So this problem is isolated with Firefox as it doesn't happen with Edge or VLC on this pc. If I have Twitch or Youtube, probably any other audio or video playing, open when I turn the monitor off the audio will no longer go through properly when it is turned back on. The video is still playing fine but the audio isn't going through properly. Refreshing the page fixes the issue.

I have made sure to disable all other audio outputs and defaulted the current HDMI output. Audio playback works fine on every other application that I have tried.

Running Windows 11.

Hello, I know when I closed the firefox browser , I can reopen firefox browser and click "settings"-- " history" --" Restore previous session" to retrieve all the webpages I was viewing last time. but this time it seems I made a mistake . I closed the firefox browser in the beginning with many valuable webpage still opened, after I restart the firefox browser, I close the browser by accident without firstly reloading all the restore previous session . Then I have to open firefox brower again, and try to click "settings"-- " history" --" Restore previous session" to try to retrieve all the webpages I was viewing in the first time. but this time no previous session can be loaded. since those webpages I was viewing are important webpage I need to check, May someone tell me how to get those valuable webpage link again? I know I can try to find those webpage link slowly by checking all the history day by day. but honestly speaking, I have 15 around webpages in the firefox brower and some of them are viewed around 20 days or 30 days before . I haven't closed my firefox browser for almost 40 days so it will be very hard for me to search the history webpage to find out them one by one. I am not sure whether there are some tips to try to load the "restore previous session " again for the first firefox browser I closed.

I have it set in setting to open in Firefox. it is continuing to automatically download all PDFs and it is eating into my data! please help. I have to get this to stop or I will no longer be able to click on any PDFs with Firefox anymore. I have also tried setting it to always ask, but if I do that and then tell it to open, then it STILL DOWNLOADS THE FILE! I cannot understand why anyone would ever want files they just wanted to read to just randomly download. I am a genealogy researcher and used to click on dozens of PDFs a day to read, now I can't with Firefox or I won't have internet for half the month after I use up my data. There has to be someway to stop this, I don't like other browsers, but right now, if it involves a PDF I have to use a different browser. (also quite annoying to have to delete multiple files that I never wanted to download - I was using Firefox to pay a bill and downloaded it SIX times) Please help!

Hi, I'm a very happy long time Firefox user. I use the extension "Dark Background and Light Text" so that my webpages are much more easy on my eyes. The extension works everywhere but in "support.mozilla.org".

How is it possible to have dark theme in Mozilla's support pages too?

Thank you very much. Prayan

when reopening closed tabs it doesn't open last closed tabs, it only opens closed tabs in the window you are using. so if you have closed a window it doesn't reopen like it does on chrome

How can I uninstall the latest Firefox Update? My version is 105.01. When I right click on the file menu, there is a blank menu, except for the "Bookmarks Menu" is the only thing. Also, the side menu on the right side is useless. None of the commands show except for a couple keyboard shortcuts. I tried changing themes and also changed to the default theme with no luck.

I rely heavily on the menus so i would love to roll back/uninstall the update. Thank you. nottyn

Today the autofill feature for passwords / username stopped working on Protonmail login. Windows 10. Specifically the username option. I have two accounts and formerly could select which account. Now i have to enter the username manually, however the password tab still works for password autofill / selection. This is the only site I am having this issue with.

I'm signed in on desktop and phone (they are synced), but I forgot my password, and I don't have a recovery key. I want to reset the password to avoid losing data, just to prevent. If I back up my desktop profile, then reset my password, will this backup be enough to recover all my data? Or is there something that it's stored just online/on cloud by firefox that won't be recovered?

Accidentally added a misspelling to the Firefox dictionary. Thought it would be easy to locate and edit the dictionary.

Enabled 'show hidden files.'

On XYplorer, and Windows File Explorer can find not a single trace of 'persdict.dat' in my profiles folder.

It would be really helpful if you could advise what the next step would be. Thanks.

I reset my windows and downloaded firefox but all my data synced to my previous firefox on this same account has been lost. Please help me recover that synced data including bookmarks, logins, passwords, etc.

After updating Firefox this morning on my main PC, I noticed that it didn't ask for my primary password.

I then noticed that it wasn't filling in passwords automatically.

My primary password has disappeared as well as my stored passwords. When I try to set a primary password it tells me that it can't change the password.

I tried creating a new profile and that didn't fix it.

I can use firefox on other devices and all the information is there. But I can't get my passwords on my primary PC.

How do I fix this?

i'm running Firefox 105.0.1 (64-bit) on a Win 11 PC.
