I'm trying to perform the clean reinstall for Firefox on my computer. But, I see the instructions for the uninstall, Delete the Firefox installation folder, which is located in one of these locations, by default:

   Windows: (Note: Check both folders.)
       C:\Program Files\Mozilla Firefox
       C:\Program Files (x86)\Mozilla Firefox 

Being I'm not computer wizard I had trouble finding the location of such folder. But when I accessed my program list in my windows program list I see a program named Mozilla maintenance service. When I click on that I see a format/window to "uninstall C:\Program Files (x86)\Mozilla Maintenance Service\." Is this the program/folder I need to uninstall to complete the proper instructions I need to perform a clean install? If so, when I delete it I then reinstall Firefox once again after the uninstall procedure? Is performing the uninstall procedure going to screw up my Firefox browser and my many bookmarks I have accumulated over the years? Can someone please help and explain? Thank you.

Hi, For about the last month or so, the Yahoo mail tab closes itself after I click on an email attachment to open the download dialog box. This happens exactly 30 seconds after clicking on the attachment, whether or not I go on to open or save the attachment. It does not happen if I merely 'preview' the image. I don't know if all attachment types behave the same, but it applies at least to jpg and pdf files. The tab can be reinstated via History/Recently closed tabs.

Firefox does not crash, and there are no crash reports. In other respects this is similar to a previous post by 'eladopoulos' on 4/30/22, 8:17 AM (https://support.mozilla.org/en-US/questions/1375635).

Using Safe mode makes no difference. I had set browser.download.improvements_to_download_panel to False, but reseting to True makes no difference. Thanks in advance.

I'm running Debian Stretch and the packaged version of Firefox (91) runs fine but seems a bit dated. I installed ver. 104 manually and everything is fine except that there is no audio. I changed the setup Privacy and Security Autoplay to 'Allow Audio and Video' -- no audio. I've restarted in troubleshoot mode -- no audio. Other browsers, including ver. 91 of Firefox have no trouble with audio. Any ideas? On quitting I get these messages:

I recently made the switch to Firefox. I attempted to use the version downloaded from the internet, which I already had installed for a long time, but it would not open. I then used the version available on the Microsoft Store, which worked fine. Eventually, Firefox crashed and would not reopen. A message saying something along the lines of "Are you sure you want to start Firefox in safe mode?" would appear for a split second, and then close. I tried:

-Starting Firefox in safe mode, but nothing happened. -Restarting my computer. -Reinstalling Firefox. -Running as administrator. -Checking it is not blocked by antivirus. -Using the profile manager to create a new profile: The .zip file version opens but does not help, and the version opened by using the "firefox.exe -P" command in Run suffers from the same problem as the browser and opens for only a split second. -Attempting to boot my computer in safe mode with networking, however, the Microsoft Store listed Firefox as uninstalled, and the network menu would not display any networks so I could not reinstall it. -Searching for any Comodo iseguard.dll files, but I found none.

The only thing that worked was searching "Mozilla" in files and deleting everything except what my computer said was part of the system. After that, I was able to open Firefox, but after a short amount of time, the problem started all over. I have no clue what to do and looking all over for solutions is driving me nuts! Please help!

When I open Firefox, I'm getting ** 12 ** instances of Firefox opening up and spamming the hell out of my hard drive (even slowing down other processes), even without opening a page (I have mine set to not open any pages on loading Firefox). This is annoying and intolerable. I have looked around to find a workaround, but the only post was from last year, and gives instructions to turn off recommended settings, then says to set Firefox instances to 1, where there is no way to do that in that section on the version I'm running. So, how do I fix this? I want the hard drive spamming stopped.

I Am on desktop:

i5 9600KF (high performance mode) 16GB 3200mhz ram NVME... Windows 10 Pro x64 Firefox last stable

When I open Firefox tabs aren't loaded all at the same time, but they are suspended. So after that: when I switch between 6 tabs quickly - they start to open at the same time. And CPU usage skyrockets to 100% LOL! Given I Am on high end PC - this is joke! I was using chrome and had hundreds of tabs and Chrome doesn't even suspend them by default. They open all at the same time I think!

So there is something wrong! I tried troubleshooting mode and it was the same problem!

Thanks for help!

First, this post is basically Congratulations for Firefox upon working almost flowlessly under this extreme heavy load without crashing. Saving/loading sessions works well. (which is unexpected but makes me _very_ happy :-)) Firefox exits properly without any exceptions, no matter how long it runs, or how many times the PC is sent to STR mode meanwhile.

