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.

This setting, "Always ask you where to save files," is definitely broken.

In a related article, they provided this solution: https://support.mozilla.org/en-US/que.../1534384 https://support.mozilla.org/en-US/questions/1534384]

Proposed solution: "I believe you also need to go into Tools -> Settings -> General and set the Action for the types of downloads (Applications) to Always Ask for those types you want it to."

But this workaround should not be needed. "Always ask" means always ask. As in always. No other additional steps should be needed.

Can you folks please open a bug to get this fixed? This used to work just fine in (much) older versions of Firefox and Netscape. "Always ask" is supposed to mean always ask. Like, always.

quick find, aka shift-7 sucks, not to be mean but when i try to type in my game im making it comes up as quick find, im using scratch and im making a calculator, please help me find out how to de-activate it.

They play for a couple of seconds, then the panel they are playing in goes black. They used to work a month or two ago. Videos play fine in YouTube. They also play fine in apps like VideoPlayer and VLC. They play fine in Chromium based browsers Opera, Brave and Vivaldi. My graphics card requires switching acceleration off. I can’t find a switch for that in Firefox.

Problem Videos start playing, then after a few seconds the video panel turns black. Audio may continue. Refreshing does not help.

Environment

   OS: Fedora Linux 43
   Firefox 147.0.1 (also tested Firefox Flatpak)
   Display server: Wayland and X11 (both tested)
   Hardware acceleration: on and off (tested)
   Media Source Extensions: enabled (disabling MSE triggers an “unsupported device” error)

What works

   BBC News videos play correctly in Chromium-based browsers (Brave, Vivaldi)
   Videos play correctly in mpv/VLC
   Other video sites (e.g., YouTube) play correctly in Firefox

What I’ve tried in Firefox

   Disabling hardware acceleration
   Disabling VA-API
   Disabling WebRender
   Disabling RDD sandbox
   Running Firefox under X11
   Using the Firefox Flatpak build

None of these measures help. This suggests the issue is related to Firefox’s interaction with BBC’s player on Linux. Has anyone else seen this, or is there a known workaround?

Hi,

Since last week I am unable to properly use some websites that are failing due to CORS requests, but they were working before. Some examples are es.webuy.com or a local Jellyfin instance. After trying to enable/disable some settings that I thought could be related to the problem, like security levels, I ended up creating a new profile. In this new profile everything works, but as soon as I synchronize my Mozilla account, then these websites start failing again with CORS requests errors.

Any idea about what setting might it be the one causing problems? Or any idea about how can I debug/troubleshoot it myself?

Thanks!

Hi, I tried to drag and move a tab (worked everytime till now). After I tried to move it toolbar freezed (The image is what I mean by toolbar). Url bar, forward, backward, refresh and 3 lines for settings doesnt work. Only things that works is downloads and side bar. I can also click on tabs and they will open, but moving them wont work. Drag and move options is True.

When I try to quit and reopen firefox, everything works fine until I try to move a tab again. I tried editing the tool bar and default toolbar settings, that wont work either.

FF 147.0.1 (64-bit) Linux mint 22.3

Hi everyone, for some time (~2weeks) I have the issue that I don't get any autofill-information in login screens.

I checked the relevant settings/passwords/"Fill usernames and passwords automatically" (OK) I deleted my ff profile and reinstalled ff. (whereas here it worded briefly) I disabled all plugins (only have "uBlock Origin" running at the moment)

I'm pretty puzzled, does anyone have any ideas? Best, Stefan

My local newspaper has gone only digital, which I actually like. But, there is an option on the bottom of the reader that is available when using Edge and is not available when I use Firefox. A mouseOver on Edge displays "Print or clip". Yes, it's a snipping tool and/or print option. But it really right-sizes the snipped area perfectly for printing crossword puzzles. The Windows snipping tool (Windows 11) makes it too small so I need to go to Edge for only this one task. My first preference would be to get the function on the Firefox screen, and my second choice would be to figure out how to use the Windows snipping tool to print without leaving Firefox. Firefox 147.0.1 (64-bit) The reader if your allowed to open it: https://reader.sl.nj.com/full_page_image/the-star-ledger-2026-01-31-page-42/content.html There are Edge and Firefox screenshots in the attached file. The icon(s) of which I speak is the first of the four on the bottom right of the Edge screenshot ( the first screenshot).

