When I go into fullscreen on firefox macos, hovering near the top shows the traffic lights (fullscreen, minimize, close window buttons) and moves everything down. This may be expected behavior, but it is very annoying as when you try to open new tabs the tab bar moves out of the way of the traffic lights, and the traffic lights area is around the size of the tab bar. Is there any way to make the traffic lights always visible or keep them from moving?

Firefox is downloading files directly to my Downloads folder instead of asking despite having turned on every setting that says it should ask first. Under about:preferences I have turned on "Always ask you where to save files" under Downloads, and I have set Applications to "Ask whether to open or save files". I have even gone in to about:config and turned off "browser.download.useDownloadDir", but the files are still going directly to my default folder.

I have a General Motors account that I can't login to. https://www.gmccanada.ca/en/ownercenter/service They recently changed to multi authentication using Microsoft. I can login to the first step but after I enter the sent password in the second step nothing happens. I have tried basic some trouble shooting like Firefox trouble mode, clearing cache and adding web site to exceptions in settings. GM Help Line told me to use a different browser!!!

Hello. Since a few years I was using 2 FF instances. Profile1 (default) triggered by "C:\Program Files\Mozilla Firefox\firefox.exe" Profile2 triggered by "C:\Program Files\Mozilla Firefox\firefox1.exe" -P Mike -no-remote -no-deelevate I could start profile 2, than profile 1 and corresponding icons on Windows 7 taskbar were lit.

Out of the blue today when I start profile2 shortcut icon from profile1 is lit and I can't start profile 1. When I start Profile1 I can run also Profile2 and corresponding icons on taskbar are lit.

There were no hardware nor software changes on that PC. How to get back possibility to run 2 instances of FF? Mike

Please, how can I disable the tab title on hover? After they appear, they stay on the screen even if I switch windows and are extremely annoying. (Work on fedora, gnome)

I'm using Windows 7 and have been migrated to the esr updates for Firefox. I think this problem started cropping up just before going to the esr versions, but not sure. Firefox will a) randomly hang and do nothing for 5-10 minutes and then pick up fine b) tends to hang a lot when signing into websites like banks, etc, doing the same thing as (a). I've updated FF several times since then, but same problem. I did try to do 1 fix which suggested creating a new "places" database, but that did not solve the problem. Not sure where to go from here as nothing has changed on my computer since the problem started - no new software, etc.

My community association uses Constant Contact for its documents, notices, etc. When I get an email message from them, it often contains several links beginning with https://r20.rs6.net. When I try to access one of those links, Firefox tells me "Hmm. We’re having trouble finding that site. We can’t connect to the server at r20.rs6.net." Chrome and Edge do not give the same error - they can access the requested page. Is there some setting in Firefox that I need to change to fix this problem? Firefox has been my default browser for years, but I also like to read notices from my community association.

This morning when I exited firefox and then tried to bring it up again (windows10) I got an error message

Error Platform version 118.0.1 is not compatible with

       MinVersion >= 118.0
       MaxVersion >= 118.0

I have a lot of of Important Book Marks and don't have the bookmarks backed up any where.

I don't remember updating Firefox this morning but could have.

How do I fix and at the same time retain my bookmarks an other information from 118.0 I have a different version an older version Firefox installed on my computer (115.0.2) which I only use for google voice - I am using this installation to ask this question.

Thanks,

I try to set up Firefox Sync on Firefox on a VM on Fedora. I enter my e-mail and password. Then I get the message (after retrying): "Email resent. Add accounts@firefox.com to your contacts to ensure a smooth delivery." However, I do not get the email with the confirmation code.

My email address has this format j@xxxxx.org

When I'm trying to go to a specific website, it doesn't connect with an error code "SEC_ERROR_UNKNOWN_ISSUER". I was able to press a button labeled "Accept the Risk and Continue" before, but the button seems to have disappeared?

When writing reviews in Google Maps when you click post pictures from your computer (allowing one to browse your computer to find pictures to post) the tab crashes.

This occurs on other websites as well where one would browse the computer to attach documents, photos or videos. Heck, it even happens with this site (selecting browse to post picture causes firefox to crash).

This did not occur prior to updating to 115.0

Windows 11 operating system

Hello. I recently moved from windows to Linux Mint, and noticed the behavior of the Picture in Picture window is different when resizing. On windows, the aspect ratio is kept. while on Linux, it is free form, making these black bars around the video, so I have to resize it very carefully to not show any black bars.

How can I make the PiP on Linux behave like on Windows? That means resizing keeping the aspect ratio.

Attached are the comparisons between Windows and Linux Mint.

Thank you very much!

hello! i've been having an issue with mozilla where webp images are not loading at all. this is especially prevalent on youtube, where thumbnails simply do not load, as well as on tumblr, where if an image or gif is a webp file, it will refuse to load. both are attached in the image below to see the difference between firefox and chrome, as the images load fine on chrome. as well as that, discord, when opened with browser instead of the app, does not load profile pictures, server icons, or custom emojis. google hadn't helped me at all, and i don't know what to do at this point. i don't want to go back to using chrome.

in the attached image, the top images show a set of shark sculptures. the first does not load on mozilla, and looking at the image file, it is a webp. the second image is revealed to be a jpg, which mozilla treats normally. in the second set of images, there's a quick look at a random youtuber's page, the top being mozilla and the bottom being chrome, and you can see the mozilla thumbnails do not load.

thank you for reading! i'm very confused and am unsure what to do. any help is appreciated!

HI! I posted earlier about problems accessing websites after updating the browser to 115.2.0 esr. Earlier in the day I had accessed these websites with no problems .... now after the update installed, shopify is trying to validate whether I am a human and verify the browser. Resulting in an endless loop of identifying myself as a human and it trying to validate the browser.

Ever since I update Firefox a month or so ago, every time I open the browser it wants to restore my last session. I've went into setting and check it to make sure I did have it on. I even turn it on, rebooted and the took it off and rebooted. Nothing seams to work. Any help?

I have Windows 11 with high contrast mode enabled and I have tried all the settings, to check in registry, in the theme file itself (.theme) and in the settings of Fiferox. Could you please suggest what else can be done?

Reposting from https://discourse.mozilla.org/t/firefox-upgrade-from-115-116-results-in-broken-screen-capture/121964

Howdy folks!

I am on Arch Linux and recently upgraded Firefox from 115 to 116 and this broke WebRTC screen capture. Whenever I try to share my screen in Microsoft teams and Google Meet, the participants only see a black screen with a cursor. I am able to reproduce the issue on this test page. I had to downgrade to 115 in order to “fix” this critical feature. Before that it was broken in 114 and I had to use Chromium for presentations. I no longer want to touch Chrome with a 100 ft pole since they are trying to introduce Web Environment Integrity.

The only bug I have been able to find is from three years ago:

https://bugzilla.mozilla.org/show_bug.cgi?id=1640771

I don’t want to add a “me too” comment, but was wondering how to show/give my support to get this issue fixed? It is crippling to my work workflow, and I don’t want to be on 115 forever. I am an engineer so I can provide advanced support to a Firefox dev, just not development as firefox is gargantuan beast of a code base.

Any guidance or pointers would be appreciated, Thanks!
