Hi My firefox freezes when i open this youtube video https://www.youtube.com/watch?v=QAU_8GEgSwI

I cant do anything in the interface which goes glitchy after a while, forcing me to shut it from task bar and restart. It took me a while to understand the problem was with the youtube video. If i dont open that link, everything works normal. Also, Earlier (till yesterday) i was watching that video without any such problem.

I tried updating and reinstalling firefox completely but still facing the same issue with this particular video. I cant figure out whats the problem !

Please help.

Hello everyone,

I have an issue with firefox when I try to download files (ex: pdf, etc...) When I click on the link, I have the popup that appear to display if I want to open or store my file in the folder. And it's the moment that Firefox freeze (I try to select radio button answer for example and I have to wait 1 min for example before I can do it)

I have tried to start from a fresh profile.

I have the latest version 64.0 of my browser (on Linux Mint)

Do you have any idea of how I can fix the issue ?

Thanks

Just for the past few days 12-19-18 or so I've noticed this happening. I'll get an email, click "print" and it will open the email in a pop-up window. I select "Adobe PDF" as the printer, and then a window usually comes up showing the progress, and then it opens the pdf in Adobe Acrobat.

Recently, however, when that window comes up and shows the progress bar, it freezes. Sometimes I get error messages (shown in screenshots) but mostly I have to go to Task Manager, shut down firefox.exe processes, and I can't print the file to a PDF at all anymore. When I use this feature in Chrome, it works fine. I mean, it used to in Firefox, too, I don't know what changed.

Whenever I am using Fire Fox after about 20-30 minutes the menus (even the main menu icon), function pop-ups (e.g. click on the print icon to get the print pop-up asking number of copies, click on a download icon to get the pop-up asking destination), etc. stop working. This happens all the time independent of what site(s)/tab(s) I have open at the time. Tabs still work (a new tab will open). Sometimes I am actively using Fire Fox at the time, other times it is open but not my active window (in this scenario when I return to make it the active window again I find that the problem has occurred). Once in a while it will try to open something that generates an error message (NS_ERROR_FAILURE):

JS frame … contentCache … js::ObjLayerActionGoToNewWindow::line 7 data:no

In this case it was trying to open a survey window at the end of a course I had just completed. Most of the time I don't see an error message - just an audible ding and nothing happens.

When this problem occurs I have to completely restart Fire Fox to clear the problem - for another 20 minutes.

I've tried clearing the browsing history, turning off hardware acceleration, making sure pop-ups are enabled, and installing the latest version of Fire Fox (63.0.1). I'm not sure what else to try.

My laptop is Windows 10. According to Fire Fox these are the installed plug ins: OpenH264 Video Codec provided by Cisco Systems, Inc. Widevine Content Decryption Module provided by Google Inc. Shockwave Flash

Using FF 64 on a Win10/64bit.

All other browsers work fine (IE/Chrome/edge) i think (!) after windows10 update (the 'october update') i just installed since PC just came out of box... it stopped working. PC has been on and used with FF for few days already, had no problems, synced bookmarks fine etc.

Now: - no url loaded if entered manually - no url loaded if selected from bookmarks - no settings page loaded most of times. - sometimes (!) i can load "options/preferences" - i can never load about: functions

Checked and done so far without luck: - re-install (removed, restarted, checked for removal of Mozilla directory, installed) - created new profile - checked proxy settings in settings : manual / no proxy - checked windows firewall settings and even defaulted them etc - started in 'safe modus' (no extensions loaded) - not using 'offline' modus

anybody? i've spent a few hours now and near close to leaving it and using Chrome...

I'm using adobe flash on manual activation and it's causing Firefox to hang indefinitely. Disabling Hardware Accel cause Firefox to be unusable. Please help. I have no idea what went wrong.

When trying to add a site to the exception list firefox crashes as soon popup exception button clicked!

The browser simply freezes, no error message, its just stuck. Only way to recover, force close firefox.

The issue even occurs when Firefox freshly opened.

This one is hard to pin down, but occasionally Firefox will go unresponsive but will accept one previous mouse action (like clicking a tab) when I put Firefox in the background by clicking another open non-Firefox window and bringing it to the front.

How this happens:

1. I lock my macbook and step away from the desk for an undetermined amount of time. 2. I come back to my desk and unlock my computer. 3. I click on firefox to browse for something and it doesn't respond 4. I'll click another tab that isn't in focus, nothing will happen 5. I click on any other open application and I will notice that Firefox will change to the tab I had just clicked on 6. If I go back to Firefox, it will not respond to anything until I bring some other application to focus.

Sometimes, if I wait a long time like 10 or 15 minutes, the problem will resolve itself. Usually I just get frustrated and close Firefox.

I feel like this has to be a problem between Firefox and some other application that I run. Some other appications that are typically open are:

iTerm2 Spotify Lastpass Plugin Microsoft Outlook Atom.io Sometimes TweetDeck Maybe another Firefox profile

I have been unable to regularly reproduce this issue, but it will typically happen multiple times a day.

One other behavior that I have noticed is that I can click the address bar and nothing visible happens, but if I start typing, the suggestion bar will pop up and accept the text I am typing. I am including a picture of that behavior

Every week - EVERY week, I get notification that I need to upgrade FireFox. If I refuse to do the upgrade, FireFox refuses to work after about 4-5 days. The longer I go before I bow to the pressure, the LESS FireFox actually WORKS. Right now, I'm trying to read an email message. FireFox has basically shut down OTHER than this page. Anything else? Nope. I am seriously considering going back to the despised IE. I hate Windows, but this is SO ANNOYING! Shouldn't I have ANY say as to whether or not I WANT to upgrade? Because I am denied that choice. I either DO it, or FireFox will refuse to work. Thanks loads. Every upgrade, I spend DAYS getting things back to where I want them. I just get them right and I get notice of ANOTHER upgrade. Why not wait until you get it RIGHT??????

