I tried to open my Firefox browser, but was unable to. Same thing with my Google chrome browser. I ran the troubleshooter for network problems, but unable to get a solution.

I downloaded a new Firefox browser in the hopes that it would let me access the other browser so I could retrieve all the settings, bookmarks, etc. However, everything disappeared when the new browser was installing.

Is there any way for me to retrieve that information or is it a total loss?

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.

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 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

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.

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 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!

This is a feature request - not sure if it goes here.

I would like to arrange the toolbars in Firefox in the following order:

   Menu bar (top, with "File" on the far left and "X" on the far right, i.e. not centered)
   Bookmarks bar
   Search bar
   Tab bar

This can't be done currently. The best I can do is:

   Bookmarks bar
   Search bar
   Menu bar
   Tab bar

My request is that the user be able to arrange the position of the toolbars in any arbitrary order. Thanks!

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?

I am trying to access the link "https://www.sorn.service.gov.uk/". This is the address of a click through from the webpage "https://www.gov.uk/make-a-sorn".

I am on Windows 10 Pro 22H2 19045.5011, using Firefox 132 (64-bit), not running Kaspersky, I do have AdGuard (7.19.0 (4853) (CL 1.16.44, DL 2.5.41 )) and Malwarebytes (4.6.17.334) on my system along with their browser adons. I have attached some screenshots, hope they are useful.

Please help.

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 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

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)

We are currently considering using Firefox ESR as our default browser but experiencing a few issues and one of them is with our configured SailPoint IdentityIQ Single Sign-On Experience, which uses Basic Authentication.

Issue Description First, the login button needs to be clicked multiple times before access to the site is granted. Once signed in, the Firefox inbuilt authentication dialogue appears, prompting the user to log in again (see the attached screenshot). The landing page is only presented after clicking the login button several times. This creates a poor user experience, sometimes causing pages to load improperly. Interestingly, the same process works seamlessly in Edge Chromium.

Troubleshooting Steps Taken I have already attempted the following: 1. Temporarily disabled all custom and security settings in mozilla.cfg and config.json. 2. Temporarily disabled Firefox Tracking Protection. 3. Allowed third-party cookies for the specific URL. 4. Upgraded Firefox Version to 128.7.0 5. Since our Firefox browser is significantly hardened, I have also enabled and reconfigured the following settings in mozilla.cfg to ensure Basic Authentication is allowed, functions properly, and suppresses Firefox’s authentication prompt, but without success:

network.http.phishy-userpass-length = 255 network.http.use-basic-auth network.automatic-ntlm-auth.allow-non-fqdn network.automatic-ntlm-auth.trusted-uris security.enterprise_roots.enabled security.enterprise_roots.enabled

Observations from SailPoint Team Our colleagues from SailPoint have tested the setup in their environment, and according to them, it works as expected. However, their browser is not hardened, and they have leveraged the SailPoint UI for authentication instead of the built-in Firefox authentication prompt.

Further Investigation • Is there a specific configuration required in the user profile settings? • Network trace analysis shows 404 errors on GET requests and the following error codes on POST requests: • 302 Redirect: Mozilla Documentation • 408 Request Timeout: Mozilla Documentation

Next Steps Is there a specific security setting that needs to be enabled or disabled? Are there any particular Firefox enterprise policies we should modify? I have also attached screenshots for reference. Let me know if you need specific logs or network traces for further troubleshooting.

I am planning to buy a new computer to replace my current one. The new computer will have Windows 11 and the current one Windows 10. I notice the current Thunderbird files are located in C:\Users\(username)\AppData\Roaming\Thunderbird. I backup these files every day. When I install Thunderbird on the new computer, do I copy my backed up files to C:\Users\(username)\AppData\Roaming\Thunderbird BEFORE starting the Thunderbird application on my new computer for the first time? Will Thunderbird be able to locate all of my email accounts as well the current local files? Is there anything that I need to do and/or change? Thanks for your help.
