Firefox Community Forum

I use FF on desktop. Recently, I've run into a problem. My desktop browser will not load any pages... except Youtube. Youtube loads just fine, I can open a video or browse channels or community pages normally. I have fully reset my browser, reinstalled it, and disabled extensions. Other browsers on my PC will work normally. I have very few extensions: Sponsorblock for Youtube, uBlock Origin, and Facebook Container, that's it. I am not using a proxy or VPN. Troubleshoot mode did not fix the issue. I'm not the most tech savvy, so I apologize if I missed anything here.

Any insight is appreciated. Thanks!

Greetings all, my trusty Firefox stopped working. Error Code PR_Connect_reset_error. Other browsers work fine. I have windows 10 with the latest updates and use Kaspersky Internet Security 21.3.10.391 (m). I have paused Kaspersky, uninstalled then reinstalled Firefox 3 times. I have cleared all Firefox cookies and caches a number of times. On my 2nd Firefox reinstallation Firefox worked ok for a couple of times then stopped again with the same error code. Please note that I am not very familiar with computer stuff so any suggestions need baby steps. Many thanks.

Hi, In the last hour FF has stopped working completely. I made the mistake of using Ccleaner, which is probably the problem, I haven't had issues cleaning before, though I usually check the registry before deleting and don't recall seeing any entry for Mozilla (I may be wrong, though).

Firefox was working fine a couple of hours ago, but now it won't open at all, except in admin mode and then it won't open any links or tabs, not even settings. I've uninstalled FF, deleted the folder in the Programs folder, and reinstalled it from scratch, but there is no change (the one difference is that it wouldn't open in Admin after before I reinstalled it). Waterfox doesn't open either, but Thunderbird seems to work with no problems.

Thanks, Matt

WHEN I SIGN INTO MY OUTLOOK ACCOUNT, FIREFOX IS BLOCKING MY CONNECTION. IT WILL NOT CONNECT TO SECURESERVER.NET. I CANNOT ACCESS MY E-MAILS IN FIREFOX CURRENTLY. PLEASE HELP! ALL THE TECH PEOPLE SAID IT IS THE BROWSER????

I AM HAVING THE PROBLEM ON THE OTHER COMPUTER. I THINK THIS PC IS O.K.

I've asked about this before but got no help Firefox is my browser of choice. Occasionally, I find in necessary to use Chrome.

The vast majority of time, when are both are active at the same time, one or both crash, like today. Firefox closed abruptly, then the crash report appeared. I have the crash report. Chrome froze up, and had to be shut down in Task Manager.

It only occurs in this scenario. Rarely does Firefox crash otherwise.

Can someone please advise where to go to get help?

I don't know what's happening but since a couple of days, let's say Wednesday 13th November, my firefox got incredibly slow: everytime I insert a url or a link in the address bar and press enter it takes a lot of time to completely load the website.

I tried to use Edge instead, and Edge is working flawlessly, while Firefox is not.

I also did a fresh install, wiping the %APPDATA% folders too, but nothing changes.

Setup:

• Firefox version 132.0.2
• on Windows 10
• Firefox and Windows are 64 bit

During the past week I have been receiving 408 Request Time-out errors on a subscription website our organization uses. The vendor reports no changes to the site and no other customer complaints. All searches I've done point to my local browser or network setup, but I've cleared cache and cookies and it's not my network; I'm currently on vacation and getting the same errors 3000 miles from my home. It has worked fine for the past six months until last week.

I'll have to stop using Firefox if this continues. Please suggest some ideas why this suddenly started occurring and how I might fix it.

I often receive a 403 error when using Firefox Every time, before this happens, I get the unsafe website warning and then the 403 error when I continue anyway

I am using the latest version at the time of writing These errors only occur on my desktop PC I have tried to replicate this issue on both my phone (Android) and another laptop(Windows 11) but all the websites work normally on there.

I have tried the following, none of which have any effect:

• Clearing cookies
• using Troubleshoot mode
• Restarting
• Changing Useragent
• Using "Forget about this site"

The following do fix the issue

• Using a VPN
• Using Google Chrome
• Running Firefox in another profile

Going through the privacy and security tab and reseting all the settings sometimes works but only temporarily

The following are a few websites where the issue occurs

Cannot Log on to Costco.com site after update to Firefox 133.0 in Win 10 pro on 2 computers. Both are up-to-date with latest software.

Entering valid account and password cause the Costco logon page to freeze for a minute then returns to log on screen with no messages about failure

Same behavior on two computers. Log on to Costco via Microsoft Edge works perfectly (on 2 computers before any trouble shooting ). Logon with Firefox 133.0 works with every other site that I regularly use - Samsclub, Amazon, Yahoo mail, my own mail servers, NYtimes, WashingtonPost, Google, Walmart, and others

Trouble Shooting Steps taken with no change in the problem logon to Costco + Cleaned cache / cookies + Disabled virus protections + Disabled firewall + Stopped all security services + Rebooted + In settings | Privacy & Security: Added Costco.com as Exception for Enhanced Tracking protection + In settings | Privacy & Security: Added Costco.com as Exception - Cookies and Site Date

the following files couldn be attached outlook web Microsoft Outlook in firefox. Its files more 1 MByte. clearing the cache did not solve the problem. Outlook web in Microsoft Edge no problem with attach files Firefox version 133.0 (64-біт)

My son's email messages are being blocked. As far as I know he is the only one. Also, when I try to open a site from the email function, it just keeps searching... This appeared about two weeks ago. I searched for "Blocked Email" and only one has been blocked; a conspicuous spam.

My Firefox on windows 10 crashes tabs OFTEN. Mostly is seems to be Facebook and YouTube tabs, but other tabs will crash and this morning, the Firefox start page tab crashed. I've done "refreshes", I've uninstalled and deleted the folder and re-installed, I've checked the SSD for errors. Nothing appears in the event viewer. Is there some way to definitively figure what is causing this?

You Tube will not go full screen. I've tried reinstalling, clearing cache, refreshing page, pressing F11. Nothing works. It will go full screen in a private browser, but not in a normal one.

There used to be a way to add a web site as a shortcut to the Home page by dragging the link and dropping it somewhere. Those instructions seem to have disappeared. One of the sites I had pinned to the Home page has changed. I can remove the old link (tile), but how do I add the new link as a tile? The help articles no longer provide any information about how to do this. Just "pinning' the page adds it to the toolbar, where I don't want it, but does not add it to the Home page. Do I have to just close and open that site a bunch of times in order to get it to appear???? There should be a more sensible way.

I have every about:config and settings option set to recommended to prevent autoplay videos. NONE work with yahoo. The vids will drop to the lower right hand corner but even if I click on the close window X they still pop open again. And again. And again. Is there a solution to this arrogant, self-centered behaviour by yahoo?

The extension ZoneAlarm Web Secure is preventing safe downloads from web sites. I do not want this program in my version of Firefox. version of Firefox. There is no way I have found to remove this program. Please advise me how to do so.
