I'm trying to add the world cup tracker to my home screen, but when i click the link, it just puts me in my new tab page with no changes. When I click the pencil edit icon, widgets are not an option for me. Is there a place I need to enable them?

My old laptop died, stranding my Firefox profile (including bookmarks and Login credentials for many sites). I am able to connect the old laptop's HDD via USB to port the old profile data to the new laptop, but I am afraid that copying the older files to the new profile will overwrite the newer profile data. I would like to create a second profile, in which to store the old data, in the newer laptop's instantiation of Firefox, but I don't see any information online about doing this. Is it possible to create multiple profiles in Firefox for this purpose? Thank you

A website I user, www.advisor.ca, displays a banner across the top which obscures some of the text in Firefox but displays correctly in Chrome. The attached images are for the page https://www.advisor.ca/tax/tax-news/court-dismisses-challenge-to-cras-administration-of-cap-gains-tax-proposal/. I expect this is one of those things that Chrome does 'wrong' but I would like to know if there is something I can do to make it display correctly in Firefox, of if FF could handle it in some manner.

Thanks.

I am trying to change my default search engine to Firefox and it isn't allowing me. What could be preventing this? and how do I get around it? Thank you in advance for your help.

Multiple attempts to open Firefox produced a popup window indicating that "platform version 153.0 is not compatible with min version 152.0.6 max version 152.0.6 Maybe try to reinstall Firefox." If this is the only solution, how do I do this and retain my bookmarks, themes, etc profile? Thank you.

A month ago, I raised this question, but there was no answer. The problem is still here, and forgive me for posting it again. Maybe this time someone experienced will see it. Let me know if you encounter the same problem, maybe we can discuss it out. And thank you to everyone who spares time to read this post. Below is the original question. I'm a Chinese firefox user, so the following descriptions are translated and may not be so accurate. And the attached image is also Chinese, if necessary please use a translation app or somewhat to see it. I have only one default profile in my Firefox account, and I have stored a large number of passwords and bookmarks in this default profile. For certain reasons, I signed out of this profile while retaining the local data such as passwords—meaning that, apart from not being logged in, my browser state remains exactly the same as before. Now I wish to sign back in to enable synchronization. I can see a "Sync and Save Data" button prompting me to log in. After clicking this button, I am asked to enter my username and password, but then I receive a message stating that I have reached the account limit for this profile, and that this profile was previously synced to another account. This is absurd, as I do not have another account, nor have I ever synced this profile to any so-called other account. As a result, I am unable to sign in on this current profile.

I came to know about Firefox Widgets but can't see any on Firefox 152 on Windows 11 desktop. The option Allow Firefox to improve features, performance and stability between updates is already checked (Screenshot attached) as suggested by users.

Our team has already tried to fix the issue for a week now and none of the approaches seem to fix the issue. Does the Firefox dev department have any hints or clues for us?

Short description: Firefox network.lna.blocking blocks same-origin/loopback requests when the page is controlled by a Service Worker

Symptom: Login via OIDC fails in Firefox (the backend call after the IdP redirect is blocked). The error disappears if either network.lna.blocking=false is set or the Service Worker is disabled.

Environment: - Frontend (react) and backend run on the same machine (loopback/localhost)—no cross-network scenario. - Firefox with active network.lna.blocking (experimental Local Network Access feature, Chromium’s equivalent is Private Network Access).

Root Cause (Analysis): 1. apps/react/sw.js registers a global fetch listener via Workbox and calls workbox.core.clientsClaim(). This causes every open page to be immediately controlled by the Service Worker. 2. registerServiceWorker() is called unconditionally on every app start, regardless of authentication state—even on the login/OIDC page. 3. The app uses hash-routing (URL fragments like “#/oidc”); the login page and the rest of the app share the same document URL, so you can’t restrict the SW scope to “everything except login.” 4. Once a page is Service-Worker-controlled, every fetch—including requests not explicitly handled by Workbox routes—first goes through the SW’s fetch event (default behavior when any fetch listener is registered) before proceeding to the network if it isn’t intercepted. 5. Hypothesis: Firefox’s LNA implementation doesn’t correctly inherit the address-space classification (loopback/private/public) for SW-forwarded requests across the controlling client. A direct document fetch (loopback→loopback) is allowed, but an identical target fetch routed through the SW is blocked.

Reproduction (minimal): 1. Use Firefox with network.lna.blocking=true (the default in affected versions). 2. Load a page that registers a Service Worker with a fetch-event listener (e.g. via Workbox precacheAndRoute + clientsClaim()). 3. Ensure both the page and the target resource are served from localhost/loopback. 4. From the SW-controlled page, call fetch() against the loopback target resource → the request is blocked. 5. By comparison, the same fetch from a non-SW-controlled page succeeds. 6. Setting network.lna.blocking=false also allows the fetch to succeed under SW control.

