Firefox Community Forum

Hi!

I am getting messages that I am blocking ads for many of my internet requests. I had never received these before but all of a sudden I started to get them. I have tried a number of things but nothing works.

I am running Windows 11 and do not have any Ad blockers.

Opening PDFs automatically with Firefox and, without any changes I might make, saving them with the download function in Firefox, actually ruins the functionality and data entry function of that file. Specifically this happens with PDF files downloaded from the (not all that amusing) PDFs from the FINCEN, (US Financial Crimes Enforcement Network). I do not see why and how Firefox thinks it is allowed to change files that are simply downloaded and saved on Firefox.

In other words, it seems that Firefox strips away certain "permissions" and/or "functions" (like built-in lookup, menu or choice boxes). This means that the file so downloaded via Firefox can no longer be used to properly fill in data, or to look up and choose data items within the file. (I see many times that ANYTHING having to do with "permissions" tends to be an intractable and unsolvable problem for software makers & experts, so, if you do not know right away how to solve the problem, it will probably take you several years to figure this out.)

The PDF in question is created by a government agency. If you have ever dealt with a government agency, then you know that they act sort of like Adobe or Microsoft: "They don't respond, or they do respond & say they do not understand, and if they understand, they are either unwilling or unable to fix the problem."

If there is a switch or option within Firefox, which lets me tell Firefox "Save this file exactly like it is received, nothing added or removed!", that would be nice. I just have not found such an option yet, and it would be nice if it might get provided someday.

I will share my browser data, but I am sort of convinced that a detailed question like mine will not be addressed within that shared data.

Hi everyone, I run a website, which provides information about mobile phone prices and SIM packages in Bangladesh. I’ve been working on improving page load speed using LiteSpeed Cache and Cloudflare CDN. While it works well in Chrome, I’ve noticed that Firefox doesn’t always cache pages or static assets (like images and CSS) as effectively. Does Firefox handle cache-control headers or service workers differently than other browsers? I’d also love any advice on best practices for implementing browser caching or service worker scripts that improve performance on Firefox without causing outdated content issues. Thanks for your time and any insights!

I recently upgraded my Router to an ASUS AX5400 and when I tried to sign in t the configuration site (192.168.50.1:8443) Firefox prevents me from proceeding due to an incorrect or non authorised site. What I find most annoying is that not only does Firefox issue a warning (that's fine) but there is then no way to proceed by accepting the danger (none in this case) and proceeding to login to my own Router that I have just purchased. So, the only way to set up and subsequently administer my Router is to use either MS Edge or Brave who provide a warning but then allow me to accept the risk and proceed to the Router's configuration settings. ASUS do provide a Certificate which I have added to my Trusted Root Directory and also to the Firefox Certificate repository but apparently, for reasons I don't understand, the Certificate, although issued by ASUS, is not signed by a certified authority that is acceptable to Firefox. Does anyone know how to get around this problem using the Firefox browser? Just why Firefox think it is OK to block me from accessing my own Router is beyond me!! This is equal to the arrogance often displayed by Microsoft i.e. we'll give you what WE think you need not what you need. By the way - I have also written to ASUS to ask them why on earth that don't issue a suitable Certificate for a $250 Router.

When I try to open a link using Mac Mail "open link behind mail," the new tab in Firefox opens in the foreground. ChatGPT tells me this is a Firefox related issue and is giving me a bunch of about:config alterations to try, but they don't work.

Is ChatGPT leading me astray, hallucinating?

Is there a Firefox fix? This is a new problem. Is it a bug? Thanks.

Firefox did an update and "couldn't find XPCOM" and crashed. Uninstalled and re-installed but now my Firefox icon opens a website "nine.com.au". I WANT MY FIREFOX BACK!!!!!

Hi, I updated to Firefox 146.0 this past week and immediately noticed that the UI elements (scrollbars, sidebar, tooltips, etc) are once again in dark mode; the main websites window and the firefox settings remain in light mode (as set by my user preferences). I've been using browser.theme.toolbar-theme and browser.theme.content-theme to force light mode of all UI elements regardless of theme and as of this last update they have stopped working (editing them to any value of 0,1,2 does not make a noticeably change to the UI). What internal setting changed to stop firefox from using the browser.theme.(etc) settings and what can I edit to get them back? Thanks, Bre

Hello,

I'm trying to access a dropdown menu on trafficjunky.com but the menu is not functioning correctly and will not load. When I select the dropdown, it opens a small blank white box that should fill with options, and I should have the ability to free type as well so I can search for a location. This does not happen, the only thing that happens is what you can see in the picture and free type is not functioning.

I have cleared cookies and cache numerous times, updated my browser, deactivated extensions, turned off performance settings, and have tried both troubleshooting and incognito modes as well. I am not running ad blockers or themes on Firefox.

Any advice you can provide is appreciated!

Thank you, Kyle

So within the last couple of days Firefox has started toggling the menu bar even though I have it disabled/hidden. If I were to click off of the browser to check Discord for example, it pops up when I click back on and literally moves stuff down--which makes it annoying if I try to click back on to enter a web address.

Anyone else having this problem?

Hello. My macBook recently died. I was signed into Firefox, so my tabs should have saved. I tried to open / upload them onto my new iMac desktop. But for some reason it only keeps wanting to mirror the open tabs on my iPad, which is not what I want. I want to resurrect the tabs open on my macBook before it died. How do I best do this please? Thanks

I use Firefox every day at home and at work, and I really need to separate different content across many profiles between devices. Can I access the features of the new profile manager please?

I have had Google today almost lock me out of my account there thru various email accounts I have with them because they were not recognizing my devices that I always use daily and have for months and even years because of cookies that I don't delete and because I was not on the same browsers or accounts each time which I was unaware that I had or should stay on the same. So could I through you find out how to delete cookies that I have/had accepted in the past?

In Settings>General>Language, why is there an option to "Use your operating system settings for “English (Zimbabwe)” to format dates, times, numbers, and measurements." . I can't find any documentation for this. Is there an interesting 'Zimbabwe' format or feature? If so, what is it?

Do I need to add an email filter?

Had to recently reset my browser and lost all my history. Apparently it messed up my custom settings in some way as well.

New Tab still shows my FF homepage with shortcuts and history gone - I've managed to get those back but with one huge problem:

- Clicking on a shortcut opens it in the same tab, whereas earlier I had it working when clicking on a shortcut would open it IN A NEW TAB.

Where's the setting in about:config to fix this???

If this feature has been removed - why???
