So, I've had this problem since last 3 months. I'm using Firefox with auto-update turned on. Right now my version is 110.0.

Every now and then Firefox stops to load any websites and after closing it and opening it again it won't open correctly saying that my profile was created using newer version of Firefox and I need to create new one. At some point I was on default-release-9 until I asked about it on Reddit and got a reply guiding me to check compatibility.ini in my profile directory and fair enough, when this happens, compatibility.ini indicates Firefox version 119 so Firefox is right thinking that values don't match.

But the definitive question is how do I stop Firefox from messing around with that file? I'm honestly tired of manually editing it every time Firefox stops working. I know that website loading problems can stem from my excessive uptimes but this is an issue I can work around by restarting Firefox from time to time.

Hello,

I recently purchased a VPN for my laptop. I bought a designated IP address set to Toronto, Canada. However, Firefox shows my location in Japan.

In my communications with VPN server they believe since whatsmyipaddress shows me where my VPN says it should, but FF shows me in Japan, the problem may be a leak at your end. When I created this account today and set my country to Canada (as suggested by PIA), closed everything and rebooted my computer I had hoped to see Canada (en) when I began a search. However, it still shows Japan.

I value my privacy on all devices and turning off location is the first thing I do. I'm now wondering if FF is getting this location from Windows.

Any assistance is most appreciated. Thank you,

All images, webm, gif etc. are loading, seemingly, exactly 20% upscaled compared to the real resolution of the media. I'm using a 4k TV (S95B), but I have desktop scaling at 100%, and browser scaling at 100%. I don't believe it's a GPU or OS system wide type setting because windows photo viewer gets pictures right. I'm using ShareX to measure the pixels of pictures. I can even load a local picture in a tab, and it will be upscaled beyond its native resolution. I have no idea why. I've tried a bunch of things, like setting layout.css.devPixelsPerPx to 1.0, which did nothing. I've reset Firefox to no avail, and I have noticed that Chrome is doing the same thing, which would usually indicate it could be the OS or GPU driver, but again, other apps load images perfectly normally. Do apps have categories on Windows now, where something like a "browser" can be told to treat media files differently than other media handling categories? I'm really lost at this point, nothing seems to work.

Hello,

I have a firefox Account "accountA" which has the primary eMail-Address "mailA". I had an other Account "accountB" with primary eMail-Address "mailB" and secondary eMail-Address "mailC". Sadly I lost access to "accountB" and it's primary Mail-Address "mailB" (which is ok) but want to change the Mail from "accountA" to "mailC".

However, this is not possible since "mailC" is locked to "accountB" which I can no longer access (since I need the primary Mail Address. This meens I can never again use "mailC" for my Firefox account, which is now my primary Mail-Address. Is there should be a way to disconnect a Mail-Address from an account, if one has ownership of this Mail-Address?

This is my second email to you....

I just switched to Firefox from Chrome, because Chrome was crashing all the time.

All I want to do is sync my computer, laptop, phone and Ipad's reading list. I want to be able to see an article on one device, add to the reading list, and have it on all devices.

I'm logged in under the same name on all, and it says sync is on, but the reading lists are different.

Can someone help me? My phone number is [removed phone# from public support forum], email is [removed email from public].

Thank you!

Hi @all,

I reinstalled my computer from scratch with Windows 11, before this reinstallation I had Windows 10. Now I noticed that with the newest Firefox version 109 (that I also had before with Windows 10) and Windows 11 my multirow bookmarks toolbar doesn´t work anymore. Before the reinstallation it worked with the following code:


/* Source file https://github.com/MrOtherGuy/firefox-csshacks/tree/master/chrome/multi-row_bookmarks.css made available under Mozilla Public License v. 2.0
See the above repository for updates as well as full license text. */

/* Makes bookmarks toolbar span multiple rows */

#PersonalToolbar{
  --multirow-bmb-n-rows: 3; /* Control how many rows are shown before scrolling */
  --multirow-bmb-row-margin: 2px; /* Control how much spacing is between rows */
  max-height: none !important;
}

#PlacesToolbar > hbox{ 
  display: block;
  width: 100vw;
}

#PlacesToolbarItems{
  display: flex;
  flex-wrap: wrap;
  /* --uc-bm-padding is defined in autohide_bookmarks_toolbar.css */
  max-height: calc(var(--multirow-bmb-n-rows) * (5px + 1em + (2 * (var(--multirow-bmb-row-margin) + var(--uc-bm-padding,2px))))) !important;
  overflow-y:auto;
  scrollbar-color: var(--lwt-accent-color) var(--toolbar-bgcolor) ;
  scrollbar-width: thin;
}

/* Hide the all-bookmarks button */
#PlacesChevron{ display: none }

/* Add some spacing between rows */
#PlacesToolbarItems > .bookmark-item{ margin: var(--multirow-bmb-row-margin) 3px !important;  }


I already tried some other codes that I found in the internet but none of them worked. I have this code in the file userChrome.css, this file is in a chrome folder and this folder is in my profile folder. Can anybody tell me what I have to do to make the multirow bookmarks toolbar working again?

Hi,

I'm wondering if anyone can help me here. I use Google Fi to make and receive calls from my browser. I accidentally denied microphone permissions to Google Fi from the Firefox dropdown prompt and I cannot find how to get it back.

When I click the dropdown menu, I see no options to enable or disable permissions. I also do not see anything listed in the Security settings of the browser. When I check the google fi settings, I see it complaining about denied permissions though.

I've attached screenshots. Does anyone know where I can revoke the blocked permissions?

Thanks,

Hi, I'm a big fan of dark mode and avoiding bright screens. When Chrome begins to load an image slowly, generally it has a transparent background. Is there a way to remove this white loading screen in Firefox and make it transparent, or at least make it black or something? Having a big white block show up on screen is bad for your eyes. Thanks.
