Firefox Community Forum

Hi everyone,

lately I started experiencing a font-family-related issue. On certain websites the font-families/styles look broken. I tried troubleshooting the issue by myself without any luck. What I did so far was reset my Windows fonts to default, reinstall Firefox and look what font-families are loaded through the Inspect tool. If I opened the same web page in Chrome the font looks OK. Two websites the issue is most visible at - support.fiverr.com and gmail.com when someone replies to my e-mail.

Please find below a screenshot of what I mean

Windows 10, Firefox 123.0 (64-bit)

It's so bad that I might have to stop using it entirely.

I've tried creating new profiles, disabling all add-ons, and disabling Enhanced Tracking Protection; none helped.

As you can see in the video (about the 00:16 mark) it randomly stops properly loading pages from the website, even in new tabs. The only temporary remedy is to either close and re-open FF, or press Ctrl+F5 (which I did at the end of the video).

I must add that it can happen even when loading the website for the first time in the session.

I need step by step on how to recover deleleted passwords

please do not respond unless you are going to tell me step on step what i need to do with loginbackupjson

Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.

I love how the new tab page clearly states "Never fear losing a closed tab again.", and then when a window disappears it is followed by zero history to recover it. I have not restarted Firefox, let alone my computer since the last time the window was seen (about half an hour ago). It's not in my Alt+Tab tray hiding. I don't even remember closing the tab--though it's possible my keyboard double pressed when I was closing another window. (It's old and has a tendency to double hit keys). But now I have lost a window with at least 20 tabs open--mostly things i had yet to deal with and don't remember the URL to get back to it.

What use is my history and ability to reopen accidentally closed windows if everything just disappears from it within half an hour after the window could've been closed?

I would prefer to keep most of my browsing on Firefox, but I can't constitute that if I'm going to lose months worth of saved tabs randomly.

I upgraded to 108.01 three days ago. It crashed 3 times in the next two days, accompanied by that popup you get informing you of the crash.

For years I've been using the extraction method of the executable to create a Firefox portable application. Upgrading only involves the install folder. The profile remains untouched, unaltered.

I had an incident of profile corruption a couple months ago, with basically Firefox launching with most features not working, i.e. toolbar buttons, toolbar menus, etc. Yesterday, for a short time, aside from two crashes, I had a similar experience with the buttons, but not quite the same. My default built in Firefox buttons worked, but my extension buttons didn't. I also noticed on a page that I regularly visit, Ublock origin wasn't doing it's regular job of blocking, and the Ublock button was non-responsive.

I'm also in the process of using the Brave Browser for the first time. The reason I'm posting this here about this subject, including a Brave experience, is that at the same time I was experiencing the Firefox erratic behavior, Brave was crashing as well; freezing; tabs not loading.

Considering the Brave tabs not loading, and the temporary Firefox Ublock origin failure, etc., I'm wondering if there might be something in common here? Maybe an internet connectivity issue at the time?

I have a new installation of Ubuntu 22.04 on my 2015 Lenovo IdeaPad 300. I have a new SSD HD 1 TB in size and it should work, however, Firefox keeps crashing. Other apps are crashing too.

I installed Firefox years ago. This morning, when I click on the browser icon, I get this message: Error platform '127.0.2' is not compatible with minVersion>= 127.0.1 maxVersion<= 127.0.1

What is going on? The browser updates itself so I don't do anything. But now, it doesn't work. I use an alternate browser to send this message to you.

In Firefox, the mouse becomes partially unresponsive to elements in the browser and on web pages. This happens after 15-30 minutes after starting up the browser. Common symptoms include:

- Unable to drag and drop elements properly, including text after highlighting it. - Sometimes, the mouse continues to hold elements while dragging. Pressing ESC temporarily fixes this. - Dropdown menus on websites do not drop down when hoovering over them - Other items on websites don't display items when hoovering over them

I have tried:

- Different mouses, including my laptop's trackpad - A Firefox fork, namely Waterfox, but it still occurs - Limited testing with other browsers. No problem occurs - Limited testing on desktop. No problem occurs - Entering Troubleshooting Mode on Firefox - Clearing cookies and cache - Reinstall Firefox (including installing from command line instead of the snap store) - Updated Firefox - Refreshed Firefox - About:Processes doesn't show anything using more than 10-15% of CPU at any one time - Limited testing with a new Firefox profile. No problem occurs - Disabled WebGL and Hardware Acceleration.

Temporary fix: Restarting Firefox, but the problem re-occurs shortly after use.

Using Ubuntu.

Any help would be greatly appreciated.

Firefox tabs start crashing all of a sudden and won't stop crashing, until BSOD happens.

In my case it caused PFN List Corrupt Blue screen error.

How can I identify the real reason for the crash of the tabs, leading to the crash of the system?

I saw a message that my Add-ons were disabled, and when I checked the Add-ons Manager , each of my many Add-ons had a message similar to: "1Password – Password Manager could not be verified for use in Firefox and has been disabled. "

Some searches in the forums suggest that that this can be caused my a certificate at Mozilla expiring, I seem to be the only one with this issue at the moment. All of my Add-ons came through the Mozilla store .

I am using version 123.0.1 (64-bit) on OpenSUSE Leap 15.5, and as far as I can see all of my updates are current (and from the official sources.)

What should I do next? I expect I need to wait for a certificate update or something at Mozilla, but if/when that happens how do I verify it did and re-enable my add-ons?

