Firefox suddenly crashes without any displayed error. Attempt to troubleshoot it in "safe mode" doesn't help (it also suddenly crashes.

• When I had redirected following output: "Exiting due to channel error."
• after restart, I launched "about:crashes", but there were no entries

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 keep receiving a popup seeming to be from McAfee security regarding a virus on my computer. It isn't from that security firm. The ad locks my system till I shut off and restart my computer. This is very annoying and occurs on all installed browsers. Is there anything I can do about this annoying thing?

FIREFOX SETS LILBOBAGS1 PROFILE PAGE AS MY ROBLOX SHORTCUT ON THE NEW TAB, AND ROBLOX RUNS SOOOOO SLOW!

FIREFOX IS [edited] MAKE IT 100000% FASTER OR IM SWITCHING TO CHROME!

I am having difficulty using Google Sheets within Firefox Developer Edition 144.0b4 (64-bit) on Linux Mint 22.2 Cinnamon. When I load any of my Google Sheets, I am unable to scroll. This includes when using a blank sheet.

I also have Firefox 143.0.1, which seems to still be functioning correctly.

Is there any addon or feature within addons management icon (from toolbar) to Disable Extensions and Apps in one-click like Chrome has via this addon?

Why Firefox lacks having right click option (context menu) for multiple search engines like Chrome (Chromium browsers) and Edge has somewhat "Chrome-like omnibar in Mozilla Firefox"?

If I am using a certain search engine as default but don't use it all the time or want to use another without changing the default search engine or want to search a term or sentence via any search engine, then Firefox has no such option or addons (yes, checked thoroughly for latter).

Opera has from day one, Vivaldi also has it, Chrome allows it via extensions, Edge does via addons, Brave as chrome does via addons, Naver Whale (South Korean browser, underrated, seriously) has options to put more than 1 search engine for search results.

Adding images below for reference.

Why Firefox is seriously so old and outdated and nowhere close to standards of 2024 and 2025?

Somebody made a post 10 years ago around 2014 🤯🤯🤯 and Firefox, as usual went their way as they are doing now.

I don't need to pin tabs, ever. Every time I try and drag a tab to the first slot, it always pins the tab, and I don't want it to do that. Is there a way to disable this stupid feature?

When signing in to websites, firefox offers e-mail address options that havebeen used before on that site. But right now it keeps offering two, one of which is incorrect, and I thought there was a way to fix that, but right now I cannot remember it.

This is explicitly for sites where I have told firefox *not* to save the password, and it is offering up potential email/login. entries *only*.

I do not want to tell firefox to not offer to autofill anything ever, because that saves time when the entries are correct. but here they are *not* correct and I need to clear them for this one specific website.

How do I do that?

I GOT TIRED OF FREQUENT FIREFOX CRASHES (C0000005) IN BOTH THE 64-BIT AND 32-BIT DESKTOP VERSIONS. I HAVE BEEN USING THE 64-BIT VERSION IN WINDOWS 11 (I HAVE A HIGH-END SAGER LAPTOP WITH 32GB RAM. I INSTALLED THE FREQUENT FIREFOX UPDATES BUT THE PROBLEN PERSISTED EVER SINCE VERSIONS 42X WERE RELEASED. I TRIED THE 32-BIT VERSION BUT THE PROBLEM PERSISTED. FINALLED, I TRIED THE DEVELOPER VERSION: NO MORE CRASHES! I READ THE RESPONSES FROM YOUR CLUELESS STAFF TO OTHER CUSTOMERS WITH THE SAME TROUBLE. THIS IS NOT A WINDOWS ERROR; THIS IS A FIREFOX APPLICATION ERROR. MAYBE SOME OF YOUR FIREFOX DEVELOPER CODERS SHOULD ASSIST THE 32-BIT AND 64-BIT DEVELOPERS. OR, DUMP THE VERSION 4X CODE AND BUILD ON THE MORE STABLE 39X CODE. ALSO, DON'T BLAME WINDOWS FOR FIREFOX APPLICATION ERRORS. AND...NEVER SUGGEST A WINDOWS REINSTALL FOR FIREFOX ERRORS!!!

Web pages that are supposed to contain emojis are blank. I can highlight where emojis are supposed to be shown but the actual images of the emojis aren't there. about:config font.name-list.emoji correctly contains "Apple Color Emoji" If it is relevant, this has been a bug/issue that has persisted for a couple of months now (can't name an exact date).

Hello. Why nexusmods.com and loverslab.com are blocked (Secure Connection Failed) on my FireFox Dev Edition 150.0b6 (auto updates)? It bothers me to use it as a default browser. Both nexusmods.com and loverslab.com are ping well and work fine on any other browsers.
