Firefox Community Forum

Is it gMail or Mozilla that is slowing down the time for gMail to open a new Message? My internet connection is consistently between 200-300 mbps. Also, how to I change the email address on my account? Or should I just start a new account? Thank you.

When I restart Firefox, or my PC wakes from sleep, my Firefox windows are all in a different order.

Also a number of Firefox windows often just die or don't appear on restarting Firefox.

Is there a way to make sure that the Firefox windows appear in the same order and number as before?

At the moment I have to close Firefox windows and start them manually loading tabs from bookmarks. I would have thought that there must be a better way but I can't find it.

It seems as if Firefox should number the windows and keep a list of tabs open in each window, but this doesn't seem to be the case.

What am I missing? Is there a setting I need to change?

I'm running Windows 11 Pro

I cannot find the new built-in VPN or any icon to add to my toolbar. It was offered to me after update 150 but it only brought me to the support page on how to add it to toolbar. The icon is not at upper right corner of browser. And I found no way via Customize Toolbar to add the new VPN to toolbar.

To be honest. Firefox is starting to be a big pain to use. I'm starting to see more and more of this screen where it say's "Be careful. Something doesn't look right" Even when i go to the advance and say proceed. Nothing happens and i'm getting no where. I know many of the sites don't have anything to do with asking for credit card, Scam or even having popup's. I test the sites in other browsers and there work without any issues. But Firefox is starting to lock me out of many sites due to this. How can i make this stop. As i used Firefox for many years.

The sample that is in the screenshot is a Anime data base that i have also used for years. But today shows this. But was working fine yesteday. What is going on and how can i fix it. So i can start using the browser that i love on the sites i want to.

Starting a couple of weeks ago I haven't been able to open PDFs in my Firefox browser. Although there are other pdf viewers, Firefox has features that I use that the others don't. I've tried all the various ideas I've found elsewhere online but none worked. I submitted a ticket to our IT helpdesk, but they say it's a Mozilla Firefox issue. The error message isn't helpful at all, considering there is no web server involved.

I get the error below:

Access to the file was denied

Firefox can’t connect to the server at local file What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

updated to Firefox 150, What's New screen shows new free VPN and "Turn on VPN" box; sign in to Mozilla account, instructions to turn on VPN, but top bars show on signs on VPN --apparently VPN is NOT available to my computer (Macbook Air Sequoia 15.7.4) ?

Hi. Now that the 'Open Link in Split View' has annoyingly replaced the spot previously held by 'Open Link in New Window' i keep clicking on it accidentally (muscle memory).

I don't want to have to retrain my muscle memory, but despite creating css file generated by Claude that should in theory remove the option, and putting it the Profile Folder, it will not go away.

How do i remove it?

Suspected sessionstore.jsonlz4 corruption possible Sync rollback conflicts -

Please direct post to Sumo forum including jscher2000 or like-minded wizards.  Chat takes you down a never-ending rabbit hole.   Sync rollback conflicts - extremely large tab sessions spontaneous restoration of previously closed tabs during live browsing

Read several different instructions on Chatgpt that takes you down a never-ending rabbit hole. Firefox is restoring previously closed tabs from days or weeks earlier without user input during active use while typing in the middle of the keyboard with an activated red stylus mouse - used frequently and/or with an external mouse. The thumb pad is turned off. There are no shift, windows, 7 strokes. Upon restart of the computer, the Firefox settings are set to restore only active tabs open from previous session. This is a Lenovo T16 Thinkpad product no. 21HH003yus. The issue appears to be related to session restore corruption, possibly triggered by very large tab volumes (hundreds of tabs). Windows 11 that tabs reopen during active typing (not startup) hundreds of tabs open whether Firefox Sync is enabled ???? whether crashes/freezes occur - no whether the same old tabs repeatedly resurrect - no, but there are so many of them from weeks and months ago. whether you use session/tab extensions  ??? Believe recent version of Firefox or close.

Help please direct post to Sumo forum including jscher2000 or like-minded wizards familiar with suspected sessionstore.jsonlz4 corruption issues. Thanks so much!

I've been using MAC (multi-account containers) for a few months. Awesome feature, especially useful for logging into multiple email accounts in the same tenant (M365, GW, etc). In the recent past, if I had an issue with a particular login, I could go to the Firefox Multi-Account Containers extension button on the top bar, click on it...then Manage Containers, select the container to manage, there was a set of options, one of them being "Clear Cookies and Site Data" (or similarly worded). That would clear the data for that MAC which would resolve my issue. Now. that option is no longer shown when clicking the Manage Containers button. I've included a snapshot of what is shown now.

The ability to clear the data for that particular MAC is invaluable. How can I get that back?

MacOS (26.3.1 a). Firefox 150.0 (aarch64)

P.S. I just found the "Report" option on the extension itself in the Extension settings. I will post this message there as well.

I run the current version of Firefox on a Dell Inspiron laptop under Windows 11 Pro. I have around 8,000 bookmarks, and I try to keep them current. Every so often, quite a few (about half) of my tags disappear, and I have to spend two or three days restoring them. Why do the tags disappear, and how can I prevent their loss?

Browser shuts down within 10 -20 seconds of going to a website, and I get a crash report which I have clicked to forwarded each time to Mozilla.

Also have a new error message at the top of the browser that says: "The security sandbox is disabled. Your configuration is unsupported and less secure." (image attached)

Not sure if that is related or not.

I recently enabled Firefox's built in VPN. Signed into my Mozilla account, and when I toggle the VPN ON, every site gives "Secure Connection Failed". If I toggle the VPN OFF, it all goes back to normal.
