Just updated my MacBook Air to Sequoia 15.7.3. Since that update, Foxfire will open, but when trying to open an article in Foxfire, Foxfire locks up and doesn't wan to shut down even with "force quit." What can I do?

I've used Firefox for 20 years through the various iterations of Windows, and have been using it trouble free on Windows 11 since November 2024. Two days ago, however, When I tried to open the Guardian site (www.theguardian.com) it would open very slowly and not load and of the pictures. This gradually got worse, the site taking for ever to open at all, and always with the little dot in the tab at the top left going from side to side showing it was still loading. I have tried everything I can think of. Opened in troubleshoot mode, changed DNS settings, uninstalled and reinstalled Firefox twice (one time to see if it would work normally if I didn't actually sign in to my account). All to no avail. In fact now things are worse, in that the GOV.Uk website is now giving me similar problems - and a few other sites have become slightly slow and reluctant to open as well. My internet connection seems fine, and all these sites open without any trouble on Microsoft Edge. I am NOT very good at tech, and I am now tearing my heair out as to what I can try next.

Any help wopuld be gratefully received!

Through extensive troubleshooting, I am unable to get firefox to open at all.

I've done a full uninstall, cleaned all user directories, program files / x86, program data, appdata roaming and local, etc. I used the Microsoft uninstaller and even Revo Uninstaller to remove everything related to Firefox, did a restart and reinstall of the latest one and it still won't launch.

Firefox was previously working until a reboot occurred and now it won't launch.

Firefox 32 bit seems to work when installed, and running Firefox as an admin previously worked but no it no longer does.

I looked at the following articles: - https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

There's no malware on this machine (business EDR on it, even disabled it as a test and it still didn't open).

I was able to launch the profile manager but now I am unable to as the processes launch in task manager and then within 5 seconds they close.

Firefox is not running in the background for any user (I'm the only one logged in after a reboot as well)

I'm unable to open in troubleshoot mode either. Tried run as and admin cmd "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode

Ran SFC / scannow / DISM restore health commands as well and both came back fine / no integrity violations

Can someone help please: - I've been trying to buy some tickets for an event in France. When I access the following from Firefox (140.6.0esr (64-bit)) on Debian GNU/Linux 13 (trixie)) the ticketing purchase options don't show. When I access it from Chrome on Android or Edge on Windows it does show. https://www.circuitdesremparts.com/prochaine-edition/billetterie/ It seems I've now missed any Tribune tickets.

Thanks, Tim

Your article about the expiration of Windows 10 says that anyone that has FireFox on the Release Channel doesn't have to worry, that updates will continue to support Windows 10. I don't know what that means (Release Channel). And how can I check if that's what I have?

When I try to log in to my account with Amazon Prime, Firefox freezes as soon as I hit the Continue button after entering the username and password. I can't open or close tabs or do anything. I don't have this problem with the Amazon account in any other browser.

Any ideas why this happens and how to fix it?

My credit card payment methods are missing from Firefox's settings. I tried enabling every relevant setting in about:config and still they won't appear. My current relevant settings are shown in the attached screenshot. any suggestions?

The last 2 days i have had problems signing into my Aliexpress account. The site has told me it is temporarily unavailable, then that the server is taking too long and now that parental controls have been used.

I am 68. I don't need or use my computer for sites that require parental control.

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?

For months I've been trying to clear my saved form data as I put in the wrong email address, and when using saved form data sometimes don't notice it's wrong, so replies disappear into the ether.

Under Settings/Privacy & Security/Clear browsing data I have cleared Everything with all check boxes checked, and multiple times just tried the Saved form info checkbox. The wrong email refuses to die along with the related form data.

It is infuriating. Maybe you can correct it manually, or actually wipe it for me? The INCORRECT email is 'bongoots@yahoo.co.uk'. The CORRECT email is 'bongboots@yahoo.co.uk'.

Many thanks, Bruce Clarke

ive searched every article from here and beyond, but i cannot seem to find the button to edit my payment information. strange since it still prompts to autofill it

I just bought a new computer. How do I sync firefox on my old computer with firefox on my new computer. The same for thunderbird mail. Please help. I am not a computer genius. Dave Muran [edited email and phone# from public community support forum)

A recent update (https://windowsreport.com/firefox-fixes-an-8-year-old-windows-bug-that-broke-virtual-desktop-use/) has broken behavior I previously depended on as part of my workflows: If I clicked a link in one desktop, it would open that link in the browser instance on the last desktop I'd used, so I could keep all my browser windows on one virtual desktop full-screened for easy viewing, then slide back to my other workspaces for messaging/writing/etc.

Now, apparently as a bug fix, every time I try to open a link on a desktop, it creates a new Firefox instance in that desktop instead of opening the link in the browser I have open on other workspaces. This has dramatically impacted how I work. How can I restore the previous behavior? It is so disruptive having new windows opening all the time instead of keeping them in my dedicated browser workspace. If there isn't a fix for this, I will need to move to a new browser.

I started using the new "Profiles" feature in firefox, and I created profiles one one device. However I am finding that the profiles are not syncing across my devices. Both are Windows 11 VMs, I tried doing manual syncs, singed out and back in to both devices. But the Profiles I create on each just do not seem to sync, is this the expected behavior ?
