Firefox Support Forum

When I attempt to download a large file, for example this one, Firefox often:

1. consumes my entire available Internet bandwidth, leaving other applications and devices unable to connect to the Internet, or even to other devices on my LAN.
2. hangs, i.e. the download doesn't show any progress in the Firefox UI

When I attempt to cancel the download, Firefox does not react. Even if I close Firefox, the download continues to absorb the entire available network capacity. The PC (runniong Windows 10 21H2) can not be shut down normally; I can only stop the process by pressing and holding the PC's power button to effect a hard shutdown. When I restart the PC and restart Firefox, Firefox automatically attempts to resume the failed download, with the same results described above. How can I prevent Firefox from hogging all available network capacity for downloads? How can I terminate hung downloads in a more elegant manner? How can I prevent Firefox from attempting to resume failed downloads the next time I start it? I am currently using Firefox 103.0.2. AFAIK, this is also the latest version at this time.

Hello,

When I open my application in Firefox, form elements dissapear, I see onlu blank page, but I have found that at the end of the <div> which displays form elements, I found the attribute <div *my_form_goes_here* style="visibility: hidden !important;"</div> at DOM. I wonder why this is happening and is it the fault of Mozilla or a bug on the frontend side of my application. But at the other browsers this problem do not appear. I tried to open the form in safe mode, incognito, no add-ons, tried to create a new Firefox account, tried without logging in, but none of these options gave the expected result - the tab disappears after I refresh the page. I am asking for help.

Every time I launch Firefox a message appears on the top right corner asking to update with the following text: "Update available Download the latest version of Firefox"

I have never followed this message for I've suspected fake, but it keeps appearing, and every time more and more often along the day (at the beginning it was only once per launch). This keeps occurring in spite of updating to the latest Firefox update (103.0.2) through the "About Firefox" top left menu on my Mac.

Please advise how to get rid of this annoying message. Is this a potential hack or virus attack?

I've only been having it issue since upgrading to Ubuntu 22.04. Firefox (103.0.2) will lock up (not the pc, it will keep working in other apps). It doesn't seem to matter about the number of tabs open, or what sites I'm accessing. It 'seems' random, and closing Firefox and reopening it seems to work for a short while before locking up again. I'm not a tech guru so I don't know exactly what to include here, like logs, or other info. The other issue associated with this issue is, when it locks, and I restart, Firefox does not start the first time I click on it. I have to click on it again and when I do, it will start, but usually (not every time) I get an error message along with the open home page of Firefox. I have to press the (not sure what to call it) windows key and switch to the error to close it. In the past, I've always had a great experience with Firefox, but this is starting to really be annoying! Especially when I have four of five tabs open and have to do a restart. Firefox doesn't seem to realize it's had a problem so the option to re-open tabs with a restart doesn't happen. So I have to use history, which can be troublesome and confusing, to get back to the pages I was reading. I only open multiple tabs most often when I'm researching an issue and want to 'order' the tabs so I read the ones that look like they apply the most to my research topic. So it really is an annoying issue. So much so, that I have been looking to switch browsers. But I really do not like the large commercial entities not to name names, but I may have to suck it up and install the Big G's browser, the Big C! )^: (note: if you respond requesting additional information, please be kind and offer how to obtain the info! Thanks!)

Recently I have noticed that my Firefox browsing keeps disappearing.

In my settings, I have configured Firefox to "Remember history" (see attached screen shot).

The history for my other browsers, e.g., Chrome are *not* disappearing, only for Firefox.

I have seen solution references to index.dat files, but I have found no *relevant* index.dat files on my computer's disk drives.

What steps can I carry out to retain my Firefox history?

Thank you

Hi,

I'm having a problem with Firefox Sync. When I started Firefox Sync it said disconnected, I logged in, exited the browser and reopened the browser and Firefox Sync was still working.

But when I shutdown, or restart the operating system, Firefox Sync gives an error that it has been disconnected, forcing me to log in again.

I have tried uninstalling, deleting all profiles in the %appdata% folder of the operating system and reinstalling but still the same error.

Hope someone will help me! Thank you!

Using Windows 11. I'm using a free Proton VPN. My Firefox version is 103.02. I want to be able to continue to use the VPN when using Firefox to check my gmail accounts. If I disconnect the VPN, Firefox lets me access my mail site without a problem. When I use the VPN connected, I'm getting a PR_END_OF_FILE_ERROR

Is there a way to keep the VPN on and connect with no error? Is there a Firefox setting I can change? I don't have proxy selected in Win 11 connections. Cache is cleared.

