Firefox Community Forum

unable to load X.com. Shows Firefox Enhanced Tracking as "strict". in FireFox settings, it show i'm at "standard, not Strict". Have refreshed tabs as instructed. No change. Still cant load X.com.

Since I upgraded from FF128-esr to FF140-esr I always get the "Firefox is being updated by another instance" This is really driving me crazy, as I checked / did / .... everything (and even more) I found on the internet related to that.

Nothing helps !

Creating and using a new default profile didn't help

Finally I ended up uninstalling FF completely (making sure no -zero- leftovers remained in ProgramFiles, AppData a.s.o.), and reinstalled FF140.7.0-esr freshly. After installation I started FF immediately with the created default profile (only existing one) --> SAME THING : "Firefox is being updated by another instance"

And this is really a FF140 thing, when I go back to FF128, on the same computer, same profiles, ...., the problem is gone.

I would like to know in detail what checks are really done by FF to decide to give that "Firefox is being updated by another instance"

It is been like 6 or 7 months now since i move to new pc and i been using firefox in this new pc together with other browsers. I am not really using firefox for anything related to google or gmail but just other website that have 0 relation to them. But i have still logged in my main accounts in firefox. It is been twice that once in a while, when i have to check my gmail accounts, all of them disappear and all i see is just sign in page only. There is no log in again or Please log in to this address or that address but straight up fresh page of google sign in page. I still logged back in when it first happened because i heard about the bug that happened with firefox update but now it happen again. It is as if my cookies just vanished but no, other sites still got their own cookies and there is many cache of other website here. other than my google accounts. What is happening here. Is my firefox bugged or something? Should i reinstall and have to relogin everything "again?"

The instructions for changing country in built in VPN do not work as after clicking on icon it states open VPN and nothing happens to open it. I am trying to set France as my country.

I can't log into my Google account using Firefox. Can log in on Chrome using the same device so I don't think the device is the problem. It was fine until about an hour ago. When I attempted to click on a YouTube tab the tab closed. Any attempt to log in redirects me to a Google support page about deleting my cache and cookies. Which I've already done multiple times and I still can't log in.

I tried to login to Autodesk for some discussion about file retention, etc. I logged in using my user id and password and then Autodesk sent me a code as a two factor identification function. When the page opened the place to enter the code it looked like the image that I have attached. I could not enter the code supplied by Autodesk as FireFox kept trying to get me to do something with email masks. Is there anything I can do to fix it?

Has Firefox's interface gotten smaller? The tabs and search bar are much more difficult for me to read now, and the symbols are extra tiny. I cannot figure out how to enlarge them, since zooming in only affects individual web pages. I tried looking in Settings, specifically the Accessibility section, but I cannot find a way to enlarge this part of the web browser. Help!

When my computer starts up and launches Firefox, the window is small and requires me to click on the full screen button. Before this it was opening at half-screen. Before that it was opening at full screen, which is preferred. I cannot get it to open in full screen despite all of the suggestions from this community. It's super-annoying. Why is this happening? What is the fix?

I am a novice and have not modified any code, but have added the extensions Duck Duck Go, Last Pass, Facebook Container, and Clear Cache. I have used these extensions for years and the problem is new. My problem must be a setting because I have not lifted the hood of Firefox or the OS and tinkered with it. Nor do I want to.

Running Firefox 152.0.5 on Mac OS Tahoe 26.5.1,

I have just moved from an old laptop to a newer one - a Lenovo Thinkpad. I have installed Linux Mint and successfully transferred my files and Thunderbird. I also synchronized Firefox and all my add-ons, bookmarks and history came across perfectly. While setting up the toolbar from the customise screen I dragged the home page button onto the toolbar and it just disappeared. The home page is set up in settings. It appears the first time I open a window. I would like to be able to go back to my home page at will, how can I re-instate the home page button?

Firefox keeps shutting down and it will open up when I tap on the icon. I have to reload it to make it work, It seems like I have to do this everytime I shut the pc.

It all started when I deactivated my account. When I click sign in I'm getting:

HTTP Status 401 –

type Status Report

Description http.401

I've tried clearing cache but I still get the same browser. I've tried a different browser and go to the sign in page to enter my account/pw but as soon as it finishes logging me in I get the same error.

when searching from the address bar (see picture) the first result (before firefox suggests) is not a bookmark and not history. what is it and how do i get rid of it? I want bookmarks to always be the first result. I just went through the library and it doesn't appear in history/bookmarks. thank you
