Using PC with XP. Firefox had been working fine on this PC for a few years, Have had to fix a few times always before if needed by uninstalling completely if need be and starting all new,

Not this time, Have version 22.0 installed, no add on's since I reinstalled so should be clean install no ext or plug ins added yet, but it still does not run in normal mode, only in safe mode.

Some HTML5 videos won't play in my Firefox browser.

This vine for example (https://vine.co/v/b3v5h3Piwt7) only shows up as a static image. I can click the mute/audio button though, but it won't play. When I look at the webconsole when I load the page then 2 javascript warnings show up, the first one say that the Mediasource [long url here] can't be encoded and another one says loading of all candidate sources failed. loading media paused.

I'm using Firefox 21.0 and I tried to run Firefox in safe mode with disabled add-ons, and I also tried to reinstall it, but without success.

Thanks in advance.

I've been using Thunderbird successfully for years. I have three accounts on the same server at Time Warner, one of them is my main account. This account, in addition to the usual ones, has several custom created folders full of email. There has been a problem with the server, and I can no longer retrieve email for that account. (The other two accounts work just fine.) I've been able to log into that account via webmail with no problem. The techsupport advised me to delete and recreate the account in question and assured me that all my folders will be in place. I can't risk losing my email, so I'm reluctant to follow on that advise. Is there anything I can do safely and make sure that all my email is preserved? Thank you for your help.

Hello,

I've seen this problem listed several times prior to this post, but none of the solutions have helped me.

I've been using Firefox for ages and the last 3 updates or so have been exhibiting this issue. When I attempt to load a website, Firefox will begin to take me to the page and then hang. The circle in the tab will stop moving and it will sit there until I move the mouse or press a button on the keyboard. As long as the mouse is continuously moving or keyboard buttons are pressed, the page will load fine. The same thing happens with YouTube. The video will start and then freeze unless the mouse/keyboard is moved. Firefox also exhibits this behavior when I try to download a file from a website. The download will start and then hang until I move the mouse or press a button, then it will continue for a few seconds and hang again until I repeat the mouse movement or keyboard button press.

So far, I've tried updating Firefox, Java and Flash; starting Firefox in Safe Mode; uninstalling and reinstalling Firefox: doing a complete uninstall and reinstall of Firefox with profile removal and creation. I've run the following ad and malware detection tools with no infections found: Malwarebytes' Anti-Malware, AdwCleaner, SuperAntispyware, Microsoft Safety Scanner, Windows Defender, Spybot Search & Destroy, Kasperky Free Security Scan and Anti-rootkit utility TDSSKiller.

The only thing that I've tried that "seemed" to work was starting Windows in Safe Mode with networking and running Firefox there. I was able to watch YouTube videos without freezing and websites appeared to load properly. Obviously, I can't run in Safe Mode all the time.

I've attached a screenshot of what it looks like when Firefox hangs on Google News. Notice that the images partly load, but a good number of them are either waiting or not loaded.

I hope someone can help me, since I really like Firefox and I'd hate to switch to Chrome or (shudder) IE.

Thanks in advance for your help!

Just recently the info popups in Hulu stopped working ,have tried different settings in adblock ,but it may or may not work. I have not changed any settings and it won't work in safe mode either.

I hit bookmark this page and the window opens, 1st screen capture.

https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-09-24-23-47-06-d7aee0.png

Next I expand "other bookmarks" then "choose" See 2nd screen capture

https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-09-24-23-52-08-d9387a.png

When I click on "choose" see what happens in the 3rd screen capture.

https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-09-24-23-54-18-679698.png

I can choose the sub folder to save the bookmark to. BUT I now CAN'T scroll down the screen to hit the save button. Because the bookmark window doesn't have a scroll bar or a way to make the bookmark window smaller. This is frustrating. Firefox is having other issues not connected with this issue. But the overall picture is getting me to the point of dumping Firefox and going to Google Chrome.

