Firefox Community Forum

Hi Team, I am using Linux Mint 20 Cinnamon. Cinnamon version is 4.6.6. The issue is that I was browsing and by mistake I selected one tab then dragged it for sometime and then released the tab but that created a new window and now the old windows are not visible in ALT + Tab function. The windows are showing in the Firefox task manager and also the box icon in the top right corner in that "open tabs". Now I am not able to even change the window or able to access the opened tabs. Attached the screenshot and as you can see in that there are total 4 windows showing in firefox and one as active but in the bottom on the firefox icon you can see its only 1 window. How can I access the remaining 3 windows? Found one ticket (https://support.mozilla.org/en-US/questions/1477845) in this the recommend solution does not work. When I try to click on the window 1 tabs then I do not get any response. I tried both the solution but none worked.

Thanks for the help in advance. @Mozilla team member is seeing please check and fix this bug if possible.

Hello,

Not sure if posted under the right section.

Recently started having an issue trying to sign in to Microsoft Outlook (formally Hotmail) Web. I don't recall any changes i made or updates.

When i try to sign in, it opens a new tab and takes me back to the sign in page. This just continues.

Tried using MS Edge and don't have the issue.

So far tried Safe Mode which disabled add-ons, which are currently Add Block plus, and New Tab Override and the issue remains. Not sure if i tried the refresh option but i think it removes the extensions which is not the end of the world.

Added a few images, one shows duplicate tabs, which will continue

Firefox version 140.0.4 (64-bit)

Any ideas whats going

Thanks

I don't think I chose the right topic, but here goes. With every Firefox update, my bookmarks and everything always seemed to merge into the new update. My computer rebooted with updates today, and I get into Firefox to find that NONE of my bookmarks made it this time.

Everything is empty, and I don't have a backup anywhere because I didn't expect this. Yes, I know - always back up everything but honestly, I haven't had time.

Does anyone know how to fix this? Are my bookmarks hidden somewhere?

I have a lot of stuff for research for writing stored in my bookmarks, and I can't lose them.

Thank you for your help!

Hello support-type people,

I have a specific website that I have active in FireFox called myNoise.net. It allows me to generate background noise generators to cover-up the distracting noises from my neighbours when working at home on my desktop computer. The audio on the website worked the last time I opened Firefox ~2 July ... but today, when I opened the browser, the audio no longer works. I cannot get the website audio to load at all - I added the website to additional exception lists & shut down some content blocking extensions, but no joy. The website was already listed in multiple exception lists & I do not know or understand what change(s) occurred with the browser that would prevent this site from properly functioning - since it literally worked a week ago. I would appreciate any assistance and/or guidance with this issue, otherwise I will be eliminating Firefox as one of my browser options. I have provided a screenshot of the site that shows the perpetual "now loading" screen. Thank you.

(This is copied nearly directly from a post on r/firefox made a few hours ago—I decided it was best to spread it here for more exposure. The only change was the removal of the add-on names from the title due to character limits; these are Form History Control and Text Area Cache.)

I hope the title explains what I am looking for well. My main computer has had... spooky behavior with its file system recently, and I have been recommended to make a back-up, format my drive, and re-install my operating system (possibly upgrading from Windows 10 to 11 in the process). The biggest hold-up to me doing so is this, as I have no idea how to transfer the extension data between installs, or convert it into a human-readable form. The sheer number of writing drafts in those extensions both make losing them an unacceptable situation and copying the data manually into a document entirely impractical. So, can anyone help me with this? For context, I was on Firefox 138.0 when I stopped using my main computer due to those issues. (Note: It will certainly last long enough to do the Firefox Syncing and other back-up operations, just not for many more weeks or months.)

How can I sync my groups between different instances of Firefox (other computer)? That should cover both active and saved groups to have real usefulness. Thank you

Whenever i search something on google, firefox desktop (all fine on android) is failing to display the ai(gemini) answer no matter what questions i ask.

Same happens in the "AI Mode" option that is available in google's recent update.

And, I,m logged in.

This started since a week, everything was working fine before that.

Adding the images below.

Hello all.

