I posted this and was told it was ;posted, but then I got a not found error when I tried to view it, so I'm trying again.

I set a site to use firefox as the default app for ftp not realizing ftp support was removed from the browser. I have been trying to get the dialog back that will allow me to change it. I downloaded filezilla to use for ftp. However, I am unable to get the dialog back that will allow me to change apps.

Can someone help me get the dialog back? And, before anyone suggests it, resetting firerfox to the default settings is not an option.

My bookmarks, history and passwords have disappeared. I looked at the articles, refreshed firefox, have restarted firefox and my computer multiple times but cannot retrieve them.

This is the message when I start firefox

The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

Hello- Wondering how to turn off the "skip to main content" that continually pops-up on some web sites. This is a problem on a single Firefox installation and I cannot figure out which setting this could be.

Thanks in advance! -BD

When I try to connect to MSNBC Live TV or Fox Sports Live TV while using Mozilla Firefox, I am asked to click on my provider (which is Verizon) so that I can verify my account. When I click on that icon (from a choice of 15 or so providers), it sends me to the Verizon page where the message is Please wait - we are verifying your account with a spinning wheel that does not stop spinning. How can this situation be rectified so that I can sign in. It worked fine for years until the last couple of weeks. Thank you, Raymond Birch

Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

On Sunday October 5, 2025 I began experiencing an issue with gocomics.com. I thought it was a temporary one that would resolve itself. Monday morning it was still happening. I contacted GC thinking the issue was on their end. They were unable to replicate it. They asked me to try to go to the site using the private window on FF. I was able to access it just fine. Therefore, we know it is not GC. I was also able to get to their page on Chrome.

I tried again on Tuesday. Same issues. I had already read on some forums where others were getting the same loop that I am: https://amub2c.b2clogin.com/amub2c.onmicrosoft.com/B2C_1A_GC_SIGNINSIGNOUT_POLICIES/oauth2/v2.0/logout?post_logout_redirect_uri=https://www.gocomics.com

It was suggested to try refreshing FF. I did that. Didn’t work. Gave up again for the day.

This morning, I tried uninstalling FF. Didn’t work. What else is there left for me to try?

My bookmarks toolbar is showing, but it's empty. All of my bookmarks are gone.

I went to a websites and attempted to add it to my bookmarks toolbar, but Firefox failed to add it to my toolbar.

Hi I have a firefox account which I use on 2 macs and a PC as well as an android phone. For the past few months non of my book marks, passwords etc are being synced across the system and I have now completely different book marks on different devises. I have synced each computer multiple times without effect. This used to work perfectly before I changed my password a few months back. It is now reaching a point that firefox is no longer usable for me?? Thanks for your help

My homepage saved sites are just not showing anymore when I start Mozilla or open a new tab. They are still saved but they are not showing up at all, I have checked about:config and everything is still there. I have tried following things: 1. restart Mozilla 2. restart PC 3. refresh Mozilla (this worked... for 1 day, I had to manually put all the saved sites again but they again disappeared when I turned on PC the next day)

However, if I enter troubleshoot mode, everything is still there and working. So I assumed it is an extension or a theme problem, which would be a great solve if I had any really. I have no extensions and I use the same basic theme that I start with. So I tried disabling hardware acceleration, didn't work. I am running out of ideas really other than switching to Chrome at this point.

Attaching files to show the issue. Not shown is the regular mode, the shown one is the troubleshoot mode

I am having trouble with my Midflorida bank loading information. I am using my desk top and it goes to a page that states I am using an app. Please help me.

Thank you

Yesterday while using Firefox my keyboard quit functioning in Firefox (Windows 11). I closed everything and restarted the computer. Everything else works fine, but Firefox would not load. I tried to the repair function and that wouldn't load. I tried to uninstall and that wouldn't load. I uninstalled with a third part app, and tried to reinstall, but that keeps giving a can't install message after trying for several minutes. I tried to install Firefox Beta and that installer hangs up at [Execute: "C:\Program Files\Mozilla Firefox\default-browser-agent.exe" register-task 308046]. Also cleaned registry.

its very distracting, would be very gratefull for any suggestones if any one can

How and where do I report when immersive reader mode renders a page incorrectly? What are the rules governing immersive reader mode inclusion?

An example is : Britain prepares NHS drug spending hike to stave off Trump tariffs

I am an academic researcher formerly affiliated with an institution that uses Okta as its two-factor authentication service for access to institutional subscriptions (think Elsevier, Cambridge Core, Brill, JStor, etc.). Since I am no longer affiliated with that institution, I am no longer authorized to access that institution's subscriptions. I am not trying to access that institution's subscriptions, however, if I try to log in to these repositories as an individual, I am automatically redirected to my former institution's Okta authentication page.

The browser: Mozilla Firefox 143.0.3. I am able to access other sites on other browsers, as well as in private Firefox windows, which suggests it is a problem with my Firefox account. These are temporary workarounds I can live with only in the very short term. I am under no circumstances willing to switch browsers. I use Firefox for a reason. FWIW, I am also contacting Okta support to see what they recommend.

The computer: Macbook Air 2020 M1. It is a personal computer. I do not have access to another device.

I have cleared my browser history, saved form data, saved site settings, cookies, and cache (x5). I have deleted all saved passwords containing the email address associated with my former institution. I have restarted the browser (x5). I have restarted my computer (x2). I have reached out to IT at the institution (they are flummoxed).

I'm nearing my wit's end with this. I'm working on multiple projects with multiple deadlines. The temporary workaround and constant barrier to access are driving me up the wall. I will be infinitely grateful for a permanent solution to this hellish problem.

Dear Firefox Team,

It has re-occurred to my Firefox Browser of the latest version of 115.28 with some websites which I have recently visited however which have appeared 8 grids of blank or white pages again under "Recent Activity" as attached with the image for your technical troubleshooting suggestion.

Those 8 grids of Recent Activity in the older version of Firefox browsers used to have shown colorful graphics or images representative of the recent websites I visited in the recent past.

May I know what I am supposed to do to recover those graphics or images?

Kindly offer any suggestion or solution?

Thank you for your kind attention.

I'm not able to uninstall PWA apps created in Firefox 143.0.1 using Windows 11 usual uninstalling procedure. If i click "uninstall" in Windows Start Menu the app remains installed. PWA apps created with Firefox do not show on Windows 11 installed apps list so I cannot uninstall them. I haven't found any guide on the web on how to uninstall PWA created from Firefox. So, how can I effectively uninstall those PWA apps? Thank you in advance for your kind answer. Regards.