Hello

I have spent 3 days trouble shooting this and can't resolve it. Firefox won't load pages, just get a grey spinning circle forever. No other message. I close firefox and restart, it won't start as it is still running in background. Task manager will not close it. I have to reboot the PC. I have tried deleting profiles, which helps for a few minutes then it locks again. I tried re-installing firefox and again it works for a few minutes then nothing. I have completely deleted all 'appdata' and still no luck. New profile doesn't help. I checked all security settings, firewall, etc. and nothing helped. I tried safe mode and the problem still exists. I have used firefox for years and now may have to walk away. Any help is appreciated. Thanks.

Ever since the upgrade of Thunderbird to 38.* I have had nothing but problems with Thunderbird stalling (spinning wheel waiting), a 'Mozilla Thunderbird (not responding)' in the header bar, the TB application window whiting out, and eventually the Box to Hell - a small box popping up asking if I want to - close the program, waited for it to resolve itself, or check the internet and then close. I now call it the Box to Hell (B2H - call it whatever you want but I am damned every time it pops up!)

I have done everything suggested here to do and nothing fixes it. I have been using Thunderbird for years with all the same folders and add ons with NO problem. From day one of the 38 update everything changed. When will Mozilla realize that it is in the upgrade and find the problem!?

Here is all that I have tried with nothing working... 1. I do not have AVG, only malware bytes and windows defender 2. It still happens in safe mode with no add-on activated. 3. I have stopped the saving feature which slowed the frequency of the stalling but did not eliminate the problem. 4. I have deleted hundreds of older emails thinking it was that but that did not do anything. 5. I changed some accounts from POP to iMAP thinking that was the issue but nothing changed. 6. I have made numerous attempts at fixes both on Mozilla Support and outside on the net. Nothing is working. In looking at all the people that have the same issues, I would have to say that the problem stems with the file handling. I have noticed this being the issue with others that have multi folders, and emails. The answer is not to reduce these volumes but to figure out why thunderbird handled them fine before and what has changed to make the program hang now? That has to be on your end, support. Keep us faithful followers and fix the issue....

Here are my particulars....

A. I have multiple folders and thousands of older emails for years and have manged them fine, as a matter of fact, Thunderbird has been awesome. Then like a good minion I trusted the moz and did my upgrade to 38. Never have had a problem before the upgrade. After the upgrade everything went to ****.

B. The version 38 upgrade was a big change. When I would look in the folder that was labeled the Sent or inbox folder(where all emails from each account is gathered), all the listed emails would disappear when I moved my mouse over them! Disappearing emails! They were there in the specific email folders below it but not but in the head folder like it was just a day earlier and with out the upgrade. I figured that as an add on issue and waited for the fix that happened not so long ago. Again, that may have been an add-on folder issue .

C. The upgrade to 38 had other issues but if going from no issues to craziness was not bad enough, the problem seemed to get worse with each 'update or bug fix that followed. Don't hold me to it but I think it was in 38.1.2 or 8 (I think that was it. I was not paying attention but had I known I would be having to recount this, I would have!) That is when the hanging got interminably long. When the program closed at least I had a draft saved, then I read on line that the saving of open messages was the problem so I turned the auto save off. It did change the frequency of the hanging (white screen pausing) and stalling (where the B2H pops up) but it was still there and still is!

D. I had hoped that with 38.2 there would be improvements. Nothing changed. I was sure that 38.3 would make that change/fix but nooooo. So I am writing all this so you have what I know as a faithful user since 2007.

E. Here is what you need to complete the picture. I am on a PC running 8.1. on an Intel i7-4770, with 32 gb ram, now you tell me when you will issue the update to fix the problem! Again, Mozilla, I would suggest that you begin looking at how TB 38 handles multi emails, folders and archives. Not all of us only have one email account. Most of us have been really happy with TB prior to 38. If you can't find the issue, can you show us how to go back to a version prior to 38?

Thanks for listening and hope all this helps!! @v@

I have updated my browser to 57.0 and when I launch it, it immediately uses 4 Gb of ram. After opening 1 or 2 tabs, it gets slower and slower and eventually stops reponding after a few seconds, forcing me to end the task. I use a few add-ons: Dashlane, New tab tools, uBlock origin, Disconnect, Dashlane, Internet Download Manager. Than you for reading this, i hope there is a solution.

