Firefox Support Forum

Starting yesterday firefox, no recent updates etc, gives a 403 error for several large corporate sites and 404 page not found for most paypal payment pages. These sites/pages work fine with Chrome. There were no changes by by myself to my firefox installation, not any antivirus changes.

Within the last hour today everything is working properly. What is going on? jn

I would like to be able to make sure if a pop-up window is blocked, that I'm being notified about it, but there are no options in settings.

I read through the instructions listed on the help pages and found a message from support from 4 years ago about manually editing the settings, which wasn't helpful.

Are they just on by default now? Or did they get turned off and if so, how do I turn them back on?

(p.s. having something teach you how to do something, this case getting trouble shooting data manually, should open another window, not navigate me away from the page I'm sending this message from)

Dear Mozilla:

It is SAD that the OS I have will no longer be supported due to exploits.

Considering the # of exploits, backdoors, poor coding, etc., in the later Windows OS versions - 1 would truly think that supporting the older and MUCH more secure Windows OS's would be wise.

Yes, they have "holes", but overall much fewer than current OS's.

Plus, the bad actors are very busy exploiting 10 & 11 and pretty much have ignored the prior versions.

Question... what if a major exploit is found that affects all OS's from 11 down to unsupported?

Will Mozilla make sure to supply a patch to the unsupported due to the danger of the new & serious "hole" found?

I vote... it would be wise to maintain a small contingency of legacy developers to help those who cannot buy new systems or flat out HATE the UI & UX of the 10 & 11.

Makes sense?

I had a few issues with Hotmail and Firefox in the past as described in other posts. Now it has stepped up a gear. I can use the internet for anything, but the moment I open my Hotmail account in Firefox my Lan card stops working. At first I had no idea it was Hotmail, I tried everything from switching cables to using wifi only. When it happened on wifi I realised every time I went into Hotmail on Firefox my network card stopped functioning and I had to restart the computer. The thing is, when I use Hotmail through Microsoft Edge nothing happens and all is well with the world!!! No network card shutdown. I could read between the lines but I'm no conspiracy theorist, however, I don't think the problem is with Firefox. Is there any solution? I don't use Edge and I don't want to start.

Firefox on my pc loads Ebay.com with Chinese characters, not English.

This ONLY happens on PC (mobile phone is fine, same firefox browser) only with firefox (Duck Duck Go on my pc works fine) and ONLY when opening Ebay.

Problem started 4/29. I have done: computer update/restart, firefox update/restart, clear cache in firefox

Thanks for any help. I also have Ebay looking into this.

When I open Firefox and want to go to Private. I go to the three lines at the top right of the Firefox page. I go down to Private. Then after selecting it, YET ANOTHER REGULAR FIREFOX PAGE OPENS. I NEVER had this problem until the start of 2024.

Please help as I used to have FIREFOX PRIVATE as my go to browser. Now, I use others and they do not work with some pages.

Please help as it is frustrating to keep getting a new Regular page.

Dear Mozilla Community,

I am reaching out to seek assistance regarding an issue I have encountered while trying to access the website https://paydayloanseloanwarehouse.net/ on Mozilla Firefox. The website does not load, and I am unsure whether the problem is related to browser compatibility, a technical issue, or a possible blocking by the browser.

Has anyone else experienced this issue, or can provide guidance on how to resolve it? I have tried clearing my browser cache and disabling extensions, but the problem persists.

Any help or suggestions on how to access the website smoothly would be greatly appreciated. Thank you in advance for your support.

I am able to start FF with no problem. I open a few tabs and then without warning I can't access any of the sites without closing FF and restarting. Then the whole cycle is repeated. I am considering getting rid of FF this started just over a month ago.

I'm using Firefox 124.0.2 (64 bit) on Windows, and every few days I get the error about using an older version of Firefox, with Exit or Create New Profile options. I then run "firefox -allow-downgrade" from the command prompt and everything works fine... for a few days, when it happens all over again. This only started happening a couple of weeks ago, but it's getting really annoying. How do I stop it (short of using something like Waterfox or Brave).

I have played "Hero Wars,Dominion Era " for years on Fire Fox...They did an "update" last week(Thursday or friday 04/25-26?24)and I haven't been able to log onto the game itself since...I can still open the Hero wars home page,I can get into my "discord" chat etc etc etc,but I cannot get into my individual game.(If it helps,my Hero wars game ID # is 10920140)...I had to start playing the game itself on Google Chrome...I am hopeing you can help find a solution as everything I do is from Fire Fox & I really don't like chrome :(...PLEASE Help me resolve this if possible! ( Nexus suggested I use "Incognito" on FireFox ( I remeber that from a few yrs back,but honestly,i haven't used or seen "incognito" since :()

"I'm encountering difficulties downloading APK files using Firefox. The downloads either fail to initiate or get stuck midway. I've tried various troubleshooting steps without success. Seeking advice on resolving this issue promptly."

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

WHY IT LOGGED OUT ALL MY ACCOUNTS FROM TABS WHEN EVER I CLOSE MY BROWSER, I HAVE TO RE-LOGIN AGAIN AND AGAIN, WHICH IS SO SO FRUSTRATING..................................

Hi,

Firefox Developer Edition 126.0b7 (64-bit) shows a perpetual "Loading" screen when trying to access my internal Logitec Media Server at 127.0.0.1:9001.

Other browsers like Waterfox Classic have no trouble, so LMS is working fine.

I tried cleaning the cookies, disabling the firewall (Windows 10), that did not help/

Any idea how to solve this?

Thanks.

I am autofilling an ELSA payment portal. Firefox autofills the payment information correctly. But the program will not recognize the autofilled information and doesn't let me process the payment. I then overwrite all my information and then it allows me to proceed with the payment. I have used the same procedure for years but as of this last week, the autofilled information is not recognized as I click the "Continue" button after the autofilled info is complete, and it won't work. The ELSA source (State of Wisconsin) person said it's a browser problem on my end. No. The online form autofills just fine. Can anyone help? Thanks. Jeff

How can I troubleshoot and resolve common issues with my Mozilla Firefox browser using the resources available on the Mozilla Support website?"

hi can anyone tell me how to get my saved passwords back into ff. they got deleted somehow by Clean Disk app

instructions ive found on web are for everything except what i need thanks

I am tired of this [removed] browser quitting, even when I don't have it open...I am going to uninstall it and NEVER install it again...I tried a full uninstall to see if it would fix whatever the [removed] issue with it was, but it is doing the same [removed] again!...I don't have this problem with any other browser I use on my system (Chrome, Brave, Opera and Tor)...I am tired of dealing with this [removed], so you can just take your [removed] and shove it!!!

How the hell does a browser crash when it isn't even being used???!!!

No need to respond and ask for any logs or other [removed], because it will all be gone!!!

Firefox just will not print anything at all. I have tried all the suggested fixes; everything else on my computer prints fine to either directly connected printers or to network printers. The 3 other computers on my home network all print to all printers from Firefox. I have deleted Firefox and reinstalled I have deleted all printers and reinstalled When I do try to print with the print queue open, the file spooling briefly splashes up and disappears quickly. If I download a PDF from the web, it will not print from within Firefox, but will print from Acrobat or Nitro I have changed antivirus from Eset to Webroot anywhere. No improvement and in between with no Antivirus, Firefox would not print. Any thoughts, as I had to change browsers and I want to get back to Firefox? Help!!
