Diễn đàn hỗ trợ Firefox

okay so after I updated firefox with my windows 10 update, everything was fine. but lately I have had issues with certain websites not loading. so after I refreshed firefox to its default settings, uninstalled and re-installed nothing works properly in firefox. ever since I did the refresh its making me mad that nothing is loading. I attached a photo of what my web pages look like. I tried to go to help but everything is messed up on the pages. can anyone help me with this??

Firefox will not start. It claims to be already running, but that doesn't seem to be the case.

I have tried creating a new user profile but when I try to open Firefox now, the "choose user profile" menu pops up. I have tried the new profile and they old one, and both give the same error message. "Firefox cannot use the profile "Default User" because it is in use. To continue, close the running instance of Firefox or choose a different profile."

There is an entry for firefox.exe in the "details" menu of my task manager, and nowhere else. When I try to end that task, I get the following error: "the operation could not be completed - Access is denied."

Due to some troubleshooting research, I've tried deleting the parent.lock file from my profile folder, but I get this error- "the action can't be completed because the file is open in Firefox."

I tried transferring my bookmarks and preferences from Firefox to Chrome, but I got a similar error suggesting that Firefox was already open and I would have to close it first.

I have also turned off my computer and uninstalled and reinstalled Firefox multiple times.

I'd really rather not lose all of my Firefox bookmarks, add-ons, and preferences. I also prefer using Firefox to Chrome, so if anyone can help me out I'd really appreciate it. I don't know what else to try.

My PC runs Windows 10, by the way.

my firefox browser does not load properly. i have updated browser and followed trouble shooting steps to reinstall again . The trouble first started with Yahoo not loadiing and not showing images and email not loading properly. When i try to open addon pages or any other pages in firefox help they do not load properly .Also i cannot install any add ons for example print edit. I have checked that javascript is enabled and it shows it is enabled as true. I have included screen shots of this problem.

I'm having problems loading Youtube in Firefox, both the subscription page and any individual video will freeze for a few seconds whilst everything is loaded in and I won't be able to scroll or change tab, CPU core max out, fan sometimes comes on. There's basically no delay browsing it in Chrome.

Attached a "Performance snapshot" of the page loading and it seems to stick in 3 places performing "Graphics/paint". These phases seem negligible browsing a page with equivalent number of images (eg. BBC news site).

So I'm wondering if it's due to the website just having an overly complex layout, is a known problem, or if there is something I can do to reduce the load?

Thanks, (Installed Win 10 from scratch last week, all updated, and no extensions to speak of. i5-3230m, gt-650m 2gb/intel HD, SSD)

When I open Firefox,it works fine but after a while,sometimes less,sometimes after few hours or so,it gets stuck with "connecting.."and it won't open a webspage. To make it work again,i have to restart the pc or just wait for 30 mins or sometimes more! Edge browser works absolutely fine.It doesn't give me any error message at all! as In the image you can see,it's been at least 30 minutes that nothing is happening!

Windows 10 and Firefox were running well on my (old) windows 10 Compaq pc. After uninstalling eset nod32 and installing Sophos it ceases to really start up. In task manager I see Firefox somewhere down below, but it does not complete the startup so I do not see the browser opening. Killing the Firefox instance, reinstalling and restarting it without any add-ons (they were https everywhere, bluehell firewall, CSfire, Click&clean , Privacy Badger) does not do the trick  :-(

Can you help (other than unistalling sophos...) ?

Cheers, Wim

Today something wear happened, I was in Facebook when firefox freeze then y close it and open again, but when it open everything was pixeled or deformed! I already uninstall it 2 times but nothing change. =(

I've upgraded my 64-bit Windows 7 Pro installation to Windows 10, taking the opportunity (at the same time) to install an SSD and re-installing everything from scratch. I have tried (several times) to re-install Firefox, and whilst it appears to install OK, if I click on the Firefox icon to start it I get an error message: "Windows cannot access the specified device, path or file C:\Program Files (x86)\Mozilla Firefox\firefox.exe. You may not have permission to access this file."

