Firefox Support Forum

Hi can somebody help me please? Sitting here on Christmas Eve at work trying to fix Firefox.

In a nutshell I have a really really annoying bug with Firefox which is going to cause me to pull all my hair out.

In the past the program used to check for updates and it used to work fine during this procedure.

Lately though I've been experiencing a really strange bug.

Whenever Firefox checks for updates the browser then cannot load a single webpage or anything while it is checking. Sometimes the checks can take around 3-5 minutes to complete.

Any videos or streams come to an eventual halt.

I have tried tweak a few settings in about:config such as app.update.interval

I have tried uninstalling and re-installing the browser - No change. This still happens usually about 5-8 times a day.

This computer is used for medical emergencies for our clients. We need a full functioning browser. I thought Firefox was that browser but I am beginning to think about installing something else now.

In these situations lives could be put at risk and I want to remedy this problem now before the new year. I imagine we will have a lot of patients coming in. I need to quickly submit forms at times and I really need a stable browser.

a) Can I turn off updates? I would prefer to check manually for updates once a week or so via Help -> About b) Can I reduce the frequency of the checks for updates? c) Is this going to be a normal feature for Firefox from now on?

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.....

Since a couple of weeks my Firefox browser for Windows 10 64bit has issues. Last update 90.0.2 did not work either,and the issues is still there.

Internet is extremly slow,some sites will not open and i cant logg in to Facebook.

Under settings,i have tried different settings. Right now i have the standard setting. Under Help,i have tried to restore,diagnos and clean catch and restart,but it has not solved the issue.

What could be causing these issues? Do i have to do some special settings or do i have to add some Add-ons/Extensions in order to have Firefox work normal again?

Hello,

since a week or so portal I frequently use - www.wp.pl started to work really slow. It crashes all the time, browser becomes inoperative, closes by itself, etc. It obviously happens to all pages, articles, services related to wp.pl. I cannot open a single page from wp.pl domain without issues. Before it was working completely fine, all of this started to occur for no reason. Also, it happens to wp.pl only. All other pages/portals/platforms function normally. I checked on different browsers - IE, Edge, Chrome and it works fine. I also cleared cache/cookies/browser history in Firefox and this didn't help at all. Therefore there must be something wrong with Firefox browser. Could you please investigate?

Thanks, Jacek

Hello Firefox Team,

I use Windows 10 - 20H2 version and Firefox latest version.

In the last time, i got error on firefox. firefox cannot display some websites. Firefox is experiencing a delay in responding.

For example myvideo: https://youtu.be/jILxKYqspew

Step 1: Visit : tmconsultancy.com or denetcilerymm.com.tr (any website) Firefox: waiting response Step 2: open edge and visit tmsconsultancy.com (fast response) . I have been experiencing this error for the past 1 year. I completely force uninstalled Firefox and clean installed.The problem was not fixed.

However, i do not use any plug-ins or virus programs(on firefox). This problem is very annoying.

Can you help me please?

Regards

System OS: W10Pro_x64 21H1, Defender, no Firewall, no extra AV. Firefox_93.0_x64

Addons: Adblock + µblock FBPurity Block Sender New Tab Override Cookie Manager and Cookie quick Manager Auto-High-Quality for youtube Ant Downloader Video Downloadhelper Cute Save Button WebP Image Converter Translate Web Page

Additional Information: Open Pinned Tabs: In between 25 and 60, depending on my current activities.

Tried: Disabling each add-on until all were off. Safe Start. Nothing helps.

Understandings: 1) No browser is made to run up to 60 open tabs (possibly even more)!!! 2) I run a "plethora" (compared to most users) if add-ons; these also bring the use speed down. 3) Resource used: 2GB (with "mere 30 pages" open.

BUT: DESPITE that: I ALSO understand that, considering my system and Network Type, it should not even be problematic with 200 pages open at once. 2GB over 32GB of RAM? Not the slightest issue (and it often runs at 4GB RAM in use). My CPU never runs half high, even when I have like 60 pages open: Should not be an issue then either. My Video Card has plenty resource over as well when at highest for me usage." Again, it should be no issue. My Fiber Netware? Telenet BVBA, Mechelen Test results: Ping: 5ms Jitter: 2ms Download: 904.2 Mbps Upload: 038.3 Mbps Not the best, not the worst, but for simple browsing, more than, I would assume, plenty.