This is a continuation of a thread found here: https://support.mozilla.org/en-US/questions/997448 by Compumind.

I reported I was having the same experience, especially when opening links from emails in Thunderbird. I also reported I was forced to revert to FF 28.

Moses replied in above thread and suggested: (1) Download a fresh installer from https://www.mozilla.org/firefox/all/ to a convenient location. (Scroll down to your preferred language.)

(2) Exit out of Firefox.

(3) Rename the folder

C:\Program Files (x86)\Mozilla Firefox

to

C:\Program Files (x86)\OldFirefox

(4) Run the installer you downloaded in #1. It should automatically connect to your existing settings.

I followed these instruction carefully but no joy. Upon installing FF 29, not only would it refuse to exit (using "exit") and remain running in the Task Manager until I killed it after opening links from Thunderbird, but I found it refused to exit after simple browsing and following links.

Moses had asked I not reply in original thread so I am re-posting here.

I believe this is a serious bug. With Firefox 28...no problems except a minor one I reported here: https://bugzilla.mozilla.org/show_bug.cgi?id=1002089

Again I am forced back to FF 28, though I miss the beautiful interface and security fixes, I need to have a browser that works properly. My wife has never even seen the Task Manager before so this is problem.

Besides the "educated guesses" made with this post, the only other thing outside of usual that I do, is to have a security policy regarding cookies (don't accept by default...I make exceptions for cookies I want to retain and have a several that are only "allow for session.") I also have FF set to delete browsing history on exit, but that takes a split second.

I look forward to when this issue can be addressed successfully and I am able to use FF 29 (and have it exit properly...I can't expect my wife to follow all these instructions and close it often manually in the task manager...nor do I want to do this.)

Good luck on all the Mozilla projects. Having installed FF 29 twice and then reverted back to 28 twice, I am going to wait and see how this plays out. Please don't send me the standard, "start in safe mode", "restart with add-ons disabled", "reset Firefox" (last time that destroyed my browser completely) stuff. I do not believe this is what's happening.

Moses added that there is a problem with email notifications going through, so take your time, friends.

Firefox presents no problems with popups in contrast with Thunderbird. In Thunderbird popup window for e.g. Tools or Settings opens in mini size and is elusive, unreadable and unclickable. For this reason it is, for example, impossible to print any email messages. Printing is no porblem with Firefox.

How to repair this problem?

Hi. I was having an extreme amount of slowness on FireFox Quantum Beta (version 57). I had the slowness just before and after a new update was installed (11/13/17 at about 10:45AM CDT). I captured the Task manager just before and after the update. I know that there is a legacy Flash plugin but it is set to never activate. How can I get rid of it permanently?

I have been using the Downloadhelper add-on for years on my laptop with no problem. I noticed about three days ago it was no longer working with any Youtube videos. The rotating icon is still working, and when I click on it, it still gives me the file type choices for downloading. However, after I click my choice, the green arrow shows the downloading process, but comes up '0 bytes' for every type of video.

I am not having problems downloading videos from other sites that I've used before, just Youtube.

Also, I am able to use Downloadhelper with Youtube on my other computer without a problem.

Can you please help? Thanks.

When I visit this site:http://www.apolloarchive.com/apollo_gallery.html I can no longer see the image thumbnails when I click on the image IDs. I contacted the site owner, and he said it worked for FF on his computer, but I'm afraid my javascript isn't working here. I did everything, cleared the cookies, ran Safe Mode, checked options- though i may have goofed. And I'm almost sure javascript is enabled here. I have Win XP. I don't want to check another browser; if the problem is here than it needs fixing. I'm waiting more word from the site owner, but I tried everything he suggested. So what do I do? Do I download another Javascript?

