I've been having trouble with seeking through video on firefox and can't seem to find a way to fix it.

Theres always a lag/buffer right after I skip through a video but this doesnt happen on other browsers like edge/chrome. I don't know how well you can tell in the video but it happens on other websites not just youtube.

I have tried disabling all my extensions and some other stuff with webm in about:config but nothing seems to work.

Also confused as to why media.benchmark.vp9 fps is 0 and version is 0

I'm on a 2023 xps 15 with i7-13700H and 4050 with 32gb ram.

Would appreciate if anyone has any advice since i've been searching everywhere for a solution and nothing has worked. The video trying to show the issue on a reddit post i made to try and get help: https://www.reddit.com/r/firefox/comments/1914bcc/help_with_video/

After updating to 121.0.1 some sites, primarily Flickr, are terribly slow in comparison with other browsers (Chrome, Edge). The issues are related to opening pages with images or group or user streams - simply it takes way too much time making browsing almost useless. I don't know what may be the problem, but I logged out from other devices and cleared history and cache several times and nothing helped. Any ideas or similar issues?

I use mozilla firefox as my main web browser, and youtube sometimes does sometimes doesn't load (picture below). This happens only on firefox. Every other website works fine tho.

I am having a problem with my Firefox homepage. There are several things going on like the red, yellow and green dots on the left side of the menu change to light dark. Some of My Bookmarks appears twice and one was added. I did a Refresh and troubleshooting but to see if my home page would go back to normal but it did not. I think I have a bug that is causing these changes on my Mozilla Browser. I need to get the browser back to normal.

Hi,

I've been using the following in userChrome.css for many years

1. menu_close { display: -moz-box !important; }

to restore "Close Tab" in the File menu, based on cor-el's response regarding restoring menu_bookmarkAllTabs here:

https://support.mozilla.org/en-US/questions/799856

This stopped working some time ago and I am finally getting around to asking why.

I do have toolkit.legacyUserProfileCustomizations.stylesheets set to true, and other items in userChrome.css are working.

I am using 121.0 at home and 115.0 ESR at work and see the same (i.e. no "Close Tab"), in both cases on Debian testing. I do see this menu item when using the keyboard to open the File menu.

Any idea why this no longer works?

thank you, Greg

I use firefox with duckduckgo as my search engine.Every search was becoming so slow so I went to settings and deleted cookies and site data thinking this would unclog things. Now I cant access any site. Is there a way to reinstate this data?

I have freshly install Manjaro system. On there I installed the Flatpak of Firefox. When I try to login into my Mozilla account for sync it doesn't load. See the screenshot. On my other computer it works without an issue. What can I try?

It's been a while, but I've seen this before. What causes this? Can i prevent it? The blank icons also appear next to the most of the affected addons in about:addons.

I was able to restore normality, at least for the moment, by disabling those addons, re-enabling, then restarting.

Hello

I am using Firefox with synchronisation mainly on 2 PCs and 1 iPhone (there are old iPhone and 1 raspberry Pi connected, but not used). I have noticed that at least for a few months Firefox password library on iPhone was missing some password I needed, but I could always look them up on either PC without problem. Usually i tried to fix this by manualy synchronizing Firefox on iPhone in settings, it always showed that it is synchronized. Today I have discovered that i have only 19 passwords saved on my PC - same as on iPhone, but yesterday there were much more (probably all, but I can not be certain). Oldest one was created on 30. 10. 2023. All other are gone, I have managed to restore some old passwords (cca 370) from october 2021. I have disconnected internet and WiFi, placed old logins.json and key4.db in current profile, opened firefox and exported them. Once internet is restored, all passwords are deleted again, only those 19 recently created stay.

I did not delete any passwords or logins or anything on any device and did not delete any file or firefox profile. Why did it delete passwords without asking? And how can I prevent this from repeating? Because this is unusable password manager that randomly decides to purge login data from time to time.

thank you

Stuck with this hourglass logo on tabs since the latest update v121.0

https://imgur.com/a/k26XOm7

Now what I have noted is that this is causing the pages to load slow. Only ublock extension is installed, tried all dns settings but the result is the same. Is anyone facing the same?

These pages say to change the value and this hourglass thing will be removed

But I cannot see any option to change the value on that location

What to do now?

Hi, as seen in the screenshots, the toolbar popup windows are way too small. This goes for installing addons, websites asking for permissions, and remembering autofill information. It only seems to affect those instances, as addons pinned to the toolbar work as expected.

