'I am running fiefox version 147.0.3 in MacOS version 26.2. Every second time I start the program firefox tries to take 15GB of memory. The process does not respond (as this is equivalent to more than the memory available plus the swap space). I have to kill the process and the second time the program has standar memory needs. How can I help developers?

This is the most annoying behavior. For the most time I would like to use panel once or twice a day to ask some question to continue on conversation in some chat but whenever I close the AI chat-bot panel it resets its context and throws me onto the default page of the provider of my choosing. I have to click my way into the proper chat every time. Could a chat-bot panel keep its context or keep it session at the place where I left it?

Firefox 147.0.4 (aarch64) "hangs" for 30 seconds to 1 minute when I launch it on my MacBookPro (OS Tahoe.26.3). Itwon't open the simple web page I have Firefox set to open when it launches -- and I can't navigate to any other web pages. When I try to interrupt, I get an Apple spinning beach ball until finally, Firefox opens that first page.

After working with Apple tech support, I have disabled a number of content barrier Extensions in Firefox-- which Apple tech support felt might have been causing this behavior. Nothing works. And I hesitate to run Firefox without some of them.

I tried deleting my Firefox user profile from my computer, but all that did was prevent Firefox from opening at all.

How can I stop this?

After being able to view Netflix content on Firefox for, well, a long time, today I encountered audio with no video. Only a black screen. I contacted Netflix and they're telling me that Firefox needs updating - we tested Safari and it was able to play the entire content, video and audio. I checked Firefox and the info states the browser is up to date. I should add I'm on a Macbook Pro. The quality on Safari was not as good as Firefox has been so I would prefer not to have to use a second browser for one task. Can anyone provide some information on this situation?

Over the last 5 or 6 months, Firefox seems to have lost the capacity to remember my open tabs if my Mac is forced to restart. These open tabs are vital to my workflow. If this can't be solved, I shall have to migrate to another browser, which is something I do not wish to do.

My Firefox version is 147.0.4; my computer a Mac Studio 2025 M3 Ultra; my OS Tahoe 26.3.

Please advise.

The autofill card details isn't working. When I try to I get the message "You have no saved cards."

When I go into the Privacy & Security tab I can see that I have a number of cards saved correctly.

Dear Firefox:

My Firefox New Tab Page will not load properly in normal mode but it will load in troubleshoot mode. The new tab is the normal typical Firefox start page. It has multiple sections with links to many sites. These "links" just flicker. They do not fully load.

When I turn on troubleshoot mode, everything loads fine.

Thanks

Hi, please assist. My old Gmail account that I used to login is no longer working when I try to reset password. I don't have a 2FA push code (must have deleted this); however, I tried one of the 2FA backup codes which I do have (ten digit) to sync and access my old account and reset the password, but it is not working. None of the codes are working. Please help me reset and gain access to the account. Can you help me reset the password, and disable 2FA so I can get back in?

Best, Amritha

I have my browser.sessionstore.max_windows_undo in about:config set to 60 – it's been like this and working fine for several months.

It's set to this high number because I use an assistive technology which creates a fresh pop-up every time I deploy it, and Firefox treats it as a browser window closure when I close the pop-up. Consequently, I can easily rattle through well over 25 window closures in a day.

It's not necessarily that each window contains dozens of tabs and copious data, but nevertheless Firefox still treats it as a window 'within the meaning of the act'!

I just went to reopen one closed window from a couple days ago which did contain many tabs (partly why I closed it in the first place), only to find that the 'recently-closed windows' context menu is now only showing 20 windows (18 of which are the aforementioned pop-up assistive technology windows)

The really vital window that I want to reopen is not showing.

I've double checked in about: config and the browser.sessionstore.max_windows_undo is still set to 60 windows; nothing has been altered or reset.

I updated Firefox to 147.0.4 yesterday evening, but the problem existed before I updated Firefox, and is still in evidence since updating.

Two questions:

1) Why is the Recently Closed Windows context menu not showing the full number of windows it has been successfully doing with no problem now for months? I used to have to scroll down to access the full extent of the 60, but they were always there.

2) Why has it arbitrarily changed to 25 windows?

3) [I lied – Our chief weapons etc...] Is there a way that – given about:config still implies that the most recent 60 windows are retrievable – that I can access beyond the 25 windows limit that are currently showing as reopenable?

Thanks very much

(And yes, I already have things like OneTab and Tab Session Manager add-ons, but disabled those just before closing the important window, because I was trying to locate which add-on was draining the CPU. I assumed my 'recently-closed windows' buffer of 60 would suffice while I disabled the add-ons.)

I have an odd white circle with lines in it at about one o'clock on the Firefox icon in the dock on my MacBook. It just one day and I haven't been able to find any answer in Mozilla/Firefox web pages. I don't know if it means something i wrong or what. Thanks for helping

[Using Sonoma 14.6.1]

I have been having an issue with Firefox acting up after taking a screenshot - it's not EVERY time, but I need to use screenshots enough that it's a noticeable issue.

After the screenshot is saved, suddenly clicking on tabs "selects" them with no way to "deselect" them. This prevents me from switching to a new tab and sometimes even stops me from typing in the search bar. I have found no fix for this other than force quitting or restarting my computer completely.

Any help or direction would be appreciated :)

Greetings. Am running Firefox 147.0.4 (aarch64) on a MacBookPro running Mac OS Tahoe 26.3. When I first launch Firefox, it sits and does nothing for 30 to 45 seconds, I have it set to open a National Weather Service forecast page at startup, but even if I try to type in a different URL, Firefox won't allow me to do anything --or even quit the application -- until that first web page finally loads. Have tried clearing all history, including cookies and site data, but that does not help. The hangup was even longer until I worked with Apple tech support to turn off some universal add-ins like Content Barrier (Intego) or anything that acted like a VPN. Apple told me the hang is apparently caused by a Firefox add-in or extension. But I can't figure out how to find any or how to turn it off.

Emojis do not show on Firefox 146 on macOS. I downgraded to 145.0.2 and they do show, so it seems related to Firefox 146.

I have macOS 26.2 running in both test cases.

I reset basically everything to see if I could get it to stop predicting what site I wanted to go to and it still does it. Cleared the history, turned off syncing, closed tabs on other devices before I turned off syncing. I see on setting for autofill address bars etc. Mobile firefox settings are reduced it seems. I am on IOS if that matter. I don't know what else would be useful.
