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?

Recently I haven't been able to sign into Coinbase. When I first try to sign in I just get the spinning circle for a minute or two as seen in the first photo attachment. It then turns into the second image I have attached. It appears to have to do with "human" verification. I set Coinbase as an exception everywhere I can in the setting with no change. This is a recent issue as it only started in September so there a recent change with Firefox. I am able to sign into all other websites without any issue and can sign into Coinbase with every other browser so this is very specific and only applies to Coinbase on Firefox. Why I unable to sign in?

My gmail mail account does not pull up on firefox ,works on Microsoft Chrome Brave . 3 days and counting . This the 2nd time I lost the ability to have something work. The last thing last week was my Metamask Wallet was not loading I had to reinstall it.Thanks Stephen Machlica

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.

All of my desktop bookmarks are on mobile, but after resetting my password they won't sync back to my desktop. I can't even access them from my desktop, despite browsing data still being clearly accessible. I have 10 years of bookmarks on my mobile device that for whatever reason now will not transfer to my desktop firefox no matter what I try. Since there's no way to manually export to xml on mobile I have no way of accessing these and I am at risk of losing 10 years of bookmarks, many of which are vital to the work I do.

Hello

I use Firefox 132.0.1 under Fedora 14 Linux. Whenever I click an urls in another application (e.g. Libreoffice, Keepass...) a new tab is opened in Firefox (according to Firefox's settings), but Firefox itself does not pop up in the foreground, it remains in the background. I highly appreciate the setting 'open links in tabs instead of new windows'. But FF only comes to foreground in case I deactivate 'open links in tabs instead of new windows'. How can I prevent FF to stay in the background in case 'open links in tabs instead of new windows' is enabled?

Thank you in advance

When I send an email using Gmail, Firefox stores a copy in "Sent Mail", another copy in "Sent", and another copy in "All mail" . Why is this and how can I stop this? Or how can I delete two of the duplicated storage locations? Thank you

Hi there, why some sites are not recognising that I have installed the wallets on the sites on firefox, when it works on other browsers ? is there any settting I need to adjust or something ??? I just installed a couple fo aptos wallets, pontem and nightly wallts. thanks

Recently a new sidebar appeared on Firefox on my desktop. I actually really liked the change because I have wanted to move my tabs to the side for a while. I had tree style tabs installed and I was a little annoyed that I couldn't disable the tabs on the top bar. But now I can!

My laptop however does not have the new sidebar yet and when I look for updates it says there aren't any. My laptop has limited screen space and I much prefer to have this new ui choice but I can't enable it. I understand that they probably update new designs in batches to test the waters but is there a way to get around it and enable it on my laptop too?

I use the same Firefox account for both so it seems a little counterintuitive to have different experiences on different devices on the same account.

Also very much thank you for this change! It's something I've wanted for a while. I also have one little suggestion and that is to have the option for a similar feature to tree style tabs on the sidebar tab layout.

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!

Why does the map "https://vsoc.org.uk/club-history/where-we-meet" not load in Firefox, but it loads in all other browsers?

'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?
