I have been using 1Password 7 to manage my login credentials. It includes a Firefox extension to fill in account names and passwords in login alerts and pages.

Firefox 147.0.1 (macOS aarch64) in January 2026 has broken 1Password 7's ability to fill in account names and passwords.

To reproduce: 1. Install 1Password 7 Version 7.9.11 (70911000) and its extension version 4.7.5.90 in Firefox 147.0.1 on macOS. 2. Visit a URL for which 1Password 7 has login credentials. 3. Click on the toolbar icon for 1Password 7. A 1Password 7 dialogue box pops down from the icon, containing the username and password for that URL. 4. Click the Autofill button in that dialogue box.

Observed behaviour: 1. Username and Password fields remain blank.

Expected behaviour: 1. Username and Password from 1Password 7 appear in the Username and Password fields.

For approximately the last three months, there was a partial failure similar to this. 1. 1Password 7 popdown dialogue moves from the toolbar icon to the Firefox tab for that URL. 2. Username and Password fields remain blank. 3. Workaround: click in the username field, then tab 2-4 times to further UI objects in the login credentials form. Then click the 1Password toolbar icon, then click the Autofill button in the popdown dialogue. Then, the Username and Password from 1Password 7 appear in the Username and Password fields.

The expected behaviour occurs for the same URLs in Safari.

Thus I suspect that Firefox has somehow changed its behaviour in the last few months to cause this regression. I have not changed the 1Password software versions in this time, because I am intentionally using a previous version of 1Password.

I am looking for a fix or workaround which works with my current 1Password software version. I am not interested in a solution which requires me to upgrade to the current version of 1Password. (The current version of 1Password imposes a feature which I am resisting.) I realise that this reduces the chance that I can persuade the Firefox team to find and correct this regression.

Anyway, Im Trying To Print An Email Message To a PDF File But Instead I Get An Error Message That Says :

Could Not Open The File Access Is Denied!

Is There A Way To Fix This? If So How Do i Fix This?

This problem just started with the latest version of Firefox that opens with two profiles. It worked for a short time and then failed. Firefox will not open if I choose the default profile. I can open Firefox if I choose Profile #2, but it has none of the history of the default profile. I lose all of my extensions, history, bookmarks - everything.

How can I get back to where I was yesterday? (Note: I'm just a user, not a computer geek, and don't understand the buzzwords or technospeak. I can follow clear instructions like copy, delete, rename, etc.)

I'm using an HP laptop with Windows 11.

I am using version 147.0.1 (don't know when last update) For the last 1.5 hrs I have been trying to restore the extensions icons as well as other, to the tool bar. when I close "customize" after putting them there they disappear, as does the "puzzle" piece I put up there. What is going on? I have read numerous articles on how to fix this to no avail. Only one character will stay to the right of the added search bar.

When attempting install firefox on linux using the recommended install method (in order to use 1password fully i cannot install it via snap) the priority does not change from 500 to 1000 using the parameters described in the install guide. Here is an image showing my issue.

I went to youtube account of Jack Storm Jack Storms | The Glass Sculptor - YouTube; I tapped on his "website" and the next thing I know are the at least 3 side messages regarding a virus. I have attached one photo of said message.

this is another: https://berht-shv.com/zclkvisitor/9a3fb513-fa41-11f0-acfd-12edde5c536d/85aefdc2-9ed0-48aa-922d-60f9f9fc0f2d?campaignid=9a50f321-fa41-11f0-acfd-12edde5c536d

Please direct me as to next moves. I did put on strict.

My geeksquad agent dumped me here. They were not able to fix the issue. My tools are not all on the bar, my book marks are not all here. They got some. There was a message that some other application was using my firefox and my tools and bookmarks wouldn't work. I am no tech person. I just want things back like they were and to know why this happened and I don't want it to happen again. Please help.

Hi,

I am not a tech savy person. My firefox crashed on my laptop. Now all my book marks are gone. But the book marks are there on my iPhone. Can somebody please please help me to restore?

