Firefox Support Forum

We have a noticed a very strange behaviour with the latest FireFox (126). One of our webpage is behaving differently across our Integration and production environment. Both env are running identical code and similar network stack the only difference we have noticed so far is for our Integration env Firefox is sending the different user-agent string than for production.

Steps to reproduce: 1. Open https://integration4-view.publitas.com/automation-int4/reader-happy-path/page/1

2. Go to console and view navigator.userAgent the user-agent string will be:

    "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:126.0) Gecko/20100101 Firefox/126.0" 

3. Now open the same content on production -> https://view.publitas.com/automation-prod/reader-happy-path/page/1

4. Go to console and view navigator.userAgent the user-agent string will be:

   "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) FxQuantum/126.0 AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.5060.71 Safari/537.36" 

Our website changes behaviour based on which browser it is and based on second string our backend interprets the browser as chrome instead of Firefox.

If I change privacy.resistFingerprinting to True then the user-agent string is sent correctly.

Can you please help us identify what changed in the latest version that is causing this behaviour.

Version: 126 (64 bit) Test on Windows 11 and Mac OSX

YouTube content doesn't load. Same with NYTimes.com articles.

Up to date, no extensions, no add-ons.

Running Sonoma 14.4.1

Safari and Chrome work as expected.

I was browsing a webpage that turned out to be in Portuguese, and I was looking for how to translate it, but the internet indicated that Firefox has built in transation! However, neither the Translate Toolbar Icon nor the Translate menu option appear, even if I visit a site that absolutely should be translatable (https://fr.wikipedia.org/wiki/Mozilla_Firefox)

Additionally, if I go to Settings -> General, there is a Translations section, but if I click the Settings button, there are no languages in any of the boxes and no option to add any.

I am on Firefox 126.0 for Windows.

Here are the things I have tried:

• Restarting Firefox
• Rebooting my PC
• Disabling all my extensions
• Running Firefox in Troubleshooting Mode
• Clearing my Startup Cache
• Performing a "Refresh Firefox"
• Toggling and Untoggling browser.translations.enable and browser.translations.automaticallyPopup

Does anyone have any suggestions of something I could have missed?

Hi,

The Lower Toolbar is quite handy, with for example Roboform.

Unfortunately, the way it's implemented, it comes above the lower part of the browser window, instead of being inserted at the bottom while the browser windows height is reduced.

That hides the search box when you type Control-F.

It would be nice if this could be addressed in a future release. I am using Firefox Developer 127.0b2.

I have enabled my new Theme but it keeps defaulting back to my old Theme. I have tried closing Firefox and opening new tabs. Opening a new tab also changes it back to the default theme. I have sent an image of the old theme. The new theme is Aurora Australis. And the second image shows this Theme enabled. What gives? Carl

Running Firefox 126.0, which Firefox' About link says is current. Dell laptop running (current) Win10 Pro.

As recently as last Wednesday (15 May 24), everything was normal. Since yesterday (16 May), on the Wall Street Journal site, after I have logged in, I no longer have access to articles' comment threads. The Show Conversation button shows 0 comments (which is erroneous), and when I click the button, it changes to Hide Conversation (which is normal), but nothing else happens--just white space and no comments or comment text entry field.

On Fox News, the comment thread doesn't display, and there's not even displayed a link to a comment thread. Until yesterday, the thread normally displayed, but required login to comment. Since yesterday, logging in changes nothing: the comment thread still doesn't display at all.

On X (nee Twitter), when I click the login icon, I get the usual login box--but it's solid black with only a rotating arrow signifying "loading." It never finishes loading. An added fillip: X, as recently as last Wednesday, displayed in its usual black text on a white background. Now it displays as white text on a black background. I can click on X links sent to me and get that particular X post to display, but I cannot log in.

When I go to those sites in Edge, everything behaves normally: I have access to comment threads, and I can log in to X. One exception: X displays as white text on a black background on Edge, also. This doesn't seem to be an X thing, though; on my wife's laptop (Firefox 126.0), running WIn11Pro, her X display is the "normal" black text on white background.

I haven't changed any settings in Firefox. I do have a couple of ad blockers, and I've turned those off, one at a time and both together; that had no effect.

How can I get things back to normal in Firefox?

Thanks

The blinking screen is on ebay but it just keeps on blinking. I have tried other programs and it only happens with this one and only with ebay. This is the new tab stuff: https://www.ebay.com/itm/401568771184?_trkparms=amclksrc%3DITM%26aid%3D777008%26algo%3DPERSONAL.TOPIC%26ao%3D1%26asc%3D265563%26meid%3D7245a46a376945799ec6d6e8ae3176fa%26pid%3D101967%26rk%3D1%26rkt%3D1%26itm%3D401568771184%26pmt%3D1%26noa%3D1%26pg%3D4375194%26algv%3DPersonalizedTopicsV2WithDynamicSizeRanker%26brand%3DFintie&_trksid=p4375194.c101967.m162920&_trkparms=parentrq%3A88a4a82d18f0ad8bbb523870fffffa70%7Cpageci%3Ab38440d1-149b-11ef-b242-1adf3ab78462%7Ciid%3A1%7Cvlpname%3Avlp_homepage&afsrc=1&mkevt=1&showcs=1

Thoughts?

