The built in VPN worked great for me for a couple of months, but now whenever I try to turn it on, it starts with the "Get Started" screen, which takes me to a page to confirm my account. When I press continue the VPN button just goes back to the "Get Started" screen & the loop repeats. I've tried signing out & refreshing my Firefox installation but I keep getting the same result. Before it started doing this the button to turn on the VPN was appearing but would not react to clicks.

I do not care to see the "widgits" on my desktop opening page. It appeared a few days ago. I do not want to be obligated to its appearance there. A User of FoxFire should be given the opportunity to elect to have it or not. I do not remember reading that it was going to appear. I was concerned when it first appeared. Does it have to be there??? [edited email from community support forum]

I invoke Face Book but it FB page asks me to log in. Will not accept my user and password. Also You Tube is unstable. Only when in Firefox. Other browsers are OK, I can go straight in to site on other browsers.

We have an asp.net Blazor SPA (server side Blazor) that dynamically generates components within the page. Over time, there is a very large RAM leak under document-shared that climbs until the windows are closed.

We have tried various firefox configurations to try and either disable this shared storage as well as limit but with no luck. THe memory allocation is in GB of RAM space and cannot be limited or reduced until the window itself is closed/restarted.

Research online indicates this can happen due to colocated stylesheets and how firefox wants to cache styles aggressively. Adjustments to move stylesheets does not appear to help.

What configurations can I use to help prevent/reduce this high RAM usage? This does not occur in Chrome or Edge, I cannot replicate this well under FireFox for Windows.

When will the drag-and-drop link-to-open-new-tab feature be restored? Previous versions had this feature, which was very convenient, especially when wanting to open multiple tabs at once. Now it can only be done through the right-click menu, which is very user-unfriendly. I raised this issue a long time ago and never received a response. I hope this feature can be restored as soon as possible; otherwise, I will switch to Chrome.

I started using the new sidebar, but now when I type in the History search field, it doesn't recognize anything, even the most recent pages that are listed when I bring up History. I type any letter of the alphabet, and I get "No results for 'x'".

If I click on the three horizontal bars that say, "Open application menu", when I hover over it, I can click on History and then Search history, which puts my cursor in the address bar, and it brings up anything I type in just fine. How do I fix the sidebar?

I realize there have been several questions on this topic, even with the same subject heading.

The popup generally appears if you're trying to exit or refresh a page but haven't hit post or submit after entering data into a field. It's a good warning in case you've forgotten to do just that. I accidentally restarted Firefox after an update, and when I returned to the site I was working on I got this popup. Which makes sense, because I had entered in a ton of data and hadn't submitted it.

However, the page that I was returned to wasn't the one into which I'd entered my data - it was more of a home page for the website. I suspect this is a lost cause, but ... is it at all possible that the browser actually has that data saved somewhere and is waiting for me to complete submitting it? Or is this just a false positive?

Firefox has just updated on my Windows 11 PC at around 1100 17/06/2026 and now I cannot access my Spanish banking online with Banco Sabadell.

When I try to log in I get a message saying 'the process cannot proceed because of security issues.'

I could log in prior to the update and I can still log in using Brave.

By process of elimination I deduced that it must be something to do with the update.

I have a firefox account and I sync it to at least two devices. Now I need to change some settings. When I select the change, a prompt appears, asking for a confirmation code as expected. But I never receive a code on my e-mail. I tied many times, over the last days. I checked spam repeatedly. I added accounts@firefox.com to my contacts. What could be the problem? What can I try?

I am no longer able to open in Mac Preview or save when hitting Command + P, then 'print using system dialog'. It will only print instead. For instance, I save certain web pages as PDFs using the print dialog and now it will only print when trying to use either the save or preview options. Command + P, print using system dialog, then I choose either save as PDF or open in Mac Preview, but as soon as I do one of these it will only print. I am able to use save in the drop-down list of printers, but I need to be able to open in Mac Preview.

I'm generally just wondering if it's possible to remove the profile icons present in the top right corner of the Firefox app, and how to go about doing it if possible. Thank you very much!

With Firefox 151.0.4 on Linux Mint I can login to https://www.ftb.ca.gov/myftb/index.asp with username and password, then I get the message: "You may have pressed the back button, refreshed during login, opened too many login dialogs, or there is some issue with cookies, since we couldn't find your session. Try logging in again from the application and if the problem persists please contact the administrator. " . Accessing FTB with Chrome works.