When printing puzzles from USA Today on my Canon Maxify, the crossword puzzle and the sudoku both show up as two pages, when they are only one each. If I don't change the setting from All to Current each time, it will print a blank page with each puzzle. This just started happening within the last month or two, but I have had Firefox/Duck Duck Go for many years. If I switch my browser and search engine to Google, which I hate, it shows and prints each puzzle properly. I don't know if it's the browser or the search engine, but it is a problem that I didn't have until recently. The print box is completely different from Firefox/Duck Duck Go to Google, so if it is Duck Duck Go that sets the printing box, I need to contact them. Firefox version 147.0 on Windows 10 on Lenovo laptop. Thanks in advance to anyone with a solution.

I accidentally messed it up when trying to remove the desktop icon because I already set Firefox in my taskbar. Now I get an unfamiliar screen and my settings, including bookmarks, are gone. Is it possible to set my laptop to undo changes made today?

I have two machines running Windows 10 and Firefox 64 bit (synchronised and up-to-date). I recently noticed that the desktop is missing several Firefox bookmark folders, which contain hundreds of bookmarks.

How do I get the desktop fully synchronised with the laptop? Do I use backup? If I am to use backup, how do I see what is in backup, so that I know it is backimg up correctly? Do I reinstall the Firefox and import from backup?

Ich habe seit einiger Zeit Probleme mit unterschiedlichen Login Masken die nicht korrekt angezeigt werden.

Z.B. Online Banking, Synology NAS, etc. Ich habe Firefox jetzt schon drei Mal neu installiert, dann geht es gefühlt ein paar Tage, jetzt kann ich mich nicht mehr auf meiner Synology NAS anmelden, weil die Login Seite nicht angezeigt wird. Verwende ich z.B. EDGE funktioniert es einwandfrei!!

Igend eine Idee ?

Mit freundlichen Grüßen

Moderator note: This question has been edited to remove an unintended link.

On Chrome, web push notifications show the full origin (e.g. pl2.forgeofempires.com), but on Firefox only the notification text is visible, without the website address. Is this a Firefox limitation by design, or is there any way to enable showing the full origin in notifications?

I've been annoyed recently to see the Firefox symbol on both my Desktop and in the taskbar and finding that there are two in the taskbar when I open one. The bottom line is that I seem to have completely obliterated Firefox as I'd had it set up! Can I restore my Firefox settings to where they were yesterday?

www.russellmoccasin.com won't load properly on any browser on my macbook pro running Mac OS 15.7.3. I don't have any browser extensions running, I've cleared my browser history, cookies, and cache. Still won't work. When I disabled javascript on safari and firefox, the website loaded perfectly. But I have to have JS running to use almost every other website on the internet, so what gives??

New laptop. Installed Firefox. Set up 2 of the "new" type profiles. Typical extensions (Bitwarden, Bit.ly, Firefox Color). Not too long after, Firefox will no longer launch and the only remediation I've found is to do a clean uninstall/reinstall including deleting registry keys. I've now done this three times now. Environment information

• i7 Core Ultra/32GB RAM
• SentinelOne - Corporate Environment. Installs Firefox Extension. There are no signs in the S1 portal or client that it is blocking firefox.
• nVIDIA RTX PRO 500 Blackwell Video Card. Updated to current driver 582.16
• Threatlocker - Computer is new and has been in "Learning Mode" so it isn't an issue
• Tailscale runs on this machine, but it doesn't seem to make a difference if it is running.

Nothing in the %APPDATA% crash reports folder for firefox. Crash dumps for firefox are in %LOCALAPPDATA%/CrashDumps. One read by AppCrashView is attached. It is a 0xc0000005 Access violation in StackHash_2264.

This is a problem where renaming the firefox.exe to firefox1.exe will get it to run but it seems to lose track of profiles.

Firefox is my favorite browser and I'd like to resolve this, but I really can't afford spending much more time on it or continually clean reinstalling and rebuilding profies. I've seen other similar posts, but no clear resolution.
