I-Firefox Isithangami Sokwesekwa

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

YouTube videos not working with Firefox since recent updates. Videos start to load but don't don't complete. Firefox is the only browser with this issue. Have tried three other browsers without issue.

When downloading files, Firefox no longer remembers the directory path the file was previously saved to on a per-URL basis.

Previous Firefox behavior: #1. download file from website "aaaa.com" to a folder on your computer, "user/frank/companies/aaaa/". #2. download file from website "bbbb.com" to a folder on your computer, "user/frank/companies/bbbb/". #3. Now, go back to the website "aaaa.com" and attempt to download another file. Firefox used to present the previously used directory for this particular URL, in this case, "user/frank/companies/aaaa/" - but instead, now it presents the most recently used directory path, which was "user/frank/companies/bbbb/".

This issue has appeared before and the advice to fix it was to go about:config, search for browser.download.lastDir.savePerSite and make sure it is set at TRUE. I have done this, but the issue remains: Firefox no longer remembers saved file directory paths on a per-URL basis.

MacOS 11.6.6 (Big Sur); Latest Firefox (103.0.2) Attempts to fix: Safe Mode - issue still present; Refresh Firefox - issue still present

Is there any advice on how to fix this problem? - Thxs.

Upgraded to version 101.0 after getting the pop-up prompt and now every site I visit is taking at least twice as long to load and display compared to yesterday. (Even this support site!)

It has to be something in this release and not my connection, because:

• My mail client is completely unaffected and is behaving normally.
• I tried accessing the sites that were loading/displaying slowest using Opera, and they loaded as fast as they had in Firefox previously.
• Nothing else that uses my internet connection is working any differently than yesterday.

I also cleared the Firefox cache. No improvement.

It's not my add-ons because the only one I have installed is uBlock, which is recommended in various help articles here at the support site.

Nothing in the knowledge base has proven helpful.

Is anyone else having this problem? Is there some tweak I need to make in about:config to fix this? Or is this another case of "wait until the next release", yet again???

I recently made the switch to Firefox. I attempted to use the version downloaded from the internet, which I already had installed for a long time, but it would not open. I then used the version available on the Microsoft Store, which worked fine. Eventually, Firefox crashed and would not reopen. A message saying something along the lines of "Are you sure you want to start Firefox in safe mode?" would appear for a split second, and then close. I tried:

-Starting Firefox in safe mode, but nothing happened. -Restarting my computer. -Reinstalling Firefox. -Running as administrator. -Checking it is not blocked by antivirus. -Using the profile manager to create a new profile: The .zip file version opens but does not help, and the version opened by using the "firefox.exe -P" command in Run suffers from the same problem as the browser and opens for only a split second. -Attempting to boot my computer in safe mode with networking, however, the Microsoft Store listed Firefox as uninstalled, and the network menu would not display any networks so I could not reinstall it. -Searching for any Comodo iseguard.dll files, but I found none.

The only thing that worked was searching "Mozilla" in files and deleting everything except what my computer said was part of the system. After that, I was able to open Firefox, but after a short amount of time, the problem started all over. I have no clue what to do and looking all over for solutions is driving me nuts! Please help!

How to reproduce the bug: Jump to the address bar, and then press shift, ctrol, alt or windows_start, you can see the address getting deleted. You can also see it in Google Sheets and Microsoft Excel Online, it just deletes the cell, or a selection of multiple cells. --Interestingly on Google Docs it doesn't delete but just move the cursor to the first character when a string is selected.

 It happens only once per mouse click, or focus change

What I expect: Shift, Control or any mod key should not delete content or move a cursor

Thanks!

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.

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Here is my system information

here

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.

Hello :)

Firefox 102.0.1 crashes after some Time. Firefox then is unable to switch between Tabs and stuck at the opened Website.

For testing Purpose i start over with a new profile and did not install any Add-ons. The behavior was the same, it crashes after some hours.

My System is Ubuntu Mate (Ubuntu with Mate Desktop) in Version 20.04.

Here has someone the same problem: -> https://bbs.archlinux.org/viewtopic.php?id=277649

Thanks for any suggestions.

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 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 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?

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.

Startup Crash False Process Type parent MOZ_CRASH Reason (Sanitized) Failed to load critical module "resource://gre/modules/WebNavigation.jsm" Crash Reason EXCEPTION_BREAKPOINT Crash Address 0x00007ffb8c0f5135

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?

I can't play a video when logged into a website - see https://support.mozilla.org/en-US/questions/1371380

I'm sure it is not Firefox as I have also tried Chrome and Opera; same problem. How can I debug this and find out why the video cannot be played ?

I see there is 'Remote Debugging' and 'Browser Console' under 'More Tools'. How do I use these or other tools to find out what is causing the problem please ?

Whenever I attempt to watch something on any streaming service, I get an error message from the streaming service and a note from Firefox saying "The WidevineCdm plugin has crashed." I have tried to solve this problem a number of ways, but have unable to find a solution.

My best guess is the problem is due to the most recent WidevineCdm update, as in the plugins settings the most recent update for the plugin was on 10/21/23, which is shortly before I first noticed the problem. I did test out various streaming platforms on other computer browsers (Chrome and Microsoft Edge) — they gave the same website errors as I got on Firefox, but those browsers did not indicate the cause or suggest which plugin failed. I additionally tested out desktop apps for some of the streaming platforms; they work fine without any issues, but unfortunately the main streaming platform I use doesn't have a desktop app and only works in browser.

My computer is a Lenovo Yoga 9i, it's running Windows 11, and everything is up-to-date.

The methods I have tried to fix this issue with, to no avail: - submitted crash reports - toggling the "play DRM restricted content" options in Firefox, and toggling whether or not the WidevineCdm was activated, closing the browser between each toggle of options - clearing Firefox's cache - running Firefox in troubleshooting mode to make sure it wasn't a different extension interfering with it - tried running Firefox in compatibility mode - tried to find support from the people who made WidevineCdm, but apparently they don't do end-user support - deleting the WidevineCdm manually from the program files for Firefox and Chrome (since Firefox says the plugin is from Google), and then reinstalling it via the chrome components page. This briefly lead to the message on the plugin page that WidevinceCdm would "begin installing shortly." It seemed frozen like that for a good while, but then I tried clicking the "check for updates" and that message disappeared, and it went back to crashing when I tried using a streaming service. - uninstalling both Chrome and Firefox, restarting the computer, then reinstalling both browsers

As far as I can tell, the plugin comes automatically installed in the browser, and there isn't an alternate plugin for decrypting DRM-restricted content. If there's a way to set the WidevineCdm to a previous version before the update that's crashing it, I haven't found it, but I am no expert in computers or coding, and my guess about it being caused by the recent update could be wrong too.

I'm at my wit's end here, any help fixing this problem is greatly appreciated.

Had it yesterday, happened this morning after the restart and just NOW, when I entered 6 lousy tabs, and they are NOT in the recently closed list either.. wups, gone, no tabs, setting has a check mark on open previous windows and tabs. Within 24 hours, lost the tabs three times with a non reported crash and Firefox closing itself with no warning.

I honestly do not think I am responsible to keep a backup of my browser history, I expect a browser to do that. I switched from Opera to Firefox not to long ago.. even Opera is a security risk.. at least it doesn't delete your tabs just for fun.

Very simple.. that happens once more and i am OFF this browser....

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.

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).