So, what gives, what is the issue? No extreme strain on the system, no background high-resource issues, sure: one or two add-ons in Firefox but these as well do not strain my system, no AV issues, no Firewall issues (I turned that off, I fail to get the need for one as a house-dog-tree user), yet slow performance. Also, while 30'ish tabs running, 2GB used of RAM? My my, what the hell do they do as Site Admins to have these amounts (and NO, I do not do porn, thank you.  :P I am well aware of other people having insane issues surfing porn, as I helped many of these folks)? Sure, Deviant is a larger one that is open, being a graphical site, but like Quora, FB, Hot- and G-Mail and similar, these ain't, so to get a 2GB usage is weird, I would assume. I said, assume: yes, I am not specifically an internet know-all, I know of networking as a former NOVEL Netware Supervisor under UNIX (also Spupervisor), but Networking in a company is not the same as internet.

So, what is going on, why is my browser so slow? Having turned of all and 1 page open it's lightning fast, but now ... So, it is the open tabs, and the add-ons, though when turned off, I see no real difference. Brings it to tabs. How come, it is this "heavy", even for my system, please?

Thank you. Xog.

Hi, hoping someone can help point me in the right direction....I have a web app that has lots of data, we run several scripts that can take a while to process. All was operating fine on version FF87, version 88 would just stop processing the script and the browser would not allow me to do anything else on that site. ... there were no error messages (that I can find).

I downloaded the Beta of V89 and all worked fine Public release of V89 has the error It works fine on all other browsers It works fine on the local server version on my machine

site is php7.2 ...

...any information would be helpful to me.. please and thank you in advance!!

I am getting more & more frustrated and exasperated, as simple browsing has become tortuously slow, with many sites taking forever to load, or only partially load, or have to be refreshed a couple times, to finally get it to load. And videos constantly freezing up, despite lots of free RAM, and a very high-speed internet connection. I assumed whatever was causing this would've been addressed in the last update, or two, but no, it's only getting worse.

After this last update Firefox is really slow loading pages and has crashed on me multiple times, I have also noticed if the browser is up it slows other programs down now like when im burning a cd. Is anyone else experiencing this? Thank you

Since the last Firefox update (92.0.1 64-bit), my bookmarks menu is slow to load, and also slow for navigating. It's slow to load the list when I open Bookmarks tab. And it's slow when I move my cursor up/down the bookmarks, it takes a bit for the highlighted bookmarks to catch up. It's very odd. I don't really have a lot of Bookmarks, I would guess ~500 total. Plus I am using plenty of RAM with Windows 7 on a SSD.

Bookmarks loading and accessing was lightning-fast prior to this last Firefox update. I have searched on this Forum for answers, plus Google.... no luck yet. I'm sure there is an answer. Does anyone have it?? Thanks for any help. Dave F.

PS - I LOVE Firefox. Many thanks to Mozilla for a terrific product! ;-)

It doesn't crash every time, but when it does, if I restart and try to save image/video/etc. again, it will usually keep crashing a string of times before it finally allows me to download without going "Not Responding" and at which point I have to force quit.

I've tried browsing other solutions but nothing seems to work or be applicable. I'm running Firefox 78.15.0esr (64-bit) on an El Capitan 2010 iMac.

Thanks for your help!

For 3 days now, I have not been able to view or use anything in my Facebook account. The page would drop the internet because it was too slow. I have tried various things from support and also received 1 from the community. it has not worked so I am going to switch to Microsoft Edge because I did not experience this problem with ME. I have used Firefox for years but the slowness is very annoying. I will try it again in the future. Thank you

Every now and then my firefox does not respond when I click on any links on any webpage. It only works when I clear the browsing histories and cookies for last hour. This happens like every 15-30 minutes and is very annoying that I have to keep clear off the history.

A few weeks ago I noticed that browsing in Firefox started being slower / sluggish.

It usually happens in YouTube or Twitch, but can also happen while scrolling with the mouse in wikipedia for example.

