Firefox Support Forum

Can someone help me fix recent frequent crashes ? This is just yesterday. I tried troubleshooting mode and it didn't happen there, although I didnt give it a long trial. I deleted all extensions, and I reset Firefox. Any ideas?

My Firefox bookmark menus are often taller than my screen.

When I select a bookmark well down in the current menu by typing a letter, for example "T", the menu display scrolls down to the first matching choice, but that choice can be mostly covered by the down-caret indicating more choices further down. I can see the top of the highlight for the current choice, but I can't read the text of the choice.

Not a big deal, but I'm hoping it's an easy fix. Thank you!

For the past two weeks, I've noticed that embedded maps make my browser immediately crash. I initially thought it was a Firefox problem, but I have been having a similar issue with Safari. This does NOT happen on my iPhone using the same two browsers. This also does not seem to effect Google Maps or embedded Google Maps, but embedded maps from other services. Anyway, I'm posting here because Firefox conveniently provides crash data, I'm not sure what else the cause could be and I'm hoping someone can help.

Two websites this has been consistently happening with are The Empire State Trail bike path (https://empiretrail.ny.gov/) and a NYC vaccine finder website (https://vaccinefinder.nyc.gov/). Firefox immediately crashes, though with the EST website it seems to be tied to the pathway of the trail being drawn (crashing after I've zoomed in a few times and the path has to regenerate). Safari doesn't totally crash, but forces a site reload and after it fails a second time says it can't display the site.

Any ideas what the issue could be? I'm on the latest version of Catalina (10.15.7), Firefox and Safari and seem to have all security updates for all.

Here's a link to the latest crash data: https://crash-stats.mozilla.org/report/index/1389c870-51cf-4790-b0a0-fd01f0211202

Hello. Im new to the Mozilla Support community

I am running a Japanese Windows XP SP3 on VMWare Workstation 16, i have downloaded a old version of firefox, due to newer versions not working on xp

And heres the issue: Firefox keeps opening tabs randomly which are related to pornographic websites like xxnx, pornhub, evilangel n' etc..

Heres things ive tried, but didnt work: -Install tdsskiller & scan -Scan with Avast Antivirus -Uninstalling Firefox and delete registry entries -Getting IE8 or G**gle Chr*me for Windows XP SP3

Any way to resolve this problem? i can't watch these things!

Recently I upgraded my Windows 10 to Windows 11 and since doing so, I've had consistent errors while browsing the web on Firefox. Most notably the "Humm. We're having trouble finding that site." error message.

For example, when visiting, say Verizon.com, the tab will display the aforementioned error to which I press Try Again and the website loads correctly every-time. No hiccups on the refresh.

I've tried the following:

1. I've performed a completely clean uninstall of Firefox and then reinstall
2. Cleared all browser history/cache
3. Removed all extensions
4. Disabled IPv6, HTTPS Over DNS, No Proxy
5. Ran through Firefox's troubleshooting
6. Used Firefox Troubleshooting Mode in the Browser
7. Tested that the problem does not happen while using Edge

I've never had a single problem on Windows 10 with Firefox. Curious if others are experiencing the same issues and if there are any fixes. Nothing else on the PC has changed.

• Windows 11 21H2 2200.348
• Network driver is the latest Win11 edition
• Firefox 95

Hope someone can help.

When I use full screen for some websites, it darkens after about 2 - 5 seconds and my cursor also becomes harder to move. This only started to happen recently.

It is not my computer settings, I've tested this in Safari and it works normally. This makes videos unwatchable. It is like a dark screen suddenly appears over the video and only comes off if i move the cursor. It happens with netflix and prime but not youtube, udemy.

Hi, The program SEEMS to start but Firefox does not load one singel page. I get no errormessage but firefox does not even try to open pages.

Also, if I try to go into "settings" nothing happens (no errormessage, but settings does not open).

I have tried to uninstall and reinstall Firefox. Does not help.

If I try some other bowser everything works fine. The problem started after I did a total uninstallation of Office365 (does not need to be depending on it but it could be a connection).

Have searched the web without finding a solution and now I ask for help here, I really do want to keep using Firefox but currently it is impossible.

For real — it's terrifying how much we don’t know about Facebook. The social media giant has almost 3 billion users (and tracks many more), but this year we've seen yet again how the secretive way it operates is dangerous for all of us.

By keeping us in the dark about how it combats misinformation, who's paying for ads and how social media affects our mental health, Facebook actively stops us seeing when it’s causing harm.

But here’s the thing: we're not going to just accept it.

It's true — Facebook's secrecy puts us all at risk. To keep us safe, we urgently need it to be open and accountable. Chip in now to join the fight, it takes 1 minute:

• button* Yes, I’ll chip in now

Firefox v90 on a Mac. Continual nag screen popping up telling of an update. None of the solutions presented by top contributors or moderators work. Nothing obvious or suggested in about:config. Nothing about putting policies in .json files in the correct directory.

