I am using Firefox Developer Edition Version: 110.0b5 (64-bit) on M1 Mac running Ventura 13.1.

I am building an webapp some XHR triggering in background but it is not necessary to run the application (running fine on other browsers). But on Firefox Developer Edition, It shows a error window with the message and stops loading the application.

Firefox can’t establish a connection to the server at localhost:4000.

localhost:4000 is the failing XHR request domain. I have attached the screenshot.

How to ignore the XHR failing errors just like other browsers?

hello guys I need help with this problem in firefox developed edition

Specifically, when I use the Inspector panel to inspect elements on a webpage, the selected elements are outlined with a blue border instead of being filled with color. This is making it difficult for me to visualize the layout and styling of the elements, and I would prefer to have them filled with color instead.

I have tried to find a solution on my own by searching online, but have not been able to find a clear answer. Could you please advise me on how to change the settings in Firefox Developer Edition so that the Inspector panel highlights elements with a fill color instead of just an outline?

Hi,

im getting unknown issuer on my thin-clients with a FF ESR 45.9.0. This FF is tied to the OS (Ubuntu 16.04) and the OS is the most recent compatible version for our version of the thin-clients. So yeah its super old and I'm not able to update any of this. There is no security.enterprise_roots.enabled option available. What would be the best way to solve this issue for ~400 clients. Thanks in Advance Regards Tekkion

Before the update, my bookmarks toolbox was permanently open on the left side of the screen. That was a perfect setup for me, as I use a lot of bookmarklets for time saving on sites I'm on frequently. Since the update, all I have at the top of the screen is Import bookmarks and Most Visited (top left) and Other Bookmarks (top right). I can open Other Bookmarks, and my bookmarklets are there, but clicking one closes the Other Bookmarks folder each and every time. This renders them useless for my purpose. Is there a way to reopen, and KEEP open, my toolbox? I've tried clicking the Keep Open option and selecting done, but that doesn't do what I'm wanting it to do.

One of the beauties of firefox has long been that I could use the backspace bar instead of the back button to return to the previous page when browsing. Somewhere in the last updates this wonderful functionality was lost. Is there anyway I can restore this? I'm suffering from Parkinson's Disease which oftentimes makes controlling my mouse nearly impossible.

Is it still necessary to use both !important and @namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul) inside userChrome?

Since couple of months ago, FF started to ask for master password after 30 minutes of inactivity. I have auto-refresh for some tabs which use Basic Authentication. After 30min those tabs stops refreshing and FF opens multiple (5) dialogs for master password. This secondary layer of security is pretty annoying as I have my computer secured on multiple levels by multiple factors already. I am getting very annoyed by this, is there any way to disable this "feature"? I have security.ask_for_password = 0 and signon.masterPasswordReprompt.timeout_ms = 0 but it keeps asking (now bit less often but still does). I just want master password entered once when I start the session and keep it open until I quit the browser.

Hello,

I love the tagging bookmarks feature in Firefox. But unfortunately it does not work properly like explained in the help docs.

I search for tags by typing '[+] + [Tag]'. This works for me but I only can search for 10 entries maximum.

Why there is this limitation to bookmark entries in my search bar? And how can I see all my tagged entries even when there are more than 10?

Kind regards Benni

In my "saved addresses" list under the Privacy and Security section of Firefox Settings, there are two addresses of people that have never used my computer. One formerly went to my school, and the other is a stranger. I can think of no way that they could have had access to my account at any time. Are there any other possible explanations for this?

I have set Firefox Developer Edition (Windows 10 20H2 & 21H2 and Ubuntu 18.04 & 20.04 installations, always kept up to date), to use English (United Kingdom) settings in preferences. I have installed the UK Dictionary and made it the default for spellchecking. The Windows installation is also supposed to be respecting the OS regional settings. Firefox seems to be totally disregarding the settings and always giving me US as the location and US English for the spellcheck. This has been an issue for months if not years. I understand that many pages will be US biased, that is not a problem. The problems are that my country preference is being detected as US, and that I can not seem to get Firefox to actually use the UK Dictionary. I can supply additional information as required

I browse web, I see an image to save. prior to today (03-09-2022) I click save as and it saved file to my downloads folder. but today, I click save as and instantly the list of files I saved pops up on right side. below the list of files it shows "show all downloads"

this window is easily accessible by left clicking clicking the download icon. i do not want this box popping up on each file/image saved. or rather, why is it doing it suddenly?

In order to more convenient drag-and-drop interface, I need a fixed fixed space in nav-bar like Edge. For now we can add a flexible space on it. But it's flexible and it will disappear when I use a side window. And I can't drag over titlebar-buttonbox-container Please help me. Thanks!

I can't open Firefox. When I click on the icon Bing shows up. I downloaded the latest version of Firefox, I can't install it because I get the message that I have to close Firefox because it is running. How can it be? I haven't been able to open it for weeks.

Thank You!

I had set up a userContent.css file in the past to pull up and fetch an image on my computer to display as a background on the homepage. It worked and did it's job until recently, when I had recently relocated a lot of my files around on my computer. I have redirected everything to where I want it to look, including the userContent.css file to the new location for the image I want as the background. Firefox loads the .css file correctly, and recognizes the file existing, but it won't load the image itself for some odd reason. It states it "may not load or link the file" because of a security error, and thus, can't load the image. I never had to deal with this before. How can I get Firefox to be able to load my image like I want it to? I have screenshots that I can provide, but this site doesn't want to upload them at the moment.

Tell me how to reduce the size of buttons, tabs, and everything else BUT the fonts in my browsers. All of them have been affected. I've exhausted all of the normal "look in Settings and use your brain" options.

Firefox crashes (tested in troubleshoot mode) for this URL : Link which causes crash https://developers.google.com/android/guides/opensource#java

I use HTML files to create images for a tile based game we play. 6 months ago I was able to create a table with collapsed borders and 0px padding, margins, and borders, then draw my image with 207 x 207 JPEG TDs in multiple TR rows, then place another GIF image over all the JPEGs with transparent edges. Doing this for a table that was 6 tiles (207px) wide and 4 tiles deep, at ctrl 0, displayed a Firefox combined image that was exactly 1242px x 828px that was completely visible on 24 inch 1920 x 1080 DELL monitor. This allowed me to right click an empty space on my Firefox screen and select Take Screenshot to click on the GIF overlay image and capture that image with all of the tiles that were behind its transparent edges.

For some reason, I have no idea why, my 207px by 207px tile images are now being displayed as 282px by 282px at ctrl 0, and the overall image is now too large to fit on the screen, so taking a screenshot of the proper sized image is no longer possible. For example, at ctrl- ctrl-, the tile images are 221 pixels square, which should be 1326 pixels wide for 6 tiles, but my 1242px wide GIF file displays at 1330 pixels wide, probably due to some kind of rounding error.

I was able to use about:config and change layout.css.devPixelsPerPx from -1.0 to 0.74 and it did solve the problem. But it does so with a lot of warning for changing that default value!

So my question is simple: how does Firefox, on Windows 10, determine its screen pixel to Image px relationship? I need to know what to look at for the proper way to get my px to pixel ratio back to 1 to 1.

and this is what the final image looks like when you take a screenshot of the image https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-08-23-13-36-53-beae42.png
