Firefox used to start in a second on my Windows 10 PC. But lately it now takes about 10-20 secunds to start (on 143 beta). Is there any reason why it takes so much longer to start now? Is there any setting og tweak I can do to get it to start faster?

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 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?

Developer edition seems to be blocking Today's Deals when browsing amazon.com. Regular firefox does not do this. Suggestion on what to do to fix it.

Also trying to browse distrowatch give the following: Warning: Potential Security Risk Ahead.

This is the 4th time I've reported this problem. Here's the warning I get every day only after I have already been loading Newsmax pages with no problems:

Secure Connection Failed

The connection to www.newsmax.com was interrupted while the page was loading.

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

There are no other sites in which I have this problem with FF x64 DE. In Edge, I see the newsmax pages load while the FF x64 DE https//newsmax.com xontinues to genberate the above message and fails to load the screen.

Please fix.

Thanks, WaltC

Whether a person clicks the fullscreen indicator or types F on the keyboard, the cursor will remain on screen as the video is playing until it is again moved. This also affects video played through the browser on steampowered.com. This issue appeared as of 143 and is still going strong in 144. This seems to be macOS specific as I am not noticing this behaviour on the Windows client. Could be a conflict with Tahoe.. I don't really know at this point.

There used to be a website where you could fire off a 'Firefox made me happy/sad' which is where I would've preferred to send this. So, have other people encountered this issue? And if so, are there any lasting solutions beyond wiggling the mouse?

1] Topic list is insufficient; 2] I tried to use the share data option of <;tblshg ; > troubleshooting. It could not automatically collect data, so I returned [back icon] to the form and found the form blank. The write-up I had spent well over an hour preparing was simply GONE.

No reply needed, buy that needs a fix. how could that ever pass QA.

I cannot find "Sync and save data" button in my mobile browser, making it impossible to sync the devices. The instructions provided by the settings lead me into the dead end.

After the 8/5/25 Firefox update the internet is inaccessible on my laptop through the standard Firefox browser. The internet is accessible with MS Edge. Toolbar is set to always show bookmarks but none appear. Also, the browser's application's menu does not open to access options such as restore previous session, recently closed tabs, etc. I've restarted my device several times without it resolving the issues with the standard browser.

The Firefox developer version opened in command prompt safe mode (firefox -safe-mode), which is how this inquiry is being sent, but no bookmarks on tool bar or current page history from the standard (non-developer) Firefox.

I'd like to return to accessing the internet using the standard Firefox version with its bookmarks, history, etc. I am using Windows 10. Thank you.
