Firefox supportforum

Sorry to have this same issue again, knowing full well it can happen after finding this some years ago (https://support.mozilla.org/en-US/questions/1319823), I tried to carefully connect two older PC devices back to firefox sync, however on one I managed to enable sync before disconnecting my profile (it seemed as if reconnecting sync temporarily was the only way to disconnect a profile from firefox's UI - I should have been more careful and removed the profile from the filesystem level): at which point I polluted the sync server.

I've noticed that `about:sync` has an option under bookmarks/engine actions 'wipe bookmarks', which sounds exactly what I need, and if I watch what happens once pressed it does the right thing and repopulates the sever with the 'correct' PC's bookmark set (when run from that PC), however it also says 'other devices will act like a reset', which i'm finding NOT to be the case: eventually one of my other device repollutes the server with bad bookmarks which propogate.

I'm thinking the culprits are my phones, If I wipe and do a sync on a phone, my phone's bookmarks stay polluted. If i'm right about that, I think my question is: can I wipe my profile (or preferably only my bookmarks) from my phones' Firefox without having to entirely uninstall/reinstall (or do you have any other advice for not re-polluting the server from some already-polluted device's bookmarks?

thanks in advance

Is there any way to block media mini players from popping up on websites entirely?

This is what I've tried, I found this in another article here.

   media.autoplay.default = 5 [0:allow;1:blockAudible;5:blockAll]
   media.autoplay.blocking_policy = 2
   media.autoplay.allow-extension-background-pages = false
   media.autoplay.block-event.enabled = true
   media.block-autoplay-until-in-foreground 

It doesn't autoplay anymore, but it still pops up in the bottom right corner of the screen. I don't mean Firefox's picture in picture, I'm talking about the floating mini player most websites use. It's thoroughly annoying, especially when you have your pop-up settings set to off.

Whenever I use the picture in picture feature, it always opens up in a bigger tab instead of the floating PiP. I am unable to adjust the sizing whatsoever. Is there a way to get around that?

I have to configure a lot of networking equipment! One day I might be working on a brand new piece of equipment and the next day trying to log into some ancient piece of equipment because I need to change something and I can't replace it yet. I'm having a major issue with the redirect even if I explicitly type HTTP it forces it to HTTPS ( and no I don't have HTTPS everywhere installed I've actually never used it ). I've noticed recently a few updates back now that if the connection cannot succeed it redirects to HTTP but it can hang up in a weird limbo where it thinks the site doesn't exist. There needs to be a toggle for local addresses explicitly typed "HTTP" to try that first. There also needs a toggle to ignore the security issues when accessing the device with a self assigned certificate as every single networking device has a self assigned a certificate and every time I need to change the setting on a router I have to agree even though I have a greed for the last 10 times when I've access the device or I just reset the device and the self signed certificate changed. And I don't know how you're gonna handle this on mobile but it almost makes using a mobile browser useless because I might as well just get the computer out even if all I have to do is change a password, SSID or just check a setting.

So local addresses need an option to lower the warning level for self signed certificates and to obey the typed protocol!

And there's some sort of bug with the Logic that detects a certificate or non-secure site that breaks when the connection drops. The only way I've been able to get around this is to go to the address bar and hit enter as a reload will not work and a reload skipping cash will not work to bring the site back up.

I've had devices that I thought weren't working only to find out they were working fine after 3 or 4 attempts and restarts only to find it's just that firefox thought the site didn't exist anymore.

And I don't have any other options because chrome is even worse with HTTPS once it gets it's vampire fangs in you're stuck it will not let you go back. And safari you might as will be undead.

Finally getting annoyed enough to write some thing as every time you go change your setting reboot device check setting log back in change saying restart log back in and you have to hit except certificate every single time.

And while I'm here Bring back the checkbox to save/ not save the certificate as I might not want to save the certificate when I know I'm going to reset the device and it's going to be totally different in the next 10 minutes. Or I might not want to save it at all like I go to a website that's misconfigured and the certificates not valid for the domain name that it's using.