Some examples: -When having a Twitch stream open, the stream is running fine, but when clicking and moving the volume slider on the player, it does not move smoothly, and with some delay. -When doing a bit more heavy browsing, sometimes a tab might get "stuck", for example, the twitch stream might start to buffer for a few seconds. I notice the buffering is not related to any bandwidth related issue. -Firefox reacts slower (or with a small delay) while moving between tabs, clicking on links, etc. This usually happens only after a few hours after launching and browsing with Firefox.

Most happen after a while since I launch Firefox. And by a while I mean maybe 2-3 hours, and I don't have a ton of tabs open. It becomes slower much, much faster than it used to in the past.

Now, sometimes it can take Firefox up to 30 seconds to close completely, before I can launch it again.

I had the same Extensions installed before these issues started happening.

I tried uninstalling Firefox completely, then manually deleting the remaining profile folder, and do a fresh install of the latest Firefox version.

I checked the Windows Task Manager, and it shows (14) processes under Firefox. Is this normal? I tried unticking the "Use recommended performance settings" and restarting Firefox, but it still reached (14) processes after a couple of minutes.

I am not sure if it is related to Firefox itself. My computer is 5 years old but functioning properly...

I did not check if similar issues happen on a different browser. I am just so used to Firefox.

I had a few weird bug in Windows 10, but those existed for a good while now, and are not similar to the ones I experience while browsing with Firefox. I didn't notice anything similar while watching video files in a Media Player.

I am not sure if it can be hardware related. All seem to be working properly...

I want to figure out what is causing this. If you need any more information let me know.

Hi, for the past week whenever I open Firefox (FF) it works normally for about two minutes, then slows, then causes my entire mac to slow and freeze. If I don't force quit FF quickly, my mac crashes. Once I force quit FF everything is fine. I've been using Chrome for the past week or so hoping FF would fix itself with an update but no go.

Anyone else having this issues?

Just today, firefox began slowing down and soft crashing for minutes at a time. During this time, I can interact with websites, but it doesn't change the visuals or show that anything has changed. new tabs open but don't show up, youtube video audio plays but the screen remains fixed. Firefox usage for just 7 tabs is well over 5 gigatybes of ram and 10-20% cpu at all times.

I attempted everything on the help page, including: killing and restarting firefox, updating firefox, updating windows, restarting my computer, killing firefox and rebooting again, disabling extensions, and updating graphics drivers.

after rebooting with the new windows update, firefox ran smoothly for a brief minute and showed normal cpu/ram usage, but quickly climbed back up to pre reboot numbers.

Searched the forums and web, no one seems to have answer that I have found. Firefox 95.02, Windows 10 Pro, 8 GB RAM, Dell Notebook, fiber optic Internet 156 mbps Start by running CCleaner, disable un-needed startups, extensions, ad-ons, ect., then roboot, have clean slate. About 3 months ago, after about 15 minutes Firefox slows down, then quits loading images, then eventually quits loading whole pages. If I was blocking content it would not work for at least 10 minutes. This evening, 21.38 clean boot, start FF, go to Facebook, read notifications, 1 tab open, nothing else running 21.55 images fail to load, still one tab open Researched more and ran about:memory, memory-report.json.gz unable to figure out how to upload Run CCLeaner, I do not save cookies or cache after FF closes, reboot 22.04 start Firefox, 1 tab open nothing else 22.16 images slow loading 22.20 nothing loads, try other websites like NOAA radar, all fine Reminds me I saw at the bottom left "Waiting for static.xx.fbcdn.net" Screen shot of Task Manager attached, FF running 10 times, 154 kb image will not upload Failed to upload, copying this txt and starting over. Images loaded fine after reboot Facebook works fine on Edge, I do not have/use Chrome or Google Facebook is the only page Firefox has issues with.

Hellow,

Since updating the latest firefox version 91.01 it has considerably slowed down browsing speed to an impossible crawl. The task manager shows the update as permanently on, sucking 100% resources. There´s something not right when it does this, and is becoming a bad habit of constantly refreshing firefox to get sensible operation.

It started by installing a clear cache which helped as firefox also hangs when connecting to the internet as a result it goes off-line at random times. Barely ideal. 

Is it worth rolling back to an earlier version that is more stable ? Any other users got debugging suggestions ?
