I understand that as from 14th March 2025 I will need to update Firefox. I am currently running 102.0 and have sucessfully prevented Firefox from updating to later versions. I did this to prevent the updates positioning the tabs in the wrong place. Please can you tell me if the CSS script that I use to put them back into their correct position, i.e. below the Bookmarks Toolbar, will still work.

Also, will newer versions allow the user to choose where the tabs are positioned? It was possible to do this in earlier versions and the choice is also available in other browsers.

I have also managed to stop Windows 10 updating for several years too, Microsoft kept altering my laptop in unacceptable ways.

I often receive a 403 error when using Firefox Every time, before this happens, I get the unsafe website warning and then the 403 error when I continue anyway

I am using the latest version at the time of writing These errors only occur on my desktop PC I have tried to replicate this issue on both my phone (Android) and another laptop(Windows 11) but all the websites work normally on there.

I have tried the following, none of which have any effect:

• Clearing cookies
• using Troubleshoot mode
• Restarting
• Changing Useragent
• Using "Forget about this site"

The following do fix the issue

• Using a VPN
• Using Google Chrome
• Running Firefox in another profile

Going through the privacy and security tab and reseting all the settings sometimes works but only temporarily

The following are a few websites where the issue occurs

Cannot Log on to Costco.com site after update to Firefox 133.0 in Win 10 pro on 2 computers. Both are up-to-date with latest software.

Entering valid account and password cause the Costco logon page to freeze for a minute then returns to log on screen with no messages about failure

Same behavior on two computers. Log on to Costco via Microsoft Edge works perfectly (on 2 computers before any trouble shooting ). Logon with Firefox 133.0 works with every other site that I regularly use - Samsclub, Amazon, Yahoo mail, my own mail servers, NYtimes, WashingtonPost, Google, Walmart, and others

Trouble Shooting Steps taken with no change in the problem logon to Costco + Cleaned cache / cookies + Disabled virus protections + Disabled firewall + Stopped all security services + Rebooted + In settings | Privacy & Security: Added Costco.com as Exception for Enhanced Tracking protection + In settings | Privacy & Security: Added Costco.com as Exception - Cookies and Site Date

After running scannow and chkdisk on my Win 11 laptop, the fonts for menus and toolbars in Firefox (not for web pages) is unreadably small (about 6pt). I have tried adjusting layout.css.devPixelsPerPx, ui.textScaleFactor, and browser.display.os-zoom-behavior to recommended valus as well as above or below values. So far, no help. Please advise.

Firefox would not open so I ran an old installer I had and now I've lost everything. No Bookmarks, no history, no add-ons. is there anyway to get it all back? Is everything in a file somewhere?

Hi,

I went to my local streaming platform Videoland (It's like netflix, a paid platform to watch series) And it's telling me the video can't play because my browser version is too old and I need to update it.

Of course, I checked and, well... my firefox is up to date. What could be the problem?

Thanks!

My firefox webbrowser used to update almost every time a signed in. It has not let me know it has updated lately. The last few days we are getting constant popups whenever we go online in Mozilla Firefox. Each of them has your logo & gives increasing warnings about a virus asking me to click on a link - We can either x out or click ignore, but have to do it 5 or 6 times.. over & over. I cannot snip it or print screen it as it disappears or just tries to copy the blank background.

I do NOT want to click on these links as it may well download a virus rather than remove it. What do I do? If updating Firefox will help, how do I do it?

On many site where I try to login, when I hit the LOGIN button nothing happens. This does not happen if I open a private window. I am on version 129.0.2.

The latest update also seems to force Firefox to occasionally run at turtle speed. Any time there is an update Firefox will slow the whole computer to turtle speed. When I reboot, Firefox can take up to 15 minutes to fully load if there is more than one window to load.

Is there a fix for all this? Thanks

Please look into fixing this problem. What is the purpose of the web search bar in the middle of the screen if it cannot be used? There is a setting that allows it to be there but nothing that can make it a default search bar. The address/search bar up top is always the default no matter what I've tried. It's nerve wracking to see something there you can't use. If there is something I can do to fix this please let me know.

Lately I have been having trouble signing into websites, including the website I administer. When trying to put in my user name or password, I get a message saying: Something's gone wrong. Please try again later." I do try later, and the same thing happens. However, I have no trouble signing into these sites on Opera.

Any assistance would be appreciated.

Thank you.

Yesterday, I get a screen popup that says" Outlook(formerly Hotmail)" Saying Hotmail will now be Outlook.

I've had Hotmail for maybe 30+ years now? I've always had Firefox open to my inbox, which is Outlook and has been for a year or better.

Since yesterday it will not open up to my inbox. It opens to the MS website showing what I wrote up above and a picture of Outlook.

I've deleted cookies and cache. Also history. Even though I point it to my inbox it just goes to that advertisement. I have the stay signed in box checked and don't show this again. But it does show again and again. I hope there's a way to fix this, pretty sure it not a Firefox issue. Just hoping someone else has had and and found a way around it.

Thanks Daniel B

Hi Firefox

I cannot view this document in full screen

Hello! I accidentally clicked to restore default setting in the customize toolbar menu, and now all of my tab/address bar/bookmark bar setting and locations are different and I don't like it at all. Previously, the address bar was above the tabs and the full length of the window. Now the tabs are at the top and the address bar is on the same bar as the bookmarks I have saved to the bookmark bar. The address bar goes full length if I remove the bookmark bar but I want to have both on the screen at the same time, on their own bar, as I did before. I have looked through the all of the settings and customize options, and can't find anything that will move my address bar to the top above the tabs, or a way to keep the address bar and bookmark bar open and available separately. Help! Thanks. :)

The E*Trade analyst research tab does not display properly with text appearing over top of other text, strange numbers, and certain links inactivated. See attached example screenshots showing issues (yellow highlighting with Firefox) and proper display (green highlighting with Chrome). Thanks!

When I start my browser, after a couple of minutes the search bar completely stops working until I restart it. When I type something and press enter it does'nt load anything and stays on the page it was on, and refreshing doesn't do anything either.

I work at a university. More and more, when ever I need to log into a webpage for work, I am getting a

Google Chrome works just fine. This is getting REALLY frustrating
