My page throws errors in Firefox Nightly such as

Expected color but found ‘undefined’. Error in parsing value for ‘background-color’. Declaration dropped. preview.htm:1:1

and

Expected color but found ‘undefined’. Error in parsing value for ‘color’. Declaration dropped. preview.htm:1:1

The page references ten CSS files besides having dozens of its own CSS declarations. The issue is tha the reference provided to the error (:1:1) does not indicate where I can find the error. That is, I don't know which declaration is at fault. Is there some straighforward way to find the declaration in question?

Hi guys,

My Firefox Nightly keeps asking me to download empty files with random names, e.g. ABC1234567.htm, they always have random letters and digits but the .htm extension is always the same. The files are always empty, 0 bytes. As far as I noticed, it happens when I navigate through pages, e.g. clicking on various buttons on sites or using the Back/Forward buttons on my mouse. I tried to lookup of what's the source of the files via F12->Network, but it did not show me anything related to this problem.

It happens on different websites even on the site coded by me, so that's definitely a browser/extension issue. I saw some posts mentioning this problem on Reddit but there were no solution/explanation.

Just now it asked me to download 3 different files in a row. I made a screenshot of this issue.

Firefox 103 Nightly, Win 10.

Hi, It is not a question but a bug report. From the version 131 up today the Nightly stopped to initialize quickly as before. Certainly, it is not the windows 10 21H2, the antivirus, the firewall or anything other similar internal problem, just because the Edge and the Opera are working fine and they are four times more rapid than the Nightly. It is just to say, that your procedures to improve the security is transforming the Firefox in a mirror of the usefulness Chrome. I take the time to open the home page of Firefox = 9 seconds, against 0.28 s of the Opera. So, I think you should rethink the security and other hidden setting options of the Nightly, because as is, it is very bad. The big thing that the Geeks from silicon Valley did not have in mind is: There are lot of people that need to find extremely fast a configuration, like to export/import passwords from older browsers, or computers, without need to replace one by one. There are many other things that you decided to hide, but I don't know why. Anyway, I will try to update one more time, then, unfortunately I could not use the Firefox anymore. Further, I want a few add-ons, either if there is any percentage of insecurity. A few times we need afford risks to understand and discovery other problems in the web. We cannot do it anymore with the Nightly.

Youtube seem to be having problems with video decoding, previous frames seem to be displayed from time to time. for ex, this video: https://www.youtube.com/watch?v=dFhzMEnCEhY

The same profile works on Firefox 134.0b8 (64-bit) without problems, but not on nightly. If I just disable `media.hardware-video-decoding.enabled` and restart, then the problem goes away on Nightly.

Enabling/Disabling my user customizations don't seem to affect it. Enabling/Disabling addons don't affect it. Using a new empty profile also doesn't affect it, the problem persists. I tried deleting "gmp-widevinecdm" folder and redownloading it, still didn't solve the problem.

I seems to be some sort of regression, it used to work before a couple of days ago. Please fix, I hope the information I provided helps, as I like having hardware acceleration.

I also tried to update the display driver. nVidia Driver: 31.0.15.5176 now 32.0.15.6636

Hi Team, I am using Linux Mint 20 Cinnamon. Cinnamon version is 4.6.6. The issue is that I was browsing and by mistake I selected one tab then dragged it for sometime and then released the tab but that created a new window and now the old windows are not visible in ALT + Tab function. The windows are showing in the Firefox task manager and also the box icon in the top right corner in that "open tabs". Now I am not able to even change the window or able to access the opened tabs. Attached the screenshot and as you can see in that there are total 4 windows showing in firefox and one as active but in the bottom on the firefox icon you can see its only 1 window. How can I access the remaining 3 windows? Found one ticket (https://support.mozilla.org/en-US/questions/1477845) in this the recommend solution does not work. When I try to click on the window 1 tabs then I do not get any response. I tried both the solution but none worked.

Thanks for the help in advance. @Mozilla team member is seeing please check and fix this bug if possible.

How to disable Enhanced Tracking Protection on all sites and for every FF session. Choosing Custom, and deselecting all check boxes doesn't work.

I have tried the suggestions as described in the following article: https://support.mozilla.org/bm/questions/1273784 However, am still having the issue. It's as if the settings are totally ignored. I am using version 108.0a1 of Firefox developer edition. Ideally what am trying to achieve is away to disable all features of ETP. I figured setting it to custom with all values unchecked would have done the trick but it's not working. What works is if I add the site to the list of Exceptions for Enhanced Tracking Protection, then I will see all Ads loaded just fine on the page. However, this is not viable for me as I have a large list of sites that I visit, and I need to see the ads on them.

Does anyone know of a way to get around this feature in FF?

Is there another setting am missing from the previous article?

Uncaught Out of Memory Error Despite Ample RAM Availability - Firefox 126.0a1

Hi,

I am encountering an issue where Firefox throws an "Uncaught out of memory" error in the console, despite my system having ample RAM available. Here are the details of the problem:

  • Error Message in Console: Uncaught out of memory
  • Memory Usage Observed: Using about:processes, I noticed that Firefox's maximum memory usage caps at around 7GB.
  • System Specifications: The machine running Firefox has 128GB of RAM, so there should be plenty of memory available.
  • Firefox Version: 126.0a1

Given the significant amount of RAM available on my machine, it seems unusual that Firefox would hit a memory limit at just 7GB. I suspect there might be a bug or a misconfiguration causing this issue.

Can you please assist in diagnosing and resolving this problem? Are there any settings or configurations I should adjust, or is this a known issue with the current version of Firefox?

Thank you for your help.

I really do not like the new menu / toolbar in firefox nightly. I guess I hadn't really noticed the changes until now. But it takes up half the page of my browser. Who thought this was a good idea? - to put it smack dab in the middle of the page?! Not me, that is for sure! Ok. So can we see a normal toolbar/ menu bar/ and optional toolbar at the top of the page, please? I like things the way they were. With various options to add buttons and pages or things that we need?? My toolbars were stacked appropriately in roles, with everything I needed on them. And they were always in the same place. Not moving around like toys on the floor. Please, please bring back the old toolbars for this old cranky punk chick. Thanks!! Love Firefox, stop messing with it. 💗💗💗😸😸

I seem only to have issues installing the Nightly build. I have successfully installed Firefox's main, beta, and dev builds.

I received the following error/message when installing it. (see attached images)

This issue occurred on a fresh install of Windows 10 directly from Microsoft's image creation tool. I upgraded to Windows 11 and experienced the same behavior. I used the tool Revo Uninstaller to uninstall previous versions of FF completely and used the tool to clean and purge any leftover registry entries and directories. No errors or entries in Event viewer.

Anybody run into this issue?
