When I click on my Firefox web browser, I can open one window and one window only. The + sign allowing me to open and keep open multiple windows at the same time is gone. For instance, when I open my email, that works fine, but if an email contains a link to a news story I want to read and I click on it, the browser takes me there, but it closes my email window and I can't get back to it, unless I close Firefox and start over.

How can I load group of tabs I have a previously saved? I checked the article about tab groups: https://mzl.la/4iQYJr3

I'm using the vertical tab bar. I cannot find the List All Tabs toolbar icon shown in parentheses. Thanks for the help.

Hey, I am currently working on an application where I want to upload files to a server using mtls via a webapp. The upload goes to another url and server than the one where the webapp is served from. If I test the file uploading without mTLS, it succeeds, and with mTLS enabled it also works in chromium, but in Firefox I get the following error: "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at <url> (Reason: CORS request did not succeed). Status code: (null)." on the `OPTIONS` request before the `PUT` is done. The client and the server both have a certificate from a custom CA, which I imported into firefox, along with the private key. Does someone know what the issue here might be? I am suspecting that there is some problem with firefox loading the user certificate on the preflight request?

When I started my browser today, my history and bookmarks were gone. When I try to restore them from the backup file, I cannot click on any buttons in the Manage Bookmarks folder. The buttons are entirely unresponsive.

I clicked on the Google icon and got a screen that said "Gak, that site just crashed" Has been happening periodically with other links. If I restart the computer the problem disappears so I can ask you for help Thanks

Does Firefox still support automatically updating the opensearch XML description? MDN still mentions this feature: https://developer.mozilla.org/en-US/docs/Web/XML/Guides/OpenSearch#supporting_automatic_updates_for_opensearch_description

Also, in about:config, there used to be an "browser.search.update.interval" entry that specified the update interval. I can't find it anymore.

If this isn’t the right place to ask, could you point me in the right direction?

I've blocked access to nearby devices without knowing that this would affect my local network websites. Now the option to change this on the settings simply does not appear for me. What can I do?

Hello, on my local disk I have Firefox for Windows (10) installed for more than 2 years now, and the location: %Appdata%\Roaming\Mozilla\Firefox\Profiles\xxxxxxxx.deault-release\storage\to-be-removed has more than 7000 subfolders and files that sums up to 4GB of data, dating from mid 2023.

I naturally assume that a "to-be-removed" named folder should have it's content removed by some automated task or maintenance service, right? Is this normal, or is there some bug in application maintenance / updating process?

Thank you

I recently experienced [not previously] in trying to print a received e-mail using the "print" item. When I clicked on the "print" word I received the following error

https://mail.yahoo.com/print/message/AFe0zTKlUhih9Gu_uzKg3tJ-XbE?appName=NOVATION_APP sent back an error.

Error code: 403 Forbidden

   Check to make sure you’ve typed the website address correctly.

Please advise how/where I may change a setting to avoid this error

I get n error report when I try and access the seagate login page. This was not a problem a couple of days ago. The error report says 'You have not selected this website for SSO'.

I cannot find any help to resolve this problem and it is slightly odd that it was an accepted site previously.

Many thanks for your help Paul

When switching tabs using the MRU menu (Ctrl+Tab), it only shows 7 of the most recent tabs. However, oftentimes I need to jump back further down in the history. This history *is* kept in the Firefox View tab. Is there any way I can extend the number of recent tabs shown in the Ctrl+Tab menu?

Or at least in the "List All Tabs"? It currently is set to show the tabs in natural order and not MRU.

OK, I am a heavy user of tab groups in Firefox (glad to get off Chrome once this was available). Unfortunately, Bookmark All Tabs only saves the open tabs in my Firefox window. It Does Not save anything inside a tab group that isn't opened - AND it doesn't save any of the tab group structure - ex. the group, what is inside it, etc.

IS there some way to properly save all the tab information (groups and tabs inside those groups) in Firefox? There is in Chrome by the way. IF there isn't, has someone out there produced an extension to do this??

Seems like a big oversight in the intro of tab groups if there is really no way to do this...

I do the Bookmark All Tabs for backup and have needed it many times in my Chrome past usage.

Thanks in advance

Just updated to 144.0.2 (aarch64) on my MacMB Pro running Sequoia 15.7.1 with no other changes and now I can't play any YouTube videos, whether embedded in a website or YT directly. Get eithger a black screen or white, such as below. What arcane setting do I have to mess with now to get this back to normal? (OK in Safari.)

Log onto Firefox. Go to Yahoo mail, log off this and yahoo homepage shows daily pop up which is some sort of counter ("Don't ghost us" day 1,2,3, on on Google says this is a browser issue, Redirect to Chrome same thing. Have adblock on. All settings on all 3 browers do not stop it

Every time I log in with my Firefox account on a new device, the exceptions I set under Privacy & Security -> Cookies and Site Data -> Clear Cookies and Site Data When Firefox Closes -> Manage Exceptions disappear. This should definitely be included in synchronization. Let's be clear: I don't want my cookies saved so I can log into all my accounts every time. I just want my exceptions to be included in synchronization. Firefox could also develop a tool for this: an add-on to easily add websites to exceptions. I don't want to download an external add-on and install it every time for something this simple. Nobody wants that. I also think all my settings should be included in the synchronization scope.

Just now will not save a page to bookmark folder, even in trouble shoot mode. Know how to save. See pages in recently closed pages, but do not know what is the cause. Should I refresh, tried close and reboot system. Let me know some steps to analyze the cause and remove it. Thanks, but don't under stand the method to ge Troubleshooting Information.

Hi everyone, I’m using multiple Firefox profiles to separate my work environments (e.g., “Work”, “University”, “Personal”), all linked to the same Firefox account.

What I would like to do is:

Use the same Firefox account across multiple profiles to keep extensions, passwords, etc., synchronized.

Sync bookmarks only within the same profile, so that bookmarks from the “Work” profile do not appear in the “University” profile and vice versa.

Continue to be able to edit bookmarks from different devices (home or office) while keeping them synced only within the same profile.

I’ve looked into Firefox settings and sync options, but it seems Firefox syncs everything across all profiles connected to the same account.

My questions:

Is there a native way or any setting to have bookmarks synced separately per profile while using the same account?

If this is not possible at the moment, could this be considered as a potential feature for the future?

Thanks for any suggestions or guidance!
