When following the instruction to sync bookmarks on Android phone it leads me to items that are not there. Open Firefox mobile on phone. Ok. Hit the 3 dots drop down. Ok. Choose sync and save. Not there? I click my email and it shows sync. I click that and it shows the last time I sync my phone. 0 minutes. Ok. It shows a QR code to scan from the Firefox app. It instructs to click ready to scan. That's not there either. If instructions lead you down paths that are not present, the instructions are useless. Anyone else having this experience? Thanks..........

I am not having trouble signing into any page except FaceBook, I just get a plain white page. I am able to sign in on my phone and a secure browser, but FireFox in my default browser.

Previous versions of Firefox turned a link from blue to purple once it had been clicked. The new update does not seem to have this feature. I would like it back, or an option to turn it on again.

Why was my browser upgraded. Did you save my configuration before upgrading? How do I get my info back? I didn't set up a account with my previous account. I did setup a account with the new upgrade when I noticed all my passwords were gone. How do I get my info back

The setting works...in the way that if i quit Firefox, it'll not continue from the tabs and windows, but if i reboot my pc and open Firefox, I find myself the same place i stopped...even though i have that setting disabled. I found someone else with same issue on reddit and i did the same restarting the browser and refreshing and all....all to no effect.

Hello! I am an avid user of firefox (especially with adblockers) on a windows 11 PC. Unfortunately, I have recently been experiencing an issue where when I attempt to open firefox, a window will open for a split second before instantly closing again. My PC is up to date, I have tried refreshing firefox and doing a clean install, but cannot seem to overcome the issue, or even open it in safe mode. Does anyone have any advice? Many thanks in advance!

Why is something claiming to be McAfee telling my that my Firefox browser is infected? And it's showing me a renewal notice when I do not have McAfee. It's all very annoying. If I download a new Firefox will that fix it?

Since the last Firefox update I cannot access sites such as Chaturbate or Myfreecams anymore with error message :

"Hmm. We’re having trouble finding that site. We can’t connect to the server at chaturbate.com."

There seems to be a DNS issue. I tried everything I found online such as desactivate DNS over HTTPS and others but I just cannot access these. Firefox works for "normal" sites and all other browsers (Edge, Oasis, Brave, etc) work fine now but I had to change the DNS after their last update (everyone created a problem from last week, so strange).

Another very strange thing is when I use a VPN, even with my country to access from, it is working !!!

What can be the issue and how to solve it ? Thanks

When using Firefox in fullscreen mode (via F11) on Windows or Linux, moving the mouse to the top reveals the tab and address bar. but this causes the page content below to shrink temporarily.

In comparison, Chromium-based browsers handle this differently: their tab and address bars appear as overlays, without disturbing the layout or causing any viewport resize. This results in a more immersive and fluid fullscreen experience.

Please consider implementing a similar overlay behavior in Firefox's fullscreen mode, or at least providing a toggle via about:config to allow users to choose between current behavior and overlay-style tab reveal.

When using any Microsoft 365 product on the browser I keep getting a prompt to "Please sign in" although I am already signed in. I can click the Sign in button and a about:blank page pops up for a split second. Then within a half hour or so, it will pop up again. I deleted my cookies but the problem still persists. Does not happen on other browsers.