BROKEN: Videos automatically play upon landing on a website. I don't want video autoplay. I had that FIXED at one point, but with the new update, all of my settings were discarded, and now I'm back to square one. I do not want video autoplay! Now, on to the next question: many complaints have been lodged on various 'help' pages and forums describing the same problem; my question is, in light of all of these complaints, why hasn't Firefox FIXED this problem and issued an update with the repair patches?! On my version of FF, Mac 126, all video controls in settings have disappeared. WHY? Where did they go? Not that they worked anyway because we had to muck about in about:config with various patches WHICH NO LONGER WORK ON MY MAC! Why is there not a simple ON/OFF switch, in Settings, for those of us who want the choice?! When are FF boffins going to FIX this to our satisfaction, with a WORKING, simple-selectable solution? I await a reply from a knowledgeable Firefox technician, one who preferably works on this part of the browser, please. Help me understand, or make me happy, preferably both.

I'm running the latest version of Firefox (126.0) on an iMac, OS 14.4.1. Starting a couple days ago, i was no longer to (consistently) minimize Firefox browser windows by double-clicking on the browser window title bar. I'm able to minimize the window INCONSISTENTLY and only very infrequently via double-clicking, but with no obvious pattern. This problem only occurs with Firefox. I have no problem minimizing any other browser or application windows.

My Mac OS settings are always set to "Double-click a window's title bar to minimize."

I can minimize via Command-M, but i prefer to double click. I vaguely remember this occurring on another iMac of mine some years ago, but don't remember if i found a fix, or if it went away on its own.

Thanks for any help! dan carlson Belmont, CA

Whenever I browse the web using Mozilla (Google, Startpage or any other browser) AND Mozilla is set to fullscreen mode I get black bars all around website screen which are not present when Mozilla is set to windowed mode.

I am using: Macbook Air M1 (MacOS Monterey 12.6.6.) and latest Mozilla web browser. I have already tried this solution: "go to about:config in the address bar and try changing the value of full-screen-api.macos-native-full-screen to true" and it did not fix the issue. I am experiencing this for a lot of time now and only on my Macbook which means a specific version of Mozilla cannot be blamed. This happens on ALL websites. Note: I did change about:config quite a lot regarding privacy alterations.

I have always been able to use the Mac setting to Double Click Title Bar to Minimize windows and it's always worked fine with Firefox. Until Sonoma, but with a stipulation.

It will not respond at all to a double click, but ONLY when I have chosen to show the title bar in Firefox. It works fine clicking in the tab plane as long as I have Show title bar turned off. This is a bit bizarre, but it appears a recent update of Firefox no longer works like that in Sonoma. Works fine on a Windows 10 machine and on a Mac running an older OS.

Note that I did do all the proper troubleshooting, reset Firefox, start in safe mode and all to no avail. When Show Title Bar is turned on, double click to minimize simply does not work.

When I click on "Bookmark current tab," the small bookmark window opens as usual. But if I then click on "save," nothing happens. The bookmark does not get saved anywhere and the window does not close. Likewise, if I click on "cancel," nothing happens and the window also stays open. Only if I click somewhere outside of the bookmark window does the bookmark get saved and the window close. This has happened only in the current and previous version of Firefox. How can I fix this?

when i fill in a form on a site (example cvs) it will not send and my saved payment information shows when i click into the field but will not stay- i must continually manually fill in my payment information

Is there any way to make Firefox iOS browser Dark Mode a little darker by avoiding the moments when it is loading or reloading a page and the screen is fully bright white?

Getting application errors on some sites – but the same site works in other browsers. This has been happening over the last couple of weeks – getting application errors on some sites but not in other browsers. On the example shown I see the login page flash briefly then replaced by the error.

I have enabled my new Theme but it keeps defaulting back to my old Theme. I have tried closing Firefox and opening new tabs. Opening a new tab also changes it back to the default theme. I have sent an image of the old theme. The new theme is Aurora Australis. And the second image shows this Theme enabled. What gives? Carl

Hi there,

I read books using Amazon Kindle's cloud log in. After installing Firefox 126, I am no longer able to open books on my last page, I cannot turn pages or even open my notes. I tried using Kindle cloud on other browsers and everything works fine.

Any idea why my Kindle cloud functions are not working on Firefox?

I am migrating to a new laptop. The new laptop keeps asking me for a primary password. I have never set one up. This issue doesn't happen on the old machine, only the new one. It also won't let me disable the pop-up that asks for the primary password. Please advise.

once every week or two, private browsing shows up in history. it is not cleared when i close all private windows. the rest of the time it works as it's supposed to. any suggestions are welcome. thank you. running 125.0.3 on mac ventura 13.6.6
