Has anybody else experienced a similar problem? Or can you help me trouble shoot this issue please?

I'm busy playing audio in a tab of the browser. The sound quality is good (rich, full, deep). Next, I open a new window by any means (Ctrl+N / Open link in new window / Menu > New window) As the new window appears, the current audio playback becomes tinny / lower quality. After a 3 seconds, the normal good sound quality starts again.

I'm currently using Bluetooth connected headphones and this happens on different headphones. I have to find some wired headphones first before I can try that. This happens with every new window that I open, regardless of the number of open tabs in current windows or how many previous open windows I already have. This happens regadless if audio enhancements of the output device are enabled or not. Spatial sound is set to off. Windows is set to 'do nothing' & will not adjust the volumes of different sounds when I'm using my PC to place or receive telephone calls.

OS: Windows 11 with latest patches Firefox: latest & older builds Hardware drivers: All manufacturer drivers applied

PS I can replicate this issue by changing between the 'Playback' & 'Recording' tab in the Sound Control Panel applet. That is to say, the same decrease in audio quality happens when I change from the Playback tab to the Recording tab. Audio quality improves again when I change from the Recording tab to the Playback tab https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2026-09-12-15-38-23-1accad.png

PPS My new windows are set to open on 'about:support'

Help! My bookmarks tool bar is missing & I cant recover it because your instructions for locating the menu bar don't match what your instructions display. There is NO AltGr displays a bookmark menu BUT I CANT MOVE IT TO MY TOOL BAR. There is NO selected tab, NO menu bar; NO bookmark tool displayed. I have also lost all of my downloads. This has happened in the last month; everything was fine. I am 82 years old & NOT a techie so expect better help than I have received so far during the last frustrating 2 hours of trying to follow Firefox instructions that DO NOT APPLY TO ME. Also the "add images" function @ bottom of this page won't let me send you a copy of the instructions you display to select the bookmark menu bar ... I click on the picture of the problem & nothing happens ... just dead no access to select pictures either.

I have NOT changed my internet provider; I have not changed any settings. This all happened two weeks ago. Called internet provider & they said it was Firefox issue!!! Very unhappy.

I usually have checked the option for clearing cookies and site data every time I close Firefox. However there is an exception list where I add sites I visit often and I prefer to keep its browsing data. This list of exceptions seems to be ignored. The sites I have in the list lose all their browsing data.

The only solution I have found so far is not check the option to clear browsing data.

I remember this function stopped working correctly right after I decided to wipe all browsing data manually.

I use Firefox under Fedora (I'm two OS versions behind, must upgrade soon). I open very many tabs each day then work through them, theoretically every day, in practice they accumulate and I deal with them when I can. I rely on the tabs loading correctly on restart, but today they didn't, instead the set of tabs that were opened a few days ago loaded, and I lost everything I had done since then. Is there a way to retrieve the tabs that were opened just before this happened, ie around 15-20 hours ago? Ideally, again, I would merge them with the current ones, but reopening the old ones would take much much longer than reopening the new ones. Thank you for any advice.

I do not wish any of my passwords to be stored anywhere it isn't absolutely necessary. My own highly secure method I've been using for many years is listing them all on a removable drive that is encrypted and only in my PC's when necessary. Therefore, I wish to disable any and all PW Managers in the software I use. Please instruct me how to permanently disable the PW Manager in all Mozilla software.

Everything is stated above with an explanation of the reason.

Thanks for your help. TJS

latest update seems to have broken firefox 155.0.1. It opens but then becomes unresponsive. Two different PC, both win 10. How can I revert to previous?

I can not get extra info from troubleshooting page cause FF won't open so as to be used.

I used to be able to use UK in the free VPN list, over the last 3 days, since I updated my firefox, I am unable to do so. Has anyone else down under had this problem, if so is there a solution to the issue.

Thanks in advance

I am on version 155 of the browser, and the sidebar is not showing up for me. Clicking the sidebar toggle button also does nothing. I've tried going into settings and toggling the show sidebar option, but that also doesn't do anything, as if the sidebar feature doesn't exist. Toggling vertical tabs just makes the tab bar disappear, and I've tried both the options menu and right-clicking the side bar toggle button. Is there an error, or am I missing something?

Hi ì just want to ask how does it happen that when I use the Firefox bar search engine and when I type something to search i find myself typing in google search bar even when i haven chosen Firefox as a or on defaulter.

And also Please check for me what is making my data to finish so quickly, it was not like that at first but now my data doesn't last for long anymore.

Thank you M
