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?

Nightly updated this morning and the help menu from the sandwich has stopped working. The menu options display, but none of them function. Mouse click makes the menu disappear as if it's going to show the panel attached to the option.

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.

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 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?

Browser is FF Nightly 112.0a, but this is probably a bug in stable FF, too. "Always ask you where to save files" is checked, in preferences. Like title says, the "last download location" is stored, and works for downloading files, and downloading a SINGLE item in Tools\Page Info\Media (Ctrl-I), but if multiple items are selected (in Page Info\Media), folder opened will always default to set location, instead of last download folder.

I am currently on 133.0a1 (2024-10-04) (64-bit) Nightly and the new tab button to the right of the tabs is missing. It will show up sometimes, but I have to go to customize and move some things around, then start browsing and it will pop back up.

I use that button often, how do I get that back?

Hi, so I've "Show an image preview when you hover on a tab" setting under Tabs section "Off". Preview is not showing but instead there is am empty box like on attached image. I couldn't find any other option to turn that off also.

I'm using latest firefox nightly release.

Just now I recreated my firefox login password and re-logged into the firefox account. After synchronization, I did not find my bookmarks and saved logins. Could you please help me troubleshoot the problem? Firefox Verison: Desktop: Firefox 102.9.0esr(64Bit) Debian 11 Mobile: Firefox Nightly 113.0a1(Build #2015940355), 77b44afdeb+ GV:113.0a1-20230322094136 AS:97.2.0 Android 13

I never feel like webpages scale properly when I visit them. There is always content left off screen or I have to zoom out so much that the text is too small to read. Is there a setting I can change to affect this?

This webpage is particularly egregious: https://www.desktopmetal.com/products/shop

My Firefox Nightly version is: 135.0a1 (2024-11-26) (aarch64). My computer is a: MacBook Air (15-inch, M2, 2023) running macOS Sequoia (Version 15.1). I have been having these issues for a long time regardless of computer.

I have attached a picture of the labs settings I have enabled but I cannot see why any of them would affect this.
