I haven't upgraded browser versions for a while and I'm now going from 109 to 132. Pretty bad I know.

I'm having a number of issues but for this post I'd like to concentrate on userChrome.css.

In version 109, I had a custom font for the top menu bar, the top menus, the bookmark toolbar, the bookmark toolbar menus, and the right click menus. I did this by including the following in userChrome.css (as per [https://support.mozilla.org/si/questi.../1335097|here]:

1. navigator-toolbox { font-family:"MyFont" !important }

This worked great, but it is no longer working in version 132. Obviously I don't know in which Firefox version this stopped working.

Has this been disabled by Mozilla or has it been changed? If it's been changed, how can I achieve it now?

I'm very grateful for any help!

Several weeks ago, I was attempting to upgrade from Windows 10 to Windows 11. In the process, I deleted Firefox (using Revo Uninstaller) and then reinstalled it, downloading it from the Mozilla website. Unfortunately, it didn’t run, giving me, at different attempts, different error messages. In the time since then, I have read many suggestions from many different websites and I have tried some of these suggestions, all with no success – until today. I have just completed the suggestions made on https://support.mozilla.org/en-US/questions/1327628 and Firefox is now back, working. I am happy and grateful, but not finished. None of my personal data came with the currently functioning version of Firefox. Since the re-emergence of Firefox, I have been reading several websites dealing with copy, backup and restore of my Firefox profile. Right now, the path C:\Users\rsuth\AppData\Roaming\Mozilla\Firefox\Profiles\ shows 5 folders: Two of the folders show 11/11/24 as the date modified (probably the date of the download from Mozilla). The folder 0dppjrfa.default contains one file, times.json, dated 8/11/2020. The other folder, ru82tlj5.default-release, has 97 items, most dated 11/11/2024. The remaining three folders are all dated 12/2/24 (today, as I write this). One folder’s name ends .default, the second name ends .default-release, and the third name ends .default-release-thirteen digits. The question that I am asking here is what do I do next to, hopefully, bring back the personal date I had with Firefox before my updating to Windows 11. Should I delete the folders dated 12/2/24? What, if anything, is the significance of the folder whose name ends in 13 digits? I’m hoping someone will be able to tell me how to fix these Firefox problems. And if I can, then I hope to be able to do something similar to help me bring back Thunderbird as well. Thunderbird became unfunctioning at the same time as Firefox. Thank you.

I am writing to request assistance with my Mozilla account. I am unable to access my account due to several reasons: I have lost access to the two-factor authentication app, I have lost the backup data with the 10-digit recovery key, and I no longer have any devices where I was previously logged in. I only have access to my email address.

I do not need access to the synchronized data; it would be acceptable if you delete it and allow me to register a new Mozilla account with my existing email address. Using a different email address is not an option for me.

I am in the process of transitioning away from the Google ecosystem and would like to use Mozilla's services and products. Could you please help me reset my Mozilla account so that I can register a new one with my current email address?

Thank you for your prompt attention to this matter.

Best regards, Evgeny

My YouTube homepage is blank when I visit using Firefox (see attached screenshot). Here is a list of all of the fixes I have tried:

-Disabling all extensions and turning off Enhanced Tracking Protection (at the same time) -Clearing cache -Clicking 'forget this site' on YouTube in my browser history -Restarting my PC/Firefox -Refreshing Firefox profile (this worked, but the issue returned after an hour) -Changing my system theme to light mode -Launching Firefox in troubleshoot mode -Logging in on an incognito window (with the same result) -Probably some other things I'm missing (I tried pretty much every result I could find from looking up 'YouTube homepage is blank' and 'YouTube homepage not loading).

The issue only occurs on Firefox and only after I log in to YouTube. This has never occurred before. I checked to make sure my Firefox and YouTube settings are the same as they've always been.

YouTube videos load fine as long as I paste the direct link into the URL bar, but ONLY the video (no comments, recommended videos, likes/dislikes, description, etc...) and I can't take it out of theatre mode nor fullscreen it (fullscreening it just removes the top bar of the browser--the video itself still has black bars on the sides).

Sometimes when I reload the page, I see the following at the end of the URL: &ThemeRefresh=1. I don't know if that means anything.

