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!

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.

I'm the I.T. Director for a school and we use the Securly filtering system. I can't get Firefox sync to work behind this filter. What is the URL that Firefox is trying to connect to for sync so I can add it to the whitelist? Or, IP address. Also, does Sync use my system DNS or does it have some sort of internal DNS that it queries for sync? Because I recently found out the hard way that I have to use the Securly's DNS IP's or nothing works.....

There are certain websites that, on firefox only, display apostrophes and quotations as Russian letters. For example, on google docs, if I type "He's such a great friend" it will display уHeТs such a great friendФ. When I open the document on the app, it is normal, but I haven't been able to figure out why it does this on my computer. I use Mozilla Firefox for Fedora 149.0.2 for reference.

I recently bought a new laptop running on Windows 11 Pro. All my settings for languages (English GB) in Firefox are the same as my old laptop, which was Windows 10.

On my W11Pro laptop, the translation icon doesn't appear when I highlight a portion of text in a foreign language, whereas it did appear in my old laptop. If I right click on the highlighted text I can access "translate selected text" but nothing happens when I click on that. Translating an entire webpage works fine, it's just the highlighted text that doesn't.

I'm not very technically minded, so any answer will need to be in simple terms! Thanks.

Over the years I've added dozens of additional search engines; periodically I've "archived" lesser used search engines by toggling their visibility (to reduce clutter and speed up my search process), and when an "archived" engine becomes relevant to me again I've simply toggled the engine back to a visible state. However, as of version 152, this functionality appears to have been removed for user-added search engines. Is there a way to restore this functionality?

I've searched here and elsewhere on the web for a workaround, and perused the about:config variables, but have not been able to find anything. The show/hide functionality is still present for builtin search engines, so it seems like there must be some way to restore it for all search engines.

Thanks in advance for your help!

Hi team,

I am facing a persistent video playback issue specifically in Firefox (latest version), while the exact same stream works perfectly fine on Google Chrome and VLC player.

When I try to play a high-definition HLS live stream from my network provider site (vraitv.com), the video stalls and buffers every few seconds. Upon inspecting the Firefox Web Developer Console, I notice frequent NS_ERROR_NET_TIMEOUT errors during the loading of .ts video chunks, along with occasional CORS warning flags.

I have already tried the following troubleshooting steps:

1. Disabled Enhanced Tracking Protection for the site. 2. Started Firefox in Troubleshoot Mode (Safe Mode) with all extensions disabled. 3. Cleared all cookies and site cache.

Unfortunately, the issue persists. Are there any hidden settings in about:config (such as modifying network.http.max-persistent-connections-per-server or increasing the media cache size) that can optimize how Firefox handles concurrent video chunk loading?

Any technical guidance would be highly appreciated.

Feedback on Firefox Widgets – Missing Indian Standard Time (IST)

I noticed that the World Clock widget includes Pakistan Standard Time (PKT) but does not provide an option for Indian Standard Time (IST). This is surprising given that India has one of the world's largest internet user bases and a significantly larger population than many countries currently represented.

India operates on a unique UTC+5:30 time zone used by over 1.4 billion people, making it one of the most widely used time zones globally. The absence of IST while neighboring time zones are available feels like a major oversight and reduces the usefulness of the widget for Indian users and anyone who regularly works with Indian colleagues, clients, friends, or family.

Please consider adding Indian Standard Time (IST) to the World Clock widget as a standard option. Its inclusion would greatly improve the widget's global coverage and usability.

Good morning, When I load a TastyTrade Website: The Firefox browser starts blinking black and white and never loads the page. I tried troubleshooting myself:

- Open Settings → Performance. - Uncheck the two enabled options. - Reload the browser.

It worked once, but when I reloaded Tasty Trade, the problem returned. Please advise. Thanks.

Hi,

The Firefox browser came through with an update and I found that on Bluesky it is hard to load or see video's, which makes it a slightly pointless exercise.

Previously I have found that after an update (can't recall if it was Chrome, but think it was Firefox) the problems cleared up after a couple of days.

However, that doesn't seem to be happening right now.

Can't think what I should be tweaking at my end.

Firefox is my browser, but I also have Windows Office 365. Every time I open my my gmail account or anything else I have to reset Firefox as my browser. Windows keeps trying to change my browser. I use and have many documents on Office 365 so I don't want to delete it. How can I stop that from happening. I can't disable the Microsoft browser.

On Linux Mint 22 on my desktop, the buttons in the RH top corner are tiny. I have measured the minimise line and it is under 2mm long.

I have tried various searches to see if these controls could be made larger, but most questions suggest changing the theme. I don't want to do that, and I'm sceptical that it would make any difference anyway.

Has anyone got any suggestions how they could be made bigger?

I'm using the MATE desktop.

Thank you

when searching from the address bar (see picture) the first result (before firefox suggests) is not a bookmark and not history. what is it and how do i get rid of it? I want bookmarks to always be the first result. I just went through the library and it doesn't appear in history/bookmarks. thank you
