1. Some messages come to my mobile devices but not to my Mac. 2. I watch a message down load but it doesn't end up in my inbox or junk folder. 3. Junk folder says there are 14 messages in it, but when I open it, it's empty. 4. Yes, I'm up to date with Thunderbird. Also, the Mac is up to date. Problem began before latest updates. I have shut down the Mac. I have quit the Thunderbird application. No improvement. 5. I use Comcast for my ISP.

Using Facebook creates an "Isolated Web Content" which makes the page run slow then crash.

This has been happening for years, now and means I increasingly just don't use Firefox, switching to Chrome, instead.

This affects Facebook on my Mac (Sequoia) and PC (Windows 11) machines.

I've seen similar reports of this in the past. But I believe my case is different.

I had to reset a password tonight, requiring me to re-login to the account in Firefox. But, the tab/window would just freeze. I don't see anything immediately being blocked (ie: any DNS filter etc).

But, I CAN get it to work in Debugging mode, which suggests either there is an extension that is blocking it, or something else (some variable that is otherwise active in regular running Firefox). I just don't know which.

Has anyone else reported this and what might be the issue? I suspect uBlockOrigin (one), which I do use. But the other extensions I use are just for Youtube, IG, etc.

Thanks!

Up until a month ago, I was able to download gifs from the giphy.com as actual GIFs. What has changed in Firefox and how can I troubleshoot this so I can get the desired file format of GIF?

Dear Mozilla,

I use Firefox as my primary web browser.

I am constantly having to Force Quit Firefox in order to free up storage.

Please work on making Firefox handle storage better.

Unlike Safari, Firefox doesn't autofill passwords or 2-factor codes. Please implement these features or tell me how to get them to work. MacOS 14.4.1 Thank you, Steve

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

Michael

I've lost my bookmarks after Firefox restarted after computer crash today. The bookmarks library is empty, and I could not find another profile. I could not find "Old Firefox Date" on my desktop.

I'm on a Macbook Air, Apple M2, Sequoia 15.3.1

I have 4 macbooks and iphone w. about 10000-19000 bookmarks. Last n. I noticed what I bookmarked on 1 machine wouldn't show on another. A pop up said "your profile has reached a limit. A device can have ony one identity..make another (sic)...." I did that, and found the bookmarks from "classic" profile, WHICH I'VE HAD ABOUT 20 YEARS, weren't imported. I uninstalled, reinstalled Firefox, managed to get the bookmarks back via a desktop folder I'd made, thank god! It didn't restore the 50 passwords, and still won't accept the previous password..which is another can of worms-it actually won't let me change my p/w w.o "you may lose your personal bookkmarks passwords etc!:" Even the 32 digit code (which I had saved) is not working...and it doesn't let you get another one unless you have a p/w!!!! Is this sounding a vicious circle....I am going to not use sync or another profile, b'c I'd rather keep my personal data (bookmarks) and rightnow, I was able to 'restore' to the original profile!!
