Diễn đàn hỗ trợ Firefox

hi about 2 days ago ff stopped working. i type an address into the usual window like i've done a million times, hit enter, and nothing happens. i click on a bookmark, the url shows up in the address window, but nothing happens. there are maybe 3 bookmarks that still work, and all the rest are duds. auto-complete still works, but firefox refuses to take to the address. i get a lot of "flash crashes" (thanks, adobe) so i recently updated flash, and that started the problem. this is why i distrust updates. (for the record, i keep current with firefox updates, even though it is still bloatware that uses 2 GB just to run 3 windows. anyway, any help you could offer would be most... helpful! (not sure why my exclamation points are printing as open-brackets, but hey, whatever, that's the internet) thanks, tim

Whenever I use Facebook dynamic search, Firefox stops responding. This issue also involves writing a new post/comment using the at-sign, which starts dynamic user search.

• Before update from FF27 to FF28 it did not happen. (I use Windows 7.)
• Safe mode does not help.
• Clearing cache and deleting Facebook cookies does not help. Neither new profile nor clean install helps.
• There are no crash reports within Firefox as well as no Windows error logs generated.
• Other browsers on this computer do not have this problem, another computer with FF28 that I use works well. Firefox 28 on this computer with Ubuntu Linux works.

Edit: I got Firefox not responding even at going through conversations (messages). So I can generalize that any operation at Facebook, during which three "waiting" bars appear, can lead to the not-responding state of Firefox.

After updating to Firefox 27 all webpages take a few dozen seconds to several minutes to load. When loading a webpage Firefox's status displays "connecting" and the CPU gets maxed out with 95 to 100% of its cycles taking by Firefox.

The computer is older so it is a little slow but Internet Explorer 8 has no trouble opening the webpages and neither do other computers on the LAN so it is not a network issue. I have tried restarting Firefox, disabling add-ons, deleting add-ons, disabling hardware acceleration, restarting the computer, and reinstalling Firefox after wiping every trace of it and its user data from the hard drive and registry.

Rather a long thread so I will add some comments here where easily seen.

• For general problems please see my post /questions/985969?page=3#answer-546520
  Updated 30th April 2014 to mention the outstanding known issue (aka the bug with only three votes)
• Just below that jigebren has kindly summarised some workarounds at that particular time and the issues found from this thread /questions/985969?page=3#answer-546599

• Workaround,
  A chrome hack to disable the throbber may resolve the issue as a workaround allowing pages to load quickly. See my post /questions/985969?page=4#answer-595327

i tried watching an episode of Friends on vodlocker & gorillavid & it starts to skip, the video become staticky, changes to green then crashes. (shockwave)

also Pandora does the same thing. i listen to a song, it starts to skip, shockwave crash box pops up. i stop the plugin then the tab closes.

i allow Adobe flash to run on the page.

i have no add ons or downloads. i reset firefox yesterday. i'm confused as to whats wrong.

OS : Windows 7 x64 I was using Firefox 48.0.2 (x64) - french version. I manually downloaded and installed Firefox 49.0 (x64). After installation, Firefox does not start : - the firefox.exe process is running, using something between 5000 and 65000 Mb of memory - nothing else happens : the process does nothing, using 0% CPU

I've seen this issue : - on several PC's of my organization - after automatic update or manual update - after having deleted my Firefox profile - after having disabled Kasperky Antivirus

I've noticed that the last version of Firefox Developer Edition has the same behaviour : install OK, won't start.

Going back to previous version is OK : Firefox starts again.

When we got up this morning my mum had a message on her computer telling her to download Mozila FireFox system tools 17.54.5468 - the message popped up when she tried to play a facebook game. We clicked it and downloaded it and the computer seemed fine after that (but we did notice something called uniblue was now on her computer). Then i got onto my computer and when i tried to get into yahoo groups i got the same message. I also got a different message when half way thru watching a video on youtube a screen came up saying that the certificates for youtube were invalid or didn't exist. I deleted firefox completely - including the folder in programs (x86) - reinstalled it and i can once again play youtube videos (so far) but i'm still getting a message for Mozila FireFox system tools 17.54.5468 when i try to get into yahoo groups. My question - is 'Mozila FireFox system tools 17.54.5468' a real message from you guys and if its not, does anyone know how i get rid of it? I have Windows 7 and its a desktop if anyone needs to know.

continous errors about "shockwave flash", "script has stopped working" etc, causing numerous slowdowns, lock-ups, and crashes. have tried several fixes, but none have worked.....please advise

As of this morning, I cannot get Firefox to work. I am using Windows 7. I click to start firefox and it looks like the program starts. It opens a Window with the minimize, maximize, and close buttons but the window contents are blank and the load icon appears. I can minimize and maximize the window but I cannot end the program. If I use CTRL-ALT-DEL, I can see that firefox.exe is running but I cannot end the task by selecting End Process. If I try to start another instance of Firefox, I get a warning box saying "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

Nothing I try will end the process.

I uninstalled and re-installed Firefox but the problem persists. I tried doing a fresh install with all previous add-ons and whatnot ignored but it still won't run. I've tried running it with the anti-virus disabled as well as with Windows in Safe Mode but it won't work.

Any ideas?

I just checked task manager, since my computer was running a bit slow, and found firefox to be using nearly 1.2 GIGABYTES of RAM, with only 4 tabs open + Chatzilla for IRC. I have Skyrim running at the same time, and it is using LESS RAM than Firefox is!

I've tried disabling plugins, to the point where I only have the Flash and Adobe PDF ones running, I had to disable the plugin container since it crashes repeatedly (Usually at least once every couple of days). I tried using the "Free Memory" options in about:memory, and they do literally nothing to reduce the RAM usage. It's normally between 400 and 600 MB (Which is still insanely excessive for a browser). Closing Chatzilla only reduces the RAM usage by about 10-15 MB, so it doesn't seem to be the problem.