I chose "Use Adobe Acrobat Reader" for open PDF in settings and it works fine until I closed Firefox and open it again. The setting bounce to "Open in Firefox". Then, I tried choosing "Always Ask", closing Firefox and opening Firefox again. The setting preserved as "Always Ask" and did not bounce to "Open in Firefox".

I checked handler.json in user profile folder after I chose "Use Adobe Acrobat Reader" for PDF, action is 4: {"defaultHandlersVersion":{},"mimeTypes":{"application/pdf":{"action":4,"extensions":["pdf"],"handlers":[{"name":"AcroRd32.exe","path":"C:\\Program Files (x86)\\Adobe\\Acrobat Reader DC\\Reader\\AcroRd32.exe"}]}},"schemes":{}}

But then after restarting Firefox, it changed to 3: {"defaultHandlersVersion":{},"mimeTypes":{"application/pdf":{"action":3,"extensions":["pdf"],"handlers":[{"name":"AcroRd32.exe","path":"C:\\Program Files (x86)\\Adobe\\Acrobat Reader DC\\Reader\\AcroRd32.exe"}]}},"schemes":{}}

Checked handler.json with "Always ask". Before and after restarting Firefox, action is 1, which is expected and correct.

Some other colleagues reported the same issues as well. I am thinking if this is a bug from Firefox.

Some more notes here:

• The issue only happens to PDF, for other Content types, all good.
• Already disabled all plug-ins and extensions.
• Tried refreshing Firefox in safe mode
• Tried choosing another external PDF reader Foxit
• Firefox version is 140.0.2

Some screenshots are attached showing where it is.

Hope someone can help on it. Thanks in advance.

Hi, I was asked if I could contact you by google disability.

I'm having a huge problem creating a channel on youtube with a live.co.uk account when using NVDA.

I press b until I hear account menu button button submenu, pres enter or space, then arrow down to create channel and press enter. Nothing seams to happen.

Google disability has shown me a couple of video or audio files proving that it can be done, they've even said that they tried creating an account with an outlook account, what live.co.uk is called now from my understanding.

SO I'm really confused as to why they can do it and I can't.

I can't show you with OBS because it messes with my screen readers speech so if you have another way I can show you; please let me know.

I've already tried the following, suggested by disability support: 1. uninstalling and reinstalling firefox.

2. making sure addons are disabled, the only one I left enabled was a volume booster but I doubt that would be the issue.

3. Setting NVDA back to factory settings and disabling all addons.

This has been confusing me on and off for up to a year now.

All of a sudden Firefox started to use alt+number (e.g. alt+3) to switch to that tab (i.e. tab 3 in my example).

Why? How do I disable this? It prevents me from typing any of the special characters that are located on alt + any number key. E.g. I can type the at-sign, not the dollar, or any such character which requires the alt-modifier and a number.

Ok so I usually choose these option to remember history and from time to time delete Browsing & download history and Temporary cached files and pages.

Note: I have "Open previous window and tabs" ticked in general settings which also has a restore previous session option in the history menu. This brings back previous session with tabs etc as is when I close FF. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-51-cf2daf.png

I thought I could automate this on exit but don't think its working right. So I change the option to "use custom settings for history" and tick all three options:

Remember browsing and download history Remember search and form history Clear history when Firefox closes For "Clear history when Firefox closes" I ticked Browsing & download history and Temporary cached files and pages. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-43-b10213.png

The issue is the restore session option is missing and FF opens with all previous tabs gone. I am frankly not even sure what else is missing such as cookies, site data etc. Is this meant to work like so?

From a week ago, for no apparent reason, I get "403 Forbidden" when I try to read articles on seattletimes.com using my prescription to the site. It's a total block of the site.

After rebooting, the site is OK until I log in, as needed to read particular articles. Then nothing is accessible any more.

The trouble is the same on all my laptop/desktop computors, which all have Firefox and are in sync with it, and once I log into the site on one of them it's blocked on all. But this doesn't affect my android phone, on which every article can still be read.

This is clearlly therefore a Firefox problem.  I'm worried that I'll have to switch out of Firefox to some other browser.  This is unreliable behavior.
