Firefox Community Forum

Hi. I have Windows 11. Firefox has been my default browser, and when I accessed a pdf document it opened Firefox, and displayed the pdf. I had to download Adobe to access a document, which didn't work, and I uninstalled it. However, now when I access a pdf it generates a new browser, and asks me whether I want to make Firefox my default browser. This doesn't work, so I now when I access my apps list on Windows settings I have 3 Firefox apps. Whatever I do to set defaults on only one of them, the other two don't go away, and every time I open a new pdf I get the dfeault message. It is really irritating. Have you any suggestions please?

Hi,

I've noticed that Firefox is no longer performing all the functions of some website. For example, when I use the Kaiser payment website, everything works until I enter my payment info. When I use the CA DMV app, it stops working after I enter the my username, password, and security code. In all cases, the website returns to the Login or Enter-Data screen. There are no error codes, just an endless loop of attempts to login or pay.

Firefox used to work on all of these websites. This error started happening on the prior-to-last update - currently on 135.0. It started happening before I updated my MacBook Pro to Sequoia 15.3. Still, the same thing happens on my Windows 10 HP laptop at work.

I am able to get full functionality on these websites when I use the Chrome browser. But, I like Firefox's functionality and security better! :-(

Out of 3 devices, one is not syncing at all. Here are my logs:

It says Login failed, but I have successfully logged out and back into my firefox account.

For about the last 2 months, when I either get a notification that an update is available or I manually check for updates, both Firefox and Thunderbird are stuck in "Downloading updates -- 0 bytes" on 2 Windows 11 computers. Eventually, like a half an hour to an hour later, the update downloads and I can install the update. This has been going on for 2 months now. As a 20 plus year user of Mozilla and also a long-time financial contributor, this problem going on for 2 months is getting old. And yes, I have checked my antivirus and firewall. Is Mozilla aware of the problem and is there a solution?

I haven't been able to do my online banking for about 9 months. I have to delete their cookies first. After that I can log on where I get a PIN. I enter the PIN and it will never work the first time. After the second PIN it asks if I want to save this device. After choosing that, logging off and immediately trying to log on again I have to go though all of those same steps.

The tech dept at my bank claims it's only Firefox and that it can't read their (your) encryption. I agreed with them that makes zero sense because I can always log on after jumping through enough hoops.

Is this something on your end or end my settings?

Hello,

I inadvertently used the option Block Element to get rid of a horrible recurring spam post on FB. I thought I was just blocking that post but what it ended up blocking the options on my whole Facebook program, so now I can't edit/undo anything on my FB page. I know it's within Firefox as it doesn't happen on the other browsers when I am using FB.

I tried to look it up but can't find anything to help me. I was hoping I could end up talking to a real person as I know it can get confusing but perhaps you can give me step by step instructions?

I need to know how to UNDO blocking an element. I've attached an image but I'm not sure if it fully explains what I'm dealing with.

Thanks, Ellen Claxton

Hello,

    I turned on sync on my home computer so I can reinstall windows. My work computer's firefox sync'd to those bookmarks and erased all my work bookmarks... is there a way to restore them? Thanks

Andrew

I always shut down my PC (Windows 11) while Firefox is open, and it reopens automatically when I turn it back on. However, the settings and the layout are reset.

I tried closing the browser normally via the Close button, but the issue persists.

I tried killing the process via Task Manager, but the issue persists.

I'm not opted into Firefox Studies.

I use quite a few extensions and also Container Tabs. I tried disabling all extensions, but the issue persists.

I just can't disable Container Tabs to test because I would lose too many tabs. Could Container Tabs be the issue?

For the past month or so, I'd say about 20% of the websites I visit using Firefox just show a blank, white screen. (See allbirds.com site image attached for example.)

1. Cleared the cache and cookies to see if that fixed it. It didn't. 2. Entered Troubleshoot Mode to see if that fixed it. It didn't. 3. Disabled all extensions to see if that fixed it. It didn't. 4. Disabled "recommended performance settings" and hardware acceleration--in combination with some of the above--to see if that fixed it. It didn't. 5. Reinstalled Firefox to see if that fixed it. It didn't. 6. Also paused/disabled VPN (Nord) and anti-virus (McAfee) to see if that made a difference. It didn't.

Any other ideas?

Thanks.

Hi....all of a sudden my firefox browser is not working. My home page will load in. But if I try to search for something all I get is a blank white screen. Can anyone help me out. I thought if I uninstalled it and then reinstall that might fix the problem. But I cannot find a way to uninstall it. Would appreciate anyone's help...Regards, Richard

I want links that I open (in Firefox, from Firefox, like opening any normal link) to open in the same tab (unless otherwise specific, like a normal browser should work), and all links from other applications to open in a new tab.

Whenever I click a link, it overrides my current tab, even if I'm working on something important. Apps do not always make it obvious what might be a URL. Windows for instance LOVES to open up "support" links in your browser. Firefox also does this itself with its update function, it opens up its update notification by overwriting your previous tab.

This is a really, really basic feature that should really be a default setting, but it doesn't seem to exist in settings at all.

I don't know what is happening, but for the last few weeks my Firefox has been freezing on me, I know the cause is not the website(s) because I can browse them fine with other browsers, also when it freezes it won't let me close it, I even tried to close it using Task Manager, but I get an Access Denied when I click End Task, so I have to restart my PC.

Any ideas qhat can be happening?
