Hello, so I am not very experienced and recently discovered how to customize Fire Fox using the userChrome.css file. I went through all of the steps that are required in order to do this. I set up a folder called chrome in the directory /Users/my name/Library/Application Support/Firefox/Profiles/x1oheo82.default-release To test if it works I wrote this into the userChrome.css file: @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* set default namespace to XUL */

1. TabsToolbar{ background-color: #FF0000 !important }

and set toolkit.legacyUserProfileCustomizations.stylesheets to true After restarting Fire Fox I saw that nothing changed. I double checked if there was a hidden file extension or if I might be in the wrong directory. I tried different code to see if there was some error in the code but nothing changed. I watched countless tutorials on You Tube and tried to find answers on google but nothing that I did seemed to help. I don't know if it has something to do with the operating system I am running or if it is a limitation of my computer hardware (I am running Fire Fox on an m1 mac).

When I load Amazon.com, the webpage is a lot of text and random pictures. Amazon's layout is broken. I loaded the same page in Chrome and Safari without a problem. I reinstalled Firefox 99.0.1 without any improvement. Please fix.

I got help with this from your group some weeks ago, but I had to reinstall my Ubuntu OS (linux v.20.04.4 -- using firefox) recently and can't recall the answer.

When I view a WikiSpecies list of file names (e. g., see https://species.wikimedia.org/wiki/Pentatominae), the instances which have been installed but never used should be in a different (reddish) color. I am attaching an image of a page containing a file named "Abadia" (first one on the left, just under "A") which is unused. I also am attaching an empty "Creating Abadia" which is the result of clicking on "Abadia".

Please tell me how to change the image of an unused, empty file. I recall that there were two different choices SOMEWHERE in the system, "Always" and "Never" I think: One of them forces a system-level color pattern which includes reddish unused items; the other allows the used to program arbitrary displays such as the above (typical example from the dconf editor is 'bg_color: #f0f1f2; selected_bg_color: #023C88', but this editor does not change the appearance of a file instance.

I am developing an extension. I am running the extension locally and I have noticed that it doesn't load on this page (https://support.mozilla.org). Is there some limitation to running extensions here? The same extension works fine in google chrome for this page. It is very important for me that the extension runs everywhere since it's an accessibility extension.

i recently lost my computer to destruction. i have a number of files saved by Mozilla backup on a thumbdrive. i have several backup files dating from 2014 all the way until now. after re-installing Firefox on a new computer, i tried MozBackup to restore my old Firefox from the latest file dated a coupla of months ago this year. the files have names like Firefox 16.0.2 (en-US) - 2013-01-05.pcv or .pfc. when i tryt and load it into backup it saysit isn't a valid backup file. how can i get this to work?

For years I’ve had no difficulty accessing online my HSBC bank accounts in UK using Firefox. In recent days they have changed their security access method whereby their site now requests a security number generated on one’s phone using the HSBC App (it used to be a random number from an HSBC supplied handheld device) which then has to be input via my Windows 10 PC to access my data. If I use Microsoft Edge as browser, everything works fine, but when I try Firefox my system just hangs after I’ve put my bank ID into the HSBC opening page (the first security step) and simply never opens the next HSBC page which would ask me to generate the said code on my phone. Seems a browser related problem. Any ideas why Edge works but Firefox does not?

I am trying to use a new HP Spectre laptop which will be my all purpose home computer. I selected Firefox Browser as the default browser but I don't believe it has ever come up as my browser. It is loaded among many other apps (?). I used to call them programs (?). I get Edge, Chrome, Bing, and others, none of which I want or ask for. They just seem to appear randomly.

I download then open many student files each day. PDFs open fine automatically, but never Word files. In the Applications settings dialog, I have tried to choose the file format docx and doc. But neither are recognised as a valid file type. I realise that Microsoft is a bully and Mozilla may be trying to discourage its use, but I and the students are stuck with Word. How come docs and doc are invalid and how can I persuade Firefox to open them?

Thank you

I opened Firefox as usually, but passwords are missing, only logins are available. There is also a file called logins.json-1.corrupt in the profile folder.

Renaming it back to logins.json with restarting the computer does not work.

There are no previous versions of these two files available in the system.

Please let me know how I can recover passwords, may be with a special software.

Thank you!

Hi,Why is download showing up on nearly all sites I go to & HOW do I get rid of it permantently I can close it by hitting the X beside the Download,but it Should not be there Thanks Darryl

Hi, I'm having a problem with my Firefox where it doesn't let me change some of my settings. This is my home PC and I've already tried running Firefox as admin and the settings are still locked. I have reset it many times and haven't installed any extensions. I can't find anything online about this.

I am sending tabs from Firefox mobile to Firefox desktop (Arch Linux) (on a regular base for years). All worked fine. After a new install two weeks ago the Firefox desktop receives the tabs and opens them as supposed. But after a day or three when I open Firefox desktop it opens all previous tabs again together with the newly sent tabs. I deleted the Firefox profile and installed from Firefox sync but the problem occurs. I deleted all devices in sync and added my 2 devices (desktop and mobile) again but it didn't work. Does anybody have a similar problem (and a solution)?

Walmart website no longer works properly with latest Firefox 96.0.2 64-bit. It works properly with Chrome and other browsers. You can log onto the site and search for products but when you try to add a product to the cart nothing happens. You also can't actually go to the cart. Last time I used Walmart was a few weeks ago and everything worked fine!

I read that with version 100 on the Mac there will be some problems with some web pages like my bank can you tell me if this has been fixed or not, if not I don't want to go past version 99. Thanks for all help Michael Whitecotton

firefox updated itself, which normally would be fine, but now there is a PDF icon in place of my normal firefox icon, and I am afraid to use it now. Is it for real?, can I change the icon back to the old firefox one? Please let me know cause I won't use it now until I know for sure that it's ok and get it back as it was. thank you, Linda

The instructions for the Window Titler icon suggest to turn on the Title Bar (with the Firefox icon, usually shows title of active tab, but would presumably show the Window Title if one was assigned). I can't find how to turn it on in version 99.0.1. It's not where the instructions for Window Titler said to look (managing the Menu bar or the Bookmarks bar). Any suggestions?

Would love for this feature (named windows) to become a normal part of Firefox. I wouldn't mind having the Title Bar anyway; at the cost of a few pixels, I would have something to grab onto when moving windows around that wouldn't accidentally do something to a tab.
