Firefox Support Forum

Machine is Windows 10 with a Logitech wireless keyboard. Latest Firefox browser. Not always but sometimes when using Firefox browser to log in somewhere or enter data on some web site, I'll get an incorrect entry for a key stroke. e.g. I enter a 0 and get a 1. But if I enter a 1 I get a 1. So far the error key has always been different.

I've tested things by launching a notepad or Word document and entering the character and in those all works fine. But go back to Firefox and I get the error again. What I have to do is to close and re-launch Firefox and so far this fixes things. It's an intermittent problem which forces me to keep another browser on the machine and ready. Imagine entering a password when all of a sudden you type 'X' and it gives you an 'E'. Really frustrating!

I have a PC operating on Win 11. just recently upgraded to the latest version of Firefox and can't find my bookmarks. not finding the help areas very helpful. how do I get them back and installed on left side of screen as I did in old version?

When I run a virus or add remover like Malware-bytes it considers the application a "PUP: Legacy" item and counts it as an item to be quarantined or removed. The count of items like this are adding numerous hits that keep growing. How can i stop this from happening?

Followed instructions on https://support.mozilla.org/en-US/questions/new/desktop/form and https://support.mozilla.org/en-US/kb/how-disable-enterprise-roots-preference "security.certerrors.mitm.auto_enable_enterprise_roots" is set to disabled but "security.enterprise_roots.enabled" is set to true but is greyed out and I do not have a toggle option to disable it - why and what is the solution ? No Anitvirus software except windows 11 defender is installed.

No "ImportEnterpriseRoots" entry available in registry and no HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\.... entry

Please help!

Firefox has been my default browser for longer than I can remember. Over the years, I have maintained a significant bookmark file for work. I recently purchased a new computer, and my zero bookmarks from the new computer have replaced all of the bookmarks that I had in my old browser. This is a bookmark file that has successfully followed me through multiple computers and even my ios devices. And now it seems to be completely gone. I've looked at the places.sqlite files, and the largest one is 20MB and is in my current default profile, but it is dated today. That makes no sense because I do not have any bookmarks on this older computer, and my new computer doesn't have any either. The bookmarks have also been completely deleted from my iPad, but miraculously are still on my iPhone (evidently I had signed out of Firefox for iPhone at some point so they do exist somewhere.) The thought of trying to rebuild my bookmarks is nauseating. My only thought is to sign out of the browser on all devices, then sign back in and sync on the phone. Would that repopulate the main file with what's on my phone? Any other ideas?

Hello fellow Firefox users, I sadly cannot use my Firefox (120.0.1, 64 bits, Windows 10) anymore as it is too slow to show a webpage... It's so slow, that I initially thought that I have no internet connexion at all on Firefox.

Can anyone help me figuring why my Firefox profile is so slow ?

Long story short:

- Until 2023-12-05, my Firefox was working normally.

 My parameters were "No HTTPS everywhere" and "No DNS over HTTPS (DoH)".

- On 2023-12-05, I was connected to an entreprise DNS (Mangling DNS).

 I cannot acces some website because of their local policy, so I changed my DNS parameters.
 I choose to use DoH with Cloudflare instead of the given DNS.
 Internet worked perfectly.

- On 2023-12-06 and 2023-12-07, same parameters, Internet worked perfectly on another network. - Since 2023-12-08, Internet is very slow. It need about 1.5 minute to get start.duckduckgo.com loading on any network.

 I thought it will not load at all (timeout ?).
 Others webrowsers (e.g. : Microsoft Edge) are correctly working.
 The "ping google.com" command is working normaly on windows with 2ms delay.
 The DNS on windows "Get-DnsClientServerAddress" are the normal DNS of the router.
 Even with reverting the DoH parameter to off, I do not get back my web browsing speed.

Troubleshooting :

- It's slow with "DoH and Cloudflare" activated.

 It's slow on my home network.
 It's slow on a public network.
 It's slow on another private network.
 https://www.dnsleaktest.com gives me a list of Cloudflare DNS (IPv4) near me, different from the DNS (IPv6) used by Windows 10.
 Meanwhile, Microsoft Edge, ping and wget/curl are working normally (i.e. no delay).
 Noticably, Microsfot Edge use by default according to https://www.dnsleaktest.com the same Cloudflare DNS.

- It's slow with "DoH and Cloudflare" NOT activated.

 It's slow on my home network.
 It's slow on a public network.
 It's slow on another private network.
 https://www.dnsleaktest.com gives me one DNS from my ISP (IPv4), same value as the DNS (IPv4) used by Windows 10.
 Meanwhile, Microsoft Edge, ping and wget/curl are working normally (i.e. no delay).
 Noticably, Microsfot Edge use by default according to https://www.dnsleaktest.com the Cloudflare DNS.

- In about:crashes there is not relevent crash (only old crash).

- I have not changed any about:config parameters in the 2023-12-05 to today (2023-12-12) period.

- I have run mozregression GUI with no problem.

