Firefox Support Forum

Hello, I am using Firefox on a new computer, and I have a bizarre problem that I never experienced on other computers. The 'recently closed tabs' and 'recently closed windows' options are disabled. They are grey, and I can't click them (see image). Also, the 'reopen closed tab' when you right-click one of the tabs is disabled (grey). I have tried to search everywhere why it can happen and found nothing. Any advice on how to enable this option? Thanks

Everytime I load Firefox the bookmarks sidebar is not shown.

Navigating thus View => Sidebar => Bookmarks I can bring it up. It will stay visible for the whole of my browser session. However, after I've closed this session and started another. the bookmark sidebar is missing again.

How can I make the bookmarks sidr be available all the time?

FF 127.0.2 OS Windows 11 Pro v 24H2 Build(26100.994).

As of today, DirecTV is no longer supporting Firefox for watching live streaming. They show the attached image. Brave works, too, btw (Chromium-based browser). Do you know why this is happening? Has Mozilla been in talks with DirecTV about this? I use this feature every day.

When I logged onto Firefox this morning it asked me to update which I did. When I got onto Firefox all my tabs were gone. Please tell me if I did something to cause this and how to keep this from happening again. I do have it set up to restore tabs when logged off and starting up again. Also please tell me how to get my tabs back! I tried to follow instructions for this but actually didn't have the things they said to click on. Thanks so much for your help!!

When trying to login to my AT&T account from fire fox the page continually refreshes and will not load. Microsoft edge will login fine. Anyone know the solution?

Hello everyone, I have had a problem for a few weeks on the X platform. Some buttons no longer appear, notably the edit button on an image post or the "see" button for a hidden account (see images attached) Does anyone have a solution? I uninstalled ALL the extensions and restarted the app, but nothing works! Thanks in advance

Firefox : 127.0.1 (64 bits) Mac mini M1 2020, mac osx Sonoma 14.4

After auto update this error message came up and will not allow Firefox to open. Earlier in the day it had also updated ( not sure to what version) and was working fine. Laptop was then shut down and turned off for aprox. 1 hr. I then turned it back on and tried to open Firefox and it again asked to allow Firefox to make changes to my computer to which I clicked Yes. It then would not open and this error came up. error message Platform version 127.0.2 is not compatible with minVersion >=127.0.1 maxVersion <= 127.0.1

I need to create a pdf file to share with an agency in another country that does not have Firefox. I am unable to create a simple pdf - all of the files are automatically Firefox pdfs. All attempts to convert this file to a regular pdf have failed. Please help!

This is a repeat of a problem that I posted a couple of weeks ago. I am unable to log in to my New York Times account on Firefox (other browsers work fine). I have reset the password several times but it still doesn't work. I had a response to my previous question that led me to disable Total Cookie Prevention for that site. Thereafter the Times seemed to work properly and I stated that the problem was fixed. However, the fix lasted for only a short time and it is again acting the way it previously acted--I can't get past the first page to the full stories. There must be something else at work, but I have no idea what.

This issue is only on two computers (24" iMac running Sonoma) - others at the client site work normally.

Client has up to date Firefox (127.0.2 - also tried latest ESR) full screen with multiple tabs - config set to use system print dialog by default. Print - print dialog opens, print is sent. Tabs are now greyed out, cannot type in text boxes. Changing context (opening and closing About Firefox) restores normal function.

set up a new profile - same issue.

Any suggestions?

I installed a dev version of Firefox to test a plugin.

Then I uninstalled the dev version, but now none of my profiles on the regular version work...

Please help me, I really need my old browser history and cookies.

When I try to use one of my old profiles, I get "You've launched an older version of Firefox" and it tells me to either Create New Profile or Exit.

I read online that people add "-allow-downgrade" to the Windows shortcut, but this does nothing for me.

Thanks you and please help!

Since downloading latest update, requested by the software, it takes 2 or 3 times longer to go to most websites, but it takes 10 times longer to go to a Youtube video. (Generally 10 to 30 seconds).

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

Starting with Firefox version 120, you can set Firefox to automatically launch whenever you start or restart your Windows computer. https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer

The browser shows opt-in prompt for the user to easily setup this behavior. However, I do not want to do this.

When I click "No thanks", the prompt goes away, but couple days later, it returns. I guess that an update resets the prompt status.

Is there a way to permanently disable this opt-in prompt without allowing Firefox to start automatically with the computer?

Hi,

am running firefox 127.0.1 on a windows 11 desktop. Numerous sites that use a captcha to login fail. In other words, the captcha never loads and I cannot login to those sites. Such sites include teamfaderpro, Coursera, and bandcamp. All logins fail as the captcha is required to be passed prior to logging in, but the captcha never appears and so when I try to log in, nothing happens and I cannot login.

I have tried the above same sites on the Edge browser and have no such issue, the captcha shows and I can login.

Just FYI, the agent switcher setting change recommended by others previously is not suitable. When I tried that fix I was unable to access a considerable percentage of the internet due to some cloudflare issue, so the agent switcher setting is not an option. So far, I have tried all recommended settings to fix this issue and nothing has worked.

I am surprised no one else is having this issue.

Any help is appreciated, or at least inform google/mozilla about this issue as it has been ongoing (on and off) for me for many months. And yes, this problem is persistent for me at the moment, it remains despite rebooting windows, despite clearing cookies and cache (which I have set to automatically delete when exiting firefox).
