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?

When playing videos in various websites (Jellyfin, Mastodon, Youtube) hypridle is receiving many 'ScreenSaver inhibit' messages that are never cleared.

A similar topic pointed to dom.screenwakelock.enabled being the culprit and disabling that fixed that users issue. But I've done that and the problem persists (It did remove one extra lock, but that was the one that was getting cleared.

Chromium sets and clears 1 lock correctly.

System: NixOS unstable DE: Hyprland

I'm using `exec-once = hypridle >> ~/log.txxt` to monitor the logs.

This behaviour is new in the last few months.

It is only present on one of my two systems that is very similar, they both use the same nixos config. The one with the issue is a i5-4590S based system with no external GPU, the one that doesn't have the issue is a Ryzen 7 5800X3D with RX5500. But that may be a red herring, I don't always update the both at the same time, so they may have different software versions.

Hide some folders and then option to show all folders.

The folder section should have option to hide it and option to show all folders. etc. And also quicker link all profiles on the browser

Autofill Passwords intermittent. One time I go to login on to different websites and autofill works fine the next time nothing. It also seems like every time I open Firefox I have to check the autofill. I like FireFox and I'm trying to get away from another browser that I have no issues with when it comes to autofill. All I want to do is open a website autofill my passwords.

I recently added an entry to my hosts file but Firefox seems to ignore it. I'm using v. 128.5.1esr, fully updated. I've tried a lot of the advice online and none of it seems to work. Here's what I've tried:

disabled "Enable DNS over HTTPS Cleared the DNS Cache changed "Use system proxy settings" to "No proxy". tried troubleshooting mode set network.trr.exclude-etc-hosts to true changed browser.fixup.dns_first_for_single_words to true changed network.dns.offline-local to false restarted FF, rebooted computer

It doesn't work in Chrome either, which makes me wonder if it's a Windows 10 issue. Any suggestions?

Hi Everyone,

ever since the latest Firefox update, the "read more" feature on LinkedIn pages (personal pages, not the feed) does not show up anymore, at least not for me - the feature allows you to expand the various subsections to read their full content.

I opened LinkedIn on Chrome and Edge to see if it is indeed a browser issue, and it's working fine over there. I also did some troubleshooting (refreshing, clearing cache), but to no avail.

Does anybody else have the same problem?

Thank you!

I am trying to fix Firefox performance issues. I recently changed to Firefox to escape forced ads on chrome and the lost support for the Ublock origin. But I am having difficulty performing tasks and pages That I used to be able to do on Chrome with no difficulty.

When I open multiple tabs at once the tabs freeze up when trying to load and already opened tabs freeze and anything streaming also freeze. It takes tons of time to load multiple tabs and even sometimes single tabs depending on the website. This never happened with Chrome and I understand Firefox is not as refined as Chrome and is far younger than Chrome is but I feel like it shouldn't be this bad. Is there any settings maybe or maybe settings/preferences in the config area area that might help with faster performance and increased multitasking ability in the Firefox browser?

I have tried

1. Updating Firefox - I am running the most up to date version 2. Updating Graphics Drivers- I am running the most up to date drivers(Updated yesterday 11/17/2024 3. Deleting Cache/History/Logs 4. removed or disables unneeded extensions that I don't use every day and only activate when I need them.

None of this has worked to increase performance.

P.S. I would also like to fix the problem where firefox is using too much RAM if possible.

Can anyone help me?

'Linked In' technical support are telling me that I am unable to see certain pages on their system most likely because my Firefox Browser (which is fully up to date) is using DNS. They said to remove DNS. Is this wise advice and if so how do I do that and what difference will it make to my day to day use of firefox?

You used to have a nice menu bar, with bookmarks easily available. Now it looks like Edge, with bookmarks over on a right hand menu, with multiple clicks needed. I looked for a View option in settings and found nothing, searching on toolbar also comes up empty.

Is there a way to get that old menu bar to show back up?

I have been having this issue for a while now. I will get this message on different websites, and then if I try again later it might work. It seems like it's a random chance of me getting this error. I have tried "about:config" commands as suggested on other posts on this forum and they didn't work. I checked my licenses, proxy settings and still nothing. I got another web browser to see if it's my PC or Firefox, and the other browser worked just fine. I am guessing there is something I need to do within Firefox, but I am not sure what that is.

I’ve noticed that Firefox is draining my Mac’s battery significantly often consuming over 200% of the device’s power. It also prevents my Mac from going to sleep when not in use. Is there a setting I can adjust to improve battery efficiency and ensure that Firefox doesn’t block my device from entering sleep mode? I’d appreciate any guidance to resolve this issue.

I have manually installed multiple older versions of Firefox for Desktop (Windows 10), as I am translating KB articles and sometimes need any of the twenty latest versions to get screenshots in my language for the translated articles.

When an older version becomes superfluous, I would like to uninstall it from my computer, but that does not work. Even though I see all the older Firefox versions listed in Windows Applications & Features and each of them has an Uninstall button (and a helper.exe file in the uninstall folder in the installation folder each of the versions), the only "action" I see is that I get a warning that the Firefox Helper application is about to make change to the content of my hard drive, and will I allow that? The pop-up asking if I want to refresh Firefox instead of uninstalling, it does NOT appear.

The only time I get a proper response, i.e the Refresh-instead-of-uninstall? pop-up, is when I initiate uninstall of the latest current version of Firefox, in my case Fx132.0.2.

Have anyone else come across this problem?

Is it possible to click individual segments of an URL in the address bar to navigate there directly (without manually selecting and deleting the tail)? It's a convenient way to reach upper layers of a website.

For example Vivaldi implements it via Ctrl+<Mouseover/click> (see attached screen capture)

Is there an option or addon to enable this? Thanks in advance

I'm an author, publishing through KDP since 2022. As a UK resident, I publish initially on amazon.co.uk, after which Amazon sends the ebooks and print books to amazon.com and so forth. However, when I view the books on the US site, they are shown as 'currently unavailable.' This only happens in Firefox. I also use Chrome now and again, and it's fine there. The books clearly are available, because US readers buy them. But clearly I don't want to risk any US Firefox readers thinking they're unavailable, if they have the same problem that I'm having. I raised this with Amazon a while ago, but they said it was nothing to do with them, and must be an issue with my browser. I've recently published the third book in a series, and it's just the same. Any suggestions?

When I open Firefox on the desktop computer it automatically opens all of the tabs in bookmarks instead of just a singe page. How can I get it to stop opening all of the bookmarks automatically?

i restarted firefox, and on it's new tab when re-opening it offered the "review checker", so i clicked the "try on amazon" I don't get the icon in my search bar. is it an add-on/extension that i can just search for in the google store even though it's in beta?
