I've set up a second profile to keep my personal and work browsing separate. When I reopen my non-default profile, it doesn't restore the previous session's tabs. I have "open previous windows and tabs" checked under Settings > General > startup in both profiles. Please advise.

When logging into an account there are multiple usernames (incorrect or older.) I would like to remove or delete them, but keep the current passwords.

Is that possible without deleting the account?

Thank you, rldelahay

I have recently refreshed Firefox on my laptop running MacOS. Previously I had changed the full-screen-transition in about:config to be zero, but since refreshing changing the setting hasn't disabled the transition. My config is this currently: full-screen-api.transition-duration.enter 0 0 full-screen-api.transition-duration.leave 0 0 full-screen-api.transition.timeout 0 Despite everything being like before the transition persists... I'm currently on the latest version of Firefox (125.0.3)

So on my macbook when I enable fullscreen the anmation is super weird. first it stretches the video to the top and then just expands to the whole screen, when I go out of fullscreen is stretches to the bottom and then goes out off fullscreen. for example on safari it just expands the video until it takes up the whole screen. I have gone in about:config and disabled the fullscreen animation but that did nothing.

A couple of months ago, I suddenly lost all my saved bookmarks, plus the ones on my toolbar. Strange thing is, all the folders and sub-folders I created are still there, they're just all empty.

Can I get them back somehow? I've been collecting them for years so can't replace them all!

Why aren't pull-down menus, behaving consistently, on Firefox on an M1-Max Mac on macOS Sonoma ?

The pulldown-menus don't persist, long-enough to click-upon a selection .

There are a few websites (e.g., https://thehermitagehotel.com/) that show up as a white screen (see attached) when I visit them from Firefox using my usual settings, but show up correctly if I use Firefox in private browsing mode. Turning off enhanced tracking protection does not resolve the problem. My browser privacy in Settings is set to "Custom" with everything checked, but changing to Standard and reloading the site does not fix the issue. As I noted above, the only thing that works is to open the site in private browsing mode. Most sites work fine. This problem is limited to 2-3 websites. My version of Firefox is 125.0.1 .

Hi there. I love Firefox, but I have an issue at the moment where I have one copy set up on my Mac, and it has two profiles. However, I'm running into regular problems where they're both open and they can't quit, or they crash, or they want updates, the other one, and then it has to be restarted and can't open web pages for stuff like that.

A little bit more about my setup. I have two admin accounts on my Mac and an applications folder with Firefox in it. Then each of my Mac accounts has a version of Firefox with a different profile.

I'm about to do a clean install of macOS with the two admin accounts. I want to install Firefox correctly this time. How do I have two entirely separate copies of Firefox running on my Mac in the two admin accounts? I just don't want their threads to be mixed or them to be updating each other or anything like that.

Absolutely love Firefox, but this has been quite a big issue for me and I'd love some advice here. Thank you.

Additional note, I followed the link below the first time I setup to create two profiles, but that didn't quite do what I wanted.

How can I get access to my own site again? I have been able to access joycefitch.com for years but today I can no longer access it from Firefox.

We have used Firefox for access to certain sites for years. Recently, we wanted access to particular sites, but the info boxes needed would now not allow entries. Then, we went to Chrome and there was no problem entering the info. Please provide a response to resolve these issues of Firefox not allowing data entry, but Chrome allowing data entry for the same sites.

At one time, I was able to swipe left on my trackpad and go back to the previous page on firefox. I can't seem to find where to set that preference. I'm running MacOS.

Every once in a while, maybe once or twice a week, I'll press Cmd+L to highlight the address bar, type a URL for a new website, and press enter, and instead of going to that new website Firefox just reloads the current page. It seems that this happens exclusively when the current website is gmail.com. (I might be wrong) I can't remember it happening on any other website. This problem has been occurring for me for the past year at least. Any recommendations?

After Firefox updates itself, the restarted browser session is unresponsive to mouse clicks - can't follow links, can't respond to UI dialog boxes, the browser is unusable for practical purposes. It's fixed after another manual restart. This unfortunately breaks all the streamlining Firefox has done to restore the session after an update, because none of that stuff works the same after a manual quit and restart. This is happening on MacOS, and it happens across multiple computers.

Ever since the latest update, the picture-in-picture function stopped working properly. If I activate it, the video will automatically go to full screen, and I need to press the full screen button multiple times to move it down to a small box. I am using Firefox on a Mac laptop.

hi guys, i want to change my default favicons but i cant find this path on my mac.

Firefox is not permitting videos from YouTube that other browsers easily play. This needs to be fixed. YouTube offers their Premium subscribers videos which can be played at a higher bitrate, which means even 1080p can play at a higher quality. When setting quality on a video, in addition to the 1080p, you can choose "1080p Advanced bitrate" as an option. Firefox has trouble playing these files, whereas Safari and other browsers don't have a problem with YouTube. Please fix this.

Whenever I go to youtube, it fails to work and leaves an error in the console similar to

Uncaught Error: Constructing ytd-app: [Exception... "File error: Corrupted" nsresult: "0x8052000b (NS_ERROR_FILE_CORRUPTED)" location: "JS frame :: https://www.youtube.com/s/desktop/050e6796/jsbin/desktop_polymer_enable_poly_si.vflset/desktop_polymer_enable_poly_si.js :: kCb :: line 9877" data: no]

I've determined that I can fix the problem by deleting my Firefox profile. I'd prefer to avoid this since there's a lot of useful history there. Is there a more targeted fix the problem I'm seeing?
