I-Firefox Community Forum

I am experiencing a severe issue on the LINE Official Account web app (https://chat.line.biz) using Firefox.

Problem Details: 1. Every time I switch between customer chats or type a reply, the chat window automatically jumps/scrolls up to old messages (sometimes minutes prior) instead of staying at the latest message. 2. It happens consistently across almost all chat threads, forcing me to manually scroll down every single time.

Troubleshooting already attempted: - Cleared all Cache, Cookies, Local Storage, and Session Storage. - Tested in Troubleshoot Mode (all extensions disabled). - Toggled layout.css.scroll-anchoring and general.smoothScroll in about:config. - Issue does NOT occur on Chromium-based browsers (Chrome/Edge).

This seems to be a compatibility issue between Firefox's DOM re-rendering/scroll anchoring mechanism and LINE OA's React web app code. Please help investigate.

On my new dell laptop, Firefox seems to run well. however, when I select one of my regular bookmarks from the dropdown, it ignores the choice and chooses a link (e.g. a news story) from the page I'm currently on, one directly under the bookmark I've chosen. If I choose the bookmark link again it operates correctly.

Issue occurred on September 6:When I was running a game and updated my graphics card driver, Firefox was running in the background. My PC went completely black and became unresponsive, so I had to force‑restart the computer.

After rebooting, Firefox reverted to a brand‑new fresh‑install state. All my browser settings, login status, local profiles, browsing sessions, hundreds of open tabs and my categorized tab groups disappeared, only the welcome startup guide showed up.

I logged into my Mozilla account on my Android Firefox device. Some browsing history was synced back. However, synced history cannot restore the original tab session back‑forward page history, nor my manually sorted tab groups. All browser preferences, theme and language settings are also lost.

I originally had 4 separate local Firefox profiles on this Windows computer, isolated from each other for different work purposes. Only one profile was logged‑in to my Mozilla account and could partially sync data. The other three local profiles are completely gone. Those extra local profiles were NOT signed into any Mozilla account and were never synced to cloud storage.

In my Mozilla account’s connected devices list, there are two entries both belonging to this same computer: “MARSHAKK” and “Firefox by Administrator on MARSHAKK”, which correspond to my Firefox instance before and after the crash.

I cannot understand the community help articles about session recovery, and I’m unable to locate or restore my old local Firefox profiles and lost tab sessions by myself. Please give me assistance.

Summary

When using the Spotify Web Player in Firefox, Bluetooth audio devices disconnect whenever the playback position changes (automatic track transition or manual seek). The issue does not occur in Google Chrome or other media applications.

Environment Firefox Version: 153.0.1 (64-bit, Release) Operating System: Windows 11 Home 25H2 (Build 26200) Laptop: Lenovo ThinkPad E14 Gen 5 (AMD Ryzen 5 7530U) Audio Backend: WASAPI Graphics: WebRender Bluetooth Device Tested:

• Google Nest Mini (Bluetooth mode)
• boAt Stone 1010 (same behavior)

Problem Description Spotify Web Player starts playing normally through a Bluetooth audio device.

However, whenever:

• the current song automatically changes to the next track, or
• I manually seek within a song (forward or backward), or
• I manually switch to another track,

the following happens: 1. Spotify continues playing (the progress timer keeps increasing). 2. No audio is heard after the track transition or seek. 3. The Bluetooth device remains connected for approximately 15–18 seconds without receiving audio. 4. After about 15–18 seconds, the Bluetooth device disconnects automatically from Windows.

The Bluetooth disconnection appears to be a consequence of Firefox no longer sending audio after the media transition.

Expected Behavior Audio should continue immediately after:

• automatic track changes,
• manual seeking,
• or switching tracks,

without interrupting the Bluetooth audio stream or disconnecting the Bluetooth device.

Actual Behavior

• Spotify playback timer continues.
• No audio is produced.
• Bluetooth audio stream becomes silent.
• Approximately 15–18 seconds later, the Bluetooth device disconnects.

What I Tested Works correctly

• Spotify Web Player in Google Chrome
• VLC Media Player
• General Windows audio playback

Fails consistently

• Spotify Web Player and youTube web in Firefox 153.0.1

The issue is reproducible with multiple Bluetooth audio devices, indicating it is not specific to a single speaker or headset.

Additional Observations

• Opening other Firefox tabs or using other applications does not disconnect Bluetooth.
• The issue only occurs when Spotify and YouTube changes its audio stream (track transition or seeking).
• Bluetooth remains stable while audio is continuously playing.
• The disconnect only occurs after Firefox stops outputting audio during a track change.

