So, the system requirements system requirements for Firefox 108.x desktop only mention macOS 10.12 (High Sierra) through macOS 12 (Monterey)

Is Firefox lacking support for the latest version of macOS 13 (macOS Ventura?)

Hi, all just a question. The account is supposed to very very old. But since i logged in nothing has been there. I am taking nothing. So you help that be great. Thanks.

Hello! I've created a custom theme in firefox color, and I'm getting an error trying to upload it to the add-on developer hub. I downloaded the .xpi file and tried uploading it, but it only says Your add-on failed validation with 1 error. Received an empty response from the server; status: 403 I'm wondering how I can fix this, or how I can at least find my design that I saved within firefox color. I clicked on save, but when I tried making a new design in firefox color, it removed the old one. Now I'm having trouble finding my creations! If anyone can help I would appreciate it greatly :) Thank you. And as you can tell I am new to firefox color.

This is in the address bar when I open a new window; chrome://branding/locale/browserconfig.properties This is the message I get and have to open a new tab: File not found

Firefox can’t find the file at jar:file:///C:/Program Files/Mozilla Firefox/browser/omni.ja!/chrome/en-US/locale/branding/browserconfig.properties.

   Check the file name for capitalization or other typing errors.
   Check to see if the file was moved, renamed or deleted.

Why do I keep getting this instead of a fresh new window? It is annoying to have to open a new tab after a new window.

About 6 weeks or so ago, I began finding messages intermittently on my screen when I got up in the morning. It would state that Firefox had crashed and needed to be restarted or closed. It would transmit error information first in either case. Firefox has sent updates a few times since, and if I had the browser closed it would update upon being opened. The original problem is still there and now I have an additional problem. The first problem was a nuisance but the second is not acceptable. My email service is fastmail which I have used for many years. Sometimes I will open an email and need to click to go to another location. My problem is that I will click to do so and I get left with a blank screen and I never arrive where i am trying to go. It never reports any kind of an error. If I use Microsoft Edge everything executes as it should. That tells me there is no problem with the emails. the email provider, and takes the problem back to Firefox. When you sent an update you may have reset my settings. It seems like it sees opening the new page I am going to is likened to blocking a popup window. I am going to guess it is treating every page I attempt to open via the page I am on like a popup window. This problem is somewhat inconsistent. Sometimes it executes just fine. I get 80 to 100 emails each day and this feature not working properly is very aggravating. Example: I open a Kohls ad email or a Sam's Club ad email and click on the object I am interested in. However, all I get is a blank page and no errors reported. It may or may not execute properly if I go directly to the retailer and not through the email service. Yet it works fine if I use Microsoft Edge for the same procedure in the same email or even if I go to the retailer's webpage directly rather than through an email. Same results, Edge works fine, Firefox doesn't work. Help me out here please.

The old profile was on a Windows 8 installation. I have a complete copy of the original C-drive. I want to recover the profile to my current Linux OS. Or, if not possible, to a Windows 10 OS. I'm mainly looking for my saved passwords.

(I have the same question about Chromium browser btw.)

after updating I can no longer see pages of open tabs, just the one I'm on. If I go to customize toolbar I can see the old open tab view, but this is awful for me. I want the old behavior back

Why did you all of a sudden completely eliminate tabs? I don't want to have to click a drop-down menu to view my tabs, or now have to right click on a tab in menu to delete one. I just want to see tabs, as they normally should be, all lined up in a row when I look up at my screen. WHY did you change this?!!

I am mainly using firefox (108 at this time) in Linux Mint and I have sync setup with some others systems (even older linux distribs with icewease and windows). I have a lot of trouble with certain sites when my profile '~/.mozilla/firefox' is loaded and my sync account is connected or not. (seems to be related to javascript or similar - some wait circles never stop and nothing is displayed) I assume I have something corrupted in the profile. If move .mozilla/firefox profile and starts from scratch those websites are working good.

But I have a lot of bookmarks and does not want to restart from scratch. I already did that one year ago and it seems it when I restore sync when the problems arise.

Any idea?

I put a new browser on a new drive, and installed the new Firefox. When the new Firefox went to automatic update, it updated an earlier version. The updated version will not run on the os on that drive. So I downloaded the original version that I had, but it won't start because it cant find a profile. Well the old profile is there, in the user library firefox folder as it should be. Many passwords and preferences are stored on that profile. I could redo everything manually, but if I could access that profile it sure would be easier. Old browser was 78.15.0 for 10.11.6 new one in the trash... requires 10.12... thanks, Chuck

Just upgraded to firefox 108 and it has broken just about everything. No tabs. No real toolbar. No back button. No switching from fullscreen to windowed. Nothing works properly. The hamburger menu and minimized are on the same button. One of the toolbars constantly switches from arrow to plus symbol creating havoc on my screen. Can't watch any video because of this. Running Manjaro Linux.

My previous version of Firefox was upgraded last night in the new version I can not locate my previous bookmarks and associated log in, are you able to advise how i can transfer them over and where they are located? Kind Regards Steve

How do I set a Custom URL fora new tab under: "Settings - Home - New Tabs and Windows"?

Under "Home Page and Windows", there is a "Custom URL" option, but NOT under "New Tab". There is NO "Custom URL" under the drop-down list, only "Firefox Home (Default)" or "Blank Page".

I want to be able to set the default URL Home page when opening a new "tab" (as well as when I create a new window. For example, when opening a new tab, I want to set the default Home page for the new tab to be Google.com.

I am running a PC with Windows 10 and the latest level of Firefox.

On 12-8-22 I updated my email address in my Mozilla/Firefox acct. (I have an iMac w/Catalina operating system, but am using the latest version of FireFox.) Today is 12-15-22 & autofill is still inputting my old email address. I've been all thru FireFox preferences, "privacy & security" & autofill, but cannot find a way to make it autofill using my updated email address. I need step by step instructions on how to replace my old email address with my new email address in autofill.

THANKS in advance for any & all help!!

Not sure why, but the tabs suddenly moved to the bottom of my screen. How do I get them back to the top? Also, once I get the tabs back up top, how do I get back the plus sign to add a new tab?

(I'm on Firefox 108.0 in Windows 10 21H2. I believe the problem started when 108 loaded.)

Hello, when I search firefox in Ubuntu snap store I see two firefox: Firefox web browser V 108.0 build2 238.8MB and firefox v 108.0 250.5MB. There are both safe? Which one to install?

Some web pages don't work on FFx but do with Edge. On this page: link text I can fill out the form but when I try to submit it nothing happens. On Edge, no problem. I run into this a lot with FFx...

At least under linux, 'firefox' is now a directory in 108.0. For 106.0.5 and many versions prior, it was an executable.