It is as if Mozilla refuses to let you turn off that nag screen.

why is FireFox 95 opening multiple windows on startup with Windows 10, Roboform, & Norton 360? FireFox is set to open a new tab, not new windows, so I do not know why it is doing this? I see lots of people asking this question, but there is no guidance online. What is up? This is causing FireFox to use way too much resources, and slows the computer.

I have searched for this problem, and only come across outdated information about Youtube's intentional changes to slowdown Edge and Firefox in 2019. This is not that.

When I load a new youtube video, the video will buffer as normal, and then buffering stops. Then there is a delay of about 10 seconds. You can see from my screenshot that the buffer is filled just fine, and playback begins about 10 seconds later. This also happens if I skip ahead/back or to any position in the video. This firefox install is on a new install of Windows 11, with a new xps 13. The previous xps 13 with windows 11 didn't have this problem, and I don't have this problem on my desktop setup with windows 10.

I use a few addons: decentraleyes, ublock, duckduckgo and I have privacy protections set to strict. I have tried a few troubleshooting steps and the problem persists. Things I have tried:

• safe-mode
• fresh install
• installed additional codecs
• used user-agent workarounds to show as a chromium based browser
• turned off hardware acceleration

The problem doesn't happen on chrome, but it does happen on Edge, which is strange. Because of this, I'm wondering if there is something going on with codecs. In the firefox screenshot posted, the codec used is vp09, same with Edge. But in Chrome the codec is av01.

Firefox will start once (maybe) and then it makes no difference where I click from (tray, programs, desktop shortcut) Firefox refuses to boot up. I've tried re-installing multiple times. If I reboot, it will start. Also sometimes I will get a New tab but the page/URL never comes up. Firefox just hangs. I'm running Windows 11.

I have been unable to figure out how I've managed to make my addons no work properly.

I've tried running them in debug mode, but I'm not particularly adept in debugging addons.

I've reset Firefox back to default a few times, addons seem okay, and then as soon as my Firefox account syncs and installs my installed addons they go back to wonky.

I can't seem to attach images RN, Firefox (Nightly) crashes every time I click on the button.

The behavior can be described as the addons when clicked have a blank page as their contents, and some addons (Like Dark Reader) just have like a sliver of a drop down with no contents.

If you'd like me to grab some debug data from wherever just let me know.

google.com and google related websites doesn't load at all. For example, gmail slowly loads, but loading icon never disappears, loading icon is always shown and then often it shows 'reconnecting' message. This works OK in Chrome.

Steps to reproduce: 1. Open Firefox without VPN - all loads well. 2. Enable VPN - stops loading. If I then disable VPN - it starts loading again.

If I restart Firefox it starts working OK, but after a while stops working again.

(SECOND occurrence of this problem; not sure HOW previous instance resolved - my short-term memory ISN'T the best at present!)

Have taken all recommended steps short of completely refreshing (renamed a file titled 'config.json.old' as it was the ONLY one with a 'json' filepath suffix) because I don't want to have to relocate (another) existing session / configured profile by trial & error if avoidable - 'cookies' were removed along with history / cache cleared; reset / deleted related browser registry entries as directed, activated ' Troubleshooting / Safe Mode' contingency and STILL can't download anything (additionally, tried to do so with and without limited-time Malwarebytes web protections).....want to CONTINUE using Version 95 because by ALL indications and from what I'm seeing in Comments, my instincts about newer ones - were sound, WELL-informed.....please advise ASAP? Thanks!

Hi, Happy New Year!

Finally I took a deep breath and hoping for no major surprises and bugs, I finally updated Firefox to the latest version.

I have a few questions:

1. As advised, every month I backed up info in the profile, following https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles Is there an up-to-date version of these instructions as the prior ones no longer work (menus were changed, Troubleshooting works differently, etc.).

2. Does the "Allow for session" option for cookies work and if so, what does it do?

3. Is there a way to change the way the TABs look now (washed out, white, very hard to see and differentiate, hard to see which one is the one I am looking at). I am wondering what is the perceived benefit of this change. In the old version I had, the tabs very clearly delineated and easy to see.

4. Where can I find a listing of the enhancements and major changes of the versions released since mid year 2021, from an end user perspective?

Thanks.

I moved my Firefox installation to a new machine. After creating a new profile and moving all my old files Firefox has opened with all of my old info and is operating properly.

But when I tried to change the location of the cache file to the correct drive on my new machine the about:config file does not save the new entry. When Firefox is closed and re-opened the new entry has been reset to the old location.

I've tried deleting the browser.cache.disk.parent_directory entry in about:config but when the program is re-opened the entry returns with the old directory shown.

Any advise would be appreciated.

Firefox tabs crash repeatedly for a particular email website that I am using. Specifically, the tab crashes when I click on an link to open an email and see the email contents. The tab will not crash every single time, just occasionally (i.e. sometimes I am able to read an email without the tab crashing, other times not). I do not think that the timing of the crashing has anything to do with the email contents (e.g. length, format). I also do not think that the tab crashing issue is happening for any other websites. The crashing started recently, sometime late December.

I installed the latest version of Firefox, and I cleared the web cache, but nothing has changed.

Any suggestions?