Excluded Causes: - Different address spaces for frontend/backend (both are on the same loopback machine)—ruled out. - Misclassification due to redirect_uri or cross-origin navigation—the OIDC redirect is a top-level navigation (unaffected); only the subsequent backend call (token exchange/session validation in SsoLogin.tsx → ssoLoginSubmit) fails.

I've had a problem for a while where Firefox tells me "Firefox is being updated by another instance" and the only way I've been able to get updates is by using the installer.

In my attempts to resolve this, I learned of the `about:profiles`. I have never set up profiles so I figures I should only have the 1 default profile but it turns out I have `default`, `default-release`, default-release-1`, and `default-release-2`.

Of these profiles, the `default-release` is the 1 that has my data while it is `default-release-1` that is able to update.

I would like to make it so that I only have 1 profile that has all of my data AND is able to update.

I already tried removing all the profiles accept the one with my data but that leaves Firefox unable to update. I restored all the profiles I removed and I am back to where I started.

Does anyone have any suggestions?

I've been using the extension "Tree Style Tab" and "TST Colored Tabs." I've been looking for a way to disable the native Firefox tab bar, whether on top of the window or to the left side. I haven't been successful on my own.

After a couple of hours troubleshooting this with CoPilot, It suggested I post the following short summary:

============

Firefox 152.0.6 (64-bit) about:profiles shows active profile: C:\Users\dmerc\AppData\Roaming\Mozilla\Firefox\Profiles\usm8kxcr.default-release

Opening that directory from about:support shows an empty folder.

profiles.ini references: agwp164m.default-release

userChrome.css loads correctly in a separate profile but not in the profile containing my current extensions and history.

============

The details of how it came to this conclusion:

============

Based on everything you've found:

The profile with your current extensions and recent history is reported as: usm8kxcr.default-release

Opening that profile folder shows an empty directory. The only other real profile on disk is: agwp164m.default-release

We successfully proved userChrome.css loads in a different test profile (Profile 1) because the toolbar turned red. Therefore, the CSS mechanism itself works on your machine.

My conclusion is that your Firefox profile registration has become inconsistent. Firefox appears to be using a profile that does not correspond cleanly to the profile folders you're seeing in Explorer. At this point I would:

Back up the entire folder: (NOTE: DONE - backed to to another drive) C:\Users\dmerc\AppData\Roaming\Mozilla\Firefox

Keep using the profile that contains your extensions and recent history. Avoid deleting any profiles or profile folders.

Post the details you've collected to either: the Mozilla Support forum, or r/firefox

The key facts to provide are: Firefox 152.0.6 (64-bit)about:profiles shows active profile: C:\Users\dmerc\AppData\Roaming\Mozilla\Firefox\Profiles\usm8kxcr.default-release.

Opening that directory from about:support shows an empty folder.

profiles.ini references: agwp164m.default-release

userChrome.css loads correctly in a separate profile but not in the profile containing my current extensions and history. \ Those facts point to a profile-management issue rather than a Tree Style Tab or CSS issue.

The good news is that your current extensions and recent history are still accessible, so this doesn't look like data loss. The profile mapping itself needs to be untangled before custom CSS can reliably be applied.

It also suggested not copying any folders and files between profiles for now.

Firefox 152.0.6

1. I go to X.com and am presented with the logon screen and the option to logon using Email or Username, Phone, Google and Apple.

2. Try entering my email address in the logon screen and get a red ! error: "Please enter a username, email, or phone number."

3. Try entering my username in the logon screen and get a red ! error: "Please enter a username, email, or phone number."

4. Try using the Google option and it performs as if I was logged in but the system never leaves the logon screen.

5. Try using the Phone option and enter my phone number and get a red ! error: "Something went wrong. Please try again."

6. Delete all history, cookies, etc. Restart Firefox. Same issues as above.

7. I disable all Extensions and restart Firefox. Same issues as above.

8. I try a Private window and am able to log in just fine.

I am at a loss here on how to proceed. This is happening on two individual systems in my home both running the same version of Firefox.

I have Brave set as default search engine. I type in the address bar, hit enter, and always get a Brave screen with "404 Nothing matches the given URI". I downloaded the Brave browser and the problem goes away. But I prefer Firefox as my browser, so I'm hoping there is an easy fix to this.

why every time i open Firefox is go straight to signalqueryhub instead firefox. And how i can make it like normal(open Firefox and straight to Firefox instead of signalqueryhub).