Ive tried everything in firefox so far but its just no working for me

i disabled addons manually to see whats gobbling up so much ram but nothing, i upgraded, downgraded all the plugins and nothing either (the new flash plugin was giving me issues so now im on an older one btw, was still having issues with recent flash version so thats not it) i added addons that supposedly reduce ram usage but nothing

i enabled and disabled hardware acceleration but nothing either

i cleared the cache and everything that firefox can clear except the browsing history but nada

i used speedfox to try and possibly fix this annoyance but nothing at all

i updated, downgraded, and basically did everything possible with my computer's drivers but nothing either

is firefox just meant to be like this and to behave like an app that never releases its RAM afters its used? in task manager its showing me anywhere between 1.2GB or RAM being used or over 2GB's!! this isnt normal especially since i have only 4 light tabs open, all this and to add to it the context menu loading when i right click is slow as molasses

please, please, can someone just help me here? i added a log thingy that could possibly help, idk whats even going on here anymore from this, one day firefox was great and using no more than 1 gb in total with over 100 tabs open but now with just 4 after firefox has been open for a long time its devouring a quarter of my total RAM, for a browser thats a bit insane, especially since in the days i used to use Opera itd use no more than 800MB at worst

Hi, The subject is sort of self explanatory but for the last few months (not sure exactly when) i have had regular Firefox crashes, it seems to happen when i'm out of memory and FF has used all the available RAM. I have a MBP with i7 and 8gig of RAM using the latest OSX 10.9.1 and latest FF 26. I always keep up to date with the software. Usually i have about 20 or so tabs open and go back and forth between these. I have googled and read allot on this topic and most people recommend starting in safe mode, without add-ons , creating clean profile etc and i have done these but slowly i get back into the same issue even after a clean profile.... It seems for every FF update the memory usage increases....back in the day FF was extremely fast and efficient. Or maybe latest FF just wants to remember so much and save just to much old information which leads to these ridiculous amount of memory usage, i tend to go over 3-4gig RAM after half a day alone before it crashes and all my tabs are lost which is extremely frustrating. Is there a way to limit the memory usage? Only helpful tips i have found so far that seems to remove allot of garbage from the cache and the footprint is going to about:memory and run the "minimize memory usage", this has been working great and so far after 2-3 hours its steady on 900meg (more or less) with 16 tabs open. Isnt this something FF needs to do regularly to get rid of old stuff ? i saw youtube and many other old stuff in the cache which i was not using and caused FF to go over 2 gig or so before i run this so why isnt this automated? as a user i shouldnt need to care about such thins really. I also used Safari for a few weeks with same amount of tabs and it never goes over 800-900 meg. I really hope you guys can explain and give me some tips as to how to limit the memory usage of FF and not the regular make a clean profile and generic tips. I really think the problem is FF and nothing else. I done extensive testing here and i'm using just a few add-ons Adblock plus All in one Gestures Swedish dictioanary Downloadhelper Screengrab Download Statusbar

Sorry if i sound irritated but having to lose my tabs daily and being forced to bookmark my tabs constantly just in case FF crashes has been bugging me for a while now and i'm on the verge to switch browser but frankly there is no other browser as good as FF (offering same amount of plugins/add-ons) so i badly want to use FF if possible.

If you need any more info let me know.

Cheers

After Firefox updated to 34.0, it suddenly started freezing up at inopportune times. Not always at the same point, nor at the same web site. I tried Google Chrome on the same sites Firefox would freeze and Chrome worked perfectly as did Internet Explorer 11. I also noted that it would only scroll part way then freeze, then scroll a bit more then freeze, so badly I could not view the page at http://www.dailymail.co.uk/news/article-2875544/How-escape-Alcatraz-Researchers-reveal-1962-escapees-presumed-dead-freedom.html. I tried this same page on Chrome and it worked perfectly. I did not have this problem prior to the latest update. Please also note that Firefox 34.0 may work fine for a day or so then start the freezing again. I tried Safe mode and could not get the freeze problem to duplicate. But like I said, sometimes it works fine then others not. I will try to remember to run Problem Step Recorder the next time it starts freezing. I also installed Troubleshooter as per below. I just tried the above page link and recorded it with Problem Step Recorder. It froze up loading but then started working again. Previously, it would show a Not Repsonding message in the top bar of Firefox. It did not this time.