Ever since Firefox updated to the new version I've been having constant crashes. I've tried restarting in Safe Mood which doesn't help. Pretty much Firefox will open, say it's not responding, and then by the time it looks like it's about to restore my tabs it crashes. I had to do a refresh and transferred the backup files from an older session which worked, but then it eventually crashed again. I uninstalled and reinstalled Firefox and tried opening my older profile but it keeps happening. I really need to restore my previous session. There's nothing with my computer that seems to be causing it. I did have 2 windows open with about 8,000 tabs total which I'm sure could be part of the reason, but it never really had trouble before and only just started crashing since the update. Is there any way to fix this without starting over? I read that this is a bug that others have dealt with previously.

Some additional information. I'm on a 64-bit Windows 10 PC.

I'm a long time FF user. Version 121 works perfectly .

 Ever since 121.01 , updating breaks EVERYTHING.   Most of my add ons cant access their data, websites dont work, etc.  

 Not only that ,  but reverting to 121 does not help.   So the profile data itself is being trashed. 

 Restoring the full profile from a backup is successful, but only with version 121.   Any version beyond that breaks it. 

 I also tried a full delete and reinstall of Firefox, but that did not work.  Same problem.

 A full rebuild of all the add ons from scratch  might be my only option at this point if we cant figure out why this is happening.

Hi, I just replaced my SSD (Samsung 960EVO m.2 250Gb) for a larger/faster SSD (Samsung 980 m.2 1Tb) . I'm on Windows 10 and have 32Mb Ram. Firefox is now very slow on some websites (not all).

This example is typical and has occured on multiple sites. To test and compare, I copied the URL, created a new tab in Firefox, then Paste and Go. I timed this 3 times and each time was 30 seconds. I Pasted the same into Chrome and Edge and each time it was instant. https://savingschampion.co.uk/best-buys/personal/easy-access-accounts

On my previous SSD, there was never an issue of any lag on any site.

BBC.co.uk/news is fine, as are several other sites. Does anyone have any idea what's happening? This is making Firefox unworkable for me, so unless I can fix the issue, I will have to move permanently to Chrome or Edge. That would be a shame after many years with Firefox.

Thank you in advance.

When I run Firefox on Linux, the window initially starts at 1260x720 size. But when I try to maximize it, then the Firefox window size gets much larger than my screen's resolution. The maximized size is 2800x1600 size, my monitor is 1920x1200 only.

I tried different versions of Firefox and noticed this new behavior started with version 73.0, while it worked fine in 72.0.2 and versions before it. I even tried 73.0b1 and it has the issue already. I see the same exact issue when I tried the latest version 108.0.2 as well. It seems like something got broken in 73.0 unless I'm doing something really wrong.

Not sure if it makes the difference, I'm using MWM window manager on Linux. Please advise.

In Google Drive I cannot download a Google Drive Folder which is owned or shared with me. I get the error message Download failed/Zip failed. When I sign into Google Drive, I get a "There were some problems loading your apps" notification pop-up.

I have tried the same action in another browser (Edge) and it works. In firefox I have to resort to going inside the folder and downloading each file individually, which is painstakingly time-consuming.

Things that I have tried and it still failed to work:

• Restarting computer
• Different internet connection
• Cleared cache and cookies
• Delete all history and site settings
• Disabling adblock
• Disabling all extenstions and restarting browser
• Turn of ETP (Enhanced tracking protection)
• Switching strict protection in cookie settings to standard
• Adding cross-site cookies exceptions for google.com, https://googleusercontent.com, https://drive.google.com
• Logging out of Google, clearing cache and cookies, and signing back into account

Firefox browser 120.0.1 (64-bit) Windows 11

TO MOZILLA DEVELOPERS

In spite of hundreds if not thousands of users reporting this issue over and over again, and your suggested workaround to reduce memory usage in the settings that doesn't do anything - FIREFOX is still using unacceptably HUGE amount of memory.

With just FOUR (4) tabs open in one window, in the Task Manager I can see 17 (!!!!!!) Firefox windows open using 830 MB of memory. The highest usage of all my apps including memory hungry media apps. It's using THREE times as much memory as my Adobe Audition processing edits of a 1.5 hr audio with several clips.

This is insane!! You have gone crazy with caching to the point of making this browser unusable.

It's freezing up and crashing my Audition so before I work in it I must shut Firefox down completely - and I work on a powerful tower PC designed for media.

If you don't seriously cut back on this insane caching for the sake of browsing speed IN THE NEXT UPDATE, I won't be using your browser at all, it's simple as that. I'm already migrating my bookmarks and setting up Chrome which uses about half the memory that Firefox does with the same tabs, and I suspect that many users will follow suit.

The workarounds you offer DO NOT WORK. Any app that uses more than 500 MB of memory at any give time on my computer - goes.

I get this error when trying to access my email using FireFox. Lately this (or a similar) error happens weekly if not every couple of days. Always first thing in the morning, too.

my email works just fine using Safari so I am at a loss.

I have tried running FF (Firefox) in safe mode, ensuring outlook.live.com is an exception to the pop up window blocker, changed default protections on outlook dot com to none from standard.... Turned off ABP, clearing cache and cookies from within FF.

it may be worth mentioning that I can still browse/access other websites while outlook produces this error, and my network settings within FF are set to use default system settings (no proxy).

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.
