Firefox Support Forum

Hello! I updated FLOORP on the 5th May, FLOORP crashed and then Brave, Firefox, Waterfox, LibreWolf and Vivaldi started crashing. I had Brave and Vivaldi open when I launched FLOORP and FLOORP asked consent to update itself and after updating, it did not open in “previous session” and I could not open “previous session” through History. When I launched “Settings” from menu, “previous session” opened! I had pinned “Settings” earlier.

Now the bizarre happens; suddenly LibreWolf launches by itself also without “previous session” and open tabs in Brave and Vivaldi disappear to single New Tab. After some tinkering, I was able to restore “previous session” in LibreWolf, Brave and Vivaldi.

Now I close all browsers and open Firefox, no “previous session” and some random windows in its history, opening these random windows also opened “previous session”! 🙄But then Waterfox launches also without “previous session”, here clicking on OneTab extension recovered “previous session”.

Cutting short; I uninstalled, Waterfox, LibreWolf and FLOORP, this did not help, I ran System Restore twice to two different points and it has not resolved the issue.

Thankful for any help!

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

Firefox automatically updated itself to version 126.0 (64-bit) and it was unable to display any web sites.

First I disabled Mozilla VPN but that did not fix my issue. Next, I disabled Microsoft Defender firewall software to no effect.

Finally I updated the shortcut to Firefox on my taskbar to launch the browser. This fixed my issue.

Hopefully, this will save other users from the same pain.

I've added https://x.com as an exception site but it is still blocked.

This is outright censorship which is something fascists do.

Tell me how to fix your browser so I may access x.com again or I stop using Firefox forever.

I had issue with notifications (showed up but when i click on them they didnt were redirecting to original tweet) so i cleaned cookies after cleaning cookies i doesnt have option to turn on push notifications.

확장프로그램을 설치했는데, 원래 대로라면 브라우저 상단 주소창 옆 도구 모음에 설치한 확장프로그램의 아이콘이 나타나야 하나 나타나지 않고 있습니다. '도구 모음 사용자 지정'으로 들어가서 직접 추가하려고 해도 추가할 수 있는 아이콘이 나타나지 않습니다. 이 외의 방법으로 사용할 수 있는 방법을 아무것도 찾을 수가 없는데 대체 어디서 어떻게 찾아서 어떻게 사용해야 합니까?

Hello, about 1-2 weeks ago a very strange problem occurred - on some pages videos don't play at all or play without a sound. Can anyone help me with this strange situation? For example, every video on youtube.com plays without a problem; on facebook.com every video plays with no sound at all; on some other pages video doesn't play at all. This problem is only with firefox, if I try to open the same videos with another browser everything is fine.

Hi,

The Lower Toolbar is quite handy, with for example Roboform.

Unfortunately, the way it's implemented, it comes above the lower part of the browser window, instead of being inserted at the bottom while the browser windows height is reduced.

That hides the search box when you type Control-F.

It would be nice if this could be addressed in a future release. I am using Firefox Developer 127.0b2.

I recently had to reinstall Windows, as a result of a hard drive issue. This involved reinstalling Firefox from scratch.

As such I had browser.sessionstore.resume_from_crash set to false, but browser.sessionstore.max_resumed_crashes was still set to its default value of 1. The combination resulted in a browser restore after a crash...

This would seem to imply that browser.sessionstore.resume_from_crash has either been deprecated (though that is not mentioned in the knowledgebase article), or it is not being correctly interrogated in the code. Unless I am missing something, and I do not want to go thru the entire config to see what else I might need to set...

If I am reading this wrong, please let me know if there are other entries that need to change from default. In the event of a crash, I want the browser to start with my home pages, NOT restore.

Currently on FF 125.0.3 (64-bit) - and yes, I know there is an update waiting for me to restart my browser yet again...