The last time I downloaded your update, I think it was in May, 2022, you apparently downloaded the version for Windows 10. It would not work with my windows 7. By the time I got it fixed I had lost ALL my bookmarks, history, etc. Now you are offering the latest download, I believe it is July. I am afraid to download it for fear I might lose all my bookmarks again. Can I just ignore the download. I DO NOT want to go to Windows 10 or 11. I am 95 years old and I like to stick to what I know. What is the situation with you and Windows 7 at this time? Are you no longer offering it? Thanks for your help. You may e-mail me at [removed email from public] PS Even though I supposedly had backed up my bookmarks they would not download to the newest Firefox. I have had Firefox since Firefox 1.0 (October 2004). In fact I still have the original instruction manual and the disk. If you have any need for that for your library I would be happy to send it to you. (In case you couldn't figure it out, I am a string saver). Marjorie Rogers

I see that form data for common fields like adresses and usernames are filled out for me. I don't like this data being stored except in my password manager. Keepass is the only one I trust because indie.

Where do I disable form data being stored How do I audit and delete stored form data

Hi, There is very little help if you can still log in in FB and Twitter but you lost all your feed and messages. It happened after refreshing FF. Switched both profiles in about:profiles. Logged out and in in both. All there is left is, check if Java script is enabled. Pretty desperate, but I'll try. So I am looking for my web content. According to this, I have to look for "list all tabs" under the "carrot icon". I can't find it.

All of a sudden most websites won’t open and I am getting the error message “Your connection to this site is not secure”. I am able to open Google.com and all of it’s links, as well as Yahoo.com. I am also able to open various random websites, but not all. I can open apple.com, but not support.apple.com.

When I click on the information provided for sites I can not open I see two things: 1) Verified by: Not specified 2) Technical details: Connection not encrypted

When I open Google for example I see 1) Verified by: Google… 2) Technical details: Connection encrypted

Obviously support.apple.com and support.Firefox.com are verified and encrypted website, so the problem must be on my end.

I have tried many fixes including clearing out cache, web browsing, unplugging my computer and modem, full virus scan, offline webdefender scan, system restore (which didn’t work), changing the DNS to 8888 and 8844.

I am using a Dell Desktop with Windows 10. Any suggestions would be most appreciated.

Thank you.

Every so often, Firefox fails to display a video. In this example, Firefox briefly displays what appears to be the first frame, then displays the message "The Media Could Not Be Played". I've tried with Troubleshoot Mode, and clearing history (cache, cookies, site settings, offline website data). How can I find out what's blocking? The example is a Twitter post on Wed 08/17/2022. I hope it is still there. https://twitter.com/i/status/1551522653705576449

When I enter YouTube and I try to see comments written to me, it says "'content filtering' has hidden the discussions on this channel". When I try to click on the button to cancel the filtering, it tells me that it cannot be canceled because the filtering is from the network administrator. "Content filtering Enabled by the network administrator to help filter videos that may contain adult content only." It blocks me from any discussion even if it doesn't contain adult content. I switch browsers, open Chrome, and there is no content filtering by the network administrator, but it does show me the discussion that Firefox blocked. Which means the ISP doesn't block me and neither does any other manager except the Firefox browser. I don't have another network administrator, I surf on a private network at home. You need to report the problem to Firefox and they will take care of it.

Thanks.

I've got an old Windows XP computer running version 52.9.0. I'm trying to sign in to Sync (so I can sync with my new Windows 10 computer) but when I try on the old machine I get this error message:

Blocked by Content Security Policy

This page has a content security policy that prevents it from being loaded in this way.

Firefox prevented this page from loading in this way because the page has a content security policy that disallows it.

I've signed in on the new computer, not that it matters.

Is the any way I can connect to Sync?

Disqus is not accepting ANY attempts to upload images and is fairly new...started rejecting image uploads a couple of weeks ago. Uploading still works fine on Chrome.

THIS is the error message:

Unfortunately your image upload failed. Please verify that your image is in a supported format (JPEG, PNG, or GIF) and under 5MB. If you continue seeing this error, please try again later.

Using FF 103.0 and Ubuntu 18.04. I tried again in troubleshooting mode...didn't help

(There are several sites that work well on Chrome but are glitchy one way or another on FFox. I don't like to use (or have to switch to) Chrome for workarounds!)

Is there something I can tweak on my FFox to fix this?

this has been a problem that a lot of us Facebook and Firefox user have and are facing and yet to be fixed. I have seen some people stare they're going to other browsers I do not want to do that but it is getting to the point where i may need to. It does not do this on Chrome or edge, Now it is said that it may be the extensions well I have disabled or turned them off and still doing it . Please could someone check into it was supposed to be resolved in newest version but it is not

When I close a tab, sometimes it crashes. I tried with `-safe-mode` and the error persists. Let me know if I can add more information.