I am using the Firefox app on Windows 11. I am not using a VPN. This issue is specific to YouTube and YouTube only.

Any help would be greatly appreciated. Thanks!

I was excited to receive the new Tab Groups feature and am now disappointed that it's not working and I've 'lost' dozens of tabs.

Here's what I did: I created several groups by right-clicking and added tabs to each of the groups. Since it appears that only way to collapse a group is to "save and close group," I closed each group. Now they are all gone. When I right-click to create a new group or "add tab to group," the closed groups are nowhere to be found. Plus, I do not see a "list all tabs icon" on my toolbar to reopen the grouped tabs, which is what [article] says should happen.

Suggestions for making this work?

Hello,

Moving from an older Ubuntu 18.04 machine where Firefox is limited to version 113 to a newer machine running Mint 22 where the current version is 134.

I know how to transfer the profiles but I could not find any information on compatibility.

Would I need to install other versions before 134 to handle any changes?

Thank you

I'm having much difficulty in attaching a article I see to Facebook. Its possible the problem may be I'm not using the right instruction on the Firefox options when I right click the article I want to attach to Facebook. Some of those options are, Save link as, Copy link, when I right click for options. Can someone explain what is the right option to use? And, how do I proceed once I choose the correct option to make that attachment to a Facebook message I'm replying to? There are times a picture of the article will attach to the Facebook message, but the text that is associated with the attachment will not appear? Can someone please help? Thank you.

The camera won't turn on in the Firefox browser for Google Meet or Zoom. It says it can't find the camera or that it's turned off. I have checked my Windows 11 settings and desktop apps have access to the camera. I have also checked the settings for each of the sites and use of the camera and microphone are allowed. Autoplay is enabled too. The camera works fine in other apps and in other browsers.

With reference to my question just posted, also now when I click on my Firefox browser, the Yahoo search engine seems to take over and it won't let me come out of it. Mark

Not sure whats going on here, been using FF for decades with no problems. I am saving bookmarks to various folders but recently noticed some were not in the folders I was sure I had saved them too. For example, in the screenshot attached I had saved the Rink Diary Bookings to my Bowls folder, but when I opened the folder later the bookmark was not shown. I did the Google search and checked what I could and most solution options were aimed at the Toolbar, which I didn't have a problem with. I then noticed some other bookmarks were no longer showing. I then saved a new Rink Diary Bookings link (now ending in '1') to a second folder so I knew which link was from each folder. This new bookmark also failed to show in the new folder. I somehow found a search button for the bookmarks and found both the bookmarks in the correct folders. (See attached) Can anyone advise how to get the bookmarks to show in, and open from, the actual folders? I am not very tech minded so any help is appreciated. I have copied the folder menu's in the attachment Thank you.

i recently disabled 2fa and installed a new authentication app: Ente Auth. i keep getting invalid code each time i enter the generated code. i tried both options, scanned the QR code and entered the secret key manually. i used authy with success as my auth. app with firefox but can't use authy anymore. keep having issues setting up 2fa with other auth apps. thanks for any help you can offer. peace, Adrian

Since the 132.02 certain eBay items will not display its shipping info. Only on Firefox. Its not addon because I disabled all and I have the same addons installed on edge and all good there, I can see the shipping info on edge. And its only about 50% of the items which is weird. I have done the basic troubleshooting and I have to think it was this update. If you see the images attached Shipping values should be displayed. Some have a $ value some say +shipping, those are not displaying the value. Please help me figure this out as I use Firefox ALL day but if this continues I HAVE to switch. Ebay is my main source of income now.

Since the update I've had a few issues, most I was able to fix but this one eludes me. Opening up various news sites I get the "Firefox prevented this page from reloading" error at the top and clicking allow does nothing. Anyone know how to get around this error? I'm not looking to totally disable the FF feature that prevents other pages from loading a different one, but just to browse the website after hitting 'allow'.

Thanks in advance.

