Firefox Support Forum

Good evening. I'm seeking some help with an issue I'm having with Firefox.

As stated above, Firefox insta-crashes on startup. Hangs on opening in troubleshoot mode, then crashes after another 20 seconds and asks me to submit a report.

I believe this may have to do with the amount of tabs I had open when last using the browser. This morning I opened it up with about 7.8k tabs, and then closed it after adding another hundred. After trying to open the browser again, that's when the issues started. Until that point, the browser had been responsive and stable.

I've tried doing fresh installs of the browser and inserting the old data from the old profile, restoring to yesterday, and even trying without internet connection.

I have a Ryzen 5600X and 32GB of RAM, so I do not believe system resources are an issue.

Attached are some images. If any help could be provided, that'd be much appreciated.

Hello world! Is there any documentation explaining if FireFox Sync is the best way to merge different computers and/or devices with different logins saved? And if yes, how to use it (which computer log in first, etc). Has anybody done it and can explain if in the process entries with the same URL were duplicated or if the newer login information overwrote the older one?

I have found this question ALL OVER the internet (phrased differently) and yet, NOT ONE OFFICIAL ANSWER or an unofficial one that actually answers the question. Many well intended volunteers suggest to export and import but then again, there's no information on how the process works. (Duplication or saving Account #1 Over Account #2 or newer over older, etc). How can we get a an official answer? I am sure the coders know how their tool works... why is it so hard to help so many people in need?

For users who have been using FireFox in different computers over the years, it's a VERY REAL problem. Right now, I have to switch between my different devices when searching for passwords as I'm unsure what the Sync would do.... We should not be sorry for having chosen FireFox over other browsers... Thank you.

I installed Firefox on my new laptop (Same product, Windows 10) and now I keep getting the "The WidevineCDM plugin has crashed" error message on streaming platforms. I have reinstalled Firefox, restarted it, cleared my startup cache, and refreshed it to no avail. I have never had this problem before so I am not not sure what could be suddenly causing this problem.

Can't log into router. Works with Chrome and Edge 192.168.2.1

Tried this says in the router's Admin page: Access setting page via https://router.asus.com:8443 * Please use port 1024-65535. With and without :80 and :433

Tried everything I can find on this site and Google. Has worked for many years.

In Firefox 107.0.1 64-bit (Windows 10)

When looking at the console, the response tab no longer shows rendered HTML code - the response is blank.

Only if I select "Raw" over on the right do I see anything - only code.

Is this new behaviour from Firefox, or have I inadvertently changed an option?

The only way to now see the rendered page is through the "Network" tab.

Please see images.

I can't open amazon.com. I've disabled my antivirus and have tried in 'troubleshoot' mode. I have cleared my cache. I have flushed my DNS. It's been going on for days. I keep timing out. Other sites do not exhibit problems. Chrome DOES open amazon.com quickly.

I'm currently testing my website using FF's RDM, I have HTML 5 video with two sources, one Webm and one MP4 encoded according to the mozilla dev pages' advice on codecs.

The video, when clicking play or the video itself, advances one frame and pauses again under all User Agents bundled into Responsive Design Mode. If I click quickly and repeatedly it will eventually play properly. The thumbnail renders properly and the progress bar indicates that the video has loaded properly.

The video works as intended on Desktop (Windows & Linux), my Pixel 4a (FF & Chrome), my friend's S20FE (One of the UAs in RDM), and StackOverflow doesn't seem to have any input on my code, so the one last thing to check is with people who know more about Responsive Design Mode.

Hi,

as an admin I administer O365 web-sites/consoles in Firefox. I have two accounts in Firefox: my normal account, and my admin account which has far greater rights. The problem I am having is since I have enabled the option "Allow Windows single sign-on for Microsoft, work, and school accounts" (https://support.mozilla.org/en-US/kb/windows-sso?as=u&utm_source=inproduct), I always have to confirm two times that I want my admin account to login to for example: https://admin.exchange.microsoft.com/#/ Is there a way to tell FF that I want only the admin account to logon to the specified link so I don't have to select the account every time?

Thanks

Is there anyway to set a timeout on the Primary Password? It would be helpful if there was a time limit on how long passwords could be used before having to log in again. At the moment you have to close out of Firefox to lock it down again.

