Firefox Community Forum

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.

I recently upgraded FF on this computer and can no longer sign in to my att.net email account, although I was able to sign in on another computer on FF earlier today. I just get an error message and Att can't help...is there a setting that has me locked out? I can also access email on other browsers just not the FF version on this computer.

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.

The icons on my home page suddenly became significantly reduced in size. Sure, I can tell what they are, and I've increased the text size for their identifiers below the icons. But they are now so small as to be not pleasing to the eye. How can I put them back the way they wuz?

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

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)

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

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.

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

Update: Still persists in 136.0.2

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?

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.

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?