I have tried running it with the Windows 10 Firewall both turned off and on - but this didn't make any difference. (My primary Firewall is Kaspersky Total Security.) Edge, Internet Explorer & Opera browsers work OK, but Google Chrome doesn't work either. Is there a clue to the problem here? I hope someone can solve it for me as I prefer to use Firefox over Opera. Thanks for your responses.

Latest version of Firefox , always keep up to date .Windows 8.1 running on del optiplex 620 , 2gb ram , 80 gb disk partitioned with Win10 on the other .Running free Panda av and malwarebytes free . Never had any problems with Win 8.1 until now , I have gone back to it because of the many problems with Win 10 . Have checked event viewer , nothing , have checked for crash report , nothing . No malware reported . Every time the only solution is to stop Fox with task manager and then restart when Fox goes back to where it was .

I had Waterfox on my computer up until a few days ago. I got a bug. I uninstalled a few programs to reload. When I download waterfox and firefox, I get these messages: Your profile cannot be loaded. It may be missing or corrupted. I cannot find the profile manager in the files. I tried using "run". I have uninstalled it and did a clean boot and installed again: no good. I have windows 10 on an HP Notebook. I have tried most of the fixes I found for this problem but most of them are old fixes. I will appreciate any help you can give because I have found Waterfox is the best browser for me. My computer is a 64bit. Thank you, Marcy

HI, I've been having this problem with Firefox for the last two days. It does not display context and formatting of websites like Reddit, Mozilla, and sometimes YouTube. It has said many times that websites like youtube have an untrusted connection, and shockwave flash crashes. I tried uninstalling , cleaning, and reinstalling Firefox, I tried repairing it also.. I updated java, Flash, and shockwave. Did a complete scan of my computer with my Antivirus and Malwarebytes.

None of these problems are on Chrome or Edge.

Firefox had slowed to a crawl...took advice on support page to delete and rename the "places.sqlite" file in the file manager under Firefox. Now Firefox only crashes all of the time. guess my decision to go back to explorer has been made for me...can't fix the newest versions of FIrefox hangs up, slow, error messages...now only crashes and the "places.sqlite..old" file I saved is now gone, so cannot even go back to it...

Firefox no longer works at all..?

Since version 42 it's not showing any website properly. Not even in Safe Mode and even after resetting everything countless times. Even after uninstalling and re-installing it's same. Uninstalled and re-installed version 43; with default settings and all issues are still there.

As you can see in images, there are no problem with internet connection. Everything else is working just fine.

I have cleared caches, uninstalled, reinstalled, searched for any adjustment I could think of that would allow the flash to play. Flash players have been reinstalled, java reinstalled. reboooted, rebooted,rebooted. Have turned off all security and it still will not load. Some games even indicate what version of flash is installed but all I get is a plain white screen where the game should be shown. Videos will not load

Yesterday it opened normally, today it won't, as said above.

I tried renaming the Mozilla Firefox to OldFirefox, and clean install, still won't work.

When trying to open in safe mode, window open but then says : Not responding, and it jam like this.

I even tried to report my 5 latest bp- and it still wasn't conclusive.

Any answer somebody?

BTW my computer is a MacBook Pro with Windows 7 32 bits Legit Boot Camp, si maybe it does make a difference.

My Internet Explorer work, thought.

Thanks!!

Tried safemode, retune firefox, turn off LastPass.Diable plugins but,FF crashes most every time close, since updating to windows 10. Please advise. Trouble shooting data says I have windows xp as operating system...That is incorrect....This laptop I bought new from Dell with windows7

Thanks

Yesterday or the day before, I tried going onto YouTube using Firefox, as I usually do, and this happened (see attached image). I tried clearing the cache and cookies, and restarted my whole computer, and nothing changed. Firefox loads all other websites I frequently use just fine, and Chrome works just fine with YouTube, but for some reason, Firefox and YT are not mixing right now. Anyone have any suggestions?

The "firefox setup" page with the green bar is taking way too long INFINITE -- Not only does this not work on this new this laptop I bought yesterday, but it also wont download on my other laptop - 2 years old (same exact situation). So I can say there is something seriously wrong with your link or software.

This computer is running on all new hardware and software. Also, it doesn't work on my other laptop. Furthermore, this never happened with any other program or computer or browser ever in the past.

I am downloading Firefox for a masters program in analytics.
