منتدى دعم ”Firefox“

Firefox has been my browser of choice for about 6 years. On 3/16 /15 it stopped working. I tried all of the suggestions. I then completely uninstalled Firefox and Mozilla Maintenance. I restarted and checked my disks and memory. All other browsers: IE, Safari, Chrome & Opera work fine. I installed from Firefox Setup 36.0.3.exe this morning. Same problem. Works for about 5 minutes and then hangs.

Firefox hangs. Doesn't give a clean crash. Doesn't give report. Cannot restart. Removed completely (even Mozilla Maintenance) and re-installed: same problem.

What can I do?

I get infinite loops in Firefox from certain webpages. I tried Safe-Mode, and couldn't even get to the main site causing an infinite loop in Firefox (Apple Bug Reporter), but could get there in Chrome or Safari. I used Activity Monitor to Get Info for Firefox, and then took a Sample. There were 375 instances of "mac_plugin_interposing_child_OnShowCursor", along with 107 instances of "DumpCompleteHeap". This problem is occurring on three separate Macs running the same or different versions of Firefox. One is 10.5.8 (Leopard) with FF 16.0.1. The other two are Mac 10.6.8 and Mac 10.10.5, each running FF 41.0.2 (latest FF). This infinite loop has also occurred in at a kp.org site where I was trying to view a doctor's profile. I have a 1647 line Sample.Firefox.txt that shows what happened in Safe-Mode attempting to get to Apple Bug Reporter. That file is 217Kb in size, and I'm willing to attach it to an email to Mozilla.

So, i tried several things in the troubleshooting articles here in the Support, but none solved my issues.

Basically, after Firefox automatically updated to 40.0.2, the browser hangs a lot on opening and closing tabs, as well loading websites. When not doing anything, the CPU/RAM usage is normal, but opening or closing tabs uses a lot of CPU (most of the time, 100% of the CPU is being used when browsing) and it hangs every time. Scrolling down pages also causes the browser to hang. I tried disabling several plugins and extensions and I even tried using safe mode, but even in safe mode it happens constantly. I'll post the specs of my computer (not big deal), but remember that these issues didn't happen before the update.

Please, did anyone find problems with this new update? What should I do? I've been using Firefox since 2007 and I love it, I'd hate to switch to another one.

Got one message saying something about the server connection being broken during the page loading. Then I force quite FF and tried again, and got a runaway script popup box -- but the buttons were non-functional so I could not stop the stupid script. Had to vorce quite again.

firefox is proving to be a real piece of shit software.

When I bring up a spreadsheet online in google docs Firefox starts dimming the screen, others tabs run slow. The screen dimming will last, for 2-3 minutes, and then clear up, 2-3 minutes later it will dim again. The fewer tabs I have helps, but not the answer. IMO the problem has gotten worse over the few upgrades. I have an HP 2000 Laptop, CPU 1300.000 MHz, memory 7586 MiB.

Thx, Larry

For about the last month I have seen my Firefox browser get very slow. I also see for a brief time, a message at the top that says "Firefox not responding" when I access a web site. This message at the top of my screen window only lasts for a short time, and then disappears. I would appreciate any help and suggestions that may help my problem. Thank you.

I had 3 tabs open. While browsing my computer slowed to a crawl. I have experienced this many times. Even disabled my two addons with the same result. What can I do?

See the screenshot.

I just upgraded my computer to a 1 tb hard drive and installed windows 10. Now firefox doesn't work right, example: I go on Facebook or another site and when I try to type a post I have to type 2 or 3 letters, then wait several seconds for them to appear. I have re-position my cursor and type 2 or 4 more letters and wait again. Can this be fixed?

After the recent update 81.0.1 (32-bit), I have started facing an issue where after every few minutes of browsing, all my tabs become unclickable and hitting enter on the address bar shows its loading but the website never loads. Trying to close firefox using the close button also doesnt work and I have to open task manager to kill the process and then start firefox again.

Today I tried to launch Firefox from the Norton Support menu, It took more than two minutes to load. After that it takes two minutes on restart. When it finally runs all websites a lightening fast, except for Norton, which is very slow if at all. Three sessions with norton chat support have not improved anything and following the Firefox troubleshoote including reinstallation have not solved either.

I have refreshed. Reset. re-installed.

So slow like a dial up.

Someone told me there is a 64bit version. Is that true? If so how do I get that and get all of my bookmarks . open tabs etc.

