I made a custom theme for firefox and submitted it to AMO. It's approved, but I have no idea how to actually apply it. I don't see any option to install or use. What am I missing? How do I actually use it?

I use firefox and duck duck go. I am able to access other websites but not my email. When I attempt to log in it "logs out" instead. I get a message that there is a potential security issue. I am able to access my email using non-firefox providers. I need help fixing this issue. Thank you.

Need to have my selected bookmarks in sidebar at all times...since update have to do it every time i open...want it to be permanent without constantly having to do it via selecting view etc

When I used a VPN I got this message

   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

How do I check?

Or does Mozilla have a vpn I can use?

Thank you Greg

I use an iMac and Macbook Pro. Autofill that used to work is no longer working on both of these when I go to USPS.com and sign up for updates on packages. It use to fill in my name on the top line and on the bottom line, it would fill in my email.

What can I do to get this feature back? It stopped working around the beginning of 2025.

Thank you, Martha.

Please give the option to have vertical tabs and sidebar functionality split into two seperate things. Much like with Edge and Vivaldi, we should be able to have vertical tabs on the left of the browser, with the sidebar on the right.

We should also be able to open any website in mobile view with the sidebar, again replicating the functionality of Edge and Vivaldi

I have a Mac Air and it is up to date. and I use Firefox browser which is up to date, but I suddenly cannot access a website to which I have a subscription which is paid up through November. The website is 'Mypilatestime' and now when I try to access it, it states 'forbidden' and is blank. I can access it on Google Chrome but Firefox is my preferred browser. Why can't I access it as usual? Please send a fix ASAP!!

I have a link provided by a web site I use. Through Firefox it takes me to a Mimecast authentication screen that asks for my email, then tells me to contact my IT department. This is my home internet. I can access the link through Safari. I'm stumped.

My Mozilla firefox is not working kindly resolve this issue . tms.nha.gov.in this site is not working on Mozilla firefox .

I cannot open the find on page toolbar. No matter if I use the ctr+f shortcut or click "find on page" in the menu, the toolbar with the text field doesn't come up. I checked and the shortcut works fine in other apps. I tried restarting firefox in the troubleshoot mode - the problem persists. I'm on the latest version of Firefox (138.0.1) and running Windows 11.

Hi,

A few weeks or months ago, Firefox suddenly wouldn't save my browsing history for longer than approximately 1 month. This is odd, because I have history turned on. I use custom history settings and only have cookies and cache deleted every time I close Firefox. Also, it does not delete the history upon closing FF, but it's simply limited to round about one month back. I have played around in about:config before, so I might have touched something there and not noticed until later.

I use Firefox 137.0.2 (64-bit) on a Windows 11.

Any ideas what might be the issue and how I could solve it?

Can someone please explain to me why the extension Video Downloadhelper works so erratically? It seems like it's gotten worse over time. According to Perplexity AI it probably has to with Mozilla's incessant updates; I have no idea if that's true or not, I just know it doesn't work very well anymore.
