I'm on OSX Catalina 10.15.7 and all of a sudden I am unable to get any sound from my FireFox browser. I tried to play audio/video from 3 different websites - Youtube, 123greeting.com and Gettr and while the video played, there was no audio coming out on any of the sites. I have no problems watching and hearing videos on my other browsers - Brave and Vivildi so this issue is with Firefox on multiple websites. Please advise as to where to look for some switch to turn the sound back on my Firefox browser. Thanks

Hello,

I am trying to login to my Mozilla account so that I can backup my data and move it onto a new computer. However, even though Sync is activated, I cannot find my Mozilla Firefox password anywhere and am unsure of what it is. Is there anyway that someone who works at Mozilla can give me access to my password?

I am happy to verify my identity and prove that this is indeed my account, but I am not sure of how to go about doing so. I really need access to all of my data, and would be highly thankful for any assistance regarding this matter.

As per subject. When i click a Mailto link in a webpage, eMClient opens OK, but message window does not. Seems to be a Firefox problem because it works fine in Chrome. I've checked the Firefox and Windows (10) settings; all seems as it should be. Any suggestions? Thanks.

I often use Ctrl+Number to jump to a fixed tab, whereas on Linux the shortcut is Alt+Number, which causes some inconveniences. Is it possible to make Firefox use Ctrl+Number to switch tabs on Linux?

The first time i enter fullscreen for the on the current monitor, the window is not filled completely. It fixes itself if i exit fullscreen and enter it again.

I did not observe this behaviour in 124.0

this also happened like 1 year ago. i made a comment about this in a bugzilla thread right here: https://bugzilla.mozilla.org/show_bug.cgi?id=1763981#c119

The fix mentioned in that thread is applied for me.

It does not fix it.

My internet has 750mb of bandwidth. Updated 64bit Firefox can only provide 320mb. I installed Chrome and the internet went to 800mb. What could be slowing down internet speed in Firefox? I restored Firefox, restarting everything. I did the same with Windows 10. I restored it to an earlier date. It didn't improve anything. What to do ?

When I start FireFox most times the browser comes up then stops and restarts with a pink color on the web address line. I have tried making changes in settings but I can not find a setting for this. If I restart Firefox right after this happens, I cn search or browse without the Pink address line. Why is this happening. It would be nice if FireFox technicians would respond to help questions instead of sending questions to a forem...

It was working fine and now the past few days I can no longer login to my Fastmail.com account other than from my Windows 7 pc

So no one including Firefox can email me

I am trying to email a link from chatgpt to my yahoo email account. When I try to open the link I receive the error 500 internal server message. I have emailed links from chatgpt many times before with no problem. Can you advise.

Thank you Barbara Krausher

Why do I need a new profile every single little update? How can I get my saved session, bookmarks, history, open tabs, extensions and preferences from my old profile? Manually copying files from the old profile is not a solution - it's a workaround and not a great one. Lots of things get left behind. Alternatively: what file in my "old" profile do I need to manipulate to trick Firefox into using it with the new version?

Hello, I have a very weak internet connection and I've been experimenting with ways to lessen the burden of the slow connection by increasing the time that the cache from websites can stay on my computer (I've already increased browser.cache.disk.capacity and set browser.cache.check_doc_frequency to 2, but the files still end up expiring eventually forcing them to be re-downloaded even though I know these cache files never change).

So far I've had some success with this extension (https://addons.mozilla.org/en-US/firefox/addon/cache-longer/) it definitely works but very inconsistently so I've tried to directly edit the cache files found in Profiles\someprofile.default-release\cache2\entries but every time I edit the max-age on the cache-control line or any other line firefox just erases the cache file completely then re-downloads it.

TL;DR - Is there someway of getting firefox to ignore the cache file expiry dates and cache-control age or at least editing these files to extend their life?

I appreciate any help in this!

Hello, maybe someone else seen the same issue.

Why Firefox could respond with VP8 to the H264 request?

I use passkey verification for a website. In other browsers, I can get a QR code to scan with my phone to login. In Firefox, I only get a popup saying Touch your security key to continue with <site> (image attached). In Chromium, I have options for both (image attached). Is this possible in Firefox?

I used CCleaner this morning to scan and clean up my computer. (I did it over the weekend as well and it didn't affect my Firefox). Now I can't even open Firefox. the icon on my windows taskbar is gone as well. I tried to uninstall and then reinstall Firefox, but that didn't work. I also tried to "refresh" Firefox (or whatever it is called that is recommended when trying to uninstall).

Please help. I really need my Firefox to work!

Thank you, Jeri

For some reason the developer tool on Firefox is just completely blank when I open it. Nothing will load and I can't even close out of it. Any ideas on how to fix this?

We are receiving the following error when we change the security.OCSP.enabled to "1" and security.OCSP.require to "true":

(Invalid OCSP signing certificate in OCSP response(Error code: sec_error_ocsp_invalid_signing_cert)

We are in an airgapped environment and have our own OCSP responder we are attempting to get Firefox to work with. What configuration does Firefox need in order to solve this error?

I often run into issues with PDFs in Firefox Linux. They either appear totally blank (typically after suspend/restore), or they appear with the desktop background showing through (as in the attached screenshot).

Hard refreshing the page doesn't change anything, opening a new tab and opening the PDF again doesn't change anything, opening a new window and loading the PDF doesn't change anything.

The screenshot is with this PDF: https://www.sgsw.ch/home/strom/_jcr_content/Par/sgsw_accordion_list_1838160259/AccordionListPar/sgsw_accordion_12353/AccordionPar/sgsw_downloadlist/DownloadListPar/sgsw_download_1049323524.ocFile/2023-08-31%20Mitteilung%20Elcom%20Erh%C3%B6hung%20Elektrizit%C3%A4tspreise%20f%C3%BCr%20das%20Jahr%202024.pdf

It renders correctly in Chromium.
