Whether the file is opened internally or directly downloaded to the desktop, the file name will be automatically changed to garbled text。This led to me manually correcting the file name to be correct every time I downloaded, and my installation of the "Download File Name Encoding" plugin was also ineffective.

Firefox has been using more RAM and CPU on my system recently, especially with only a few tabs open. Is this expected behavior, or are there specific settings, extensions, or configurations I should check to improve performance?

Hello! After I was on vacation for about 2 months, I suddenly couldn't receive any more emails. "Login to the server imap... failed." Why this - and what can I do? Thanks!

In Firefox, the animation exhibits performance issues like stuttering, particularly in elements that rely on animateTransform and animate for movement or opacity transitions. This issue is not present in Chrome, where the animations run smoothly without any noticeable lag.

Expected Behavior: The animation should render smoothly on both Chrome and Firefox without any stuttering or lag, providing a seamless experience for users.

Steps to Reproduce:

Open the provided SVG code in Firefox.

Observe the animation, particularly the elements with animate and animateTransform attributes.

Notice the stuttering or lag compared to the smooth rendering in Chrome.

On Windows 10 with 64-bit Firefox, after updating from version 144 to 145, some local HTTP-only servers stopped working and became inaccessible. When I enter http://<local server name>, after a few seconds it automatically changes to https://<local server name>, and since no HTTPS service is running, it ends with a “Server not found” page. It seems to be related to DNS — accessing http://<IP address> works fine.

I tried a clean installation with a new user profile, but it didn’t help. Downgrading to version 144 fixes the problem, but at the cost of losing the user profile (which is a disaster). I also tried to check the HTTP-only settings (which I’ve never modified), but that didn’t help either.

Is anyone else experiencing the same issue?

Pages won't load, including the firefox home page, or the autoupdate URL. My home page news stories load no images.

The Firefox .dmg downloaded and installed over previous version. Firefox failed to load any pages. Firefox deleted from Applications folder and moved to Trash. The Firefox installation file downloaded again. Firefox failed again.

This is a bug report. The browser does not function.

Troubleshooting Information would have been added, but it included personal information. Sorry. "userAgent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:146.0) Gecko/20100101 Firefox/146.0" Specifically, Firefox/146.0.1 (64-bit)

Why isn't the Firefox browser supported by many services and social networks? They even state in the warning that Firefox is not supported! Why should users tolerate this?

Почему браузер FireFox не поддерживается многими сервисами и социальными сетями? Так и пишут в предупреждение, что этот браузер FireFox не поддерживается! Почему пользователи должны терпеть это?

Not sure how to explain this but in my settings on my phone a gardidio add pops up every time I go into my settings and no I don't want them to guard my phone I want to stop it they keep pushing me to get it 😠 😠

In version 146.0.1, or perhaps even earlier, I noticed that if you set a Primary Password to log in to the browser, you can reset it and log in simply by clicking the "Cancel" button. This allows you to access all of your user tabs and links. I hadn't noticed this before. It defeats the purpose of setting a Primary Password. I noticed similar issues in the Tor browser, but you can't set a Primary Password there at all, even though the feature is there, and it's built on the Fire Fox engine. Please fix this issue. No buttons should allow you to log in without entering the correct Primary Password.

My organization has an air-gapped development network in which we need to deploy an internally developed extension. We are attempting to do this via GPO with the latest version of Firefox ESR. We have been running into an issue where the extension is not being installed when the browser starts. After reviewing the distribution documentation for Firefox add-ons it appears that we have to submit the extension to be signed by Mozilla, the problem here is that our extension is on the air-gapped network and cannot be moved to an internet connected device per our clients policies.

I had read on this page page that Firefox ESR does allow unsigned extensions if you set `xpinstall.signatures.required` to `false` but that conflicts with the Add-on signing in Firefox support page that states: "Firefox Extended Support Release (ESR): Some versions allowed overrides, but most recent ESR releases also enforce signing."

So we appear to be at an impasse, we cannot have the extension signed and we are required to use the ESR version of Firefox (the Nightly and Developer versions are not allowed.) Is there anyway that we could selfsign the extension? Or bypass the requirement via GPO?
