Today I Receive Mozilla Firefox 133(64Bit) Update. After Successful Update. My Open Tabs Are Not Loading. Also, Firefox Become Very Slow When I Surf Youtube Videos. Video Stuck But I Can Hear Audio. Taking Time To Load Videos. Its A Portable Version.

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

Hi,

I have been having this issue with Firefow & Youtube for some weeks now.

What happens is that I launch a video, it plays well, but after 1 minute it stops. No buffering, no download of the next chunk of the video, nothing. It just stops. I have disabled all the addons I use and it changes nothing; in some cases, it stops the video from launching.

> Why this is not network related : on the same computer, at the same time, I can watch YT videos on Opera. Without issues. With uBlock origin enabled. And VPN. > Why I believe this is browser (ie. not computer) related : I have another computer, on the same network, that has the exact same issue. With less extensions, and no VPN. And again, when using Opera, YT works as intended, with uBlock origin.

There might be a setting related to video buffering to change, or something, I do not know. But this is beginning to be infuriating.

Is this a Google' crackdown on browsers not beging Chrome? Or am I an isolated case?

Thanks in advance !

When I try to open my LastPass vault: https://lastpass.com/vault/ The "LastPass •••|" logo is displayed, but nothing further happens.

This page is being loaded correctly by Safari and by Google Chrome.

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 did a search to try and fix this. Suggestions included, checking if Private Windows are on, Customizing Toolbar, making sure all extensions are enabled and Refresh Firefox, all of which I did with no results. Before I go nuclear and uninstall/install Firefox, are there any other suggestions to solve this issue?

I accidentally activated 'block element' for my homepage 'www.msn.com'. Now the site comes up blank. How do I reverse the 'block element?

I get this when I click through on an email from AliExpress... It's not the link as It works (Copy & Paste) in both Chrome & Edge.

The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

Hi, my session with a lot of open tabs has been lost due to a crash. In the profile folder, the recovery and previous files in the sessionstore-backups have been deleted. I tried to recover them using shadow explorer, but these files are corrupted, so I've had no success reading them. Is there a way to fix the corrupted files? Alternatively, because I've had sync enabled for open tabs, is there a log for past open tab synchronizations? If this was stored on the cloud, it may be possible to retrieve that table and restore the list of open tabs that way?

Google Drive says i am offline when i am not. Can move around the site, and it works fine on chrome, but not on firefox. Can also acces sheets just fine, and acces some files through there

tried contacting google, but since it was a firefox specific problem they could not help

On some websites, namely GMX, the UK Guardian newspaper, Etsy and PatientAccess (there may be others), I cannot sign in using my login details. If I switch to Edge, using the same details, with the same laptop, my login works immediately. This also happens with a second laptop. I have tried clearing cache and cookies, but to no avail. Is there any setting I can change to allow me to sign in or do you have to fix your browser.

The version of Firefox is 133.0. Since installation, I have not changed any Firefox settings.

Best regards

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)

I am using VPN and have excluded FF using split tunnel, so I enabled Secure DNS in FF with Cloudflare. When I first launch FF, I get a blank page and nothing in the address bar. After that, I can open all webpages just fine. It's only that first page right when launching FF that doesn't work properly.

I tried in another browser and Google Drive is online. Not on Firefox since the latest update.

Thanks in advance for any tip to troubleshoot. Internet connection is checked and okay. All the other google products are functioning as expected.

It certainly appears they have, with the left and right padding growing wider. In fact, they both look about twice the size of the top and bottom padding, whereas before I remember them as being about equal. The change was immediately apparent with my home page!

Any particular reason for this?

YouTube only on Firefox has terrible stutter/frame pacing issues, most prevalent when watching 4k/60 content. "Stats for nerds" shows a healthy buffer and minimal dropped frames. This issue is not present when watching local videos or on Microsoft Edge. The issue can be alleviated by watching in 1080p60 but stutter/judder is still present. The issue is not resolved no matter what power or performance options I choose in my laptop's settings. Any help is super appreciated, as I really don't want to open Edge every time I need to use YouTube. Thanks!

When I try and use canvas (https://canvas.oregonstate.edu/) the website is unusable. I tried clearing my history, and cache, but that didn't help much. This started after my Firefox updated

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.

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
