Hello! A site kept popping up a confirmation window for an action I was trying to take, and in the confirmation window, there was a checkbox for something like "don't allow [this website] to prompt me again" (that's as best I can remember). I checked the box thinking it would just allow the action to happen without the confirmation window, but instead, the site just won't take that action anymore. How can I undo this setting? Thank you!

Hello,

I have the site espn.com bookmarked and for the last month or so it has been opening it's various foreign sites instead of the united states version when I click on the bookmark tab. It will switch to the UK and Mexico sites randomly when I click on the tab. The address is saved as the US version (espn.com) when this happens so I can't figure out why it's doing it. It doesn't matter if I use a vpn that says I'm in the US or just my regular internet provider in the US, the site keeps changing what country it chooses to open with. I noticed that every time I click the tab it will cycle between the various different sites for each country even though as I said before, the bookmark is set for espn.com. It makes no sense as none of my other bookmarks do this and it doesn't do it when I use Safari's browser. Is there anything on my end I can do to get this to stop or is it coming from espn.com's end? Thank you for your time and help. :)

Getting error SSL_ERROR_BAD_CERT_DOMAIN on all my sites that are signed with a SSL Cert from my internal CA since updating past version 99

This appears to be a bug starting after Firefox version 99 on Windows because after i upgraded to Firefox version 100 i started getting this on all my SSL Certs from my CA and they worked fine prior to the update. Can anyone confirm if something changed after version 100 that is causing this?

Thank you.

Hello.

I have two profiles, for separating work and personal tabs/bookmarks/etc. I wanted to update Firefox from 95.0 to 95.0.1 but in both profiles I saw "Firefox is being updated by another instance" in the About Firefox dialog when both were running. So I closed one of them and the other offered me the usual button to update immediately. I did it, restarted that Firefox instance/profile, which restarted normally, but now the second one does not open. Instead, I get the error transcribed above in the subject (see attached screenshot).

So my question is: please, how do I regain access to my second profile without losing that profile's data?

After today's update to version 98 Firefox keeps saving files to the Downloads folder when I don't want it to, I just want to open them, but not keep them, with this new behaviour the Downloads folder keeps filing up with useless clutter.

For example, before the update, when I downloaded a .zip file, a pop-up would show up asking if I wanted to save the file or open it with an application. If I chose to save it it would be saved to the Downloads folder, and if I chose to open it nothing would be saved to the Downloads folder.

After the update, when I download a .zip file, Firefox always saves the file to the Downloads folder, even if I choose to open it.

Can you please tell me if there is a way to make Firefox behave like in the previous version?

Hello, since migrating from Chrome to Firefox, I have used the Import Wizard to successfully transfer over my bookmarks and history, but I just can't seem to get my logins/passwords over. The wizard finishes saying that it successfully imported saved logins and passwords, but nothing shows up in the password manager. I am running Windows 10 64bit and Firefox is up to date. Anybody have any suggestions?

Thanks

How do you remove The Firefox Title bar from my desktop? It prevents me from clicking the "Accept or Decline" buttons for example on software installs for example. on your support page I tried the "firefox menu> + customize & disable the title bar through the button in the bottom left corner of the window". There is no "customize" option.

I was watching anime today on some site and my firefox was downloading many files without my knowledge into my download folder. I'm worried that it can be some viruses? This is a screenshoot. Should i be worried? Thank you for help.

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

Please help, I just screwed up so bad I accidentally pressed the red "close" button on Firefox on my Mac instead of the yellow "minimise" button and lost a bunch of tabs I need (they were from a while back so not in history)

There is no option to "restore previous session" or "reopen tabs" is there any way whatsoever to recover my lost tabs I am freaking out big time there was some really important stuff in there that I hadn't bookmarked yet like an absolute IDIOT!!! My session had stayed active through computer being shut down and restarted and Firefox updates but pressing the red "close" button has seemingly nuked it. Is there a way to go into folders and find the tabs? Anything please help :(

Any help appreciated, I'm desperate.

When I am watching a TV stream on my PC; when I hover on (some) pictures or videos, a supremely annoying pop-up url appears at the bottom of my screen. I have some learning problems and can not figure out the 'userChrome.css' method. I can not work with long streams of multiple overlapping instruction. I am not tech savvy. I do not understand 'layers' and stuff like that. I can do the 'about:config' thing, if anyone knows whether or not if I can fix it from there, I would be eternally grateful. Thanks.

