FINALLY got my zorin os to update, and now also have the newest version of firefox uploaded and working. My singlefile addon works properly, I have upgraded to the newest versions of my video downloaders, and I have cleared my history, but my 2 video downloaders still don't recognize any videos on youtube. Any suggestions or alternative downloaders?

I have Firefox 136.0.2 (up to date) on Win 11. I want to remove specific autofill items, NOT all autofill items. Web info says use Settings > Privacy & Security > Forms & Autofill BUT there is nothing for Forms and Autofill in my Firefox 136.0.2

Can anyone please help me find how to edit autofill in this version?

Recently clicked to update to the next version of Firefox. Then I get the message "Restart to Update Firefox." I restart Firefox but the message is still there when I click Help > About Firefox. It would appear that the update did not happen for some reason. Do I need to re-install Firefox to get around this problem?

Hello. This question concerns the Windows 11 desktop version of Firefox.

I have long used the Home and End keys on my extended keyboard to scroll to the very top of any given page in Firefox (Home) or to the very bottom of that page (End).

But, lately, I notice that, for no reason I can figure out, Firefox no longer responds to those shortcuts. Now, when I tap Home or End, the page may, at first, scroll up or down slightly but not to the top or bottom. If I press Home or End again, nothing happens at all.

Sometimes, if I press Ctrl + Home simultaneously or Ctrl + End the page will scroll to the top or bottom respectively.

Why has Firefox's behavior apparently changed? Is there an issue with my keyboard or operating system settings? (I use a Logitech G915 keyboard.)

Please let me know how to restore Firefox's shortcut functionality, where I can tap just Home to scroll to the top of a page or only End to scroll to the bottom of a page.

Thanks and be well.

Trying to browse ebay using Firefox. The pages have become really slow when loading.When scrolling down the page is blank then slowly populates as I scroll down the page. I've just tried microsoft edge and there is no problem.

I'm using Firefox v136.0 on a Windows 11 host.

Each time I open Firefox the software prompts me two times (via a dialog) to enter the primary password. (I previously enabled and defined a primary password.) I'm also prompted twice to enter the primary password when I open the Firefox's SETTINGS page. This happens in "regular" and SAFE mode. I do not have any extensions installed nor themes installed/enabled. The only plugins that are installed are "OpenH264 Video Codec provided by Cisco Systems, Inc." and "Widevine Content Decryption Module provided by Google Inc."

When I delete the primary password, the browser does not prompt me to enter the primary password on startup or when opening the SETTINGS page.

FWIW, I've tried the following sequence, but the problem persists:

1. Uninstall Firefox
2. Delete as many temporary files as I can in $HOME\AppData\Local\Tmp\
3. Delete $HOME\AppData\Local\Mozilla\
4. Delete $HOME\AppData\Roaming\Mozilla\
5. Reboot
6. Reinstall Firefox
7. Open Firefox and add a primary password
8. Close and reopen Firefox

When I reopen Firefox, it prompts me twice to enter my primary password. When I open Firefox's SETTINGS, I am prompted twice to enter the primary password.

Any suggestions as to how I can convince Firefox to not prompt me twice for the primary password when opening the browser would be appreciated.

in settings Homepage and new windows use custom urls, current urls doesn't include Pinned tabs. Windows updated and when firefox was restored two windows were opened, one was blank and the other opened old home page settings but did not reopen all my pinned tabs, gmail, yahoo mail,and some other tabs I plnned, there are 5 of them and several regular tabs I had open before and most of them did not show up in history. Pinned tabs do not get included in use custom urls for the home pages. Also for several days my roboform bar would not show up, roboform said no open browers to attach to when firefox was open.

According to Firefox Help, "After you have defined and set your Primary Password, you will be prompted to enter it once for each Firefox session, when Firefox needs access to your stored passwords." But since updating to version 136.0 I get asked for my Primary Password even to see my home page. Why is this?

Ever since I updated last week, one website that I use will not work. Whenever I try to log in to the M&T Online Banking website, it blocks me and says "M&T Online Banking Is Temporarily Unavailable." The app works on my phone and I can log in through Chrome, it's only on Firefox that I'm getting this problem. I called M&T Bank and they confirmed that it's a problem with Firefox. Something is blocking me but I don't know what it is. I am not using a VPN or adblocker.

