I am having two problems, both related to downloading files only on Firefox, these issues don't occur on other browsers when downloading the same files.

The first issue is that when downloading a file from Google Drive, the download always fails. It opens up a menu asking me where to save the file but the files name is "download" with no extension, when starting the download it will fail. In the images below you can see what it looks like. This happens with most files on Google Drive, usually those larger than 50MB (a VERY rough estimate). Both in the default tab and in the container tabs I use.

The second issue is very similar, when downloading a file, this time from anywhere on the web, when asking me where to save the file, the name of the download is a string of random letters and numbers with no extension. When starting the download it fails because the name is too long, after renaming it to something shorter it still fails. I don't really have any sites I can give as examples because this problem only occurs randomly.

For both problems I have tried attaching the correct filename and extension but it still fails.

Today I started getting repeated notifications, every 5 to 10 min or so, that my McAfee subscription has expired, my credit card has been rejected, and that my computer is infected. I do not use McAfee, either in Firefox or on my computer. I use the security suite that comes with Windows. I cannot stop these messages from appearing, and disabling notifications from McAfee in the messages does no good, the notifications just keep coming. HOW DO I MAKE THEM GO AWAY? They must be SPAM because I've never had a McAfee product on this machine, EVER. Thank you so much for the help, Dave Templeton

Over the past week or so, Youtube videos take a while to start, and will at times just stop and buffer. I turned off uBlock Origin for Youtube, and I have Youtube Premium, but this issue is still happening. Ookla speed test is 569.32 Mbps download, and 23.50 Mbps upload. My Firefox is set to automatically update. Current version is 127.0.1

Dear all,

For some time now my Firefox browser is crashing while I use it. Then a loop starts where a window appear with buttons offering to Restart or Close Firefox but whichever I choose it takes several sets of open/crash to stabilize when in the end if offers to either open it again, or refresh Firefox. I don't wan to refresh because I have tens of tabs that I want to save. But I can't because OneTab, along with all other extensions, is being disabled after the restarts.

I have a crash ID of one of the latest occurrences of this phenomena: f6ef62ad-b072-46b8-8bc8-0d3ca0240708

Please advise!

Hey guys,

I saw in the following post that I can modify the zoom values of Firefox to custom values of my choosing (e.g. 75%, 85%):

https://support.mozilla.org/en-US/questions/1201469

I followed the instructions but it did not work for me. Yes, I did save the changes I made, and I completely closed & reopened Firefox, but the changes I made have not been applied for some reason. Please see the attached image.

I would have ask the question in the aforementioned thread but it's been archived so I had to open a new one. Does anyone know why Firefox does not seem to recognize my custom values (.75, .85)? Thanks!

Hi there! After a short elektricity blackout my PC was rebooted and I lost functionality of shortcuts on Mozilla default home page, turning on or off this shortcuts leads nowhere and just move search bar.

I am using Linux Mint with Firefox 127.0.2 (64-Bit)

In Preferences Applications, setting

 CSV-Dokument      to    open with firefox

opens edless new firefox Tabs - so I had to kill firefox. (setting CSV-Dokument to open with OpenOffice works fine. But this is not what I want.)

In Preferences Applications, I found further CSV types: application/csv-Typ CSV Document (application/text) CSV Document (octet/stream) CSV Document (application/x-download) Which applications should I use for them ?

I found the file "mimeTypes.rdf". However, I am not familiar with the syntax.

I had to do a new install of Windows 11 and logged back into Firefox and can't find my old bookmarks. I got to this point and don't know how to retrieve old bookmarks:

C:\Windows.old\Users\meljo\AppData\Roaming\Mozilla\Firefox\Profiles Please help me.

Thanks Mel

I am using Firefox 127 on Ubuntu.

When I press the Control key, I often lose focus in the window I am currently viewing. This is annoying as it prevents me from copy-pasting for example.

Sometimes the focus is back when I release Control, sometimes it is lost and I have to click again on the text field. It does not happen on all websites, for example support.mozilla.org works well, but it happens on duckduckgo or overleaf.