Second, everything is fine, except RAM usage. No matter how many RAM is installed, Firefox takes up all of it after a few days of normal operation. I have recently upgraded my PC from 16 to 24 GB of RAM only for this sole reason to see if anything changes, but it did not produce any noticable change, except that it takes 5-7 days for Firefox to fill up all the RAM instead of the 3-4 days before. Disk space on C: drive was nullified by Firefox as the paging file went up to 50 GB.

I want to hunt down this thing. I have approx. 300 tabs, 2 addons, and Hardware Acceleration is disabled since otherwise Fox hangs several times a day (have to be killed from outside). Pics are attached. https://addons.mozilla.org/hu/firefox/addon/tree-tabs/ https://gitlab.com/kroppy/TreeTabs

I'd like to get suggestions where to start.

1. Disabling or replacing the adblocker ?
2. Inspecting memory usage on Process Manager (about:processes) and Task Manager (about:performance) pages ?
3. Installing some external tools like Firemin ?

Please don't suggest neither safe mode nor disabling all addons, since that makes it impossible to reproduce this amount of load, which is the primary reason behind the symptom.

I PrtScr'ed Process Manager and Task Manager, see that RAM sizes per page are normal in Task Manager, but not in Process Manager (10 times more).

CPU usage is totally normal for this load, even when memory is in the heaven. See the TaskMan pic. (I suppose that's because of ad blocking)

Thanks for any ideas,

Hello,

I've spent several hours today trying to fix FireFox slow start up on my system. After start up (about 2 full minutes), everything works normally. The hardware is an ASUS A88xm-A MB, A10-6800K processor, 16G DDR3, runs OS and programs off an SSD. I worked through all the slow startup suggestions, ran memtest (0 Errors, 1 Pass), disabled all add ons, (even the OpenH264 video codec (I use the onboard HDMI, no graphics card)), turned off hardware acceleration, etc. When starting in troubleshoot mode, less than 30 seconds, (acceptable), but I really don't know where to begin with the "More Troubleshooting Information" when I look at the table generated by it. There have been no other problems to date with the system, and the long start-up time began with 20.04 Ubuntu (about a minute), then got worse when I upgraded to 22.04 to try to solve THAT problem. Currently running FF 104.0, and the update page says wait for a distro update if that is how it was installed. I believe 104.0 is the latest Linux 64b version though. All updates to the system are done as soon as I'm notified of them. there have been none since the upgrade a few days ago.

Any suggestions? Gotta get some sleep now... TIA, Dave

Crash also happens when passed the argument `-safe-mode`. Does not happen in new profile. Crash happens both in v96.0.1 and after downgrading to v95.0.1. Console output mentions "Exiting due to channel error." I have not been able to find a way of increasing output verbosity.

Hi guys! Stripe.com crashes FF. The site only displays about halfway down its homepage, then crashes FF. I've cleared cookies, all history, removed and reloaded FF, turned off tracking protection for Stripe at the address bar, lowered tracking settings to standard in FF, turned off hardware acceleration, and contacted Stripe directly. But they can't help with browser specific issues accept to offer standard solutions, which I already tried. Also, Stripe works fine in Chrome.

I'm using 1password extension, and for plugins: OpenH264 Video Codec provided by Cisco Systems, Inc. and Widevine Content Decryption Module provided by Google Inc. I deactivated both those plugins but no use. Ideas? Thanks! Ken

The past week or two it has been acting haywire and crashing daily. I uninstalled, re-installed, re-started computer. Nothing helps. I have attached picture of error message. windows 10 firefox version 92

iMac macOS 11.5 Firefox 90.0.2

Firefox pretty much crashed every time I quit. Doesn't matter if I'm looking at a web page or close all windows before quitting.

Restarting in Trouble Shoot mode doesn't help either.

The cause seems to be synchronisation - if I sign out of my account and no longer synchronise, the problem goes away and I can quit without Firefox crashing.

Beginning 3 days ago, for no reason I know of, Firefox has become sluggish and active windows frequently report that they are "not responding": the cursor will spin, character entry is impossible, scrolling can't be invoked, and even clicks on other open tabs are ignored. (As an example, it has required more than 5 minutes to enter this text so far, even though I am now running in Safe Mode.)

Memory and system utilization usage is unchanged from earlier views under Task Manager (FF with many windows/tabs open may take on average 1524MB out of 32GB on the machine, and perhaps 5% of the cores, more or less).

