did the same thing for MacOS26.5.2. Is AI doing in performance? How can I find what to turn off?

if Mozilla Firefox will never support supernova SWF enabler or supernova flash player then firefox will kiss their user farewell & I was going to add that extension too

Would Mozilla consider an exception to the security-header policy for an extension that embeds user-selected websites within its own locally packaged page?

The proposed behavior would remove X-Frame-Options and CSP frame-ancestors restrictions only for those embedded pages. Ordinary browsing and other CSP directives would remain unaffected.

Vivaldi’s persistent Web Panels provide a similar user experience, while Chrome’s declarativeNetRequest API provides the technical capability to modify framing headers. I understand these implementations differ, but I’d like to know whether Firefox offers an approved path to comparable functionality.

Would explicit user consent and per-site controls make this eligible for an exception? If not, is there a supported alternative or a way to request a private, pre-submission review?

Здравствуйте! Есть вопрос: есть ли возможность управлять расширением вне браузера? Хотелось бы, чтобы горячие клавиши работали вне браузера. Я использую расширение для музыки, в котором есть настройка переключения музыки горячими клавишами, но вне браузера они не работают. Можно ли сделать так, чтобы они работали, когда браузер свернут? То есть расширить область их применения до глобального уровня.

Hello, I am trying to add extensions from addon.mozilla.org, and any one that I click "Add to Firefox" shows this error code:

"Installation aborted because the add-on appears to be corrupt."

A few months ago, I was able to run extensions no problem (For the ad blocker) until my Firefox application updated automatically and it no longer works. My Firefox continues to update automatically since then and I am not able to use any extensions unfortunately.

Any help would be greatly appreciated. I've been having to use Edge in the meantime, but I would prefer to use Firefox.

Thanks, Ethan
