Diễn đàn hỗ trợ Firefox

Hello, I am currently using Firefox Beta and I would like to switch to the regular Firefox Release without losing any of my data (browsing history, bookmarks, passwords, add-ons, and settings). I would appreciate guidance on the safest recommended method. Specifically:

Is it safe to install the Release version over Firefox Beta, or could this cause data loss or profile conflicts?

What is the best way to create a full backup of my Firefox profile beforehand?

Should I expect any issues with add-ons after moving from Beta to Release?

Do you recommend enabling Firefox Sync as an additional safeguard, or is a profile backup enough?

In case something goes wrong, what are the recommended recovery steps?

My setup:

Operating System: [windows 10 ]

Thank you for your assistance.

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.

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 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!!!

Hello why my firefox installation 1440b6 64 bit on windows 10 do not autocomplete the third field in a form login ..

namely , username and identification password are correctly filled , but the third field (that in my case are named "company ID") would not, it remain empty, and i need to manually fill in each time. Actually this happen only on a one site , but may be because only this site that i use have a three field to fill in the login page...all the others need only password and username

thankyou kind regards klx140

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?

I really enjoy the new sidebar revamp, but I've had an issue with it recently that I haven't been able to find a solution for. Typically, the settings gear is supposed to be situated near the bottom of bar. However, as demonstrated in the attached image, it is at the top near the bookmarks and history buttons. I have tried reinstalling the browser from scratch, turning the sidebar on and off, turning vertical tabs on and off, and even getting rid of my custom CSS theme for a time. None of these have worked. If anyone knows what the root of this issue is, I'd really appreciate the help.

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?

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.

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

Hmm. We’re having trouble finding that site.

We can’t connect to the server at marvelsearch.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox Developer Edition has permission to access the web (you might be connected but behind a firewall)

i am using a local dnsserver and firefox is connected to it. is this the reason? if so how can i disable this? other firefox features are working beautifully.

Since version 148.0b2 (64-bit), it's once again not possible to enter search terms in the search box of a new tab; instead, the browser searches in the address bar. I've had all the settings I found in the forums configured correctly for over five years, and they haven't changed. - browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar = False. Despite this, the search still occurs in the address bar. Now I'm back to the awful search in the address bar. How can I fix this? Please fix this bug as soon as possible.

Original: Set der Version 148.0b2 (64-Bit) ist es wieder nicht möglich die Suche im neuen Tap, im Suchfenster einzugeben, sonder es wird wieder im Adressfeld gesucht. Ich habe alle Einstellungen, die ich in den Foren gefunden habe schon über 5 Jahre so eingestelle, sie sind auch nicht geändert. - browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar = False. Trotzdem wird die Suche im Adressfeld geführt.

Jetzt geht es aber wieder mit der Schrecklichen suchen in der Adresszeile los. Wie kann ich dies ändern? Bitte diesen Fehler (Bug) schnellst möglich beheben.

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?
