Hello Firefox Support Team,

I would like to report a browser compatibility issue regarding CSS positioning behavior that differs from Chromium-based browsers.

• • Issue Description:**

When an element with `position: sticky` is placed inside a container with `position: fixed`, Firefox treats the sticky element as if it has `position: relative`, effectively breaking the sticky positioning functionality.

• • Expected Behavior:**

The sticky element should maintain its sticky positioning behavior even when nested inside a fixed-positioned container, as it does in Chromium-based browsers.

• • Current Firefox Behavior:**

The sticky element loses its sticky properties and behaves like a relatively positioned element.

• • Use Case:**

This issue particularly affects modal implementations where: - The `body` element receives `position: fixed` to prevent background scrolling - Page elements (such as `.total-section`) should maintain their sticky behavior regardless of changes to the body positioning

• • Browser Comparison:**

- **Chromium browsers (Chrome):** Sticky positioning works correctly in this scenario - **Firefox:** Sticky positioning fails and falls back to relative behavior

• • Request:**

Could you please consider aligning Firefox's behavior with other major browsers? The current inconsistency creates cross-browser compatibility issues and forces developers to implement JavaScript workarounds.

Thanks!

I can NO longer log into my BANK, I changed the security settings back to "standard" but I STILL CANNOT LOG INTO MY BANK. it's website acts as though I'm a new customer & want's me to open an account,I ALREADY HAVE AN ACCOUNT & HAVE HAD AN ACCOUNT AT THAT BANK FOR MANY YEARS! I have jumped through many "loops" at the bank trying to fix this mess, but they can't,FIREFOX IS NOW THE PROBLEM & someone needs to find out what they changed in their updates that has prevented me from logging into my BANK.

A week ago I got a BSOD that ruined settings of most of my extensions and most likely some of Firefox's settings too (at least it erased my custom findbar.matchdiacritics value, but probably not just that). After that I moved Firefox's folder and re-installed it. I also created a new profile. The 2 profiles are synced. Because of that, the new profile got (almost) all the extensions from the old one automatically. Then, I decided to do a clean install of those extensions (the reason why is a story for another ticket). So, while both profiles were opened, I removed one extension in the new profile, waited for a bit and checked the old one to see if it got removed from there too. At first it wasn't, so I thought they are not synced (anymore). Yeah, sure, but once I removed all extensions from the new one, the old one woke up and removed all extensions from there too. Great! Awesome! Loved it wholeheartedly! It really had to wait until I removed them all, didn't it? Anyway, I had a backup of my old profile, so I restored my extensions and their settings on both profiles eventually. So now I have clean installs of Firefox and extensions. Back to the issue. I can't load Steam pages (at least store.steampowered and steamcommunity) normally anymore. They load forever, and if the blue dot eventually stops moving (after an insane amount of time), it's either a plain white screen, or badly loaded page with most images missing.

• Edge loads them just fine
• Steam client loads them just fine.
• If I turn on VPN plugin (I use Browsec), then it works. It's like that in both old and new profile. That's why I mentioned that funny little story before.
• Tried Troubleshoot Mode, didn't help.
• Tried to selectively disable some extensions, same.
• Obviously tried to remove cookies, Ctrl + F5 and whatnot. Btw, if I clean everything and try to load it, then it's (most likely?) a white page, but if I turn the VPN on and load it first, and then turn it off and reload it, then it will look a bit better, but still will load forever with some media missing. (Which kinda make sense since something was already cached.)
• Tried to change proxy settings from “Use system proxy settings” to “No proxy” and “Auto-detect proxy settings for this network”, nah-ah.
• Tried to disable DNS in Firefox's settings, no siree.
• The console throws different warning and errors every time (that are probably even unrelated). Or none at all.
• Probably tried something I already forgot about.

Also, it seems the culprit is actually Akamai (it's where the Steam stores its media) or whatever is preventing reaching it. Because it often shows something like “Waiting for community.akamai.steamstatic.com...” in the status bar for a long time. It seems like the problem is within Firefox's settings, and it also looks like settings aren't synced across profiles (or at least some aren't, I definitely had to configure them on the new profile manually). Anyway, I am out of ideas and my butthurt thrust is about to deliver me to Uranus. Thanks for your attention!