How in the name of all that's sacred is a browser using more RAM than a modded version of Skyrim?

   /questions/982539 the addon no script was apparently causing 1GB of memory use.
   /questions/980440 a workaround was to tweak the pref Browser.sessionhistory.max_total_viewers to improve the memory issue

It crashes whenever I try to look at my Facebook updates (scrolling down), happened only recently when I updated to FireFox 38

Since two weeks or so, whenever I'm (also) running Firefox 53, all over sudden my whole pc freezes: nothing works anymore, no mouse, no task manager, nothing. FF does not create a crash report (doesn't get a chance to do so) All I can do is a hard reset. This does NOT happen when I'm not using FF. (Sometimes I get a warning that Firefox has stopped, but then it keeps running, so probably one of extensions or add-ons has failed.) I have a stand alone, always fully updates Windows 7 Pro SP1 x64 pc. SFC /scannow was ok, CHKDSK had to repair errors in the volume bitmap, and memtest86+/8 passes came clean. I cleaned up FF and am now only running one extension.

There can be three causes: 1. Firefox 53 2. Extension(s) 3. Windows (latest updates) 4. Other/unknown

I generated a memory report, which is abracadabra to me, but I it points out what's wrong and someone can explain what to do. But how can I post the memory-report.json.txt?

Hello all,

I am using the latest Firefox on a Windows 7 32 bit machine.

Unfortunately Firefox has been running very unstable for the last couple of weeks. Below I describe some of the problems:-

-Hanging momentarily ie. cannot click on links - Getting black patches on pages - Pages suddenly started to flash quickly

Things I have done to alleviate the problem

- Have refreshed and reset to default settings. - Have disable hardware acceleration in options - Have uninstalled graphics card driver (ATI), removed card completely and been running with embedded Intel graphics.

Unfortunately none of the above have solved the problem. Please also note I have a couple of addons installed but been running the same configuration on a 64 bit Windows 7 machine and everything works ok.

Willing to send crash reports, I would greatly appreciate it if someone could help.

Kind regards,

Kyprianos

firefox latest update has destroyed my laptop performance, have had to boot from windows recovery and no window fix repairs the damage. anyone any ideas what I can do to resolve the issues? I have tried system restore but that does not work either

Yesterday I had to reinstall Firefox as it did not exist......completely gone.....so I did a new install

Now the issue is and has been is I load Firefox and sometimes I cannot even access anything from the address bar it just sits there.

Its kinda hit and miss I can click on a tab and sometimes my favs are there and its all good. Seems like its doing its own thing..........no no we dont want that :)

What are your suggestions?

Thanks, Natalie

The Firefox plugin checker is reporting "vulnerable - Update Now" for my Java Deployment Toolkit 7.0.510.13. and Java(TM) Platform SE 7 U51 plugins.

The 'update now' link takes me to the Java download page which invites me to download the latest Plugin 7.51. but i already have 7.51 installed so the plugin checker is incorrectly displaying "vulnerable - Update Now". I have had 7.51 installed since January 17th and run the plugin checker on a weekly basis so i'm not sure why it has suddenly decided that this is a vulnerable plugin.

I am running Firefox 28.0 on Windows 7

thanks ...

Every time I go to Yahoo.com and try to sign into my mail accounts, I get the Recaptcha. It may ask me to click on all cars in the pictures. When I do that I notice the "Continue" button is superimposed on the pictures of the cars and then when I try to click on the "Continue" button, I get a circle with a diagonal slash mark through it. Yahoo won't help me with this until I pay money. This problem started when their pay for phone tech program started. Please help!

Sometimes Firefox actually stops working and "pop-up" window appears with the message "Firefox has stopped working". I have a process that continually monitors FF which is running a GM script 24/7 and when it spots that FF has stopped working it aborts the process and restarts FF. Unfortunately the pop-up window doesn't go away and the old process is still seen in the mix. If I manually click on the stop program button in the window then the new FF process also seems to die. If I close the window using the X button then I have a FF ghost process that won't stop. How can I stop the window from appearing?

Windows 7 FF 30.0 GM 2.0

Firefox repeatedly freezes after 30 minutes or so of use, and strangely when freezing it shows a blank page but with freeze frames recently opened YouTube videos and other flash objects, although it may not be all specific to flash. I can't remember exactly but there may have been some non-flash things showing too, but as far as I'm aware it was flash. It keeps doing this repeatedly and finally crashes. If I could give a number of how many times I've had to go through these repeated crashes, they have happened about 500-1000 times in the last 6-ish months. I can't go a day without them. They happen numerous times a day.

And here's the bit that stumps me. I've did the normal extension troubleshooting procedure, but even when every single plugin has been disabled at one point, it still crashes, so no extension can be the problem (also these crashes started about a year ago and the plugins and extensions hadn't been causing many problems before then). I also tested plugins, disabling any I didn't need and thought could be causing a problem, but it still crashed. I have even uninstalled and reinstalled flash, and updated it numerous times in the hope that the crashes would stop. But they haven't. I have EVEN switched from Firefox Beta (which I was in when it started) to Firefox (which still caused crashes) and now to Aurora, which, as you guessed it, STILL causes crashes. I can be on any page at all and it will crash. I have sent hundreds and hundreds of angered crash reports, no update or fix has been given that has helped the problem. I'm pretty desperate for answers at this point.

Below are all the crashes that have happened this month.

(If you find these on Mozilla crash stats, beware of strong language in the user comments. I was pretty angry when they happened.)

Please help, thanks.
