With FF 140.0 on both WIn10 and WIn11, new tabs opened automatically then closed after less than a second. Initially I thought this was due to malware, but on inspecting the History, I found the source of this annoying behavior:

// SidebarUtil.tab.js

// This is just a placeholder file to be loaded in a temporary tab to check if a sidebar is open and how wide it is.

Is there a way to STOP this sidebar checking with its tab opening/closing without disabling Java entirely ? Is this annoying behavior really necessary in FF ?

Hello everyone,

Is there any software that allows software developers to see what the CSS they are creating is doing in real time ?

Because I can't imagine they're doing it blindly. I see some CSS files that have hundreds, possibly thousands, of lines.

If there is software that helps them see immediately what their CSS is doing, can it be used to create extensions (add-ons) for Firefox ?

Thank you for your attention.

Please change the switch in your code back to normal. Its just a tiny switch! normal is=task bar context menu by right clicking on the task bar WITHOUT "title bar". Is this so hard? And why is such important thing not fixed in 7 months?

I tried to reach the following adress: https://www.itu.int/harmful-interference-to-rnss/ and I received this message on my browser: 400 Bad Request -Request Header Or Cookie Too Large

When I tried from a different browser it was accessible.

After tinkering with about:config (shouldn't have...) the background of every page that does not specify a body background color turns the color of my theme background color.

Using the firefox color pipette says its white, but it clearly isn't.

The theme i have is dark, making any page that expects the background to be white unreadable (without DevTools -> Body -> background-color: white)

I haven't been able to find the config that fixes it.

So i've lost access to my email on. my old mozilla accounts and upon logging in on a new device im being asked for a code to the email which i don't have access to anymore is there a way that my info can be synced to a new one. Thanks

McFee is trying to sell us computer protection. We have had Firefox for several years. I am now getting an alert to Turn On Firefox. How would it get turned off, and how do I turn it on without going through Mozilla's selling site?

I am using version 140 on Linux and now two company sites do not work properly when "enhanced trakcing protection" is enabled. The 2 companies are "public mobile" a Cell phone provider and "Voip.ms" a phone provider.

When I log onto public mobile I cannot view my specific account information, I can see other menu information. voip.ms I cannot log on either chat or the main customer portal. This only recently changed within the last 4 days and I am using the same version of firefox.

Can you provide an explanation as to why this is occurring?

I was asked to create a new profile in order to keep using Firefox, despite never having an account. After I clicked okay, it opened the new version of Firefox, but without all the passwords, bookmarks and history of the past few years. This is really inconvenient. I have since then made an account, but the fact that I can't find any of this data anywhere has me worried that every time I update Firefox it will wipe my account.

Clicking "bookmark current tab " does not offer dropdown menu to assign bookmark location. Clicking "bookmark current tab" places bookmark in last used bookmark folder. Workaround is to "edit bookmark" and assign desired location.

I have Firefox running on 3 machines, only one of them is synced to my Firefox account, so that means that I am not running the same addons on all of them. I have Firefox running on Windows 10 and the two other are running on Windows 11. From time to time, I notice that Firefox is running slow and its unable to open normal websites like facebook, instagram, youtube, or any other website that I normally browse, and when I check the Task Manager I can notice one unusual exe running named "crashhelper.exe" which is located in the Firefox installation directory and its signed by Mozilla. Once I kill this task Firefox continues working as nothing happened. This is happening since the last update which was few weeks ago (if I remember correctly). What is this app doing and why it is making Firefox stop opening websites?
