Firefox Community Forum

Recently, I wanted to look up a car on CarGurus.com. I have used this site repeatedly with Firefox but it gave me "Cannot Access Website" error. I am an IT Tech and did a Cache Purge, then a deinstall-reinstall, and finally a Total and Complete Deinstall down to Registry level. No Help!!! Then someone responded on here saying they had the same problem. When I went to check, I was able to connect. Today, Same Thing!!! Chrome works, Firefox does not, so here I am writing again about an Issue I believe is a Firefox Issue. You need to look into this Folks!!!

Why can't I go to saltlife.com when I've gone to this 333 times and ordered items from them for YEARS? Also, when I'm at Kohls.com, I cannot access a site, when shopping to access part of my shopping experience. Am I going to have to change my browser to be able to shop there? I have used Firefox for years, and up until now, I've never had this problem.

I reset basically everything to see if I could get it to stop predicting what site I wanted to go to and it still does it. Cleared the history, turned off syncing, closed tabs on other devices before I turned off syncing. I see on setting for autofill address bars etc. Mobile firefox settings are reduced it seems. I am on IOS if that matter. I don't know what else would be useful.

I've tryed all obvious instructions and my bookmarks toolbar will not sync

Hello.

I clicked on a website that I did not recognised, and stupidly clicked 'allow' on the pop-up that appeared.

The website is "d6bimae071bc73d47f4g.lendexo.co.in"~

Despite having blocked this website from sending me notifcations, via the Mozilla Firefox settings page - they appear to continue.

The notifications propourt to be from McAfee, however, are coming from this website.

Mozilla made an update of my Firefox installation on my Win11 laptop. all my password disappeared as well as my history and bookmarks.

I have now a virgin installation and is starting from scratch.

Now I get this error message: "This profile was last used with a newer version of this application. Please create a new profile." I deleted met shortcut and I opened Firefox by using Windows search. Now I see 4 profiles! I think I do not need to create a new profile. Maybe delete 3 of them ? What to do ? And, how?

I use several devices with Firefox installed and I find that sync is not always "sync"-ing, or at least not very often. I can confirm I am logged-in the browsers. I do tend to leave my laptops in sleep mode and maybe sync is triggered only at browser closing? Whatever the case, I end up having bookmarks that I deleted from another machine still persisting on another for some reason or adding a bookmark on one laptop and not having it on another even hour later. Would you please take into account the option to sync at certain intervals like minutes, hours etc and let the user pick how often they want this?

Thanks! Constantin

I'm using Kubuntu 24.04. I saw it more than once. Firefox is frozen, no WiFi for example, and I have to kill it via terminal. After that it is not possible to retrieve the session (3 or 4 tab groups plus ~20 tabs)

thank you for any help.

При попытке демонстрировать экране (для совместного просмотра фильмов, например) с использованиием дискорд (веб версии) нет звука стрима. Проблема наблюдается **только** в браузере фаерфокс. В дискорде просто пропадает кнопка "поделиться звуком стрима/поделиться звуком системы" Никак не могу найти в настройках способ предоставления сайту доступа к звуку стрима/системы при демонстрации экрана. Может кто-то сталкивался с этой/схожей проблемой и у вас есть варианты решения?

Problem Description

In a server-based environment, I need to implement automatic updates for Mozilla Firefox, while maintaining strict outbound network control.

The architectural requirement is as follows: • Only the update component should be allowed to access the Internet via a proxy. • The browser itself (user browsing sessions) must not inherit or use that proxy configuration. • The proxy configuration for the update mechanism should be logically separated from the browser’s network configuration.

⸻

The Issue

In contrast to the update mechanism used by Google Chrome (Google Update / Omaha), where: • The updater runs as a separate system service • It supports dedicated proxy configuration • It does not inherit browser-level proxy settings • It allows granular control of outbound traffic exclusively for update operations

In Mozilla Firefox: • The update mechanism is tightly integrated with the browser • There is no native, dedicated proxy configuration exclusively for the updater • Proxy configuration applies to the entire browser • It is difficult to implement an “update-only network access” model

i been using my bank to pay my bills. but all of sudden i can't . it says my browser is outdated, but it isn't. the rest of the banking site works fine just my bill pay. and it works fine for everything else online.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to google.com because this website requires a secure connection.

What can you do about it?

google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Hello... I'm running Firefox on MacOS Catalina 10.15.7 on a 2013 MacBook Pro model A1502. It's been working great, but I just updated to Firefox 147.0.4 and I'm seeing an issue that I can't seem to attribute to anything else but the update.

The issue is that when I login to websites... Amazon, Pirate Ship, Venmo, etc... the sites keep saying that I entered the incorrect password or login. I've been using the same login info for a number of months without issue. I even tried to reset and change the password, but they are not recognizing the new password. I've tried different emails... I often have multiple accounts, one for my business and one personal... but they all have the same issue.

Again, these are sites I have been going to regularly for a while, and the issue only recently started after the most recent update.

Thank you. Paras.

Since update yesterday, new tab is empty. Whatever I do, open new tab, open new window, go to `about:newtab` manually, it does not load anything. The view is totally blank. I can navigate to other pages fine as it should though. Only New Tab view is broken. Diagnostic mode does not work. I don't have plugins that would affect New Tab anyways.
