when I try to download a file, from a web link, with firefox, I see a flashing of the icons on the desktop wallpaper and then firefox hangs until I click on the application windows and appears the "not responding" message on the upper blue bar . The only thing left is to close the application by clicking on the x or by ctrl-alt-del and terminating. Same thing happens if clicking on "menù file --> open file" or it trying to Open file from the "Import and backup" button of the bookmarks library window. In addition, Firefox hangs also when clicking on the Menù "Options" tab.

A very similar thing happens with thunderbird when I try to attach files to new messages that I am composing: desktop flashing and software hangs and I have to terminate it. If i open preferences to browse the

I have tried many solutions for Firefox and for Thunderbird, including safe mode, OS safe mode, Refreshing, uninstalling both of them and reinstalling after deleting every profile folder to be sure to reinstall from schratch. I tried portable versions, uninstalled antivirus (at the moment I am running no antivirus at all ! ), updated video card NVidia quadro NVS440 drivers.

I posted a similar question about thunderbird on this forum here but I am getting convinced that the problem is about how mozilla products interact with explorer file dialog window since I essentially get the same problem when trying to work with files.

I saw a similar question here exept for the fact that I have thunderbird out of order too.

So far I couldn't figure out how to solve all this. Hope someone can help me because I have been using firefox and mozilla for more than 10 years now and would like to continue.

Thanks in advance. Bye

Hello,

I'm using an iMac, running the most recent OS (High Sierra, 10.10.3). After the recent update I'm experiencing a lot of lag with Firefox. If I open Facebook, for example, it takes several seconds to scroll, and it's unable to play two videos simultaneously. This is a new issue that I haven't experienced before. I've already reinstalled Firefox and deleted everything from the cache/cookies, but to no avail. I've also tried Safari and Chrome, and they don't have the issues.

Any help much appreciated.

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

I have read and tried several of the fixes for this but I continue to have firefox over a period of time use up to 6 gigs of ram. I have spent several hours on this and I just want to let mozilla know that I am going to give up and go to a browser that doesn't cause my whole computer to freeze up because of this memory problem. I have used and recommended Firefox for many years but I no longer fell like I can do this with the current version of firefox. I did not have this trouble before this version.

 I also do computer tech work and I will now have to recommend a different browser to my clients in case they have

the same problem as me.

 I dont feel that it should take several hours of trying solutions to see if I can fix something that is a problem I didnt have

until this version of firefox. So much for it being much faster and better, this is not my experience.

Not only I tried a fresh reinstall, I tried resetting all settings, safe-mode, rebooting, disabling hardware acceleration, upping the amount of processes FF uses, ALL the solutions the questions normally had... you name it.

This won't be solved by any of the other solutions I found here or anywhere else.

EVERY SINGLE TIME I open a new tab, FF Quantum (version 57, up to date as of today November 16th) freezes for 5 to 15 seconds. If I have a youtube video opened for example, the sound keeps playing (so the video is still playing on the "background") but I can't click anywhere or do anything, can't close the browser either if I don't open the task manager and shut down the process.

It's getting REALLY annoying, but I want to get a fix before I definitely decide to swap to Chrome. Please, don't make me switch to Chrome.

Hi there.

After years of not using Firefox, I decided to give it another try and installed it on my 13 inch Mid 2010 MacBook Pro. It's the latest Firefox release (63.0.3) and I notived that it is still a lot slower compared to other browsers. Pages loading slower, videos are choppy, and it also seems to use more power and memory.

So I decided to do some tests not to rely only on my observations, and it seems that I'm right. I'm using the latest Mac Os High Sierra 10.13.6 with SSd drive and 8GB of RAM.

I googled some browser tests, and I found this website: https://browserbench.org and ran all 4 tests available, and compared it to the latest version of Safari (12.0.1), the latest version of Chrome (70.0.3538.102) and here is what I found:

Firefox: Motion Mark: 49.13 Speedmeter: 21.5 Ares-6: 207.57ms JetStream: 62.505

Chrome: Motion Mark: 54.58 Speedmeter: 27.4 Ares-6: 72.39ms JetStream: 62.919

Safari: Motion Mark: 98.79 Speedmeter: 34.5 Ares-6: 58.29ms JetStream: 85.729

As you can see, the Firefox performance is rather poor, and it's been like that on my MacBook since I remember. I thought this new Quantum one will be much better, but I'm very disappointed.

Why is this happening? Why is Firefox so slow? I'd appreciate your thoughts on this.

Best

Opened Firefox one day, and soft-locked my system for several minutes. Killed it... repeated this process over a few days. Today finally opened it and just let it run to see what would happen. Ate all available ram. Then the swap. When it finally maxed both everything emptied out. System is now using less than a gig of ram and about half a gig of swap for everything.

Any idea what just happened and how I prevent it from happening again? I will also note - I have a lot of tabs.

OS: Windows 7pro Sp1 64bit History: About 3 updates ago Firefox started to randomly hang when I entered text, such as text in Gmail or in search engine windows. Or while filling out this help request. I tried unsuccessfully all the suggested remedies. I then uninstalled Firefox, and deleted any remaining references to Firefox and Mozilla in the registry. Finally I downloaded and did a fresh reinstall of the latest version. I used Febe to restore Bookmarks and Passwords. The problem continues. Details: Leaving Firefox by clicking on any icon on the taskbar or clicking on the desktop and then returning to Firefox restores the ability to enter text. Until the next hang. Amount of text I can enter between hangs seems random. It can be a few words or several paragraphs. When Firefox hangs the cursor stops blinking and the program becomes unresponsive to any input. Plea: Is there a solution or do I have to give up on my favorite browser and switch to Chrome or (gulp)IE? Thanks in advance for any help!

Running Windows 7 Pro x64, Intel core i7, 8GB RAM

Firefox 40.0.3 was hanging a lot when browsing eBay pages after upgrading. Removing all addons did not resolve the issue, nor did clearing cache or re-installing 40.0.3.

Re-installing 40.0.2 resolved the issue.

Some change introduced in 40.0.3 or possible eBay site upgrade is causing one of the top ecommerce sites to becomes unusable.

I recommend contacting ebay techs to resolve this issue if you believe the change did not occur on the Firefox end.

Additionally, when bringing up the task manager application, I see the ffcert.exe is running most of the time when the hangs occur. I never noticed this app previously, but that may be due to the hang not occurring so I had no reason to keep task manager open.

This has been an ongoing issue for a long time now, as long as I can remember. I click to open FF from my desktop, it opens fast, but hangs for anywhere from 4 to 8 seconds upon initial load before it even attempts to connect to my set homepage, which is www.google.com (I've tried other variations too, google.ca, google.com/ncr etc etc).

I've tried clearing my cache, completely reinstalling FF, safemode, disabling themes, disabling addons and re-enabling addons, with no luck, the same HANG persists.

Shouldn't FF load just fine and then immediately try connecting to my homepage? What's with this "Connecting..." every time I initially load the program?

I'm completely stumped here, I've tried everything,,,,, Something is causing firefox to delay at startup or it's hanging for no reason too long because it thinks the program hasn't loaded fully yet, but it has. Some sort of timing issue or something.

Please view the attached screenshot jpg file I've included with this post to see exactly what I see everytime I load FF for the first 4 to 8 seconds. I know computers and the inner workings of things and how to use about:config etc etc, so I'll be able to follow even the most difficult of directions if you have a solution. Thankyou ahead of time for reading this post, I look forward to your reply!
