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?

I just updated to the latest Thunderbird version 128.5.0esr, Build ID 20241125170630 and after relaunching, all the email in my Sent folder is gone.

Running on a Windows 10 machine. Can someone explain or help guide & restore my old Sent folder?

Thanks!

How do I stop it from appearing please? It's the address bar.. field. I don't know what to call it, english is not my native language. I just want it to remain small and static like it always did. Now it becomes a huge field that takes up too much space and blocks my vision and I just want it to disappear.

I wish Firefox would stop changing stuff like this.

Today when I launched the browser, a sidebar appeared. No matter what I tried, I can't remove it, it really gets in the way, I searched for information all over the Internet, but I still couldn't find any information. How can I remove the sidebar?

Hi

I am unable to connect to TELUS email which is operated by Google. The unit is a new SAMSUNG Tablet 9A and is owned by a friend. I installed Thunderbird for Android on the unit. I cannot set it up because it requires OAuth2 Authentication and it is not available within the TB for Android. I use TB on many units using Linux and they work fine.

I do not want to use Gmail client but maybe I have to. Is there anyone aware of how to solve this problem so I can set him up with TB, which I prefer? Robert

All of a sudden, when I'm on eBay, a lot of the hot links, embedded on an eBay "for sale" item don't work. Sometimes, when I (repeatedly) hit "Reload Current Page", they start working, or become "hot", as they should be. I wrote eBay, but no response. I don't know, if it's their problem, or something wrong with Firefox. Thanks, in advance, David

Why is there no price tag icon for Review Checker in the search bar for Amazon and Walmart? (I am signed in to Mozilla, and I tried turning off all my adblockers and Privacy Badger.)

Thank you for your suggestions!

A few weeks ago after an automatic update I ended up having Thunderbird version 131.0.1 installed, I have no idea how this happened. On opening I get a message telling me I shouldn't be using a beta version and that I should revert to the latest general release version (128.4)

Today when I had some free time I downloaded 128.4 and installed it. On opening it it says that I can't use a profile file from a later version with the earlier version. Is there a way to recover from this WITHOUT having to set up the whole profile again from scratch.

Meanwhile I have done a system restore so I am back with 131.0.1 It has not given me any problems so far. Is there a new general release version imminent that will get me back on track?

I would appreciate any help I am not a computer expert, just a user, and find Thunderbird a very good email client.

I view movies and tv series on Amazon Prime and others every night . Suddenly I no longer can. On Prime I get a msg. saying I must update ff. It tells me the process and I have done it at least 6 times. When I go to 'about Firefox it tells me that I am already up to date, have version 115.18 esr. I am on a Dell Business computer, Vostro 470. Windows 7, service pak 1. Processor is i5-3450CPU @3.10GHz. RAM 400 GB , 4 processor cores. 64 bit. Prime disk466 GB 395 GB free. I'm a senior lady, not very computer literate. I have a ton of duplicate files but don't know which to remove. If I got help I could free up a lot more space. I watch everything on my computer monitor. I don't understand as the esr was supposed to allow us to continue. Please help as I am pretty homebound and this is about my only entertainment.