If I download a file, and click firefox's download manager the entire PC freezes for 30s or so. I'm using firefox 39.0.3, on the latest version of manjaro 64 bit xfce, and been having this issue for a while. and hoping for this issue to be fixed each time a new version comes out.

I don't want to reset my profile.

(Sorry for my bad english, it's not my native language) Hello, it's been many months that I have a problem with automatic scrolling Firefox Maintain pressure on the mouse wheel can slide in all directions of the web page, very useful for long pages and also for very high resolution pictures.

Off for several release (from 40.0.0 I think but not certainty), scrolling stops and / or is extremely slow and choppy until the page is not fully charged. This is all the more painful if we wait for loading a heavy image on a slow site.

I tested with the Firefox Safe Mode and it changes nothing. Disable graphics acceleration nor solves this defect. Test a new blank profile ... Remove and reinstall Firefox ... Namely I met no automatic scrolling problem on Internet Explorer or Chrome.

As I visit large high resolution photo galleries, is often sucks having to wait finish loading before dragging on the page with the pressed wheel. I leave then your knowledge to help me determine the source of this defect.

I have 3 PC's that have all been upgraded to W10, and all 3 have FF as their default browser (2 PC's home built the other is a Samsung Series 7). On all 3 of these PC's FF hangs for no reason, and even more baffling they all seem to hang at around the same time. Most often I will minimize FF and walk away from the PC only to come back later and not be able to access FF. When that happens the FF window is almost slightly blurry and the only buttons available in the window are minimize and close.

Yesterday I updated 2 of the PC's to FF 40.0.3 but FF still hung in less than 24 hours. The other PC is running FF 28. The only thing these 3 PC's have in common is that they've all been upgraded to W10 and they share some of the same add-ons. Any suggestions on troubleshooting this? I did try disabling Flash but that did not resolve the issue.

Hi I saw the article about getting firefox to use less resource but I have no extensions or addons and removed flash entirely really bare bones vanilla firefox version 43 - its killing me. Using up to 90% CPU and hits over 411K memory - nothing else really running closed everything I could in task manager except what won't close or needed to keep things running and a few web pages open - locks me up. Thanks

I'm running XP64 pro. The scripts on Yahoo will stall FF after a few minutes. Often I get the popup message that a plugin script has stalled and asks if I want to prevent seeing this again from the site. That's nice but every page on Yahoo is unique. So the stall happens on every page that isn't closed after a short while. The more stalls I get the slower my computer runs even though I use task manager to kill stalled processes. Then I have to reboot to clear out the FF remnants. Is there a way to kill remnants of stalled scripts without rebooting? Often FF crashes and asks me to send a report to Mozilla. Seems to me you guys should have a feature to enable extended logging for inclusion in crash reports. I have sent many requests to fix the problem. If you guys can't fix the root cause of the problem then can you at least provide a decent workaround so the memory doesn't get cluttered up with orphaned threads sucking up all my CPU power?

In the past weeks, suddenly my Firefox started behaving really weird - a few times a day the currently opened tab becomes unresponsive (you can't click or hover anything) but you can still scroll through them (at least a bit - after that point, it's just plain white). At these times, the cursor is the hand one, during the whole unresponsiveness episode, as if everything was clickable (though obviously clicking does nothing). You also can't close the tab during this tab - the only way is either to wait a good 30 seconds for it to unfreeze or to change to a different tab and close the unresponsive one. When you do change tabs, though, the newly opened tab sometimes disappears completely, with a radial loading circle appearing in the middle of the screen for a few seconds before it magically reappears (it does _not_ reload, though!). From what I've been able to observe, this tends to appear on content-heavy websites like Reddit, Facebook and YouTube most often.

What is happening? I haven't changed my browsing habits in the past weeks, nor have I installed any new add-ons. I've tried disabling the ones I have but it's still happening with them turned off. What else may I try?

Recently Firefox has become nearly unusable. Opening links are *_sluggish_*... They eventually complete but it's annoying - I've switched back to brave for now. https://support.mozilla.org/en-US/questions/1175357 seems to be the exact same issue however nothing in the thread resolved my problem.

I'd like to stay with Firefox but it's not worth it at this time. :(

Any thoughts/help are much appreciated.

Since I upgraded to v34.0.5, FF has been intermittently freezing and consuming all my CPU, making it a PITA to use. I never had this problem with previous versions. Anyone else getting this?