Firefox Information

• Audio Backend: WASAPI
• Graphics Compositing: WebRender
• Hardware acceleration available
• No crashes reported

Steps to Reproduce 1. Connect a Bluetooth speaker or headset to Windows. 2. Open Firefox. 3. Open Spotify Web Player. 4. Start playing music. 5. Wait for the next song to start automatically, or manually seek forward/backward or switch tracks. 6. Observe that audio disappears immediately. 7. After approximately 15–18 seconds, the Bluetooth device disconnects automatically.

Frequency 100% reproducible on my system.

I have used FF on my laptop for many years and AVG AntiTrack on it for 1-1/2 yr without issue. However, today I got a message that appears to be from AVG (but also includes the FF logo) that their AntiTrack is disabled and I need to add it to FireFox, with a "Resolve" button and NO way to close the message. How do I know if it is true or an attempt to hack me? Have there been any other reports of this happening to others? TIA, KBoDolphin

I am unable to make or receive video calls in Facebook and WhatsApp. I used to be able to in Facebook. The message I get is that my browser doesn't support video calls. What is wrong?

Firefox has complained for sometime that my profile was created with a newer version than what I was using. I'd click OK, and go about my day. After about a month, I decided to upgrade so it would stop bugging me. When I did, my old profile did not merge, but was deleted, and now I have lost all of my passwords and bookmarks. How can I restore them when the profile is empty?

Dear Mozilla Firefox Support Team,

I have been a loyal Firefox user for many years because I have always appreciated its speed, privacy, and reliability. However, I have noticed that Firefox has become slower over time, and I am disappointed with its current performance.

The browser feels increasingly sluggish during everyday use. One of the biggest issues I experience is with YouTube, where videos often do not play as smoothly as they should. I also notice that Firefox consumes a significant amount of RAM, even when only a few tabs are open, which affects the overall performance of my computer.

I sincerely hope the Firefox team will prioritize performance optimization in upcoming updates. Many users, including me, want a browser that is fast, lightweight, responsive, and efficient with system resources. Speed and smooth performance are some of the main reasons people choose a browser, and I would love to see Firefox become the quickest browser again.

Please continue improving memory management, reduce unnecessary resource usage, and optimize YouTube and other modern websites for a smoother browsing experience.

Thank you for your hard work and for listening to user feedback. I hope future releases will focus on making Firefox faster, lighter, and more responsive.

Because there were so many attempts at password they stopped my default. I read about having to do something but I am an 85 year old woman and I am sorry but I cannot figure out how to get a ton of passwords done one by one. I sincerely hope that this be taken care of because otherwise I have no way of knowing how to get the Xfinity email to work for me.

Whenever I click any link that will play a video in a video playing website such as YouTube, Instagram or TikTok, it will cause the entire tab to glitch out and freeze in on the page it was on before I clicked the link.. The entire tab completely freezes and never unfreezes itself, with the cursor having whatever appearance it had when the page froze, and being unable to click anything. The only thing it can do is type a new URL into the search bar, but the search button/enter bar is also ineffective, so I'm stuck on a frozen webpage unless I close the tab or change to another one. I've tried troubleshooting, fiddling with the autoplay setting and turning off extensions, none of which worked. Any ideas?

i have been using the old yahoo for years and now it seems they changed the layout to resemble google. it sucks. if i wanted googles layout i would use my google email. if i use this term https://mail.yahoo.com/d/settings/1 i get the old yahoo setup screen and then i have to click return to mail and the old screen stays until i either restart the pc or restart fire fox. i do not see in fire fox setting an area that lets me put in a startup term like chrome has that will restart yahoo in the view i like. being that view is still there.

                                                                                  the new view with the email control tabs to the left and not all show is the right shreen shot or bottom screen shot

Hi. Every time I go into youtube, the sound cuts out after about an hour. I then have to go to settings, volume mixer and Mozilla Firefox and click on the X to get the sound back. Youtube has assured me this is not their problem, but a Mozilla one. I've been with Firefox for many many years and have never had this problem. Could you please advise me as to what to do about this ? Thank you.

Since Firefox does not support video calls, deaf people cannot chat with their friends in sign language on Facebook Messenger. This feature should be brought back.

I am signed in to Mozilla account but the VPN plug in never gives me the option to turn it ON. I see the VPN plug in in the tool bar, every time I click on it, it tells me to sign in to my account even though I am already signed in. It never presents the option to turn "on" like I see in the FAQ. The "Turn on VPN" option never appears.