This is my website. I am developing a game engine however it is quite problematic that on my pc they display the old first version of the site, some error occurs and it displays a copy of the site downloaded somewhere in the memory of the PC apparently it is not very pleased. Fortunately, on a MacBook, your browser does not throw this away. how do I protect my site from firefox not displaying a page that no longer exists? I attach a photo on it of the old appearance of the site that it displays to me and I am sure that by going here (http://srv182659.hoster-test.ru/) you will not see this.

Это мой сайт. Я разрабаываю игровой движок однако довольно проблематично то что на моем пк они отображает старую первую версию сайта, происходит какая то ошибка и он отображает копию сайта скачанную куда-то в память пк видимо это не очень радует. Благо на макбуке ваш браузер такого не выкидывает. как защитить сайт от того чтобы firefox не отображал уже не существующую страницу? прилогаю фото на нем старя внешность сайта которую он мне отображает и я уверен что перейдя сюда ( http://srv182659.hoster-test.ru/ ) вы увидите не это.

More and more websites are alerting me that they are not fully compatible with Firefox and that I should instead use Chrome, Safari or Microsoft Edge. Recent examples are Allstate Insurance and Hewlett-Packard, not exactly insignificant players in the business world.

Here's what Allstate had across their page when I was attempting to log in:

"You may not be able to use certain My Account features on your current browser. For the best experience, consider using the latest versions of Chrome, Safari or Microsoft Edge."

There have been other websites with similar messaging about Firefox. The issue seems to be growing. Is there a fix coming from Firefox or are we going to continue to lose compatibility?

After updating to firefox 107.0.1 the bookmarks in the bookmark folders are separated too far . How do I decrease the distance? It now looks like they are in double space mode. Windows 10 is my operating system.

Hi folks. The title of this question started 2 weeks ago. Was fine before, but now a yellow triangle on the padlock.

Running test sites show everything secure. I have certificates. No other browser shows a warning. I read your help article and all is just like it should be. .htaccess redirects domain.com to www.domain.com and http: to https: just as it should. But still this "error". It must be images in my header, footer and sidebar, but I cannot change the path for those in any way I can find.

How can I correct this?

Thanks!

I don't know why, but I suddenly have a 'pop-up' asking me to have Google store login passwords to various websites. I've removed and deleted or uninstalled every Google app and software that I can find from my PC as well as my laptop, and do not use the Google search engine, nor any Google applications, so how do I stop this, and how did it even get into Firefox? Trying to create as much of a separation as possible between me, my computers and Google (if that is even possible).

I will repost this every so often until I get SOMETHING to help with this,or I get banned from asking questions (If that's even possible). THIS IS GOING TO DRIVE ME INSANE. I have to adjust my volume when unpausing something because it's too quiet, but then I have to adjust it AGAIN because after it unfades, it's too loud. I KNOW THIS IS PROBABLY A FEATURE, but I don't care. I only have this problem with Firefox, so if there's no solution I'll probably switch back to Google Chrome. I JUST WANT TO KNOW HOW TO DISABLE THIS, I DON'T KNOW HOW TO USE about:config, AND IT'S NOT IN SETTINGS.

The minimum tab width build into Firefox is 50. I'm used to much lower from Chrome, and would like it to be lower. I have many tabs open at the same time, and being able to see them all is what I'm used to. Instead of having to scroll for long time, it's really annoying! I saw a post that there used to be an extension which let you do this, but it stopped working with an older version of Firefox. Any help is greatly appreciated. :) Have a great day!

how is it that the usps website works on edge, but not on firefox? usps stopped working about a month ago on firefox. i already tried clearing the cashe and cookies from usps and that did not work, and neither did turning off ad block plus. im at a loss here.

Hello,

I recently did a clean install of my Windows 10. I was signed in to Firefox before formatting and had sync enabled for all fields, so I thought that once Windows was reinstalled and I installed Firefox I would get all of my history/password/bookmarks back.

Unfortunately, I've now signed into to Firefox and see none of my history/passwords/bookmarks. Is there anything I can do?

It would be quite devastating as I don't have any of that information anywhere else. I should've done a backup, but again, I assumed Firefox Sync would do that just like Google Chrome does.

Thank you
