A friendly hello to whomever is kind enough to read this! Your help is greatly appreciated!

The latest update caused an edit I made to my Profile's userChrome.css file to be nullified. Now there's huge bar where the tabs toolbar used to be, and apparently it's not the title bar, as when I activate the title bar in "Customize Toolbar," this huge gets replaced by the actual toolbar.

I've attached my css code below for inspection. It used to work perfectly, but after the last update (133.0) it's no longer working. What can I do to fix this and have it like I had it prior to the latest update (133.0)?

userChrome.css File: `#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

}

1. main-window:not([tabsintitlebar="true"]) #TabsToolbar {

   visibility: collapse !important;

}

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

/* Adding empty space for buttons */

1. nav-bar {

margin-right:140px; }

/* 15px for dragging whole window by mouse*/

1. titlebar {

appearance: none !important; height: 15px; }

/* Fix for main menu calling by Alt button */

1. titlebar > #toolbar-menubar {

margin-top: 10px; }

/* Move minimize/restore/close buttons to empty space */

1. TabsToolbar > .titlebar-buttonbox-container {

display: block; position: absolute; top: 17px; right: 1px; }

1. sidebar-box {

 min-width: 250px !important;

}`

This has been a problem for me for a very long time, and I'm tired of having to use Chrome every time there's an update to Firefox.

The issue I have is that I will get the notification saying there's an update. I click the button to update now, the browser opens the auto download page and I get a not secure connection warning. The only work around I've found is to use Chrome, and sometimes I can use the "Other downloads" option.

I'm not running a VPN, or any other networking software on my pc. This is for the full program, not the Windows Store app.

Secure Connection Failed

Firefox consumes almost 2Gb of RAM with only one tab open. I find this surprising, and it's a major performance issue for me.

Do you have an explanation or solutions to reduce this memory overconsumption?

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/

Recently, I am unable to open PDF's on Firefox. When I go to another browser and access the same site (such as a bank) I am able to view the PDF. I have tried some of the suggestions regarding extensions etc, but nothing seems to work. Is there a solution? Thanks, SVS

Suddenly Firefox is downloading my downloads to google drive. Why? I want them in my download directory, but changing the options in Settings/General/Download makes no difference. It is set to ask where a file should go, but does not. It is set to ask whether to open or save a file and it does not!

How can I get google drive out of this and save them to my desktop again?

Paypal hangs when transferred from vendor site to complete purchase. Relaunching Firefox in troubleshooting mode resolves issue. Also works with Safari. What's wrong, what needs to be changed?

Hello,

Usually both of my previously closed windows reopen without issue, but the data for both of them disappeared this time when I clicked on a zoom link after closing them. The link opened, but they didn't. I did the basic troubleshooting like checking my entire history (under "managed history") and looking in settings as well as following the instructions I found here at https://support.mozilla.org/en-US/questions/1407584, but everything's gone. It's like they never existed in the first place. Has anyone else had this issue?

Also, about a couple of months ago, Firefox started forgetting my accounts and logging me out of them once I closed the window/the tabs reloaded. Not sure if this is due to my computer's own storage (RAM) or an update-related issue - I haven't been able to figure it out yet.

Any insight on either or both of these is greatly appreciated!

When using website at https://tools.myfooddata.com/nutrition-facts/170112/100g/1 , the search box titled "Search for A Food" shows up in Google Chrome, but not in Firefox. In Google Chrome, it can be seen in the upper left part of the web page, but I can't find it in Firefox. Also, when I click on the button called "Instructions" on the web page, nothing happens in Firefox, but when I click on that button in Chrome, it opens up an instructions menu. What can I do about these things?

I believe this problem began in 133. I've noticed that if FF is open for a few hours, it starts to develop a very noticeable input lag. For example, if I'm watching a YouTube video and hit an arrow key to advance the video, there will be a couple of seconds before the browser registers the key press. It behaves like a high CPU issue but I do not detect high CPU usage when this is happening. Restarting the browser resolves the issue for a few hours.

This is happening on Windows 11 as well as on a Mac running Sonoma.

Hi, my account seems to have some kind of admin or enterprise control on it, but I'm not part of an organization. It says:

Information Your browser is being managed by your organization.

I don't know how to fix this, but it is keeping me from updating and doing other things like clearing cache and adjusting my settings.

How can I fix this?

I don't know how it happened.

Thank you

I prefer to use Startpage as my search engine with Firefox on my Mac. I have that set up, but it's so annoying that when I put something in the address or search bar, no search happens. Instead, I just get the Startpage home page and then have to retype the same thing in there! How do I solve this?

Hi,

I installed Debian 12 on my laptop. I'm using Firefox 133.0.3 from Flatpak. When the browser is in full screen and I display a video in full screen mode, strangely, the video is not in full screen... It's on the top left corner and the rest of the page is in violet. I tested on different site, loading a local video and the issue is the same. I can't reproduce the issue on my desktop computer on Windows. When the browser is not in full screen (F11) and I put the video in full screen mode, there is no issue... I attached a screenshot of the situation.

Have you ever encountered this kind of issue? How to resolve it?

Thanks

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

When saving images from websites using the save image as feature, Firefox will freeze up and not register any mouse click or anything instead making a ding noise every time is register a mouse click. This will continue for like 30 seconds before it becomes normal then it will repeat this for every image. How can I solve this?

Hello

When attempting to pay for online purchases the new firefox upgrade (Mac 133.0.3) will not redirect from the merchant to the payment site. Yesterday, before the upgrade, was no problem making credit card purchases online; now, nothing. Please advise on how to set up new firefox version to allow redirect to payment websites from merchant sites.

Thank you.

I get bills in PDF form from my water and gas provider. When I pay the bills I use Adobe to add a "PAID" sticker and a comment indicating when the bill was paid, and then I save the PDF (from Adobe) with the newly added comment. Previously I was able to open these PDFs in Firefox and the contents of the comment (added via Adobe) was visible; however, recently when I used Adobe to add a comment to a PDF and then opened it in Firefox the contents of the comment were not displayed (NOTE: I opened the PDF in Edge and it displays the contents of the comment, but it doesn't display with the same wrapping as used when the comment was created in Adobe). Interestingly, older PDFs that I added comments to still open correctly in Firefox i.e. they display the contents of the comment. I am assuming there has been some sort of update to Adobe, and was wondering if there needs to be an update to Firefox to continue to allow the contents of comments in the PDF to be displayed.
