Firefox updated itself, and re-opened without all my tabs from the previous session. That session isn't available in history. Is there any way I can get these back? All my work was organised in tabs.

Note there are no enterprise policies in place.

I'm stumped. For years I kept Firefox on my Windows machine (Win10, 64bit, 8gb ram) at some level around 80x (I forget the number). I even recently switched over to Edge until I got fed up with its complicated design. So when I went back to Firefox, I upgraded to the latest 147.0.3 (64-bit). At first everything seemed okay. But then I noticed I was having trouble posting comments on any Washington Post comment section OR the whole thing would freeze up or other oddities. ONLY there. Everything else runs fine.

To add to the mystery, I walk upstairs to where I have a Mac (Sonoma, with 64gb ram) with Firefox 143.0.1. And I can post comments on the Washington Post, nothing freezes, everything works fine. So it can't be a problem on the Post's site itself.

Back on the Windows machine I have tried various Firefox settings, changing the permissions from strict to standard, changing the performance settings, turning Add ons off and on one by one, running in Safe Mode. But no changes change the problem on the Post comment section.

I'm at a loss to understand the difference. The Mac does have more Ram, but previous to my upgrade on the Windows machine, it was running the Post site just fine.

Hi, The last few times I have redesigned and uploaded my site (I use Weebly), certain pages do not show up on Firefox but do on other browsers. My site is www.devildoll.com and the pages: available, sold and commissions just show up as the grey box but the images do not load. When I look on Chrome, everything looks fine. Thanks for your help, Emily

I manually clear all youtube cookies. I have these youtube exceptions. After going to youtube, then checking "Manage Cookies and Site Data" I still see Firefox saved a youtube cookie.

Thank you

Hello, since your I have donwloaded your latest Firefox update I have multiple issues with Firefox 147.0.4 on macos Tahoe version 26.3

If you google "using firefox on mac os tahoe 26.3" you will see that I am not alone.

I have been using Firefox for many years, and do not understand why newer Firefox versions are not fully tested before being released on the "market".

You are not alone; Google has also the same problem on macos Tahoe version 26.3. Might be good to contact Apple to solve this issue,before a domino effect!

Cordially

Tonight when I went to join someone else's Zoom and he (host) allowed me to share from my screen, an issue arose that I am baffled about. The message was: Your browser is preventing access to your share screen." My Browser is Firefox. and it is up to date. How do I resolve this? Thank you very much!

Just to let you know, when I am host I can share. Would appreciate this help greatly!

Pretty sure I've got a problem with a fake certificate / server: in ISRG Root X1. > R13 >. "interfaithpowerandlight.org". This is a legit and very good org, but it ain't no server. A notification pops up intermittently on both mac and iphone that it can't be verified, at which point I've been clicking on cancel. Suggestions, please and thank you?

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.

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.)

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.

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.