I've tried:

1. Clean reinstalling firefox (including deleting the Mozilla directories in AppData/Roaming + Local)
2. Deleting the default profile and creating a new one and launching with that
3. Deleting the xulstore.json file

The issue still occurs in troubleshoot mode, so doesn't seem to be an addon causing this. I also have the zoom set to 100% and font size as it was when installed; this is a fresh install still doing it.

This is similar to https://support.mozilla.org/bm/questions/1342630, except that was 2 years ago and trying those solutions did not work for me.

Any help would be appreciated. Thanks

hey, on websites like tumblr, hyperbeam, and other sites with video embeds or streaming, i keep having problems with the videos stuttering in one place and i usually have to refresh for it to fix. i don't have any extensions that interact with videos other than i guess ublock, and it only happens on sites where i do NOT get ads with videos. here's a gif of the glitch:

it's REALLY annoying, is there any known fix for this? firefox Version 121.0 (64-bit)

Merry Christmas 4 days Early!

I would like to stop the continual suggestion to update my password at login, yet be able to use the saved password at login.

Would you please add this fix?

Daniel

It turns out the copied logins-backupjson file i had pasted on my desktop screen was already overwritten by an added or removed login, thus writing over when it did have the saved login removed that i was trying to recover

is there any other way to recover the removed login?

i saw this response by Cor-el for another user with a similar situation

If you still have the signons.sqlite that was used in a previous Firefox version then you can try to restore passwords saved in that file.

Firefox 32 and later builds store the passwords in the logins.json file in the profile folder and no longer use the signons.sqlite file that has been used before (the matching key3.db file is still needed). If you still have the signons.sqlite file used in previous Firefox versions then you can try to force Firefox to migrate the passwords saved in that file (you will lose passwords saved in Firefox 32+ versions). You can force Firefox to reimport the passwords from the signons.sqlite file and rebuild the logins.json file with these steps:

   reset the signon.importedFromSqlite pref on the about:config page to the default value via the right-click context menu
   delete the logins.json file in the Firefox profile folder with Firefox closed 

When you restart Firefox then you should have the signon.importedFromSqlite pref with the value set to true and you should have the passwords imported in the Password Manager unless there may have been errors.

I have had two issues since transferring to Firefox from Chrome. Both result in error messages:

1. I have a Revolut bank account for which I get an error message (see below) when I try to log in. When I click the 'Restart Log In' button it retruns me to the orginal log in page with my name and on clicking this I am logged in. I have contacted Revolut support but they say the issue is with Firefox.

2. Other issue I have is that in trying to access some websites I get a messaeg saying that the site cannot be verified with a button to 'Try Again'. Once I click this button I can access the page.

I can work around these issues but they are annoying.

Hi All - I got a laugh out of the subject of this post, however it reads right. I have "Always ask where to save files" enabled. In the "About:Config" it does show Documents as the last folder. So oddly... lets say I download 3 files... The first 2 it will show Documents in the save dialog box and all I have to do is click save. Then the 3rd file it will default to dowloads for some reason. Ya I can just click Documents and click save, but that is irksome. Sometimes it will default to downloads for 10 save file attempts and sometimes it will just default to Documents 10 times in a row. Ultimately I don't want to have to check folder location each time. I will often "lose a file" and then remember I have to double check downloads, and sure enough it is there (because I forgot to double check, I just clicked save). I realize this is not the end of the world, but there does not seem to be any legit reason that I have found, that FF does this. Shouldn't it just do as it says it will do and the default location that pops up is the last location I saved to? Note this has been like this for years (I'm just now finally saying ENOUGH! :D )

Thanks!

Hello!

I can't figure out what setting to fix this: every time I click to open a new window, about 35 tabs automatically open up that I have closed several times in the past. I simply want one new window without any previously opened tabs.

I've tried:

• clearing my entire search history several times
• shutting down Firefox and reopening (which opens up all those tabs)
• uninstalling Firefox and reinstalling it
• initiating the latest Firefox updates
• restarting my computer
• turning my computer on and off
• looking through every single preference in my Firefox settings (I've unchecked anywhere it talks about opening tabs)
• reading various articles on Firefox's support page and on other support websites to try to figure this out (there's little info on this problem; the support is mostly about how to save previously opened tabs

Please help! I'm tired of having to close down all these tabs every single time I have to restart my computer or have to shut down Firefox. It slows down everything I'm trying to do.

Thank you!
