Upgrading from System 7 PC to windows 11 PC. On new computer (windows 11) downloaded firefox, logged in; Bookmarks transfered, but some sites (AOL.com, for example) auto filling very old password. Old computer auto fills correct password. On new computer, password manager shows correct password. Why is it not working?

I can not remove scenesource from settings and extensions, am doing this to reinstall because the scroll function is not working properly. Appreciate any tech help made easy to understand, I'm old, very old, LOL.

every time i open firefox for pc, a white flash appears very quickly

i tried every thing ai told me to, but still

i cant even record it it doesnt appear in video

I am running Firefox version 153.0.1 on a 64bit install of Windows 11.

A few days ago I had to factory reset my computer, including a clean Windows install. Since then, when attempting to access https://vodafone.cz/muj/prihlaseni, I get an Imperva Error 15 "Access Denied" error screen - screenshot attached here. Clicking the Imperva logo on the bottom of the error message leads to https://www.imperva.com/why-am-i-seeing-this-page/?src=23.

I was able to access the site in the past, most recently on July 8, 2026 - this would have been Firefox version 152.0.5.

This error persists in troubleshooting mode but not in private/anonymous (with or without extensions enabled), nor does it appear in Microsoft Edge or Firefox on Adroid.

Clearing cookies and cache did not help - in fact the error first showed up on a clean install of Firefox, when there weren't any cookies or cache stored yet. I've tried different DNS over HTTPS settings and listing the site as an exception in settings, but none of this made a difference. Enabling Firefox's built in VPN also made no difference, regardless of the selected location.

I found a recent post (https://support.mozilla.org/en-US/questions/1588627) describing a similar issue on a different website and tried the suggestion listed there to try a fresh profile - this seemed to work, but within a couple of minutes of browsing the error message returned. I've even reinstalled Firefox entirely, but this too did not help for long.

Interestingly enough, the error message lists a proxy IP address (not blacked out on the screenshot) despite the fact that I am not using a proxy.

The website provider's tech support claims this is an issue on the user side, not theirs - they have not been able to replicate the issue.

Is there anything I'm missing that would explain why this is happening?

Thanks!

Personally I do not like the new firefox. My bookmarks will not open in a new tab automatically when needed, it over rides the current tab that is opened. Additionally I am constantly being bothered with a unrelated pop up every time I open a new tab. and the Firefox logo used to appear so that you could click on it and get to firefox's home page. New version is horrible. may have to abandon and use another browser.

I downloaded and installed the latest version of Firefox. Every email link in my mail.com email.com account now fails with this message: Error Code: SSL_ERROR_RX_RECORD_TOO_LONG No Firefox setting changes are helping, but if I forward that and other emails with a link to another mail account I have, they links work perfectly fine. So I ave to conclude it is a Firefox issue, but I don;t understand how to fix it. Can anyone advise me, please? [redacted] @writeme.com

I have been using the browser extension feedbro and i really enjoyed being able to plop it out of the main browser window and 'add it to the taskbar' but for a couple days this option disappeared. Is there another way to do this? did "add tab to taskbar" get removed for browser extensions? or is this feedbro related? i am unsure how to test whether the button is missing for other browser extensions as well.

added two images showing that the button is gone from feedbro and still there for other tabs/pages

Windows 11 PC using latest Firefox browser.

Suddenly, today, I can no longer sign in to my usual grocery shopping account, which I have been using without problems for many years. Firefox takes me to the home page but, when I try to sign in, the sign in page just keeps reloading and will not allow me to enter a username or password. I have cleared cache, cookies, and browser data, disabled virus/malware detection, turned off Windows fast start, restarted the PC but it makes no difference. I can sign-in using Chrome with no problem at all.

I had opened a support ticket #447010 with Mozella support and they told me that they can not help me, and sent me here. I am "dead in the water" so to speak. It appears that since Firefox downloaded update 153.0(20260715202819) I have had many issues that appear to be getting worse by the day, and now I cannot open or run my email app. I have not wrote down all the errors (sorry) but here are a couple: 431 Request Header Fields too large, the application is having trouble connecting to the server, unable to load the email from Mozella support. After the update (153.0) my bookmarks have moved to somewhere, the sign on for my email app has changed ( use to click on the firefox icon on the bottom tool bar and the sign in box for optonline.net would be there. I understand that sometimes updates (new and improved) make changes to what users have use to for years. Now is have a browser that is not functional and needs to be corrected, I trust you can help and get this sysem usable again, because right now it is not usable. I presume if and when you respond to me issues it will be at this location and not an email. Please help. Thank you

I'm running Firefox 153.1 64-bit on Windows 11 Pro 25H2. I have a LOT of bookmarks. Possibly over 3,000. Somehow over time I've managed to create a LOT of bookmarks in the Other Bookmarks folder unintentionally. I need to move and merge those to the correct Bookmarks Menu and ideally eliminate any dupes. Everywhere I look for a process to accomplish this I seem to get a lot of "can't be done". Does anyone know how to do this? Thanks for any help.