 The program oppened succesfully start.duckduckgo.com .
 This website was choosen as it is an allowed website on every DNS.

- Firefox 120.0.1 is saying that it is up-to-date.

 And as of today, it is.

- I do have some extensions (12 activated) on my Firefox, so I try without extension.

 It worked but I do not understand why!
 * New profile. Using "firefox.exe -profile" I created another clean profile to see.
                It worked.
                According to https://www.dnsleaktest.com, my new empty profile uses both Cloudflare DNS (IPv4) and the router DNS from the ISP.
                Adding one-by-one most of extensions (6 now) to this new profile do not break yet my Firefox speed.
 * Safe Mode. Using "firefox.exe -safe-mode" I have started my corrupt profile without extension, JIT, etc...
              It worked.
              According to https://www.dnsleaktest.com, it uses only the router DNS (IPv4).

- I can send some result from about:support if needed, but it kills privacy...

Conclusion :

I do not understand why my main Firefox profile is not working correctly. I do not see strange things when troubleshooting. Nothing makes sense.

May someone help me figuring out?

What can I do to get my "upgraded" Firefox to display Facebook correctly. Right now, it is basically a blank page. Edge still displays Facebook correctly. Please try to give instructions that a non-expert can follow.

After the most recent MAC OSX update ( ) all of my fonts in Firefox have changed to a weird arabic font or something. I've un-checked the "allow website to select font" option and gone so far as to completely uninstall and reinstall FF (removed cache, application data, etc).

If I can't figure out what the heck is going on, I'm about to ditch this and switch to Chrome. Please help. ScreenCap ScreenCap

Firefox is my browser, and Outlook my email program. After years of troublefree access to Kickstarter, I now cannot link to the site, neither by Google search, nor by responding to an email link sent to me by Kickstarter. Instead, I get a message which reads:

'You are sending too many requests to Kickstarter at this time. Please contact support@kickstarter.com if you continue to see this error.'

I have contacted Kickstarter, but their response is that the problem probably lies with my browser. Do you have any idea why this problem should suddenly have appeared?

All items except but the top one (privacy) in the right-side menu in vimeo are partially hidden and so not fully functional. This problem does not occur in Microsoft Edge, and so it evidently is a Firefox problem. My system: AMD 3900X Running Windows 10 Home, Nvidia GTX950 graphics card, 32 GB memory, The image is a reduced-size screenshot from a 1920 x 1080 monitor. Adjusting the width of the window for Friefox has no effect on the problem.

Can someone please alleviate my sudden sudden onset of paranoia and tell me that this is what I suspect it is? That it's just your standard dev tools any user would have, and that a company could configure in deployment to work phones. I exceeded my IT tech talk comfort-level about 32 words ago, and now I'm faking it. I'll try to project confidence.

I don't believe I've ever used InTune on any personal device, but I have on work phones in the past. I mention InTune only because the last time I did use it to load company apps onto a personal phone was in 2016, and it would feel pretty creepy if this had managed to migrate across several years and several organizations to land on my new phone. And, to be clear, I really didn't get uncomfortable until I saw the apps under Flagfox, with an IP tracker, etc. I have a couple exes who have psycho exes; the kind who manipulate their child into putting a keylogger on their ex-wife's machines.

Screenshots in order of rising alarm and intensity of goosebumps.

Thanks- Dave.

LoL... As soon as I hit Share Data, I see those apps bringing up my data to help you troubleshoot, thereby answering my question, but I'll post it anyway. Hopefully, someone gets a laugh out of it.

Hi,

There seems to be many Firefox processes running which consumes large amount of CPU and memory (attached) - I have only opened a single instance of Firefox however there seems to be problems with this. I end Firefox processes and start anew, however it appears the same. I restart the computer and open firefox it appears the same. I'm not sure whats going on. This is impacting my PC performance negatively.

Hi,

It hard to explain what I mean so I recorded video, link is below. I want Firefox to behaves the same as Chrome. So as you can see, when I use address field for quick search then pop-up appears with search results. And I click on these search results with middle mouse button. But on Chrome it works normally and on Firefox not. I am redirected to just opened tab what is really annoying. I must go back, input the same if I want open several result. How to change this behaviour to achieve the same what I have in Chrome?

Chrome Firefox Serach Behaviour

Also it’s exactly the same when it comes to bookmarked pages in a folder on the bookmark bar. When we click folder with bookmarks we have dropdown menu with bookmarked web pages from this folder. And when I click something with middle mouse button then page opens in new tab but this dropdown menu disappears, and again I must click folder when I want open more sites. In chrome it doesn’t. How to set it the same for this?

Themes do not stay locked since several updates back. It is ridiculous that every time you open the browser you need to go to settings and get 'dark theme' back on, when it is the only theme many of us with visual problems can use. MANY people have complained about this (read your own reviews). FIX IT! It's doubtless a five minute job to put this back the way it was.

When I open firefox it opens on the "success" page it should open on my selected page Yahoo.com

this happened after I ran the "refresh firefox" option
