My spell check generally doesn't work, but occasionally comes back to life, I have tried the about config, and change value to 2, I have tried uploading dictionary, and making sure check as I type is ticked, but the setting on config seems to keep reverting to 1, and I'm sure if I have successfully uploaded a dictionary, I clicked on language pack, Ironically while I'm typing this, my spell check is actively involved.

I have a MBP running OS Sierra (10.12.6).

I've exported all my bookmarks & Passwords ready to import them later.

I've downloaded the extended 115.40 version of Firefox. I've deleted the 'old' versin of Firefox and opened the esr and I see the bookmarks are still there... so what did I do wrong?

I'm still getting the 'This browser version is no longer supported' Error

Thanks g

115.40.0esr on Mac OS High Sierra v. 10.13.6

When attempting to enter log in information automatically, the expected notification appears and is confirmed, but the "Logins & Passwords" repository remains empty.

When attempting to enter log in info manually, from the "Logins & Passwords"page, the error message "an error occurred while trying to save this password" pops up after filling the fields under "Create New Login" and hitting the "Save" button.

I know I'm working on borrowed time with this setup, but I'd like to squeeze as much life as I can out of this old Mac, and having a functioning password manager is high priority.

I get the following error message when trying to access Microsoft Outlook.

Something went wrong server Error(/): GetSections returned no conversation history

I've already 1) restarted the computer, 2) cleared my cookies and cache, 3) re-started firefox in troubleshoot mode, 4) reinstalled firefox... none of those fixed the problem.

On Thursday 3rd September 2026 Firefox stopped working. I tried lots of things to get it to work to no avail. Today, 8th September 2026, I had already deleted the Firefox that was already on my PC so I downloaded a fresh copy from the Firefox website and installed it. It ran perfectly for about 30 minutes then I shut it down. 5 Minutes later, a Firefox crash report appeared which I duly sent of. Checking Event Manager a string of error messages saying the same thing, Its the XUL.DLL file that keep crashing! This was the same file that caused the failure last week. I had made sure that XUL.DLL was not on the pc when I downloaded Firefox today. When I click on the Firefox icon it open but stays on a black lower half of the screen and boxes at the top, white lined but black and transparent lines moving left to right across them, eventually it fails and closes, after a few minutes it send the crash report. Its a shame because I have used Firefox for many, many years and now having to use Edge!!!!

I downloaded and installed Firefox. I've set up an account. But nowhere does it show me, or tell me, how to "open" Firefox and start browsing. There is no "search bar/window", just the address window at the top. I'm getting close to deleting the whole thing because it is needlessly frustrating.

I've noticed that Mozilla products (firefox, thunderbird etc) all phone home all the time, which is a violation of both my security as well as privacy policy. In the firewall one can observe persistent, periodic, repeated connections to various non-sanctioned sites and services, apparently run by Mozilla. These include, but are not limited to:

• .mozgcp.net
• .services.mozilla.net

firefox-portal-detection.com etc.

Specifically, there are persistent, periodic and repeated connection attempts to (just copy/pasting from the first page of firewall report; there are many more as well as similar connection attempts from thunderbird as well): firefox-settings-attachments.cdn.mozilla.net:443 assets-prod.sumo.prod.webservices.mozgcp.net:443 content-signature-2.cdn.mozilla.net:443 push.services.mozilla.com:443 etc

These begin at the startup of the browser/mua and continue throughout the session. Given that none of the sites actually browsed have anything to do with mozilla per se, and given that various privacy-violating features such as DNS-over-HTTPS (yes, that's a not a privacy-enhancing feature but the opposite - it just shifts the surveillance point from the ISP to the DoH provider) and other similar "features" are disabled in-browser, there should be no user/browser connections attempted to mozilla servers.

Also, by setting up a local security MITM proxy in order to observe and analyze the content sent to and received from these services and configuring the browser to connect via the proxy, the browser seems to *stop* trying to connect to these services, which indicates *active* measures by the browser/mua to avoid it's browser-fingerprinting and location-revealing content from being intercepted and analyzed.

This is especially concerning as Mozilla actively brands and markets it's products as privacy-respecting, as for-user-rights and as away-from-big-tech-dominated. Consequently I perceive this as complete breach of trust. Even by just *attempting* such phone-home connections a leak of metadata occurs, identifying the IP, the browser and consequently the user and user's location, sometimes actively (such as was the case with now apparently discontinued location.services.mozilla.net). Combined with whatever content these connections carry, this constitutes a serious breach. And there seems to be no way for the user to configure the browser to stop making these connections, other than by using an external application firewall.

And to top it off, with Firefox version 155.0.1, the browser now outright refuses to connect to *any* sites at all if firefox.settings.services.mozilla.com:443, firefox-settings-attachments.cdn.mozilla.net:443, firefox-portal-detection.com:80 and content-signature-2.cdn.mozilla.net:443 are *externally* blocked, at least on that profile (which worked just fine prior to upgrade to 155.0.1), showing a spinner and waiting indefinitely (not even timing out). These are the *only* connections it even attempts, completely ignoring the actual site that it was told to connect to. So that's at least 4 privacy-violating, security-policy-violating phoning-home connection attempts and a complete disregard for user's actual, sanctioned connection request.

It says to drag and drop but that does not work. I minimized both windows and dragged the one tab to the 'larger' window and nothing happens. My email keeps opening in a new window and it never did before. It was a tab in my original window, and now it is so much harder for me to work.

Well, I am in a real mess. Three days ago I lost the ability to access my favourite website. I CAN access the website in the Brave browser. The website owner has told me that it is not a problem with my account with them so it must be a Firefox issue. Before this happened I had been trying to move and delete files on my laptop and have got very confused about EVERYTHING. In that I had deleted my Firefox recovery folder(s). I have managed to move them back into my Home folder before they expire. Now I am being asked to enter my "password" to initiate the restore. But the several Firefox passwords in my laptop are not being accepted. How can I get a new password? If that is not possible do I have to delete my Firefox account? What is my best way to recover from this mess? Any advice is greatly appreciated.

bei Ebay werden die angebote falsch angezeigt, zum bespiel kann ich nicht sehen da eis ein Preisvorschlag ist. nach löschen der cookies auf der seite ist die ansicht richtig und wenn ich mich eingeloogt habe ist wieder alles falsch, echt nervig.

I'm not super familiar with Firefox VPN as I don't use it often but I was using it for a Canadian page earlier and then all of a sudden it stopped working and I can't access it anymore. What's going on?

Hello, I have formatted my laptop and downloaded firfox, but I'm not able to restore my old bookmarks and passwords after I signed in to my account and sync. Could you help me with this and thank you.
