Here we go again. Apparently with this latest version 115.28 I no longer have an open new tab button on my tab line. How do I fix this and tell modifiers to stop changing things that were working fine.

The sites I visited most regularly used to show up in a row whenever I opened a new window or accessed a new page. But they have all gone. Also, the history that used to be accessible is no longer, it's as if I had no history.

the last 2 times I have allowed firefox to update my computer, it moves my icloud file to trash, the last time this happened to get my icloud to work I had to reinstall the Icloud on both of my computers and then replace the files. Why does this system always want to update?

A recent update (https://windowsreport.com/firefox-fixes-an-8-year-old-windows-bug-that-broke-virtual-desktop-use/) has broken behavior I previously depended on as part of my workflows: If I clicked a link in one desktop, it would open that link in the browser instance on the last desktop I'd used, so I could keep all my browser windows on one virtual desktop full-screened for easy viewing, then slide back to my other workspaces for messaging/writing/etc.

Now, apparently as a bug fix, every time I try to open a link on a desktop, it creates a new Firefox instance in that desktop instead of opening the link in the browser I have open on other workspaces. This has dramatically impacted how I work. How can I restore the previous behavior? It is so disruptive having new windows opening all the time instead of keeping them in my dedicated browser workspace. If there isn't a fix for this, I will need to move to a new browser.

I recently got a new machine and loaded it with Linux Mint 21.3 - Cinnamon, FF 142.0 and Bitwarden Version: 2025.8.2 along with the usual cadre of extensions that I use on every other machine I have.

When I first start Firefox, Bitwarden autofill suggestions does not work, autofill from the "Fill" button in Bitwarden does not work and returns an error. The only thing that works is to individually and manually copy the username, paste it, then copy the password and paste it.

If I log out of Reddit and then try to log back in, the autofill suggestions works and the "Fill" button also works.

This is only on Firefox and only on the fresh start of the app. This does not occur on Chrome and I have not tried (and don't want to try) it on Windows.

I am running the latest update for Firefox (143.0 (64 BIT) on a Windows 10 Dell laptop. Since the update on August 28th (prior update), my browser has been extremely slow, even with only one tab open. Task manager shows 95% memory usage after 15 minutes of browsing, and I have to end task on Firefox, then reopen the browser. I have run my Webroot antivirus and Malware Bytes, and my laptop is coming up clean.

I am not fond of Microsoft Edge, but I wanted to see how it performed. I have no issues with speed, so I can only guess that this is a Firefox issue.

Are there any known issues with the August 28th update?

In dem Sie das update in der bisher genutzten Sprache (Deutsch) ausliefern. Der Versuch den Firefox V143 auf Deutsch umzustellen ist mit der Auskunft gescheitert das Firefox V143 nicht mit "deutsch" kann. Wäre gut wenn sie einen Pätsch nachschieben der den Firefox in Deutsch auftreten lässt.

Firefox crashed and I restarted it and hit "Restore previous session". It started to do that, but then crashed again with a pop-up saying:

firefox.exe - Application Error A breakpoint has been reached. (0x80000003) occurred in the application at location 0x00007FFE1613B40E.

Click on OK to terminate the program

I clicked on OK. When I tried to restart, all my windows and tabs were not available and the "Restore previous session" button was gray.

Can someone fix this bug?

I prefer all my login accounts to log out when I close Firefox. All of my settings are set up to do so, nothing changed, yet suddenly for the last week or so, it has simply stopped logging me out. Every day when I log in, there everything is again. I keep rechecking all my settings, even turning them back off and on, and nothing is fixing this. What's going on?

I asked this same question in Reddit and got a reply to uncheck "delete cookies and site data when Firefox is closed", close all Firefox windows, and reopen them, and this did not correct the problem. Please advise.

your device identification does not tell me which devices you are actually identifying. You identify 4/5 devices, but I only have 2. - a new Nimo laptop (Rdn-Can68) and another relatively new Acer Nitro 50 desktop. Not sure what tag you have given for it. Previous systems failed and are gone. Some clarification would be nice!

Firefox is not saving my passwords. Every time I start up my laptop, all the saved passwords are gone. I have tried a refresh and a new install as well, but the problem persists. I have to sync to my other machine to restore them.