Immediately on update to 96.0 this afternoon, multiple sites failed to load - Google(Maps, News etc), Yahoo, Flightradar24 etc - others partially loaded - then sat there blank. Explanation of errors is NOT clear -

Is it possible to revert to previous version? Everything seems to work fine when using EDGE!

Hello,

I've just downloaded firefox, making the switch from chrome. Doing so I've migrated a couple of tabs and extensions I had. Totally it was 50 tabs, with 6 extensions, I've downgraded now with the switch and it's only 37 tabs and 2 extensions, even so firefox is using more ram than google by a large amount. With 50 tabs open, chrome was using 1.5gigabytes of memory. With the same 37 tabs and extensions, firefox is currently using 6 gigabytes of memory.

The tabs used are from reputable sources, so firefox shouldn't be breaking on these websites. The extensions I am using at the moment on firefox is, Ublock origin, Dark Reader.

As far as reputation goes, firefox should be using less Ram than chrome. Is there a setting I should know about to lower such performance issues? Firefox acceleration is ON.

Thank you for any answers.

Hello. I and a friend of mine are having trouble with firefox, it seems to be using excessive ammounts of ram as pictured. I only had two tabs open and two addons installed when I took that screenshot. Any help would be appreciated, thanks in advance.

Hello How to remove extension symbol from toolbar? ^(see image): https://i.imgur.com/2bh8se5.png Any idea? Thanks

How do I create a TLS 1.0, 1.1 exception in Firefox 100.0+ for my legacy devices (NAS), that no longer get firmware updates from the manufacture, that are on my private network and thier configuration is done through a web browser?

 I have been using Firefox browser for a long time, since it was called Mozilla browser.  An answer such as "I'm out of luck." means I will have to look for a new browser.  I prefer not to do that.  I trust the Mozilla brand and like you products and recommend them to my friends and customers.

Hello, I have been using Firefox as my main browser for more than a decade. One could say i am some Mozilla fanboy, having convinced many of my friends and relatives to use Firefox instead of any chrome based options (Which there are to many these days). It struck me today, as i was reworking some workflow elements in many programs i use daily, that it is impossible to change any key binding in Firefox anymore. I know it has been a while now, and i searched all over the web for an answer or a solution, but at this point it is clear that other than going in the code and recompiling Firefox manually, it is not possible. I stumbled upon the (only) extension that allows to change some shortcuts, but the two that i wanted to change are impossible to configure from it, being disabling only f12 as i would use it for other things but i do not want to lose the dev console and also ctrl+L to open the address bar, it is quite inconvenient and would much prefer to use ctrl+spacebar as it matches many other bindings i am using with other software. There have been many other features that were changed in the recent years that made me start to look for an alternative, as i see features melting away almost as quickly as the user base of the product.

I do understand that one person's problem is not going to change the way a big piece of software is working, but i am wondering, why are the users losing such features as basic as customizing key bindings in a piece of software that used to be so incredibly customizable in the past? Why is the only viable option to anything chrome based losing it's edge over the competition? Is Firefox v150 be based on the chromium engine or will it die before?

Thank you in advance, and no, i don't need the link to the shortcut page, i already have it.

Hello!

I have been using this userChrome.css code to hide the tab bar if there is only one tab (on Windows):

tab:only-of-type, tab:only-of-type + #tabs-newtab-button {

   display: none !important;

}

#tabbrowser-tabs, #tabbrowser-arrowscrollbox, #tabbrowser-tabs > .tabbrowser-arrowscrollbox {
   min-height: 0 !important;

}

Since one of the recent Firefox updates, this code does no longer work. Maybe because there is a new element in the tab bar: A drop-down list at the right.

Any idea how to make the above code work again?

I am running El Capitan and need Firefox 78. I went to a site offering 78 as a download, and version 91.5 came down. Site offering 78esr, same thing. Went to https://ftp.mozilla.org/pub/firefox/releases/ and was unable to figure out how to download 78. Clicking on 78.0 just led to more links that got me nowhere. Is it possible to download version 78 from this or any site? Thank you. heaton5