Hardware: Lenovo Ideapad 100 Laptop, i3-5005U CPU, 8GB RAM. Software: Arch Linux OS, Kernel 4.19, Firefox 63.

Issue: While using Firefox, the system freezes completely, forcing a reboot. This happens randomly, and may be minutes after launching the program, or spaced by a few days. It is especially common while watching videos on Youtube (If I open several tabs with one focused on a long video on Youtube, it is very likely the system will eventually freeze) but it has also happened when trying to switch tabs, opening firefox's menu, and scrolling.

What I've tried: Reinstalling Firefox, creating a new places database, disabling hardware acceleration. I use no extensions. After each of these tweaks, the system has eventually frozen at least once. I have tried stressing the system's CPU and -virtual- memory for a while in two separate occassions using the STRESS program, with no freezes. Temepratures always stay below 65C. I have also tried "stressing" the system using two other browsers: Opera and Chromium. Opening many sites in tabs, with one focusing a playing video on Youtube, and letting it run for a long while. No freezes either.

It might be related to this issue: https://bbs.archlinux.org/viewtopic.php?id=236686 but for me it has only happened while using Firefox, and no other program like LibreOffice, Chromium, Opera, PCManFM, stress, etc.

Is there any way to fix this? It is very disappointing as I much prefer using Firefox than any other browser.

Sometime in the past 3 months, when I use Replay Poker's site almost every time, or occasionally when I use Angry Birds Friends on Facebook in Mozilla (both use flash), and leave a poker table or the ABF game, it freezes my Mozilla browser. When using Replay's site this happens 8-10 times out of 10. With ABF, it happens 1 out of every 5-6 times I use it. I am unable to click on or in the browser window, and cannot close the browser with the x at the upper right of the window. The only thing that works at that point is to hold my mouse over my Mozilla icon in the taskbar, and when the small window icons pop up, I can close them using the x on the small icon. What seems to reset the browser is if I have two or more tabs open, and click the upper-right x while mouse hovering over the taskbar icon, getting the "close multiple tabs?" warning. If I click no, then the browser usually seems to reset and start operating normally again. Though, sometimes that still does not allow me to open a new flash window, so I have to completely close Mozilla and restart it again. I have noted a couple other mentions of this problem, but have yet to find a solution that works.

My graphic card drivers are updated. I am using the most updated version of Flash as well.

Allowed Firefox to download latest update to Firefox on 11/18/18. When I started up Firefox on 11/19/18, my PC would not respond to any inputs (running Windows 7 Pro) and my only option was to power down my PC to recover from the Firefox update hangup. What can I do next to recover Firefox and my hundreds of bookmarks I stored under Firefox?

FF 63.0 64 bit

Freezes randomly when open. Most of the time, its when some audio or video playing. Happens after a while and when moving the mouse.

Have:

turned off acceleration, re-installed, refreshed, turned off add ins.

Nothing has worked.

Please advise, I have also submitted crash reports, but have not heard back.

I find that often when I leave a tab running an application, eg. gmail, open another tab, work with it for a bit, and then return to the previous tab, theoretically still open, just inactive, Firefox hangs. The only way to get it to stop is to delete the tab and reload the application, again eg. gmail. I am on an iMac running EL CAPITAN version 10.11.6. Recently reinstalled Firefox after using Opera and then Safari for many months.

Like the title say, everything works just fine, sites are loading and working properly, then all of a sudden nothing is loading anymore, but I'm not getting any errors either. The sites are just loading forever, while in other browsers, Chrome, Edge and IE11, everything is loading perfectly. Sometimes this problem is fixed with a browser restart, but most of the time it's not. It starts working again just as it stopped, suddently and without any reasons, sometimes after a couple of minutes, sometimes after more than a half of hour. Any clues about what can cause such a behaviour?

PS. This behaviour started around version 60, and it occurs with or without plugins installed. The problem persists even when restarted in safe mode.

Since Adobe flash upgraded today, Firefox will not go from one place to another without locking up. If i try to close window, it closes but when I try to go somewhere, it tells me Firefox is running and do I want to close..If yes, it closes and I can go to desired bookmark..but again when I try to go to another bookmark Firefox locks up and the process starts again. Any suggestions..W10, Firefox all up to date..Adobe flash enabled. Deleted all the cookies too.

Upon install, I get message 'Firefox has stopped working'. 'A problem caused the program to stop working correctly.' 'Please close the program'. But the program never opens. I just simply close the dialog box.

Since the last couple of days, I see that Firefox holds a lock for places.db for the whole time while Firefox is open. The problem manifests itself when I use alfred workflow to do a search for a firefox bookmark by a keyword. I see that the workflow written in Python crashes with

`sqlite3.OperationalError: database is locked`

When I close Firefox, the script is working fine. When I open it again - the script is not operational again. Tried safe mode - the same result.

This was working fine for years and the symptom points that it was changed recently and now Firefox holds a lock during the whole time it is open. I guess previously the database lock was acquired per bookmark write transaction.

FF 63.0 macOS

Is it a known issue? Why was this change made?

Thanks!