Since the settings haven't given that option for years, the best way to have a local file as the new tab page was using autoconfig.cfg + autoconfig.js, as described in this thread: https://support.mozilla.org/en-US/questions/1251199 But since the most recent update (v136.0), this stopped working.

The New Tab Override add-on has its own issues with using local files (can only load a .html file, no local CSS/JS, can't give a blank address bar for me to search in), so it doesn't solve the issue either.

This is very important to me, and others have been asking for this feature back for years. It feels awful to have the working solution stop working, in the browser that's supposed to be open and customizable.

Hi, I've been using DuckDuckGo as a search engine for several years. Yesterday, I entered my search terms as usual, and all it showed me was a blank screen. Even searches that I did weeks ago simply come up blank. (see screenshot) When I searched in Google, it completed just fine. The same when I switched browsers (Chrome and Safari). This must be connected to a recent update either in Firefox or DuckDuckGo, but I can't seem to find information on how to fix it. Thanks for your help.

The Vanguard website warns me that my Firefox browser "is no longer supported" and must be updated. when I try to update, the message is "Firefox is being updated by another instance." what does "another instance" mean? how can I update it? fyi I run Windows 11 on my desktop.

In Firefox, it's possible to store logins, and then assign a Master Password to protect those stored logins.

In the newest version of Firefox desktop for Windows (136.0 - 64 bit) - it asks for the Master Password twice, even when only showing a blank start tab.

Normally, it will first asks for the Master Password, when you browse to a website, that has a stored login. Is it a bug or a new security feature?? - anyway, I find it very, very annoying.

Firefox Desktop (x64) worked normally until the version 135 update was installed. Now tabs (even a single tab) crash after startup unless Firefox is run in troubleshooting mode or Windows 8 compatibility mode. OS is Windows 10 Pro (x64) 22H2 on ThinkPad E495 (AMD Ryzen 5 3500U) Things that haven't resolved the problem: - Remove extensions and themes - Refresh Firefox - Reinstall Firefox - Updating Visual C++ 2015-2022 with Redistributable (x64) version 14.42.34438 - Updating Firefox to version 135.0.1 and subsequently to version 136.0, however updater only works in Windows 8 compatibility mode - Full system scan for malware (none found) Note: Extensions NoScript and Cookie AutoDelete work normally with Firefox running in Windows 8 compatibility mode.

Hello,

My university requires me to logon to use campus services every 24 hours. Upon expiration of the logon credential after the 24 hour period, a logon window will prompt to re-enter credentials. The problem is that it will continue to prompt log in with new pop up windows every few minutes so if I don't log in, for example, over night, I'll wake up to hundreds of log on window pop ups. This creates system wide slowdown due to memory resources being maxed out. I can't enable universal pop up blocks as the systems I require use pop ups and having to open each pop up manually does work in my workflow. Any solutions? Thank you!

Duck Duck Go search from the address bar suddenly does not work. All queries return a page with the search box and no results. Google search functions correctly. Additionally, the search function on Yahoo Finance no longer functions. Both of these websites and functions work on a mobile version of Firefox connected to the same wifi. At first I had no idea what was causing it but after using troubleshooting mode and turning on extensions one at a time it turns out that metamask was causing the error.

My Firefox browser has been crashing for a while now (Years). It's fine playing YouTube and BBC iPlayer but when I advance the time marker to a different part of the stream or video, it crashes. It also has a problem when playing slots. It seems to crash a lot making it impossible to play.

I have tried using Firefox in Troubleshooting Mode but the same things happen.

Here's the crash report ID

Many thanks in anticipation and I hope someone can help me fix these issues.

None of my saved passwords in my Mozilla account are showing up when I switch laptops and try to logon to various sites. Instead I have to manually enter the passwords for the sites every time even though the sites show that I have saved passwords for that site in my Mozilla account. When I type the password in a old or new site, Mozilla doesn't even ask if I want to save the password anymore.