Hello there, for past few days I'm having issues mainly on Twitch.tv - the streams do work fine, but whole website is displayed as text - Avatars, emotes, badges are displaying as text, or don't display at all, I'm attaching screenshots as examples. What I've tried - restarting PC, router, full re-install of Firefox, disabling all add-ons and uinstalling them (7tv and FFZ), private mode, troubleshooting mode, creating a new profile in Firefox, checked firewall settings, checked AV settings and did multiple scans - nothing was found, tried changing Firefox security Settings, also cleared cache and cookies.

I think that's everything - I was doing everything that was in the article: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems

Regarding other websites - this is completely random, mail works, some websites also do, but on some it gets stuck, like for example when I have to do a 2FA somewhere and get a pop-up window to click "login" or type a code, it just gets stuck and nothing shows up.

Not sure if this helps, but exactly same issues appear on different browsers - Chrome, Edge, but only on PC. I tried Firefox on mobile and it worked just fine.

If I can provide more details please let me know, I did attach the "Troubleshooting Information" so hopefully this also helps.

Thank you in advance!

I use the Kindle Cloud Reader (https://read.amazon.com/kindle-library) to access and read ebooks in my Amazon Kindle library. Since the latest Firefox update something is preventing my ebooks from opening correctly. The ebooks open, but only a single page appears and none of the navigation controls load.

Amazon support suggested trying a different browser. I loaded the Edge browser and had no problems opening my ebooks. I prefer to use the Firefox browser so I hope you can fix this issue.

Please help.

So yesterday I downloaded a bunch of files to mod a game. This warning appeared and since then it's been popping up every time I start the browser. I have cleared all cookies related to the relevant sites. I have removed the warning about unwanted and uncommon software. I would rather not clear all my cookies and data to resolve this, so looking for other suggestions first. I don't mind digging through files or code to make it happen.

Hi,

My Mozilla Firefox Web developer tool keeps autonomously toggling on/off in any Firefox window/tab..

Its as-if I'm repeatedly hitting Ctrl-Shft-I (which brings up the web developer tool in the bottom 1/4 of the browser).

I've checked all Setting, turned off all hardware acceleration as suggested for similar flickering problem (which wasn't on anyway).

I use Norton 360 Security Software but have Norton Safe Web disabled. The only active Extensions are Firefox Multi-Container and Firefox Sideview.

Its not doing it at the moment, but I'm not sure exactly what triggers it and expect it to happen again.

Last time it happened I was browsing Amazon. Hitting Ctrl-Shift-I only makes is turn off until start scrolling again, etc.

I don't think its virus related, because I use Norton 360, and Task manager "Performance Tab" show the computer is generally very mellow.

Please help, as I love Firefox, but this problem can drive one crazy.

Thanks Larry Zdanis

Every time I start up firefox, it takes about a full minute to load. It shows an outline of the UI, but does not become usable for a while, windows also puts up a "firefox is not responding" window when the window is interacted with. After loading, opening a new window is unaffected, and page loading is snappy. just the initial launch is the issue. This remains true even after a clean uninstall + reinstall. Appdata folder was removed as well, and did not affect the issue. I do not have any antivirus software other than windows defender, so that should not be an issue. My hardware is also not likely to be at fault, as it is sufficiently up to date (upgraded within last year, not sharing specs here). Chrome starts up in less than a second for reference. Once again, a fresh install with a new profile has the same symptoms. Have tried every available guide to no effect.

I have a PC that cannot access the Internet. Using a thumb drive, I was going to download Firefox then load it onto the PC. Do you think this will work and if so, how do I put Firefox on the thumb drive (be specific - step by step). Thank you

There are some pop-ups I cannot stop.

Naturally, I have clicked “stop pop-ups” in the Privacy and Security section of Firefox Settings. That has worked but not quite. I keep getting some “via l-itineraire.com”. That’s a website I used during a recent holiday in France.

So I installed Block Site.

That has an option called “Block a new host name”. I entered “l-itineraire.com.” and clicked Add. This has had no effect. The pop-ups still arrive from them.

I know there’s an option to open the website and get into the Firefox toolbar, but that’s defeated me. Yes I managed to get to click Menu, but not beyond. Anyway, that should not be necessary – after all I’ve clicked no pop-ups.
