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 have payment methods saved. On payment sites, I click on the CC# input box, and I am given the option to use one of my saved payments. I mouse-over payment choice, and it populates the input boxes with the correct information, however once I actually click the payment method, the payment method and all the input boxes are cleared of all contents. I am therefore forced to enter payment information each and every time I want to use it. The Fill Payment method isn't working.

I have reentered and verified the saved payment method several times.

I have a situation where I constantly have to send tabs from mobile Firefox to desktop Firefox. So I use Send tab to device feature. But when sending, manually clicking on the Synchronise now button in the Account menu of the toolbar of the receiving device is often needed, or else it would take a while for the tabs to be received. But I find that annoying and unintuitive.

Is there a solution for it? For instance, syncing Firefox devices more often, maybe just for the sending tabs feature because sync-now also syncs history, and bookmarks.

Yet another sterling example of why change is usually bad. Why did Firefox, Google and other browsers (though don't know about Duck Duck Go) drop the 100 results per page option? I've always had that enabled and now that it was removed it makes searching extremely tedious and time wasting. Please offer a SIMPLE AND QUICK way to restore this option ASAP. Thank you.

I recently restarted my computer, and when I started my computer, the text on all my apps was tiny. The text is also tiny in the search bar and book marks in firefox as well. I have restarted my computer several times, and the issue with desktop apps seems to have fixed itself. The firefox issue has not.

The text in the tab, the search bar, and the bookmark name is all tiny and I can barely read it. Everything else is normal and this is not a problem with other browsers. I have tried switching the text size in firefox settings, I have changed the text size in windows display settings, and I have even tried changing the overall size of the browser through "about:config" and changing the "layout.css.devPixelsPerPx" to a higher number, but nothing works.

I can use the app just fine, but I cannot read the text in the tab, search bar, or bookmark.

If i open firefox and then open a new window or tab in firefox with the same adress, it will close it down. Why would anyone want that function? The reason i open the second tab our window is because i want them open simultaneously of course. Damn that was one annoying feature, it even changes window if i have multiple tabs open and one tab i the same as in the other window, jesus.

When is Firefox (across devices) going to bring "Tab Groups" in-built in 2025 as it is difficult to ditch Chrome esp., if it is related to work or research and similar tabs are opened up?

I have to rely on chrome and edge for same and both have not only brought it but improved it considerably. Also, chrome has not brought for mobile devices so grouping of tabs is more easy and simple but when I look at Firefox and Firefox based browsers, I see nothing of that thing present. The addon esp., Simple Tab Groups (https://addons.mozilla.org/en-CA/firefox/addon/simple-tab-groups/) is unreliable (see reviews).

If Firefox want us to use their browser and as default, they should see why we are using Chrome and Edge (latter, having vertical tabs in-built, also).

I hope 2025 is a year Firefox learns of how to retain users across devices. Currently Firefox is more from 2005.

Browser Choice Alliance wont be helpful if browsers like Firefox dont see users and their reviews and posts and issues reported. "https://browserchoicealliance.org/"

3 years post and still no work, and Firefox wants us to use their browser over Chrome and Edge. Why? And how?

Granted, yes, "human error". But even so, I cannot even imagine what kind of dexterity I would have needed to accidentally change my language settings from English to I'm not sure which language, I thought Thai at first but no, who knows, maybe Cambodian?

I accidentally told Firefox to autofill a password for a website. I have followed all methods I found on web & in Mozilla support without success., except I don't want to stop or delete ALL autofills. Firefox doesn't show this password as saved (even when I search for it by URL), and the "Saved Logins" section of "passwords & security" [in settings] NO longer exists. I do NOT want to delete all autofills. I also checked my settings for this website, and it is NOT causing the autofill. Please: How do I stop Firefox from autofilling of a password for a SINGLE website? Thank you!

Hello!

I have a problem with FF browser on my PC for quite some time. It seems that every time I try searching for anything at all, there always appear a "google location bar", which obstructs the first search result completely - more in the attachment.

I've tried turning off all of the add-ons I have, tried searching for it in console, tried blocking it - didn't help.

It doesn't show in other browsers.

Is it possible to bookmark a particular section of a page, whereas the bookmark will take you to that location?

Textmarker was suggested in another thread, but apparently it is no longer working.

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 Please? And if possible please give as many solutions as you can find or know so I can implement them quickly.

Yahoo isn't loading at all for me, more specifically guce.yahoo.com. I have managed to get into the login.yahoo.com page and log in but after the log in process it goes to the first page again and gives me the same "The connection has timed out". I just installed the browser and this might make me not use it ngl. I have tried both clearing cookies and troubleshooting mode.

Hi.

Why are there so many updates for Firefox? If signing me out of all my open tabs is for security reasons, then cntl-shft-t defies that purpose? I will just contineu my search for another browser to use instead of Firefox.

Thanks.

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
