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?

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.

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

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/
4. https://opensource.org/

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.

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.

My extensions are not showing up in the firefox browser, on menu bar, tool bar, or bookmarks bar. I am elderly and NOT computer literate. What to do? Using Windows 10.

Thank you.

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

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.

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!

I need to prevent the spacebar from scrolling while I am in Firefox. It drives me demented! Every time I lean forward to concentrate, my clothes accidentally brush the spacebar and it sets off a superfast scroll, which gives me a severe shock and loses my place. Help me deactivate that function please. Surely, it must be optional?

In case you're wondering, yes, I do push the keyboard away when I read, but then I bring it forward to take a note in a Word document, and by that time I am so absorbed I don't notice whether or not I've pushed it away again. I have tried to create the habit but can only do it when I start to read, and never when I return to read. The shock and discombolulation physically hurts. Help, please!
