Firefox Community Forum

I am a pensioner in te UK. Due to restricted mobility I spend a lot of time using Firefox to access many web sites. This normally works perfectly. Today I tried to access the web site of national chain store specialising in outdoor clothing and equipment because I need a new showerproof jacket. I have never used that site before, yet Firefox reported Error 403 : Forbidden. Have you people never been told tat error messages are supposed to be useful? What is Forbidden. Why when it has not happemed before?

The web site is https://www.millets.co.uk/

I have a web site so I have other browsers just for checking for layout problems.

I tried Chromium, same error but the message said You are not authorised to access this site. Presumably that is what your incompetent message should have said. But why should a pensioner trying to buy something from a chain store ever need any sort of authorisation?

I tried Opera. Connected me no problem!

I tried Edge. Connected me no problem.

Clearly somebody somewhere is an incompetent idiot, but it isn't me. So who is it? If it is yourselves then please do something to fix this.

При заходе на сайте ya.ru и если на нём имеется строка с видео или поиск с алисой, то начинаются сильные фризы. Это ошибка именно в firefox 142, проверенно.

For the last few weeks I have been unable to save new bookmarks into the folder of my choice. Instead I can only save new bookmarks into the last folder I created. I cannot navigate to a different pre-existing folder. This problem only occurs when using Firefox on my Android cell phone, but not on my PC. However, I can still view and use all of my previous folders and bookmarks when wishing to open a new website, per usual. Thank you

I have a Brother DCP-L2550DW printer that is connected via a network cable. Any other browser, i.e. Edge or Chrome, seem to be able to connect and print just fine. Firefox fails to print and there is no information about why. I have checked Event Viewer, turned off all the extensions, tried the about:config to reset printer options. Every single suggestion I've found so far fails to fix it. I have a great deal invested in using Firefox (bookmarks, etc.) so I'd like to keep it as my default browser, but not being able to print is SO annoying. Any suggestions?

Reader view doesn't work on many Lifehacker pages/articles. Can something be done to make it work on those pages? Here's an example:

For some reason all of my bookmarks are gone. I have tried all the suggested fixes and it's still not working. Don't know where they went but I would sure like to have them back. Plus, now when I try to bookmark a page its not accepting it. :(

One of the recent updates changed Firefox's behaviour. It now remembers my login status to various sites when I close the browser. For example, if I was logged in to facebook when I closed the browser, I will be logged in when I open the browser and navigate to facebook.com. This was not the case until very recently (a few weeks at most). Is there a way to change this?

I have strict privacy settings, and Firefox should delete all cookies when it is closed. There are no 'exceptions'. I have 'always use private mode' checked for history. Also: I haven't changed any settings recently - something changed in Firefox.

Any advice? Thank you.

Hello all!

I've started having an issue in the last few days, with apparently two separate Firefox installs. A few days ago I was greeted by a fresh, blank install of Firefox and had to set everything up and sign in as I usually would on a fresh system install. Today, however, I somehow managed to launch both of them at once (I don't know how, as I just use the UI shortcut). After closing both fully, I can now only start the "old" one via the shortcut.

OS: Bluefin / Fedora 42.20, Gnome 48.6

According to the list of flatpaks, only one is installed. Unfortunately that's roughly where my knowledge of Linux ends, so I can't troubleshoot this further. Help will be apprecciated, as I don't want to roll a die on which of these will start up every time I reboot.

Kaspersky just found this hidden in the Firefox cache folder and the funny part is that I don't even use Firefox that much. I didn't visit any sites on this particular Firefox except Facebook. So, what sort of malware is this? A Trojan stealer or a dropper of some sort? I am running a Full Scan for now and I have uninstalled all the browsers incl Firefox, Chrome. Detection name: Trojan.JS.Agent.exz

The details of Detection: Event: Object deleted User: DEMON-SLAYER-2\....... User type: Initiator Application name: avpui.exe Application path: C:\Program Files (x86)\Kaspersky Lab\Kaspersky 21.22 Component: File Anti-Virus Result description: Deleted Type: Trojan Name: Trojan.JS.Agent.exz Precision: Exactly Threat level: High Object type: File Object name: 2309DFD956392BDFD0C84CA455FF6426B6B0FA9F Object path: C:\Users\......\AppData\Local\Mozilla\Firefox\Profiles\i2607jtb.default-release-1739822052193\cache2\entries MD5 of an object: 6FEC3D1DC6D1802AEADC4F8611A9F326

Since this is a Trojan, can this be Dangerous? I scanned it in virustotal and 33 engines were saying malware.

After I disabled ws2ifsl in the Registry Editor, problems began to occur when launching Firefox: as soon as I clicked the mouse after starting Firefox, it would become unresponsive. Even re-enabling ws2ifsl or refreshing Firefox was of no avail. No matter what I did, it would enter a completely unresponsive state as soon as I clicked the mouse. Do I really have to reinstall Firefox? Note: This is for the Windows version.

Neither the [`

So how do I get them running? A significant portion of the internet runs on WebM and the fact that Mozilla's own dev docs can't show examples is a good indication of a problem.

I'm using the AI Chatbots plugin in the sidebar and I'm trying to log into Claude, but the plugin keeps asking for a verification code and Anthropic only sends a magic link email which doesn't work in this situation.

whenever I do a Firefox update, there sometimes is a new extension included that I personally feel no use or need for..most of the time I can disable them w/programs like Ccleaner (see image), but some are persistent, and return the next time I open Firefox. Firefox always consumed a significant portion of my 8gigs of RAM, and my latest update to 144.02, it is approaching 15%. Any way I can stop this short of reverting back to previous version?

Hello I am having major problems with Firefox at the moment and have done for a while. I curently have four pages open but as you can see from the attached screen shot of my Task Manager, there are 14 Firefox processes. The usage is OTT on memory and everything else. Could you tell me why this is happening? Currently it is running in Troubleshooting mode but that is not doing anything to improve the problem. It has been known to shut my computer down, as it gets too hot. I run on Windows 10 and Bitdefender is my security. All help is gratefully received. Thanks Lisa

A bit over a month ago, I was away from home for several weeks. When I came back, a browser that worked perfectly before became near unusable with constant and random crashes. Sometimes they occur even with no user input. I have tried troubleshooting mode, I have removed all extensions, I have tried all the fixes I found on Google, I have reinstalled the browser, I have updated all the drivers, I have done MemTest86 which was passed with flying colours and I have even installed a firefox fork (waterfox) to try and fix this all to no avail. I have no clue where to go from here, as it feels very bizarre. All help is much appreciated.

Is it possible to sync all profiles among different devices? So they are tied to your mozilla account, then you get the option to choose which profiles to add on a different firefox browser. Mac and windows for example.

Also it would be nice to be able to change the "banner?". Basically the thing surrounding the profile image.

I am FURIOUS with the latest update! I put my computer on "Sleep" for a couple of hours this morning, and when I cam back to it, the screen was locked up and I had to restart my computer. When I finally came online, everything had changed! I've had multiple Windows with lots of tabs running without any problems for a LONG time, until today! Now, EVERYTHING IS GONE!

Websites like Medicare.gov give message like "We can't process your request at this time." This happens with increasing frequency on pages I know are valid and secure. MS Edge opens them with no problem.

Another example - my bank web site. Firefox triggers a whole series of confirmation tests from them but Edge gets in with just ID and password.

I am using a VPN from Malwarebytes. Windows 11 is the OS. Latest version of Firefox is installed (144.0.2 (64-bit))

I have been a long time Firefox user, but am starting to drift away to Edge because it connects to more web sites with less hassle.

What are my options?
