Firefox Support Forum

Firefox won't play YouTube videos. I've tried everything. There seem to be plenty of problems on the forum BUT NO SOLUTIONS!

I'm ready to switch browsers - permanently!

The most recent update, has caused my firefox to not work properly. Firstly i noticed that it reset all my extensions and themes and now i have noticed that it has affected some sites i was storing data on, for example, i use a site which keeps a track of all the camos i have achieved for Call of Duty MW3. This has now been reset. These can all be redone, but it is something i shouldn't have to do, with an update, as it has never happened before with a firefox update. The way it has been going, i am sure i will find more errors with firefox. Hopefully something can be done, maybe not in this instance but in future "Improvements", as it is not a good user experience!

Hello,

I use the Firefox browser on my phone and laptop, and have Lockwise on my phone where all the passwords are stored. Until yesterday, all these passwords would always appear in my Firefox browser stored passwords. Now, they only show up in Lockwise on my phone and do not show up in the phone or Laptop Firefox browser.

I have followed this guide: https://support.mozilla.org/en-US/kb/end-of-support-firefox-lockwise and am syncing passwords across devices, but this did not solve the problem.

Has anyone else encountered this and know how to fix it?

Thank you.

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)

I'm having the exact same problem as what was originally mentioned in this post from 4 years ago.

The "chosen solution" was to exit firefox through the hamburger menu, which I find to be absolutely ridiculous. You mean to tell me that even though I close EVERY OTHER APPLICATION either using the "X" close button or a custom keybinding that I've set for my own personal convenience, firefox requires me to exit through a menu every time in order to make it behave the way I've told it to? No. Absolutely not. If I tell firefox that I don't want it to save my last session, that means I DON'T WANT IT TO SAVE MY LAST SESSION. If I've deselected the "open previous windows and tabs" option in the settings, then under no circumstances should it be trying to open my previous windows and tabs.

I've tried the suggestion to change the value of browser.sessionstore.max_resumed_crashes from 1 to 0. The problem persists, I assume because firefox considers being closed using the close button to be a "crash", which is interesting.

I the other suggestion further down in the thread was to set browser.sessionstore.resume_from_crash from true to false, which will prevent firefox from recovering a session from a crash. This is hardly an appropriate solution. I want firefox to resume my last session if there is a legitimate (key word LEGITIMATE) crash, because my session was closed against my will due to something that went wrong. Being able to recover my last session in such a situation is nice. I do not, however, want firefox to resume my last session when I explicitly closed the last session myself, which would be the difference between a crash recovery and restoring a previous session. If no crash occurred, I don't need a crash recovery, and aside from a crash, I don't want my previous session to be restored.

Are there any solutions to this at all? Because this is one of the biggest reasons why I stopped using firefox. I want to come back to firefox because everything else that's worth using is either dog shit, or Chromium-based (i.e. also dog shit). However, I find this broken feature to be somewhat of a security issue. If a bad actor somehow gains access to my system, I don't want him to be able to open firefox and have access to my last browser session because I closed firefox using a keyboard shortcut instead of closing it through a goddamned menu.

previously FireFox was able to login Spotify normally, and was able to post comments on Reddit, but suddenly it lost both abilities, and with the extreme lag on other sites, although still functional, i can't understand why these both sites can't be logged into, or can't post any comments in them. it has been this case for the past month. so what's going on? i'm NOT going back to Chromium based browsers ever again! i am in FireFox for a permanent replacement!

thanks in advance.

The video from most websites plays out of sequence. It appears that approximately every one second plays its frames in reverse order. This occurs with most video streaming services and major sites. For example, all Amazon, Sam's Club, Walmart and other website product videos. Occasionally, Amazon product videos just say not compatible. However, YouTube videos with very rare excepts play fine in Firefox. Those problem sites play the videos fine under Edge for Linux. But, I would much rather use Firefox. I'm sure this a codec related issue. Possibly related to the NVIDIA GeForce GT 1030 video card in this computer running openSUSE 15.5. But after much searching, I'm at a loss on how to resolve the problem.

Hi, As of 2 days ago I am unable to load the above site in Firefox. I have a Windows 11 PC, a Linux Mint PC and an Android phone. It won't load on any of them but works fine in Chrome. I have cleared the cache and site data. Any assistance would be appreciated.

I am using Firefox as a browser to scrape data from Google Meet. However, while it works fine on Google Chrome, I encounter an error when using Firefox, which states: 'You can't join this video call.'

I have been using firefox mozilla to access our company EPM system for 3 years. It has been working fine but lately after I installed the latest firefox mozilla version, the horizontal scroll bar disappear in search results in the EPM system.

This did not happen when I use google chrome to access the system or Edge. It is clearly Firefox mozilla issue. Nothing is set in my preferences to make scroll bar disappear.

Hi, i have a problem with printing pdf in firefox. I have no option with orientation (rotation) only on pdf opened in web browser. On another site i can change rotation normal. In microsoft edge for example there is option with orientation on pdfs

Hello! Having happily used Firefox for many years, I'm now finding two related issues:

1) Firefox is automatically increasing the font size on webpages (not all webpages, but many, inc. Google searches, Amazon, the Guardian). I have to refresh the page to get it back down to regular size. For example: I do a Google search; click on a link; return to the Google search, and at that point the text jumps larger. It keeps getting larger until I refresh, when the process starts again.

2) My Yahoo mail is unreadable in Firefox. The text is either too big or unreadably small - even within the same email. For example: I open an email that is a response to one I sent; the text of my original email is really large, and the text of the response is really small (like, 5 points or less).

I can't think of anything that I did that acted as a trigger for these problems. My Firefox is up to date. I'm using a Mac, and running Ventura 13.4; I recently upgraded from Monterey and had both these issues on Monterey and on Ventura.

Any advice would be much appreciated!

I can no longer request further information on sites where it is possible to click and the result will be displayed. For example: I read a national newspaper on-line. After reading the article I then have the option of reading subscriber comments. When the button is pressed page says it is loading - but nothing happens. If I then switch to Edge - no problem. So I guess the problem does not lay with the newspaper. Many thanks for your help.

Our office uses a cloud-based database. Mozilla won't allow me to "check" boxes to do database searches for specific things. Google works fine, Edge works fine, but not Mozilla. Any ideas on how to fix this would be appreciated. Thanks!
