Firefox Community Forum

For the past few days now I've been getting a PR_END_OF_FILE_ERROR when I try to use certain websites such as Reddit or Tumblr. The problem occurs on both my PC and mobile when using Firefox. I can access the websites just fine using other browsers.

I've tried the solutions listed here: https://appuals.com/pr-end-of-file-error/

But none of them have worked. I've also tried renaming the 'cert9.db' file in my profile folder, but that hasn't worked either.

I make invoices for work and need to enter a dozen addresses every day. For every one of them Firefox pops up and asks if I want to update my address. No. I never do. I have the "Save and fill addresses" box ticked off, I've tried with it ticked on as well. How do I block this box from ever showing up? If I ever move I'll update it manually. This used to not be a problem but it just started happening recently.

I use Firefox on my Mac Mini. For some unknown reason, when my Firefox home page has changed from opening as a full screen view to a small box in the upper right part of my screen. Then I have to change it to the full screen view. I would like to find out how to get it changed back to always opening with a full screen view, please. Also, why is there no customer service phone number posted? Some of us prefer phone support, rather than typing questions and hoping someone knows the answer and takes time to respond.

For a credit card field, my card options show up. When I choose one it fills, but when I hit enter or tab, the filled info disappears.

It appears to be this (2nd) problem and known fixed bug. But it was fixed in v118, and I'm using v125.03 and it's still happening. https://support.mozilla.org/bm/questions/1416148 https://bugzilla.mozilla.org/show_bug.cgi?id=1817926

(I whited out the card numbers.)

If I want to edit a URL or type one in or just use the address bar as a search bar, the field converts to a light blue highlight as soon as I click on it. I am no longer able to see what I am typing or to check what is there. No type shows up at all, even if I highlight it, though I know it is there.

The first screenshot shows what I see as soon as I click on that field. Before clicking, I will see the URL.

The second screenshot shows what happens when I try this on a new page without a URL already in the bar. After a few characters, what I'm typing appears in a little popup right below the address bar. I assume this is normal. But if I want to see or revise a URL, I am not able to see it in order to do so.

I can’t figure out how to fix this! Any ideas?

So, my firefox is now starting to malfunction since i tried loggin in back, changed by passowrd, tried again and still couldnt't sign in fully. Is it a bug or a glitch, and is there any way to fix it?

no one can hear me in google meet (google's video chat website) on firefox only. I dont have this issue on chrome or safari or zoom. so its not the microphone. It's firefox. I had this same issue months ago and i reported it a few times and it was eventually fixed. and i dont know who fixed or how it was fixed. I've tried everyone's suggestions from New Profile, to disabling extensions. Nothing is working. If the issue isnt happening on safari or chrome or zoom, the issue has to be firefox. I'm using a 128gb Mac Studio M2 Ultra. Sonoma 14.6.1. Firefox 130.0.1 (64-bit). I wanted to test if the firefox issue was just with my desktop computer, so I went to my macbook pro this morning and went to https://meet.google.com/ and the website refused to load and just gave me 404 errors. See attached screenshot. PLEASE HELP ME FIX THIS, THIS HAS PERSISTED FOR AT LEAST 2-3 WEEKS NOW.

I can't find sometimes very important replies to my emails because they are filed not in the chronological order in which they arrive in my computer but are connected in the group of the original Subject. How can I change that? Thank you. info@rebel.gr PS. I use Win11

Hello,

I am writing about a unwanted window behavior that I encounter on KDE using Debian 12. When Firefox is half- or quarter-tiled to the screen, the tiling is undone each you click on the upper edge of the window.

Steps to reproduce: 1. Tile the Firefox window to one half of the screen 2. Hover the mouse over the upper edge of the window. The resize vertically icon appears. 3. Click to resize the window

Encountered behavior: The window goes back to the size and position it was before tiling the window.

Expected behavior: The window remains in place.

One additional behavior I discovered while writing this message is that: If you maintain the click and hover the mouse down, the window (which jumped to its previous size and position) returns to the tiled position and follows the resize movement (as intended).

I usually intend to switch to another tab when I trigger this behavior. I hover my mouse all the way up on my screen on (well, actually above), the tab I want to navigate to and click. While I agree that it takes is not to hover the mouse all the way up, it is very irritating that window jumps to another position so easily.

Other applications on KDE do not show this behavior. Therefore I assume this behavior is specific to Firefox. Furthermore when the window is maximized, this behavior doesn't occur (because these is no resize action available in that case).

About my System: Debian 12 KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.103.0 Qt Version: 5.51.8 Kernel Version: 6.1.0-25-amd64 Firefox: 130.0.1 (Installed using Flatpak)

Is this a behavior known to you?

Kind regards,

Nathan van Schoote

My computer died. Luckily I had all my Firefox passwords, favourites etc synced with my account. I got my wife's old computer, fired up and logged into Firefox expecting it to sync all of the data from my account onto this new computer, but, it seems to have now backed up all the data from my wife's computer and overwritten mine. Is there any way I can recover all of my original stuff please?

When i try to install firefox in userprofile silent i get the UAC prompt to enter admin password i usually have to cancel it for the installation to proceed. How can we suppress the UAC prompt to install firefox as normal user in userprofile

Several of my often-used websites are now unresponsive on Firefox. This has been happening for a month or so. I'm in the UK and on Windows 10 and Microsoft 365. More and more often I am having to use Chrome. I don't want to have to change over completely.

I am RE-ASKING this question because the person who responded to the previous iteration provided no help whatsoever. I'm using Firefox 130.00 on a MacBook Pro (15-inch, mid-2012) running Catalina (10.15.7). It has run flawlessly for years, but suddenly won't open, and only hangs, requiring me to Force Quit. It stopped working on Thursday, 9/12, which, I notice, was the day it was last modified with an automatic upgrade. I have quit and tried restarting multiple times, but am unable to get into it at all and, therefore, cannot access Troubleshooting Mode. I have NOT yet tried deleting it and downloading a fresh copy. I would like, if possible, to retain my open tabs, Bookmarks, and History.

Websites won't load. I had max protection and DNS enabled, it worked, then one day it stopped and I got an error that they couldn't resolve the DNS connection. So then I moved it back to Standard protection, and now sites load intermittently. Facebook loaded fine an hour ago, now it says "We can’t connect to the server at www.facebook.com." I have no extensions, not connected to a VPN right now, have tried restarting, and other browsers work fine.

Hi everyone,

I'm having trouble signing into YouTube using a specific Gmail account on Firefox. I recently deleted a YouTube channel associated with this Gmail, and since then, every time I try to log in to YouTube, I get the error message "Something went wrong." This issue only happens with this particular Gmail account and only on YouTube, while other Google services (like Gmail and Google Drive) work fine. Here's what I’ve tried so far:

   Cleared cache and cookies for YouTube and Google.
   Disabled all extensions in Firefox.
   Logged out of all Google accounts.
   Tried Incognito mode.
   Tested on other browsers (which work perfectly, so it seems isolated to Firefox).
   Signed in on a different device with the same Gmail (works fine outside Firefox).
   Checked Google account for security or account issues (everything seems normal).

Does anyone know how to resolve this?

Has anyone else faced issues logging into YouTube after deleting a channel, particularly with Firefox? Any tips or solutions would be greatly appreciated!

Thanks!
