Firefox Support Forum

Hello

When i try to watch a twitch stream i can't do that, it shows me this error Your browser encountered an error while decoding the video. (Error #3000). I'm in firefox, Version 105.0.1(64 bit) I tried delete data and cookies,restarting firefox and pc,starting firefox in troubleshootmode

I'm trying to present my screen on Google Meet, but it appears to be blurred to other people in the meet. Other's say that sometimes it clears but only for a quick second. I was forced to install Google Chrome and I don't have any problem on my presentation. Everything was clear. I already tried to disable all my extensions, still the problem persist.

This is the message when the sync between devices failed. Wrong state for fxaccounts:pair_supplicant_metadata. Valid expected states: PendingConfirmations, PendingLocalConfirmation. Current state: Errored.

Hi,

I have set Firefox to delete every cookie when I exit. However some websites use cookies for dark mode. My question is this : can I make it so Firefox continues to delete every cookie but save only some specific cookies For exemple, linkedin uses a dozen of cookies and two of them are used to store value for dark mode. Can i save only those two ?

Thanks in advance

On this page with an Atari emulator, I am unable to use its controls that use the Alt key, such as Alt+P to pause.

It works with another browser, or with a fresh profile.

I've tried disabling add-ons and trying it again, but it fails even after disabling each of them. It also doesn't even work in troubleshooting mode, and that seems kinda odd?

It may be some modified settings in my Firefox profile? Though if it is, I don't know what settings, nor how to fix it. What sorts of settings are retained even in troubleshooting mode?

Sometimes, when I have 4-5 tabs open, I scroll on a page and suddenly everything freezes. The opened pages are news portals I can't switch between pages, I can't close pages Switching to another application in Linux everything works fine. I can close Firefox and restore the previous pages after reopening. No error message. The about:crashes is empty. In gnome-system-monitor firefox-bin looks good

Linux Mint 20.3 Cinnamon Everything is the latest version It is not caused by a Firefox add-on

Sorry for my bad English

I've just rebooted and I've lost two windows with thirty tabs, or something.

When I started Firefox, there's nothing in the Recently Closed [Tabs, Windows]

Reading online, I see that Firefox should be writing some files to the sessionstore-backup directory, like these:

recovery.jsonlz4: the windows and tabs in your currently live Firefox session (or, if Firefox crashed at the last shutdown and is still closed, your last session) recovery.baklz4: a backup copy of recovery.jsonlz4 previous.jsonlz4: the windows and tabs in your last Firefox session upgrade.jsonlz4-build_id: the windows and tabs in the Firefox session that was live at the time of your last update

, but I only find recovery.jsonlz4 and recovery.baklz4 and both are tracking current time, which means they are getting data from the currently opened Firefox.

These are the only files I find in this directory.

Where are the other files supposed to have gone?

Hello :)

Firefox 102.0.1 crashes after some Time. Firefox then is unable to switch between Tabs and stuck at the opened Website.

For testing Purpose i start over with a new profile and did not install any Add-ons. The behavior was the same, it crashes after some hours.

My System is Ubuntu Mate (Ubuntu with Mate Desktop) in Version 20.04.

Here has someone the same problem: -> https://bbs.archlinux.org/viewtopic.php?id=277649

Thanks for any suggestions.

Hi everybody this will be a long question, and I would be really grateful for any kind of help anyone could give me, this is my case:

I use `firefox-sync` to manage all my logins information and firefox-sync's password is the unique password I save manually.

Currently I has problems with my O.S and I decided reinstall it. But also I have 2FA enable for mostly of my accounts, and firefox-sync is not the exception, and firefox-sync's 2FA is based on my gmail, so when I tried get logged on firefox-sync, firefox asks me for my verification code, but my verification code is in my gmail, and my gmail's password is in firefox-sync.

So I lost access to all my accounts, I lose my gmail, github, gitlab, stackoverflow, discord, etc etc... :'(

From the gmail side, I tried all that gmail let me try but unsuccessfully.

So, the only possibility that I see, is recover the information of the formatted partition and rebuild the previous state of Firefox. I mean:

Reading about firefox loggins, and taking a look to firefox's workdir (`$HOME/.mozilla`), I see firefox saves login's info in a json file located in `$HOME/.mozilla/$profile$/logins.json`.

So the basic idea is with a data recovery tool, try recover `.mozilla`s directory and replace it over the current environment so when I start firefox can get access to my login's info. But I'm not sure how much it is possible to recover the whole directory, and if is not posible, my question is:

What files next to `logins.json` should be my recovery targets to replace inside the `.mozilla` folder in order to reconstruct my accounts login information?

Recently, after my computer get repaired, I had to do various things, such as reinstall some software and, in the case of Firefox, put back my bookmarks and rss feeds (they were lost and if there was a backup, I didn't find it)

The problem only happen with this page. I didn't find any other page with this problem.

I checked all what I can about this page (using view-source). I compared it with other xml files, mostly other rss, and the documentation I found about rss, xml and html. Visibly, this is a regular xml/rss page. I didn't found anything special in.

There are element underlined in red in the source code but it is mostly what can be seen as an error if this is parsed at assuming it's html code.

I also check what I get if I do a right click then, in the contextual menu, I select "inspecter" (sorry, on my computer, Firefox is set to french and I don't know the english term ; this is the last entry of the menu). I got a different code. Apparently, Firefox applied (pseudo) fixes to display the page as an html document.

I checked the name of the page. This is unusual but, in my rss feeds, there are several other rss feeds named this kind of way and all of them work properly.

The last thing I checked is the RSS link that is on most pages of the site and send to this glitched page. It doesn't seem to be more the cause.

Visibly, for an unknown reason, Firefox decreed this is html code and I found no way to make it reconsider this or parse this page as xml.

It seem the first mention of problem with the rss feed on this site was a comment written almost four months ago but I don't know if it was the same problem.

I have Firefox installed on Linux (Fedora), Windows, and macOS, and on Windows and Mac, I can use ctrl (cmd on Mac) + shift + Y to open the Bitwarden extension. On Linux, this instead opens the downloads library (which is normally ctrl + shift + j...). Is there any way to change the shortcuts on Linux to be the same as the other two OSes? Judging by the many many open questions on this site about changing shortcuts, I'm not holding my breath...

If i open the Passwordmanager firefox askes my masterpassword. After entering it correctly the list shown is empty. exporting to file doesn't export. It shows where to export and the filename but nothing is saved.

Logins still work using autofill so the data is still stored somewhere.

Can you fix FF hanging on 1 core, sending to 100% and freezing Firefox. I mean people have only been complaining about it for over a DECADE !!!!!!!!! People are dropping FF in droves. Stop with the releases and just fix it already.... It used to be the best now its like 6th and falling.......