It does not seem to be the same as existing issues such as [the "show mouse when press Ctrl" of Ubuntu] (it is disabled) or an addon (the problem still happens in safe mode).

In case it is useful, when I press Control the tab bar background goes slightly darker, see attached images.

Thanks for your help :) Nicolas

all of a sudden when I log on to hotmail dot com I get the error message too many requests when I switch browsers to edge I can log on to hotmail as normal

searched the internet but so far have not found a fix

windows 11 and firefox both up to date

In Firefox, after a reboot, how can I re-open my previous sessions?

Originally I had quite a lot of open browsers & tabs. Then I needed to do a reboot, and now I've lost those previous sessions.

Usually I just open Firefox, and this opens one browser, and then all of my previous browser, and tabs reopen, but this time Firefox crashed, and its popup said it needed to restart, but it would re-open my previous browser and tabs, but it didn't.

After following the usual Firefox help guides, it still wouldn't re-open my previous sessions. Now if I ask it to open my previous sessions, it just opens the recent help guides, and not anything before the crash.

So is there a backup file of my missing sessions that I can roll back to?

My computer (Windows 11) crashed while I was using Firefox--for the first time that I've seen, it did a full disk check. When booting back up, I was unable to use Firefox, since it said that my profiles.ini file was lost/corrupted.

After renaming the old file, I went back to the folder. It was easy enough to reinstall the add-ons that I needed, but I'm trying to get my bookmarks back. However, I can't seem to find them--the "bookmarkbackups" folders that come up are too new, and only one (the current one) has a file in it.

Any help will be appreciated! I'm not sure what I can do.

I have a Yahoo email account and Firefox has the saved password for it. I've changed the password for my Yahoo email account recently. When Firefox prompted me if I want to update the saved password I must have chosen "NO", I don't remember. I stayed logged in the Yahoo email account for a few days after I've changed the password. I've logged out of the Yahoo account. Now I can't log back in because I don't remember the new password I've created.

I'm wondering if Firefox has the new Yahoo email account password saved somewhere in its cache.

OS: Windows 10. Firefox: 127.0.2 (64-bit).

I'm trying to get my Firefox installation to permanently disable private browsing mode, however, all information I can find is for the Snap version of Firefox, and not for the Flatpak version. How do I disable private browsing on my installation?

When I search for a Hebrew-language video on Firefox the resulting link text overlaps with the English text “Translate this page” for all YouTube videos. I don’t want any page translated and my Firefox Translation settings include no languages. The overlap only occurs on YouTube video links. How can I get rid of the “Translate this page” text? Thanks.

after creating a new profile, and copying everything in the root directory to the new profile, including search.json.mozlz4, the default search engine setting does not get transferred over and is still set to google

I do not have any ad blockers and have disabled "Block pop-up windows" in Firefox and turned off "Enhanced Tracking Protection" for sites but I still get the message that I am blocking ads.

I have an issue with Firefox 127 not accepting a session cookie that I use for user authentication. I have an ASP.NET application with a login form that includes fields for login and password, and a submit button. When the button is clicked, an HTTPS/POST request is sent to the server. The server responds and sends back a session cookie named .Cookie.Name with the parameter httpOnly set to true.

When I check in Firefox's Developer Tools under the Network tab, I can see .Cookie.Name in the server response. However, in the Developer Tools under the Storage tab, .Cookie.Name is missing, which prevents the user from logging in. This problem does not occur in other browsers like Chrome or Edge, nor does it occur in Firefox version 126. The configurations for Firefox 126 and 127 are identical.

Could you please assist with this issue?

For a long time I've used Firefox on Linux with multiple instances each with their own profile folder. Today when I try to run these instances with separate profile folders I get the following error:

> Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile.

Profiles are created like this:

firefox --new-instance --createprofile "PROFILENAME ~/.firefox-PROFILENAME"

They are run like this:

firefox --new-instance --profile "~/.firefox-PROFILENAME"

It seems something has broken with the instance isolation as this is now throwing an error. Additionally I run "createprofile" it doesn't seem to actually create the folder.