Went into Firefox and got the error message: Platform version 131.03 is not compatible with min version>=131.02 & max version>=131.02 So I'm thinking that the last update caused the error. I did a system restore to a week earlier, and after 5 hours, the computer rebooted to that date. Upon opening Firefox, I found the the notice that the next time Firefox opens, it will update. After closing, and reopening, Firefox updated and displayed the same error message. Nor quite sure what to do, I downloaded Firefox again, and was going to uninstall and reinstall. But as soon as the download finished, it loaded. So now I have the new Firefox without all of my saved bookmarks and passwords. I thought I'd read someplace that that wouldn't happen, and all of my password and bookmark history would transfer to the new Firefox. As if that wasn't enough to ruin my day, I found that the new Firefox isn't working in my wife's account on the same computer. She gets the same error message as I did before the new install. I know, my fault for not backing up the bookmark and password files, but what's my option now?

I know that typically mozilla does not put a low bound on advisories, and https://www.mozilla.org/en-US/security/advisories/mfsa2024-40/ is the advisory for vulnerabilities fixed in ESR 128.2. CVE-2024-8387 is listed here. yet the advisory for 115, https://www.mozilla.org/en-US/security/advisories/mfsa2024-41/ does not list this vulnerability. Was this something that was only impacting 128 (for the ESR builds) or is there a mistake that either 115.15 did patch it but it wasn't documented, or the patch has been missed and ESR 115 is still vulnerable?

When I open up the Add-ons Manager it shows Window Titler is turned on. But Ctrl-Alt-T no longer works, there is no button showing for it, and it seems to be gone. A button for it does not appear in Customize Toolbar. It is the single most important reason I stay with Firefox. How do I get it to work again? Thoughts appreciated.

When loading webpages, it will often take 60-90 seconds to load the page. I've only seen this happen when loading the page for the first time, once it loads navigating through subpages is seamless. It doesn't seem to be tied to any particular domain, I've had it happen randomly on gaming websites, tech websites, even google searches. The most notable coincidence is that in the networking tab of the developer console, it always(?) takes almost exactly 30 seconds on DNS resolution, 30 seconds on Connecting, sometimes a 30s Blocking element, and then the remainder is near instantaneous; screenshot attached. My network is fine, I'm able to play low-latency games without issue, and Chrome is not exhibiting the same behaviour.

Things I've tried to resolve:

• Restarting computer -- issue has been persisting for months
• Created a new Firefox profile -- still showing the same behaviour
• Disabling all addons/testing Troubleshoot Mode
• Proxy settings in Firefox -- No Proxy and System proxy settings are both showing the behaviour
• Disabling DNS over HTTPS

Any help would be greatly appreciated.

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

The security sequence for log-in is supply of user-id and then password; that works fine; then a send unique code dialogue pops up and it leads to an error screen which I am attaching. I have rung the number provided and they say they don't support Firefox; so that looks like end of Firefox use to me and goodbye (can't find a tearful emoji to insert).

Gotta say this kind of thing is happening quite frequently for me; mostly without a nice error screen like this one; last one I recall was hunting for car insurance; on the screen where it listed the billions of quotes to eager providers none of the links to click through for the quotes worked... and with this happeneing more frequently now you go... ohh it's firefox again isn't it... so you reluctantly fire up Google Chrome and of course it works OK.

So I'm kinda here with a broader outlook than just this specific problem; I really am on the verge of giving up with Firefox; it should just work shouldn't it; and it increasingly doesn't anymore; I don't want to get into an extended and convoluted dialogue to help you cure this issue; I'm simply perplexed that some really basic stuff doesn't work anymore; however; I've used Firefox for centuries so thought I should give you at least a chance so I could declare how I feel etc.

I am up for a dialogue over this and hoping this is an easy fix; but; as I say; I'm confused as to why, for me, Firefox just simply doesn't work well anymore; it just should and I shouldn't be here.

This morning I went to check my email on gmail, and google asked me to sign in again. Easy, I thought. I entered my account, and then google asked for my passkey. Until this morning this meant that on my mac it would ask me to place my finger on the right key on the keyboard. This morning it just froze firefox indefinitely. I then tried on Safari, and it worked as expected. I checked the version of firefox: it's 136.0.1. Obviously something changed (i.e. broke!) with the new version. Has anybody else experienced this? Any suggested fixes?
