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?

Yahoo isn't loading at all for me, more specifically guce.yahoo.com. I have managed to get into the login.yahoo.com page and log in but after the log in process it goes to the first page again and gives me the same "The connection has timed out". I just installed the browser and this might make me not use it ngl. I have tried both clearing cookies and troubleshooting mode.

The first image speaks for itself. When I want to change the way this setting is set in a Facebook group, when Firefox is full screen, the associated dialog is so placed and/or sized on the screen that it is partially truncated on the left by the left side of the display. I just checked in MS Edge and it displays normally there with full screen display. It displays normally in Firefox when I Restore Down. So this one at least does seem to be specific to Firefox.

I have a second full screen display issue that may be related, but this one isn't just Firefox; Ms Edge also shows it, and other applications also behave similarly: the right hand scroll bar disappears in full screen (as does the applicaion menu control)! I had some trouble taking a pair of images to illustrate this, using Snipping Tool. The second image, when Firefox is set to restore Down, shows the scroll bar and application menu control, which is what I see. The third image was more tricky to take because the first time I tried, the screen capture included a scroll bar and application menu control even though they were not visible on screen. I had to redo it and be very careful not to let the right hand side of the selection drift off the right hand side of the display.

It seems like the full screen display is just a little "larger" than the physical display. I have tried one or two other screen resolution settings and that has not helped. My best guess is that it's a monitor settings problem, but I've also fiddled with the monitor settings, again with no success. And even if a monitor setting explains the pervasive right hand side issue, it doesn't explain the Facebook dialogue issue, which does appear to be Firefox-specific.

So my current workaround is just not to have anything full screen :(

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.

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.

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

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.

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

1. https://kdice.com/
2. https://latinitium.com/
3. https://theysaidso.com/

I've noticed since a few upgraded of Firefox tat I am having an issue loading my local uTorrent GUI at: https://192.168.0.xxx:36724/gui/index.html. I am currently using 132.0.2 x64 and it eventually loads after 3-4 minutes. There are absolutely zero add-ons at the moment, and it does not matter if it is a portable version or standard installed version. I do not seem to have this issue while using Firefox (latest) ESR portable version.

Is there something I'm missing here? I am not sure if it is the port that's the issue with Firefox, because I have a local website using port 9090 and 8080 without any issues on loading. Also, it is happening with the nightly version of FF as well. All other browsers load quickly.

Kind regards,

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.

After watching this video https://www.youtube.com/watch?v=mAfY_bNJTBI i went to https://www.cloudflare.com/ssl/encrypted-sni/ and did the test. Result is 3/4. (See screenshot below) Secure DNS, check DNSSEC, check TLS 1.3 check Enrypted SNI, fail In Firefox i tried doing exactly what the person did in the video but i dont have the settings he is showing in about:config Why is that? (Below you can see the screenshot, those settings are missing from about:config)

So my question reamins simple, how can i enable Enrypted SNI in Firefox?

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?

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.

Dear Firefox

I am writing to you as regards your current upgrade and its interface. The taps bar and tools bar are very wide, thus decreasing area below them. The cannot because customized with the little knowledge I have in development.

I jumped FF V90 to this current upgrade FF 131.03 because anytime I tried to upgrade, I find the Interface not to my liking due to what I have already described above. I have seen similar comments like mine on the browser comments. One user actually asked if FF interface to V 80.02 which I support for it is the best of Interfaces so far in the development of the FF browser.

I hope to hear from you soon before I take a decision to go back to FF V90.0.

P/S: My 2 email addresses:

                                            1. [edited from public] @AOL.COM
                                            2. [edited from public] @GMAIL.COM

Also in trying to upload Image of the browser for clarity purpose, I get this:

                                           Error uploading Image
                                           Invalid or no image received.

What is happening here about Uploaded images: Add images (optional), I cannot fathom. There is certainly a block somewhere on the Support page.

Kind regards.

Yesterday, I get a screen popup that says" Outlook(formerly Hotmail)" Saying Hotmail will now be Outlook.

I've had Hotmail for maybe 30+ years now? I've always had Firefox open to my inbox, which is Outlook and has been for a year or better.

Since yesterday it will not open up to my inbox. It opens to the MS website showing what I wrote up above and a picture of Outlook.

I've deleted cookies and cache. Also history. Even though I point it to my inbox it just goes to that advertisement. I have the stay signed in box checked and don't show this again. But it does show again and again. I hope there's a way to fix this, pretty sure it not a Firefox issue. Just hoping someone else has had and and found a way around it.

Thanks Daniel B