I am using Firefox desktop on Windows 11. I have downloaded hundreds of articles from this website, with no problem until yesterday. I accessed the website using Edge, and it worked fine.

When trying to access a particular article to download it to Ancestry, the following message appears:

Application error: a client-side exception has occurred (see the browser console for more information).

I accessed the browser console for more information, which I'm sure someone can understand, but not this grandma. This is what I got:

I really don't want to stop using Firefox, but I need a usable browser. Can you help me?

When I try to go to costco.ca I get a connectivity error saying site cannot redirect properly. This site works with IE or other browsers.

The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

When I'm on the Guide page, the option to change the guide to later in the day is not visible until i reduce the page to 90%.

However, when you try to advance the time, it does not work. Is shifts momentarily to the next time period, but immediately reverts back.

It works properly in Chrome.

Good morning,

Firefox is not loading webpages correctly this morning. From Gmail not displaying or opening individual emails, Amazon not opening, to Youtube and several other sites not loading or displaying correctly. I had no issues at 9 PM PDT yesterday.

No changes to the computer, and everything is up to date.

I have successfully opened the above mentioned sites and others on MS Edge this morning.

Thanks!

For over a week, Firefox always displays the message "Our servers are experiencing problems with our services" when I try to view a TV program on YouTube TV. Opera, Edge and my iPhone do not have this problem. I notice that Firefox doesn't store my location in the same place other browsers do. Could that be the problem?

I hate it when I have to use a different browser.

I'm using the latest Firefox. All of a sudden as of this morning, Firefox cannot not load Facebook or Twitter. I can open YouTube and YouTube videos appear but will not play (just a spinning wheel when I try to play). The Amazon landing page is scrambled with code. (see image attached)

I use Ghostery ad blocker but the issue persists when Ghostery is paused. I can use Safari without issue. Can anyone offer any insights?

When I read a thread and then it shows comments I can't read them on Mozilla anymore

I went to Google Chrome and I can read them so its something with my browser

we have built and using Asp .net application and its handling student and employee data while saving any fee receipt in recent version of fire fox 141 its giving we apologize error but in version 133.0.3 its working fine , its seems the Infragistics girds we are using in web page is giving issue , kindly suggest to avoid this problem.

Twitter/X does not display, only an error message that says Twitter/X does not work with Firefox' advanced tracking (or similar). Requesting someone at Firefox and someone at Twitter/X get together and fix this so these two entities play nice with each other. Thank you in advance.

Will Firefox ever be updated to use end to end encryption so that users of Facebook Messenger can do audio and video chats as they did before META's change?

If not, Mozilla could lose a lot of Firefox users of Facebook Messenger. That includes me. I have been with FF since v0.93 :-P

Messenger audio and video chats work fine on several other browsers including Brave. There is even a Messenger App on the Microsoft store.

I would really like to see someone at Mozilla answer this.

I received a new computer, I installed Firefox on it and tried to install gmail in the Firefox. There was a bunch of things it wanted me to do and when I had completed them all I get is a screen that says it is Gmail and has a primary tab a social tab and a promotional tab on it bu no mail. what I have I not done. I would like the gmail the same way I have it in edge and google.

I have been using ChatGPT for a few months with no problems on Firefox but today I am not able to enter any text in the text field where you communicate with Chat. However, I can turn on the microphone and then after speaking a command I can hit enter and it works. I can also switch to Chrome and it all works fine. I tried clearing my data and cash, rebooting computer but still isn't working. what's going on?

Gmail works on my phone (Android), Chrome, Opera, etc. It will no work in Firefox that I have used religiously for over 10 years. I've signed out of gmail and signed in...a dozen times. Nothing works. If I wish to read my emails, I switch to Opera

Why?

When I try to sign in to Yahoo I am sent to a Google sign in. I tried that and only got gmail and not my yahoo mail. I can sign in fine when I use Firefox private browsing and Edge. Why is Google involved with Yahoo mail?