I have opened no new or never-used-before tabs in this period, and have also closed a handful of them to see whether that produced any difference in these symptoms. (It did not.)

As mentioned I am operating in Safe Mode and these errors persist. In any case my only add-on is Adblock Plus. I upgraded FF to v87.0 last night on the chance that the version change would make a difference, with negative results.

At the moment Troubleshooting info indicates that I have "9/9" Multiprocess Windows, and I will try to include an image from that page.

These hangs occur in all windows, so the fundamental problem appears to be in a more basic process.

No other function on the pc is misbehaving in any way, but FF itself is now nearly unusable.

The only temporary cure I have found is to restart FF, after which there are no occurrences of non-responsive windows for a period of only 3 minutes to 15 minutes (during which FF memory and cpu utilization are generally constant).

Reinstalling FireFox or engaging in further profile updates or about:config changes are all well in scope for this problem determination. The one restriction here is that I cannot afford to lose my current windows/tab entries.

Many thanks in advance for all assistance, questions, and suggestions!

Hello Firefox Support Staff,

I use Firefox on a Windows 10 desktop PC.

Firefox often crashes when I close the browser by clicking the X either at the top right or the tab.

Please let me know the type of information you need to debug.

Thanks, Sam

firefox is my goto browser-tons of bookmarks etc-always kept UpToDate along with my dell MS10 laptop - today laptop boots up fine, outlook and MS edge work fine, but firefox will not start up, even in Administrator mode - searched for help - tried the run command firefox.exe -p, and also tried to create new profile ( as suggested ) that didnt work either- i would hate to uninstall and reinstall ! any help besides that ?

I am using the latest version of Firefox with Mojave on a Mac.

Lately I have experienced slowness despite the fact that I didn't add any software and I have Norton checking for viruses. Recently I got a message "Your system has run out of application memory" when I had 5 tabs open in Firefox. I checked Activity Monitor and it showed Firefox using 1.16 GB. 7 other apps were open, the next one with the highest memory usage was Mail (465 MB). Activity Monitor showed 30 instances of FirefoxCP Isolated Web Content entries.

I attached a screen capture showing what Firefox was using in one of these instances. Is this "normal" with 5 tabs open?

I closed the open tabs and quit Firefox. Memory usage by Firefox went down, but after a short time the problem happened again.

A search on the internet showed lots of similar complaints about FirefoxCP Isolated Web Content. Is this a known bug? Any way to avoid this problem?

Thanks.

FIX what seem to be CLEAR conflicts with relationship between platform and user's device (desktop, Dell Optiplex 790 in my case - that do NOT occur with Opera, otherwise) as WELL as aforementioned ATROCIOUS performance quality - BTW, this is the SECOND update / upgrade I've done in LESS than a WEEK.....

I cannot browser the following domains from just two days ago (2021/10/1). I received the error message I had typed on the topic "sec_error_expired_issuer_certificate".

https://www.liveinternet.ru https://warheroes.ru

I had checked somebody had the same error message several years ago and went to check the Certificate tab as mentioned in the following thread:

- Tools > Options > Advanced : Encryption: Certificates - View Certificates - Go to the Authorities tab. - Scroll down to the VeriSign section.

Now I don't know which Certificate are needed for "www.liveinternet.ru" and "warheroes.ru". Can any body help me to obtain the Certificate and found the old Certificate and delete it?

I am using firefox 12.0 but not willing to update it. Please understand I do not want to update my browser as a solution to solve the error messgae. I can't find any link to add exception when I visit these 2 domains (www.liveinternet.ru, warheroes.ru) ...

Can anybody help me as soon as possible. I visit www.liveinternet.ru everyday. Using another browser is annoying for me to browse liveinternet.ru...

The following image attached shown what problem I am facing...

This is the 3rd time I've posted here about crashing in the last month or so. I really do apologize for having to post again but I simply haven’t gotten to a solution. I really need to continue using Firefox as all the other browsers are significantly slower in my experience and I'm in the browser around-the-clock. I’d be willing to pay for customer support from Mozilla but they do not provide any type of support directly as most of you probably know.

Please review this link here to see all the steps I have already taken to troubleshoot the crashes.

I really thought that the crash reports I had would help me pinpoint the issue but it appears as though they’re not very helpful for those who can interpret them. If that’s not the case, I greatly appreciate it if anybody can dig through them to uncover some insights related to why I may be having frequent crashes (I'm willing to pay).

Thank you so much for any help.
