Firefox Community Forum

I have no issue with youtube on any other browser, but I do prefer Firefox. However, Fierfox says that site is slowing down firefox and suggests I close that page. Firefox did not do this in the past. Is this similar to the rather ugly color of the private window that I can't change, not being a coder? The impression I get is that Mozilla is making changes without assuring they work properly. I currently have to use chrome to make sure youtube works correctly.

How do I completely uninstalled Firefox and revert back to the previous version, and turn off auto updates?

All of the sudden can't use Hotmail through Firefox I have tried clearing cache, making sure clocks are correct etc.

This is the error page that I get. How can I fix?

I use Stockhouse.com as a homepage and when I opened my computer this a.m. the site came up and it asked me to sign in which it normally does these days and I click on sign in and it shows my email and password and I click again and I'm signed in. This morning it asked me to provide my email address and password i.e. fill in the blanks. It has not done that for at least 15 - 20 years. Not remembering offhand what my password was I clicked on the 3 line application tab in the top right hand of my screen and brought up the list which includes "Passwords". I clicked on the password file and it is blank. It has never been blank before -- did Mozilla/Firefox make a change that would make my password file disappear?

Hi, my PC had some hardware problem and al its data was wiped as procedure, so i had to install everything from zero, this includes Firefox, and when i did so i did the same as usual, download it, open it and log in to sync my data, but there seems to be a problem, all my data is gone, it says its synced and i try to sync it many times, no bookmarks, no extensions, no passwords, nothing, this is my only account too. tried to look up solutions online and saw people talk about 'old Firefox data' folder that can appear on the desktop but nothing for me, tried to go to about:profiles and see what profiles i had and switch to see if its in any or if the folder appears but still nothing, i don't seem to find a solution, i only got the PC back at the end of December last year, and its as far as i can see my Firefox activity here, but I've always used this account and I've synced in multiple PC's with no problem i don't understand what is happening now. thank you

I have recently started getting the message "Gah Your tab just crashed" when using firefox W11 lenovo laptop Up to date with updates Started yesterday (26/2) Happens most of the time now Seem OK on another laptop

Hi Guys,

I have an issue. I noticed now that if i click on one of my 300 tabs of website tabs, it automatically goes to some domain reseller and removes the whole link / information on the link that shows which tag or data i had on that link in the tab. If that makes any sense?

I hadnt yet gone through renaming all the tabs when the website changed domainbs and now i am unable to as the minute the tab wakes up from beind discarded, instead of coming up as can not find website (at which point in the past i could just change the 2 characters to the right domain), it goes to the domain reseller and removes the whole link / data that it used to point to.

Anyone know of a way i can do change the links on a mass scale of all the tabs i have?

When trying to log into my bank, I get the following message: "Bad Request: Your browser sent a request that this server could not understand". I have tried to clear cookies, to no avail.

Many websites that I use regularly, such as Zillow, no longer work correctly in Firefox ESR (115.33.0). The top menu in Zillow disappeared this week. Others work, but all the text is greyed-out. All except the text thing seem related to Javascript features. For instance, check boxes on a Wordpress site that I manage quit working last month. Some, like www.RCgroups.com just sit and spin, and never fully open up.

But they all work fine on an old copy of Chrome (109.0.5414.120), that is no longer supported on Windows 7 and hasn't been updated in probably 3 years.

My only plugin is NoScript, but the problem is the same whether it's turned off or not. And I also use NoScript on Chrome.

I use Win7 for the same reason I use Firefox -- it is safer, far more stable, faster, and it doesn't force updates on me that invariably break things. I appreciate that Mozilla has extended support for the last stable version of Windows. But somebody should look into this growing compatibility issue.

I have a profile that I had copied from my main profile, which is connected to an email and synced. This second profile is unsynced, and it won't let me sign into my account because that account is connected to the main profile. It says I need a separate account for a separate profile. Fair enough. I try to make an account. It says I cannot sign in to the new account because the profile is synced to the old one. Very annoying to be given instructions that don't work. So, I make a new profile and sign in to my new account on it. It works. But now I don't have my bookmarks and passwords. So I find instructions on backing up my account and copy my secondary profile into the new profile with the new account. It logs me out and is now giving me the same error! (the backup was successful though) I don't want to have to copy and paste all of my passwords and things into a new account. Is there any way to make my secondary profile syncable?

I've always used firefox

Recently it seems to me that a lot of sites don't seem to recognise me, so I have to do multi step logins.

Paypal for instance. I don't save the password, I type it in each time, but now it insists on sending me an SMS in addition

My guess is that FF is deleting some cookies that I'd rather it didn't. What can I do?

Thanks

Over the last couple of months, Firefox has automatically added Favorites to my home screen. If I delete one of these another replaces it.

Where do I go to stop this?

Why can't Firefox open .mht email extensions within its default browser? It has never done so to my knowledge. They always point to Internet Explorer or Microsoft Edge.

Often an email may not display images correctly and the ability to open them in a web browser is offered, "If there are problems with how this message is displayed, click here to view it in a web browser." This is certainly a development addition when people view their Gmail from Firefox or use Outlook. Not everybody uses APPS. People who don't want Microsoft Edge watching every move they make have made effective permanent changes in removing the deep embedded PUP by Microsoft.

Firefox version: 148.0
