I am wondering if there is a setting somewhere in Firefox to automatically close tabs after a certain length of time or after there are a certain number of tabs open. I did not close Firefox. I was working on a text document in TextEdit and when I returned to Firefox, all of my tabs were gone! How can I deisable that if there is such a setting? This is a very vexing problem. Please advise. Please forward this to a supervisor for a quick and complete response. The representative I chatted with earlier forwarded my inquiry to Apple Support for an expensive subscription, which I do not want. Thank you.

My Macbook Air (M1, 2020) has be moving slowly recently. I wondered if how I'm using Firefox could be contributing. I typically have two Firefox browser windows open, with 5 or 6 tab groups each with several tabs.

In addition and more specifically, I'm wondering if closing (collapsing) a tab group means those tabs won't be contributing to my computer's CPU load. Thank you.

Hi. My Macbook Air (M1, 2020) has been performing slowly in recent days. I'm not playing video games or watching videos, just mostly working on many tabs in Firefox (157.0.1). I looked in my Mac's Activity Monitor, which shows that Firefox GPU Helper is using about 5.75 GB of memory. The next few highest users say "Firefox Isolated Web Content." Could any of these be what is slowing my Mac down? I'll attach a screenshot of my Activity Monitor. I also clicked "Share Data" below. I would say that my Macbook is working at a fine speed at the moment, so perhaps the screenshot and data are not so helpful. Let me know if I can add something later in a reply, when my Mac is moving slowly, that would be helpful. Thanks.

Amazon prime video won't fully load. I've tried everything, shutting off everything, dumping the cache. It fully loads on chrome. This is new since the latest firefox update... what is happening?

Hi I've used Firefox for decades. Now, since updating to Firefox 158.0 (aarch64) on my Mac Studio and a Macbook Pro, I’ve been unable to open my usual banking websites. They still work in Safari on the same Mac & Macbook Pro and through the banks’ iPhone apps.

Have any recent Firefox security or privacy changes affected banking websites? Which settings should I check, and how can I safely allow these sites without disabling protection for all websites?

Is it possible to add the File Edit History menu to Firefox for Mac? For those of us who have cut our computer teeth on DOS/Winders, not having the standard File Edit Bookmarks... menu makes it hard to navigate your Firefox for Mac application. Even if many of the File Edit commands are not there because Mac does not use anything remotely like the windows commands it would be nice to know exactly where the more standard commands are located on either OS. Commands like New Tab, New Window, Open File, Close Tab, Close Window, Save Page As, Print, Offline, Exit, Cut, Copy, Paste, Recently Closed Tabs\Windows, Bookmarks and Help would be REALLY nice to have their screen location standardized across all Operating Systems that you support with a firefox browser.

BTW... I still have FirefoxSetup-0.9.exe, FirefoxSetup-0.9.1.exe, FirefoxSetup-0.9.3.exe, FirefoxSetup 1.0.exe for windows... Need a copy?  :)

Until recent updates gmail worked normally but over the last several updates the screen is now impossible to read. In Safari gmail is still readable, This seems like a settings problem or a bug. Does anyone know if others are having the same problem or how to try to fix it,, or report it?

Updated Firefox browser for desktop on Mac to 158.0 on 10/15/26

On 10/14/26 using previous Firefox version 157.0 on Amazon.com Prime Video section, pages would load properly and videos could be played properly.

10/15/26 using updated version on Amazon.com Prime Video section, page would initially load properly only to later freeze. Videos could not be played. And freezing could not be corrected unless closing the tab on the browser.

10/15/26 using Safari browser on Amazon.com Prime video section, pages loaded properly and videos played properly.

Clearing cache and site data on updated version of Firefox did not have any effect. Pages continued to freeze and videos unplayable when starting over and navigating to the relevant pages.

Steps to reproduce:

go to amazon.com login to account go to prime video page

expected results video selection appears and user can select and play videos

actual result video selection appear but freezes after a second or two,. videos cannot be played

Repro rate 5/5

Other information Other amazon pages like whole foods and home page and Subscribe & save not affected Just Prime Video page affected

When I am using Firefox, which has been my primary web browser for years, I find that in the past month, in addition to opening the link that I want, a separate window with information on Alaska cruises or free shipping webpages, which I am not interested in opens. Is this happening to others, and if so, are steps being made to correct this problem. I am collecting some of the extraneous links that have been popping up,

After Firefox updated to 157.0.1 OS I no longer see where I can reload a webpage. The former icon to refresh or reload a page is no longer there.

How do I refresh or reload the page now?

How can I set a different home page for each container tab? It seems the default option is the same 1 home page regardless of which container tab it's in. But if I truly want to separate work vs. home by use of container tabs, then I'd like to default to different home pages.

When I go to the “Prime Video” page on the “amazon.co.jp” website, I can't click on any of the items.

In addition, this issue is affecting Firefox functionality, such as the home icon and refresh icon.

However, closing the “Prime Video” page resolves the issue.
