Hi,

I have the following problem: Windows 7 crashed after coming back from standby. When I restarted Firefox it restored a 3-month-old session. The sessionstore.jsonlz4 file was missing in the profile folder. I searched for a backup in the sessionstore-backups folder; unfortunately all were too old. Windows Restore was not running on my computer.

Using EaseUS Data Recovery I found a recovery.baklz4 file from 10 days ago, tried renaming it etc. but Firefox won't use it for recovering. It is probably corrupt ...

I used https://www.jeffersonscher.com/ffu/scrounger.html but I get an error saying: Session history file contents could not be read?

Is there any way to repair the file or extract the URLs to use them manually?

Or any other solution is very welcome! Thank you very much!

can't download files from any sites (it write eror....) i can dowland only from google wtf i live with this problem -+ 1 year if you need to write me i add my discord and telegram to images if you have some ideas to fix write me please. Thanks🤍

I am using Firefox 128.0 on Fedora 40. Whenever i am playing a youtube video its saying "An error occurred. Please try again later. (Playback ID: YfAmDqxb_Y3iWVfB) Learn More" I have no issue with ad blocking add-ons because i have Youtube Premium, so hopefully that's not an issue. I have tried few solutions from the forum , which were :

1. Unchecking "Use hardware acceleration"  Under Performance tab in Firefox
2. Using firefox safe mode
3. Refreshing Firefox
4. Deleting my cache/history
5. Enabling "Widevine Content Decryption Module provided by Google Inc." in my addons

But still i am having the same issue, its been 2 days, I am unable to find an appropriate solution to this. Kindly help me regarding this.

The integrated webcam (IMC Networks Integrated Camera, according to lsusb) on my linux laptop does not work in firefox (v124). It works in desktop apps (eg webcamoid), and chromium. I've checked the permissions (about:preferences#privacy), and that is not the problem. about:support does not list the device in the input at all. I've tried using LD_PRELOAD=/usr/lib64/libv4l/libv4l1compat.so, but that has not helped. Does anyone have any suggestions?

When I scroll down the page on MSN and try to open a link in a new tab the page jumps back to the top. It then opens a link of another article that I never right/left click on. I have my mouse set up to left click to open a new tab. Does not occur on any other sites.

It has been doing this for months now.

Videos stopped playing on Firefox today. I had no issues even this morning but starting a few minutes ago no videos would load and play. I am able to play videos on Chrome and no other video/audio issues. I restarted my pc and cleared Firefox cache/cookies but that hasn't fixed the problem. I am using Windows 10. Could you please assist?

Best, Steve

When I'm looking at a webpage, if there is a lot of dark pixels, the menu dims to a dull gray, and if it's mostly white it brightens to white.

This is EXTREMELY DISTRACTING and I want to turn it off. But I can't find a setting to disable this useless and annoying "feature".

How do I turn this off? Seems to be a new addition.

Hello, Since the last update Firefox 128.0.3, I can't add bookmarklet. There is one bookmarklet I regularly use on my main profile, wanted to add it to another profile, but it's not adding there. If I try to drag & add, it shows the new bookmark add dialogue, but nothing is getting added. If I try manual add bookmark from bookmark manager, still nothing happens. The bookmarklet is working fine in the main profile btw.. but can't add it to another. I looked in the browser console using Ctrl+Shift+J, it shows the following two messages repeatedly. `Places - Transactions: Failed to execute batched transaction: Error: Bookmarks.sys.mjs: insert: Invalid value for property 'url': "javascript:\"use strict\";function _array_like_to_array(arr,len){(null==len||len>arr.length)&&(len=arr.length);for(var i=0,arr2=new Array(len);i<len;i++)arr2[i]=arr[i];return arr2}function _array_with_holes(arr){if(Array.isArray(arr))return arr}function _array_without_holes(arr){if(Array.isArray(arr))return _array_like_to_array(arr)}function _assert_this_initialized(self){if(void 0===self)throw new ReferenceError(\"this hasn't been initialised - super() hasn't been called\");return self}function _class_call_check(instance,Constructor){if(!(instance instanceof Constructor))throw new TypeError(\"Cannot call a class as a function\")}function _defineProperties(target,props){for(var i=0;i<props.length;i++){var descriptor=props[i];descriptor.enumerable=descriptor.enumerable||!1,descriptor.configurable=!0,\"value\"in descriptor&&(descriptor.writable=!0),Object.defineProperty(target,desc…` and </p> `Error: Bookmarks.sys.mjs: fetch: Invalid value for property 'url': "javascript:\"use strict\";function _array_like_to_array(arr,len){(null==len||len>arr.length)&&(len=arr.length);for(var i=0,arr2=new Array(len);i

Hi to all the Firefox Browser Team, Since the last update Vs 128 on Ubuntu Vs 22.04 the whole computer freezes and I have to turn off the computer and restart it with the on/off button. It seems the last update didn't do me any good. Maybe Firefox got now too heavy for my system. As a Donator, I'm expecting a lighter Browser which my computer can be able to handle. I wish there was a light version of Firefox, now it's too much for me...I've downloaded another Browser named Falkon and my computer can make it work without freezing. If I get used to another Browser, I will not continue to use Firefox and then, will not contribute any longer... Thank anyways, I've used Firefox for so many years now but this is coming to an end...

Is there anyway to configure network.http.rcwn.enabled to false via the policy located in the ''C:\Program Files\Mozilla Firefox\distribution'' folder?

When viewing Foxnews website, I click a story to follow. When the new page opens, any next or video window goes black with no way to view the content. Does not occur with Edge.

YouTube does some kind of picture in picture thing when I'm watching a video and navigate to a different page on YT.

Is there a way in Firefox to disable/prevent this behavior? If not, is there some other way to disable/prevent this behavior?

(In Firefox settings, I have "Enable picture-in-picture video controls" unchecked. But I think that is referring to something else.)