For some reason, the bullets used to hide a password are not rendered properly in Firefox. As shown by the first uploaded image, they are displayed as big white-filled circles.

This problem does not occur on chromium-based browsers, as shown by the second uploaded image, which is a screenshot taken from chromium, on the exact same session.

I have already done the following:

• verified that the "Allow pages to choose their own fonts, instead of your selections above" box is checked in my preferences. I have also tried disabling and re-enabling this option
• launched FF in troubleshoot mode to disable extensions and hardware acceleration
• verified that gfx.downloadable_fonts.enabled is set true in my about:config

All of these attempts however failed to solve the problem.

This problem is occurring on a fresh install of a Linux distro, so I first thought that I might be missing some fonts, but the problem might lie somewhere else since the symbols are properly displayed in chromium-based browsers.

I'm running Windows 10, Firefox Release 126. I had the same issue with the previous version of Firefox. I was hoping 126, would fix the Chase Bank issue.. But it did not I read several articles from FF users, I checked my User Agent Settings, they are correct. Called Chase, they said use Chrome as Firefox does not have the 'needed code' to work with Firefox. Been using Firefox with Chase for at least 5 years.

Please help, Thank you

I have used a free Hit Counter for many years that I got from https://www.freecounterstat.com/

I have 3 such counters and have stopped working in the latest version of Firefox on my desktop. They work with Firefox on my iPad and Android phone. They also work fine if I use the Edge Browser but I prefer using Firefox as I have for many years.

The embedded code is pretty simple, here it is for one of my counters... <a href="https://www.freecounterstat.com" title="visitor counter"></a> Can you help? Thanks, Bill T

Trying to recover from a hard drive crash. Had to buy a new desktop with Windows 11 Pro (looking to be a bad move). I downloaded/updated to Firefox 126.0 (maybe also looking to be a bad move).

Have my last "working" userChrome file (it took me weeks to perfect this to my needs).

I am looking for: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

but there is no "AppData" folder. And there is no existing userChrome.css file, anywhere!

Is the functionality I am looking for a thing of the past?

Is Firefox not completely supported by Windows 11?

If so, what is the last version of Firefox that will still support userChrome.css?

I'm using bandlab to link me and my friends who are hundreds of miles away to make music. Firefox and all browsers crash a lot with a "high memory usage" alert. But these are pretty big projects. I have 32GB RAM, this thing is crashing at much lower RAM levels than I would like for it to use. like 1GB seems to be the limit (i dont know that number if its exact or correct)

Is there any setting where I can INCREASE memory usage so I dont lose work from random crashes due to memory usage?

When I click on "Bookmark current tab," the small bookmark window opens as usual. But if I then click on "save," nothing happens. The bookmark does not get saved anywhere and the window does not close. Likewise, if I click on "cancel," nothing happens and the window also stays open. Only if I click somewhere outside of the bookmark window does the bookmark get saved and the window close. This has happened only in the current and previous version of Firefox. How can I fix this?

It takes a lot longer than it should to load my home page, MSN. This problem is more pronounced with Firefox than other browsers. What can be done to load the home page faster? And, in general to load websites? Can someone help? Thank you.

My firefox disappeared after i found out someone using Windows 7 used my hotmail account address.I dont know how to rectify this and get my firefox back and change my email address with both Mozilla and Microsoft Outlook

This has been a problem for a while, currently on Firefox 126.0 and Nvidia 550.78. I can work around the problem by forcing webrender to use software mode.

When using HW accelerated webrender with my Nvidia graphics card everything works fine until the PC wakes from sleep, then graphics are broken and Firefox needs restarting. Most noticeable for me is when looking at Grafana graphs they will look like random lines, and my Frigate NVR snapshots only display some of the time.

Is there anywhere in Firefox that will show a log of any error messages to do with the graphics card? I would like to try and fix the problem rather than disabling HW acceleration, but with no logs to look at that is impossible. No other programs seem to have a problem with resuming from sleep, and no error messages are shown in any of the system logs.

I hve discussede the matter with my banks IT-department, but they answer me that recently they have heard about the same problem concerning Firefox login and said that the problem have to be fixed by Mozilla/Firefox

Whenever I use the picture in picture feature, it always opens up in a bigger tab instead of the floating PiP. I am unable to adjust the sizing whatsoever. Is there a way to get around that?