I am trying to access my QNAP NAS configuration page within my home LAN from a newly installed Linux PC with Firefox 147.0.1. Firefox won't let me access the page, popping up an error page:

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to nessy.fritz.box. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

I have verified that the claimed risk is nonexistant, but Firefox does not allow me to bypass the warning. There is no "Proceed anyway" or "Advanced..." button as claimed in various help articles.

How can I convince Firefox that I know what I am doing?

NB: The same page is accessible, also with Firefox 147.0.1, from a Windows PC.

My firefox is not recalling the history as I move through tabs. It doesn't appear in the sidebar or in the documented history. This only has happened recently, and it's still recognizing my bookmarks. I've done some troubleshooting, tried relaunching in the mode while switching through tabs, but it's still not recalling. Any help is appreciated.

Firefox has been crashing regularly for a full day now. I have one profile with multiple extensions, and a fresh profile that is meant to test firefox without any. With this new, "clean-slate" profile with none of my extensions installed, I still get repeated crashes. It is getting in the way of my ability to work- it happens even in Troubleshoot mode, even though I could not confirm any hardware issues prior to this.

Will I need to delete the extenstion-filled profile entirely before going forward? Is there an update I need to install, or anything else I should do myself? Should I provide a list of my extensions?

Attached is the Report ID of my latest crash- hopefully it will help.

Thank you!

I got a message on my Win10 PC saying, "Your Firefox profile can not be loaded. It may be missing or inaccessible."

Mozilla help suggests looking in %APPDATA%\Mozilla\Firefox\Profiles\. I did this but don't know what to do next.

I have another Win10 PC where Mozilla still works, and they do sync. Should I copy some of the Mozilla folders from it to the first PC to restore the problem? Which ones?

BTW, I can still run the Mozilla TOR Browser on the first PC. Thank you!

Hello,

I just installed a new version of Linux Mint (Zara) and all is right with Firefox, except the screenshot who doesn't work. The buttons "Capture the visible area" and "Capture the entire page" don't work. The additional tool in the toolbar doesn't work. What can i do, please? Thanks for your answer. Pierre

I want to achieve windowed functionality of Firefox's F11 fullscreen mode, where there's no window borders nor tab/url bar, which pops in on hover. Having every pixel actually be web space is just preferable to me. This used to be possible in old Firefox versions simply by resizing a fullscreened FF window using a resizer extension or window manager (such as seen here, with version 55.0.3: https://drive.google.com/file/d/1klHdUHiKtLVITmrQnul8O1zF32l-Uz6c/view). At some point, something must have changed in FF's fullscreen API because it no longer responds to any of this.

I'm willing to pay anyone savvy enough to come up with a solution. Ideally by figuring out how to again be able to simply resize F11 windows. Note: "full-screen-api.ignore-widgets" isn't cutting it, there will still be a window border and the tab/url bar won't automatically pop up.

Cheers.

So I have two Google accounts, let's call them Antelope and Bear. Antelope is my "main" account, but I use Bear for a lot of things too, which includes Gemini. So, if I want to use the Gemini chatbot option on Firefox's sidebar, it would make the most sense to use it under my Bear account, since that way I can access my previous chats and all that. However, when I open the Gemini chatbot, it automatically logs me in as Antelope. And when I click on the account's profile picture to swap to Bear, it instead opens the Gemini site on a new tab, in which I am indeed logged in as Bear, but the sidebar remains stuck on the Antelope account. I've tried the "reload Gemini" option, restarting Firefox, and clearing the cache, but nothing works. I think I could fix it by logging out of both accounts, then logging in only as Bear, letting the sidebar "grab" that account, and then logging in as Antelope, but I wanted to know if there's an easier/cleaner way to go about it. Thank you in advance.

Yesterday on Firefox, I discovered that when I Googled questions, the tabs loaded with a blank 2” left margin indented space. See screenshot attached. This occurred after FF update 147.0, and I have Mac Tahoe 26.2. I see from researching this that it’s a problem after the last FF update, as follows:

The left margin indentation glitch in Firefox 147.0 on macOS Tahoe is a known issue, likely related to rendering or graphics settings conflicts within the new macOS version. Potential fixes include disabling hardware acceleration or checking specific feature flags in about:config.

I refreshed FF, and now all bookmarks I had minimized have the 2” blank margin. How do I get it back to normal so that the text has no huge left margin?
